00:17

The behind-the-scenes tales of hit productions and creations from Japan.

00:21

This is "Japan's Top Inventions."

00:27

On today's show, laptop computers.

00:31

They're used all over the world.

00:36

But did you know a Japanese company created the first mass-market laptop?

00:45

Later on the program.

00:47

There's a special powder in this component.

00:53

It's actually something used in laboratories worldwide.

00:56

What could it be? Stay tuned to find out.

01:05

Hello, welcome to "Japan's Top Inventions."

01:08

I'm your host, Jason Danielson.

01:11

In the first half of our show, "Behind the Creation,"

01:14

we go behind the scenes and discover how Japan's top inventions were made.

01:19

Today's topic.

01:20

Laptop computers

01:22

developed by a Japanese company in 1985.

01:26

At a time when only desktop computers were readily available,

01:30

one company succeeded in creating a compact device

01:34

light enough to carry with a screen and floppy disk drive.

01:38

It created a huge new market for portable computers.

01:42

The team of engineers that made the laptop

01:44

had actually been ready to pull out of the computer industry.

01:52

An electronics retailer in Tokyo.

01:55

The latest laptop computers from a variety of manufacturers are on sale here.

02:04

In 2021, 340 million laptops and other computers were shipped.

02:10

They've become an everyday part of life.

02:20

The model that played a part in kickstarting this giant industry

02:24

is kept in this company's building.

02:30

This is our company's first laptop computer.

02:38

The initial model was developed in 1985.

02:42

It's around 30 centimeters in size, and weighs 4.1 kilograms.

02:50

The laptop was recognized by a prestigious engineering association based in America.

03:00

This is from the Institute of Electrical and Electronics Engineers,

03:04

the IEEE.

03:06

They declared our laptop a pioneering contribution

03:10

to the development of portable PCs.

03:16

We share this honor with all the employees of the company.

03:24

Our story begins in the 1980s.

03:32

It was a time when desktop computers made by an American company

03:36

were becoming common in offices around the world.

03:46

Manufacturers all over were looking to develop their own products

03:50

and put them out to market.

03:57

This major Japanese tech company was part of the competition.

04:05

But they had entered the market late,

04:07

and competition was fierce.

04:09

There was talk of shutting down the computer department.

04:19

Could nothing be done?

04:21

The company desperately looked for ideas

04:24

and came across an interesting concept.

04:32

An American computer scientist had proposed his vision

04:35

for a "personal computer."

04:39

He believed a computer had to adapt to people

04:42

and support their lifestyles.

04:51

This is Kashiwagi Kazuhiko

04:53

who oversees the company's computer business.

04:56

Here's what he heard about the time.

05:03

Alan Kay, the American scientist,

05:06

had a vision for a small computer that he called a Dynabook.

05:12

Rather than humans obeying the constraints of computers,

05:16

he wanted them to fit into our lifestyles,

05:19

to be simple enough for a child to use.

05:24

He envisioned the modern personal computer

05:27

decades before it actually existed.

05:32

Computers at the time were in set locations.

05:35

You did specific tasks on them

05:37

and returned to your desk after you were done.

05:50

The developers wanted to turn the desktop computer

05:53

into something compact and light.

05:59

If it was portable, you could do the work whenever and wherever you wanted.

06:04

That kind of flexibility would make it a true personal computer.

06:14

With the concept in place and the survival of their department on the line,

06:18

the development team got to work transforming the desktop computer.

06:29

How to make a small computer.

06:32

The team started with the main body.

06:40

They decided on a size that was suitable for carrying.

06:43

The internals would come after.

06:50

For this project,

06:52

the team determined the external design first.

06:58

If we had started with the insides instead,

07:01

it would be too tempting to settle on something larger.

07:06

After deciding the size, there would be no compromises.

07:10

We wanted it to be truly portable and convenient to use.

07:14

So we picked the size and designed the insides after.

07:20

But there was another problem, the computer's display.

07:26

How could they make it portable and include something so large?

07:35

The team evaluated their options.

07:38

Their final idea took a cue from these.

07:48

Seashells.

07:50

They would use the so-called clamshell design.

07:58

The main unit would have a built-in rechargeable battery,

08:01

keyboard and a thin LCD display.

08:04

The screen would close like a clamshell for transport.

08:14

The entire unit was smaller and thinner than a desktop.

08:17

But they would still need to fit around 1,000 components inside.

08:28

The team started prototyping right away.

08:31

They soon hit a snag,

08:39

the motherboard.

08:40

Their design required a smaller board,

08:43

and it would need to have fewer components on it.

08:51

The developers tirelessly searched for options.

08:54

They came across a company

08:56

that had successfully created smaller chips

08:58

by packing in more transistors.

09:06

After contacting the company,

09:08

they were able to secure a supply of these components.

09:15

With the new chips in hand,

09:17

all the necessary components would fit on the board.

09:21

The new design had the same capabilities as a desktop

09:25

but was less than half the size.

09:31

The development team was dedicated to making the computer light and compact.

09:35

But in order to finish their product,

09:37

they still had to figure out a way to incorporate this,

09:41

the floppy disk.

09:45

At the time, software was not yet stored on the computer itself

09:49

due to a lack of memory.

09:51

Something external was used.

09:57

Floppy disks.

09:59

Programs such as word processors and accounting software

10:03

were run off these disks.

10:15

The new device would also need a floppy drive,

10:18

but they had to save as much room as possible.

10:27

The team looked towards these.

10:29

3.5-inch floppies, the smallest on the market.

10:40

But the software companies were all putting out their programs

10:44

on the larger 5-inch disks.

10:46

If they managed to build in a 3.5-inch drive,

10:49

there still would be almost nothing available on the smaller floppies.

10:56

At the time, almost all software was distributed on 5-inch disks.

11:02

Even if the team went through the effort to fit in a 3.5-inch drive,

11:06

there would be nothing to run on it.

11:10

If programs weren't available on 3.5-inch disks,

11:14

then the computer could end up just becoming a useless box.

11:22

The team headed for America

11:24

to meet with the top software developer at the time.

11:32

The developers were confident

11:34

that their new design would soon become commonplace

11:37

and asked whether the company could release their software

11:40

on 3.5-inch disks.

11:46

The team visited a very major software company

11:50

but were basically turned away at the door.

11:53

But they persisted and visited many times,

11:56

explaining over and over again what laptop computers were capable of

12:01

and how popular laptops were going to be in the future.

12:10

The team members spoke with several companies,

12:13

and through persistence,

12:14

they were able to establish a strong software lineup for launch.

12:22

In January of 1985,

12:24

the laptop was finally ready.

12:35

The developers decided to show off their device

12:37

at an international conference in Germany.

12:45

They wanted to gauge the reaction in Europe

12:47

before expanding to the American market.

12:55

The reason we chose Europe was because

12:59

the US is a single market

13:01

but there are many European countries.

13:05

It's true you have to adjust marketing for each country,

13:10

but the US is all or nothing.

13:16

So we thought we'd have a better chance in Europe.

13:19

And then we could decide what to do

13:22

after seeing how it was received there.

13:27

At the conference, the team did their best to show off their product.

13:35

But there didn't seem to be much interest.

13:44

As they kept trying, one man stopped for a look.

13:54

He was a procurement officer for a major German company

13:57

looking for new company computers.

14:06

It was a perfect chance.

14:08

Nervously, they handed him a unit.

14:15

The man placed the device on his lap and flipped open the display.

14:19

He was very impressed.

14:25

But could it run the kind of programs

14:27

his company needed off a floppy disk?

14:35

It was the moment of truth for the developers.

14:38

They handed him a disk to try.

14:55

With bated breath, they waited.

15:16

A moment later, the accounting software loaded.

15:26

The man tried the keyboard.

15:33

The device responded right away.

15:42

The software ran perfectly.

15:45

I think that really made an impression.

15:49

The device tapped into a hidden demand

15:51

among people working in the office.

15:55

They wanted to be able to move the computer

15:58

and work somewhere else.

16:01

It was convenient to be able to do that.

16:05

No words of mine could express how happy the team

16:09

was with the success.

16:12

They would've had to keep a straight face,

16:15

but I bet everyone was jumping for joy on the inside.

16:22

The value of the laptop computer had been recognized.

16:29

10,000 units were shipped in Europe after just one year,

16:33

and the company began selling in America soon after.

16:45

And that was how the company was able to create

16:47

a new market for portable laptop computers.

16:50

It's been about 40 years since they hit the market.

16:53

How do experts view the significance of this model?

16:56

Let's speak to IT specialist, Toda Satoru to learn more.

17:01

Welcome to the show.

17:03

Thanks for having me.

17:05

What was the significance of this laptop

17:07

when looking at the history of personal computers?

17:11

A laptop computer was something of a niche product at the time,

17:15

but nowadays it's something for everyone.

17:18

I think it's safe to say, that first laptop was a game changer.

17:24

The laptop gave birth to a new way of doing work.

17:27

In the past, you had to go to the office

17:29

and use the computer there in order to do work.

17:33

But with a laptop, you can work from home.

17:37

This might be a bit of hyperbole,

17:39

but I think that's a huge change for humanity.

17:43

Would you say that when computers became portable,

17:45

it was the first time that people were fully in control of the device?

17:50

Computers used to be very inconvenient.

17:53

With a desktop, you're tied to one spot.

17:56

You loaded data off the floppy disk,

17:59

but it wasn't convenient to use.

18:02

They demanded effort from the user.

18:05

But computers became smaller and faster.

18:09

And now, in the last 10 to 15 years,

18:12

they barely leave our side.

18:15

As the computer became lighter and more compact,

18:18

we started keeping them around,

18:20

ready for use whenever we need.

18:22

What do you think is next for laptop computers?

18:26

I think they're going to look pretty much the same,

18:29

but the role of AI on the software side

18:32

is going to be much bigger.

18:34

For example, I think translation software

18:37

that's been regarded as a bit unreliable

18:40

is going to be basically perfect.

18:43

So in online meetings between people from different countries,

18:46

they'll all speak in their native languages

18:49

and it'll translate what they say immediately.

18:52

If it's like that, I think meeting online is going to be plain

18:55

better than meeting in person.

18:58

This kind of thing is what computers are good at,

19:00

so I think things will keep moving in that direction.

19:03

Interesting. Thanks for joining us.

19:05

It was great talking to you.

19:07

Thank you.

19:12

"Top Niche Creations."

19:15

In the second half of our show, "Top Niche Creations,"

19:19

we discover Japanese products doing well in niche markets worldwide.

19:23

Today, we're looking at

19:25

a separation and purification system.

19:29

I'm sure not many of us have seen one of these before,

19:32

but devices such as smartphones, TVs and solar panels

19:36

couldn't be developed without their aid.

19:39

Just what exactly does it do? Let's find out.

19:46

A Tokyo company that makes analytical instruments.

19:52

It's a small company of around 30 employees,

19:55

but their walls are decorated with awards that recognize their products.

19:59

(Top 100 Global Niche Companies)

20:07

The company's representative product is this.

20:10

Just what does it do?

20:15

We asked Sales Manager Imai Hideto to find out.

20:21

Our device is able to extract target components

20:24

from chemical compounds and remove any impurities.

20:29

This is called separation and purification.

20:33

It's used by national research facilities.

20:37

You can also find them in the research departments of companies

20:40

that specialize in making things like

20:43

chemicals, materials and medicine.

20:48

This is the separation and purification system.

20:51

How does it work? We got a special demonstration.

20:59

These samples of red, yellow and blue water were prepared.

21:07

When mixed together, the water turns black.

21:11

The machine is going to extract the yellow for us.

21:20

Time for the demonstration.

21:22

The vials are set.

21:25

I'm going to inject the sample.

21:29

The black mixture is injected into the machine.

21:36

About six minutes later,

21:43

the process is done and the yellow has been extracted.

21:52

As you can see, only the yellow was separated from the black water.

22:00

The devices are used in research facilities

22:02

at universities and various companies.

22:07

These places study organic synthesis,

22:10

the combining of various chemicals into a useful organic compound.

22:20

Those compounds can be found in the latest OLED TVs,

22:27

or in these silicon compounds found in solar panels.

22:36

The difficulty with organic synthesis

22:39

is that impurities are also formed at the same time.

22:42

There needs to be a way to extract only what is desired.

22:49

How exactly does the device work?

22:56

The key component are these special columns on the side.

23:04

The samples pass through these columns,

23:07

and the unique properties of each component allow them to be separated.

23:16

After we were shown the yellow being separated out,

23:21

the red was also isolated,

23:25

and finally, the blue as well.

23:32

Just what is going on in these columns?

23:37

They're filled with a special type of gel powder.

23:44

Each particle of gel is only 0.008 millimeters.

23:51

Components can be separated based on their size.

23:54

The gel particles are full of tiny holes.

24:00

When a sample is forced through the cylinder,

24:06

the small particles in the sample briefly catch on the holes,

24:13

while larger particles are able to pass without catching.

24:20

Components are separated using this difference in time it takes

24:24

to pass through the cylinder.

24:27

The company also employs a unique method which involves recycling the flow.

24:37

By passing the sample through the column multiple times,

24:40

the target component is extracted with greater purity.

24:48

Sometimes the component isn't caught

24:51

the first time through the column,

24:54

but the chances increase tremendously with a second or third pass.

25:01

The company's device is used in 30 countries and regions worldwide.

25:07

A Swiss researcher, commenting on how hard it had been

25:11

to separate out a particular artificial sweetener,

25:15

declared it a "Japanese wonder."

25:19

We heard from the Swiss Federal Institute of Technology

25:23

that they had tried everything to separate

25:26

and purify a particular compound without success.

25:31

But our device was able to do it very easily.

25:35

They told us that our device had become essential to their research,

25:39

and that was extremely gratifying.

25:44

This device is also capable of separating out natural substances,

25:49

not just artificial ones.

25:50

For example, it can remove capsaicin from hot peppers,

25:54

the compound that makes them spicy.

25:56

Or it can extract the bitter catechin from green tea.

26:01

By isolating these compounds,

26:03

they can be used in supplements or other products.

26:06

The possibilities are limitless!

26:10

That's all for today's "Japan's Top Inventions."

26:14

We'll end by showing you how the engineers have continued improving the laptop

26:18

from the first half of the show.

26:20

Thanks for watching. See you next time, and Stay Inventive.

26:40

(New generations of laptops continue to be released.)

26:46

(37 years later... This new model is only 18 mm thick.)

26:54

(This one has a detachable display.)

26:59

(While this model folds back, changing into a tablet.)

27:05

(Developers keep on improving the laptop computer.)

27:11

Laptops mean so much to our company.

27:14

They're part of our vision. They represent us.

27:17

It's the soul of our company.

27:20

Customers want a product that's easy to use,

27:25

which results in us developing something that's thin and light.

27:32

We're going to keep creating computers

27:34

that assist people and make a positive impact to society.
