Since 1981 Health School

At 12 o'clock in the evening, in the dead of night, in the director's office on the third floor of Yuezhong Hospital.

Chen Qi personally made a cup of tea for Kaito Nimura, and then the two sat facing each other.

"Mr. Futamura, thank you so much for today's tender. Without your leadership, we would definitely not be able to easily win those medical equipment and drugs."

"I'm honored to be able to help Dean Chen. What's more, we are a family. Dean Chen doesn't have to see anyone outside, haha."

Chen Qi was also hehe. He and Xiaoli were a family. If this was announced, he wouldn't be called a bastard.

"Mr. Futamura, Nipro has the ability to produce 32-slice CTs, so I think you must also be developing more advanced 64-slice CTs. But now there are only three monopolies in the world: Shiba, Siemens, and General Electric. Your technology is stuck. Where?"

Seeing that Chen Qi had hit the point, Futama Kaito also answered seriously:

"Yes, our 32-row technology has matured. We have corresponding technical reserves for the components needed to produce CT, such as main bearings, slip rings, ball tubes, high pressure, etc. Even external procurement is very convenient."

It is very difficult for China to purchase the most sophisticated equipment in the world.

Moreover, even if there are no export restrictions on some high-end equipment, they will not sell it to you for money. This is very frustrating.

You are right to feel aggrieved, but should you be brave and have some backbone? If you don't sell it to me, I will sell it to you. I will build it myself at all costs and get the core technology.

(At all costs means should be used here)

Just like a photolithography machine has a total of 450,000 parts, it is obviously impossible for one country to produce them, which will inevitably require international division of labor.

What is produced in your country and what is produced in our country, we should communicate and complement each other. This is the correct international division of labor.

High-end equipment that cannot be purchased in China is a piece of cake for Japan.

But Japanese companies have a clear understanding,

That is, mid-to-low-end supporting equipment can be purchased, either domestically or abroad, or we can form an industrial chain with division of labor. You produce this and I produce that, and then assemble them. Even if they are assembled in foreign countries, it doesn’t matter. .

For example, many of Boeing's large aircraft are installed in China, and they are actively transferring low value-added, highly labor-intensive industries out of China.

But the core technology must be in your own hands.

That’s what they thought, and that’s what they did.

Chen Qi asked rhetorically: "So where is the current technical difficulty in producing 64-slice CT produced by Nipro?"

Futamura Kaito has already contacted domestic phone calls after the meeting, so he can still answer this question:

"The main technical difficulty currently lies in the detector. Do you understand, Director Chen of the detector?"

Chen Qi nodded: "I know that the basic components of CT detectors include collimators, scintillator, photodiodes and ASICs, so which key point are you stuck at?"

Chen Qi also looked through the CT instructions in the space operating room. Only by knowing yourself and your enemy can you win every battle.

"Nipro has mastered the collimator technology, and we have also reached a purchase agreement with our domestic Hamamatsu Photonics Company in Japan for electro-optical diodes. The current problem lies in the two important components of scintillator and ASIC.

Scintillator is a special material that emits visible light after absorbing high-energy photons. It is widely used in fields such as radiation medicine and nuclear medicine.

Therefore, it can be said that the scintillator is the heart of the detector and the core secret of CT. Our current material technology cannot reach it.

At present, 64-slice CT mainly uses ceramic scintillator.

The material used is GOS, which is a rare earth sulfur oxide. In Japan, only Shiba Corporation has mastered this technology. Their GOS detector is very advanced. In addition, General Electric of the United States and Siemens of Germany have this technology. .

Another technical difficulty is ASIC, which is actually an analog-to-digital converter, responsible for converting analog electrical signals into digital signals. The performance of the ASIC determines the performance of the detector, which further determines the X-ray dose and image quality.

Currently, only Xizhi, Siemens and General Electric can design this kind of chip. Their chips are not sold outside the market. Unless we can design them ourselves, we cannot get around them and there is no way to produce 64-slice CTs. "

Chen Qi understood the two difficult problems, scintillator and ASIC.

The difficulty with scintillator is the material patent. Other companies can decipher the material composition, but the three major companies have applied for patents, so you can't get around it.

Unlike India, it doesn’t matter what patent you have or not, if I want to copy it, I will copy it. I don’t need a visa to go abroad with Hu Jianren, as long as Mazu agrees.

However, patent protection in foreign countries is very strict. If you lose the lawsuit, it will really cost your life.

The difficulty of ASIC is chip design, but manufacturing is not difficult, because chip manufacturing is handed over to semiconductor giants such as AMS, Analog Devices, DT, and Texas Instruments.

For Japanese companies, as long as they give money, there will be no artificial obstacles.

After hearing this, Chen Qi nodded gently and had an idea in his mind:

"Mr. Futamura, you go back and rest first. The scintillator and chip design you mentioned are involved in our country's secret laboratory if nothing else happens. This laboratory is built in Shanghai. I can make mine overnight. My friend went to find the relevant finished product.”

Futama Kaito didn't believe his ears and asked in surprise:

"How is this possible? How come China has already conquered the flash body and chip design technology? If you are already so powerful, why don't you build a more advanced CT machine yourself?"

Chen Qi shrugged and pretended to be helpless and said:

"In fact, this dilemma is the same as that of endoscopy. You also know that our country is all about politics and is not very sensitive to business. Many good scientific research projects are successful, but they often like to publish a paper and then shelve it. Apply for a patent or something.

Another one is that producing a CT requires many components. No company in the world produces 100% of all components in-house and needs to be purchased externally. But the parts you can purchase cannot be purchased by us in China, and we cannot fully manufacture them ourselves, so we cannot produce them.

Mr. Futamura, don’t forget how your large computer system Showa 1 came about. "

Nimura Kaito now understood and completely believed Chen Qi's "nonsense".

This happened in 1982. At that time, China independently completed the manufacturing and research and development of the Great Wall 1st generation mainframe and the Dawn 1 supercomputer. In this supercomputer technology, China was far ahead of Japan and the United States.

Then, just to show off and demonstrate national strength, China naively took the Great Wall 2-generation mainframe computer and important technical data to participate in the "New York International Science and Technology Expo" and the "Tokyo New Technology Exchange Conference".

In Tokyo, when the Japanese discovered that China's computer technology was far ahead of theirs, they carried out a very ugly technological fraud against China, falsely claiming in the media and at various academic conferences that "the Great Wall is already a very backward product."

The experts were so angry that they began to refute, and even showed a complete set of top-secret information to the Japanese experts, and even allowed them to make copies and take them back to study slowly, in order to show that we gentlemen are magnanimous and have a clear conscience. This is exactly what happened. It is said that the Japanese have their own ideas.

The Japanese successfully developed the so-called "Large Computer System Showa No. 1" in the second year using the information they defrauded the Chinese.

Japan's precision machining is indeed better than China's, the appearance is beautiful, and it is not as rustic as China. In the end, China had to give up the intellectual property rights of "Great Wall" and "Shuguang".

In the end, Li Gui defeated Li Kui.

Throughout the 1980s, Japan stole many advanced technological projects from China:

For example, integrated industrial automation projects, large-scale welding systems, fuel cell nanotechnology of the Institute of Chemistry, carbon dioxide nano-catalytic high-efficiency catalytic synthesis of plastics technology, carbon nanotube manufacturing technology, etc.

Even the secret recipe of Yunnan Baiyao was once stolen by the Japanese, but it seemed to have failed in the end because the founder of Yunnan Baiyao refused to reveal the real secret recipe to outsiders (including the Yunnan Baiyao Pharmaceutical Factory after the founding of the People's Republic of China) until his death... )

As for how these advanced technologies were stolen by the Japanese, except for some of them accidentally, most of them were betrayed by "dog men" like Chen Qi.

The fortresses were conquered from within.
