Since 1981 Health School

Chapter 724 Chen Qi is betraying the country again

 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, and Dean Chen doesn’t have to see anyone outside, haha.”

Chen Qi is also haha, he and Xiaoli are a family, if this is announced, he will not be called a bitch.

"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., and it is very convenient to purchase them from outside.”

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

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

You are right to feel aggrieved, but should you be aware of your shame and then 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.

　　 (meaning at all costs should be used here)

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

 What is produced in your country, what is produced in our country, everyone communicates and complements 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.

  However, 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. .

Many of Boeing's large aircraft are installed in China, and they have taken the initiative to transfer low value-added, highly labor-intensive industries out of China.

 But the core technology must be in your own hands.

 That’s what they think and do.

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

 Nimura Kaito has already contacted the domestic phone number 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.

“We at Nipro have mastered the collimator technology, and we have also reached a purchase agreement with our domestic Hamamatsu Photonics company 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.

So 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-row 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.

At present, only Xizhi, Siemens and General Electric can design this kind of chip. Their chips are not sold outside. Unless we can design them ourselves, there is no way around them, and there is no way to produce 64-row CTs. ” ˆ ˆ Chen Qi understood, there are 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 and you cannot get around it.

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

 However, patent protection in foreign countries is very strict. If you lose a 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 provide money, there will be no artificial obstacles.

After hearing this, Chen Qi nodded slightly 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.”

 Nimura Kaito didn’t believe his ears and asked in surprise:

“How is this possible? How come China has already conquered 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 thing, producing a CT requires many components. No company in the world produces 100% of all components in-house, and all components need to be purchased from outside. 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 incident happened in 1982, when China independently completed the manufacturing and research and development of the Great Wall 1st generation mainframe and the Dawn 1 supercomputer. China was far ahead of Japan and the United States in this supercomputer technology.

Then just to show off and demonstrate national strength, China naively took the Great Wall 2nd generation large 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 by borrowing information defrauded from the Chinese.

Japanese precision machining is indeed better than that of China, and the appearance is beautiful and 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 technology projects from China:

For example, integrated industrial automation projects, large-scale welding systems, fuel cell nanotechnology of the Dahua 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 until his death (including the Yunnan Baiyao Pharmaceutical Factory after the founding of the People's Republic of China...)

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

Fortresses were conquered from within.
