Siheyuan: Starting from a fitter

Chapter 144 One stone stirs up a thousand waves
Li Guocheng took out a patent application report from his bag, which mainly discussed CMOS technology and practical applications, and gave examples. Of course, this example was modeled in Li Guocheng's mind and then drawn by hand.

It describes the 5 basic logic gates, AND gate, NOT gate, OR gate, NOR gate and XOR gate, and uses mathematics to deduce that all logic can be composed of these 5 logic gates.

In order to increase credibility, a photo is provided of Li Guocheng practicing casually on the chip.

The report basically covers all digital circuit applications in the future, and the number of patents reaches 12. Not because the country is reluctant to spend money, Li Guocheng will write more patents.Sorry, in the future digital circuits will be written first by China.

"Grandpa, Dad, this is very important. We must do everything we can to complete the patent application as soon as possible, and it must be a global application. In the future, our country will rely on these patents to exchange patents with the West and reduce the price of our equipment." .

Li Guocheng specifically discussed the importance of patents when he submitted his patent application.In order to avoid suspicion, this report was submitted directly to Mr. Zhao without a signature.

Li Guocheng also knew that these patents might not necessarily bring the West into submission, but at least they could act as a mutual restraint.Everyone knows: truth lies only within the range of a cannon.

"Grandpa, Dad, there is one more thing. Tomorrow's interview is recommended to focus on the laboratory as a whole, and don't highlight individuals."

"Haha, I knew you would say that. Don't worry, they have been informed." Dad Zhao laughed.

After hearing the exact news, Li Guocheng was finally relieved.

"As you know, we have just designed the first-generation CPU, but it actually only has computing functions. The functions are relatively simple. Next, the focus of our laboratory is to design a more powerful CPU.

It can complete the following four main functions:

1. Scientific computing, using the high-speed computing, large storage capacity and continuous computing capabilities of computers, can realize various scientific computing problems that cannot be solved manually;

2. Data processing, collection, storage, processing, transformation and transmission of data;

3. Assisted design refers to using computers to help engineering and technical personnel carry out design work;
4. Process control, using computers as control components to control a single piece of equipment or the entire production process.

To accomplish the above functions, it is necessary to design a powerful computer language and control system."

The two of them seemed to understand, but they didn't fully understand it, because they were still stuck in mechanical equipment, and their understanding of electronic equipment was only mathematical calculations.

Li Guocheng did not insist on it. After the specific application research is completed, they will understand the power of electronic equipment.

Zhao Ting was brought back by Li Guocheng on his bicycle.After arriving home, Li Guocheng washed Zhao Ting's feet for the first time. Although he was not moved to tears, his eyes became softer than ever before.

When he arrived at the laboratory the next day, Li Guocheng hid in the semiconductor laboratory and never appeared in public or in the dust-free workshop.

It has been noisy outside since 8 o'clock in the morning. The reporter, accompanied by Li Huaide, visited the dust-free workshop and stood in the post-production workshop to record everyone's busyness.

Wu Liankui became the real protagonist. He introduced the general functions of each device to everyone, and showed everyone the dedicated chip of the radio and the final product: Shuguang radio.

Everyone saw the small and beautiful radio, took photos and videos frequently, and asked about the price.

Li Huaide stepped forward, "Comrades, the specific price needs to be approved by the superior, and it is inconvenient to disclose it today."

Afterwards, exclusive interviews were conducted with Li Huaide and Wu Liankui respectively in the auditorium.The two of them talked based on everyone's consensus yesterday. They basically talked about the collective and repeatedly emphasized the power of the collective.

Specifically, the invention of each device was evenly distributed to everyone.At the same time, the inventions and creations of the machine tool team were promoted.

In short, everyone was very happy with today's interview, and the reporters also felt that it was very rewarding. All the materials were true and detailed. It was the most comfortable interview in recent times, and they were even more proud of the powerful science and technology of the motherland.

So after the reporters returned home, they worked overtime to write the article. With the help of thoughtful people, the press release of the steel rolling mill was rarely published in the newspapers the next morning, and the news clip was broadcast on Capital TV in the evening.

Taking the TV station as an example, it talked about 7 firsts.

The first domestic high-precision Shuguang II machine tool was finalized, with a processing accuracy of up to 0.05mm.

The first internationally leading photolithography machine with a photolithography accuracy of 12 microns.

The first internationally leading etching machine with an etching accuracy of 10 microns.

The first internationally leading chip consists of 7 silicon-based transistors.

The first internationally leading radio using an integrated chip radio.

The first internationally leading 2-inch monocrystalline silicon rod production line.

The first internationally leading dedicated chip production line with actual production capacity.

Anyway, just brag about how awesome you are.Finally, let’s take a close-up of the Shuguang radio. Behind the Shuguang radio is a common large radio.Comparing them together, the special appearance of Shuguang radio made the audience become fans immediately.

As the incident unfolded, everyone in China knew that there was a steel rolling mill in the capital, and there was a laboratory in the steel rolling mill. The laboratory was full of high technology, and the laboratory was full of great scientists.

Some young people who were preparing to get married immediately changed the "one ring" that turned three times and then beeped to Shuguang radios, and went to the nearest supply and marketing cooperative or department store to inquire about Shuguang radios.

The leaders of the steel rolling mill did not expect that Shuguang radio would become so popular and become popular even before it was launched on the market.

While arranging production, Li Huaide went to the ministry to apply for approval.The ministry also dealt with special matters, and within a week, the approval was given.

Of course, the casing of the radio is also molded, and the pattern is relatively simple and elegant.

The dust-free workshop started producing chips at full capacity from this day on.

After that, people came and went in the steel rolling mill, some were visiting and studying, some were waiting to pick up the goods with batch slips, and some were waiting to pick up the chip production line first.

Nowadays, there are several apprentices next to the semiconductor laboratory. Some of these people are transferred from various workshops, and a small part are college students or technical secondary school students who graduated in the past few years. They were transferred from some factories by the ministry.

Li Huaide was in pain and happiness as he was greeted and sent off at the steel rolling mill.In addition to being a tour guide in the dust-free workshop, Wu Liankui also participated in various lectures and occasionally participated in receiving some awards.

A month later, except for the people in the wafer preparation room who remained unchanged, Zhang Zhijing, Zhou Xiaojuan, Yan Jiefang, Hou Zhenhua and Hu Bing all returned to the semiconductor laboratory.
