It's just April now, and Liu Lang is planning to stay at home for a month. During this time, in addition to spending time with his relatives, he can't miss studying. He came back from the United States and bought a lot of books, all of which are professional books on machinery.
, although these books do not involve many technical secrets, they have very detailed explanations of the Western industrial system.
In addition, I bought several college textbooks from Stanford University Press, which are very valuable. Many details about engineering machinery in the book opened Liu Lang's eyes. The American industrial system is really very complete, and there are more types than in China.
Several times, each branch has established its own standardization, and dozens of classifications are combined to build a complete industrial system.
Liu Lang copied a set of these books for Xiong Huaizhi, but they are still not available in China because many industrial branch countries do not have the conditions to establish them, and they can only be used as teaching materials. Only the next generation of national industrial talents can follow these systems.
Build your own industrial base.
In addition to learning some Western industrial knowledge, Liu Lang's most important thing is to complete the thesis. The title of the thesis is "How to improve the strength of fire ladders."
It is now 1986. Even the maximum extension length of the American fire ladder is only about 25 meters. In Liu Lang's previous life, the fire ladder could reach a maximum of 100 meters. It was a real ladder. Of course, the ladder material
They are all made of high-strength carbon fiber, which is much lighter than aluminum, and the power is hydraulic, which is powerful enough to push dozens of tons of weight.
This era is obviously not good enough. It will take more than ten years for carbon fiber materials to appear in the laboratory. The hydraulic power source is very heavy and can only be equipped on large cranes. The fire ladder is entirely made of aluminum and relies on
It is assembled and stretched out section by section. Each section is about four or five meters long, and it can only have five or six sections at most. If it is longer, there is a possibility of breaking in the middle.
The reason why it breaks is that the screw connection between each section becomes overwhelmed as the torque increases. Even the toughest steel cannot withstand the strong torque. If it is long enough, then Archimedes
One person can lift the entire earth. How much torque is required?
In this era, the maximum extension distance of the fire ladder is only 256 meters, but Liu Lang's design can increase this length to about 30 meters. The extra length of 56 meters does not seem to be long, but it is
However, the height of one floor is enough to save many people in the event of a fire, and its meaning cannot be reflected in its length.
Liu Lang designed a special-shaped gear. What is a special-shaped gear? As the name suggests, the shape of this gear is not a standard shape.
The gear designed by Liu Lang suddenly looks like a big coconut, but in fact this "coconut" is composed of five leaf-shaped gears. When the five gears rotate, this "coconut" becomes a very big coconut.
It has a weird shape, and its teeth and claws are very "brutal".
It seems simple, but if you open this "coconut", you will find that each gear is combined together as precisely as a watch. After each ladder is firmly clamped by this gear, the torque force will be controlled by this gear.
Five gears share the responsibility, and the strength is more than doubled.
Of course, designing this kind of gear is only the beginning of this paper. The paper uses mechanical formulas to describe in detail the support force provided by the gear and the torque it may bear when working. No matter who reads this paper, they will marvel at it.
This kind of gear is beyond imagination, and you will be impressed by the detailed proof.
Science is like this. No matter how good your imagination is, you have to use scientific methods to argue. Even if you design a colorful image that has no use, it can only be used as a decoration.
This paper is not long. Most of it consists of mathematical and physical formulas. The theories involved are all basic mechanical knowledge, but the argument is clear and no one will refute it. It can be said that with this paper, you can create the latest fire-fighting equipment.
The ladder is fully ready for use after testing.
Liu Lang plans to apply for a patent for this unique design next time he goes to the United States. Maybe he will not charge a patent fee, but he will let Americans know that this life-saving device was made by the Chinese.
At the end of April, Professor Zhou Ming called Liu Lang. The wafer production line had been successfully transformed and could produce the latest generation of chips. The new generation of chips had image processing functions and was called the photoshop1 program by Wanhe. This photoshop1
Image processing programs and future generations
Of course, it cannot be compared. It can only have the function of identifying pictures. Of course, other companies in the United States now also have some corresponding image processing programs, but compared with this program, the resolution is two orders of magnitude different. The photoshop1 image processing program is basically
The same effect as the photo can be presented on the computer.
The production capacity of this kind of chip is two hundred pieces per month, and one hundred pieces have been manufactured. These one hundred chips have been shipped back to the United States and are being debugged. Once debugged successfully, they will be put into the market immediately.
The success of chip manufacturing is gratifying, but Zhou Ming is still a little worried. It is none other than that the cost of chip manufacturing is a bit high. The cost of each chip has reached a thousand yuan. This thousand yuan does not include labor, water and electricity bills.
The cost of purely high-purity semiconductor materials and equipment, calculated based on a 200-piece chip, is 200,000 yuan, or 2.4 million yuan a year. Can this money be earned back?
"Professor Zhou, don't worry, let alone 2.4 million yuan, even 24 million is no problem. The only thing I'm worried about now is that our SMIC production capacity is not enough. The production capacity of more than 2,000 yuan a year is still insufficient.
There are so many!”
Now Wanan Company sells more than 20,000 computers every year. Of course, computer sales are not Wanan Company’s only business. Wanan Company sells more printers and electronic office equipment every year. These equipment can be connected to Wanan computers.
At the same time, it can also be used alone. Sales in this area are the largest, with annual shipments exceeding hundreds of thousands.
All computer chips are produced by Wanwan. In the era of personal computers, the price of computers will drop significantly, and annual sales will definitely double. Although your chips are good, if the production capacity cannot increase, profits will be affected. This is
Liu Lang is worried about whether he can make money. He believes that as long as a computer equipped with this kind of chip appears on the market, it will immediately cause a shock. In this era, every kind of chip can make people become
Convenient tools will inevitably become popular objects.
Liu Lang's enlightenment made Zhou Ming feel relieved. In fact, it was not just Zhou Ming, but leaders at a higher level, such as Bai Weiren and even the national level, were also paying attention because Liu Lang told them last year.
This year, the world will set off a big wave. The chip industry, which has always been relatively obscure, will suddenly become the mainstream industry in the world. With it, the arrival of an unstoppable era will come. It is already May. Why?
This wave has not yet appeared? Is there something wrong with Liu Lang’s prediction?
Of course, even if there is a deviation, the country will not say anything about Liu Lang. At least China has made great progress in the chip industry, but it has only lost a few hundred million yuan. Compared with Liu Lang's other achievements, this loss
It's insignificant, but if that's the case, then it's hard to say what the future of SMIC is, and maybe the country won't support it on such a large scale as it has in the past year.
