Chapter 531: Special-shaped gears

Now just in April, Liu Lang is going to stay at home for a month, during this time in addition to being with relatives, learning naturally can not be left behind, came back from the United States to buy a lot of books, are about mechanical professional books, although these books do not involve many technical secrets, but for the Western industrial system have a very detailed explanation.

In addition, there are several college textbooks bought from Stanford University Press are very valuable, many details in the book in the construction machinery have opened Liu Lang's eyes, the industrial system of the United States is really very perfect, the types are several times more than the domestic ones, each branch is to establish its own standardization, dozens of classifications combined together, to build a complete industrial system.

Liu Lang copied a set of these books for Xiong Huaizhi, but now it cannot be realized in China, because many industrial branch countries do not have the conditions to set up, and can only be used as teaching materials, so that the next generation of national industrial talents can build their own industrial base according to these systems.

In addition to learning some industrial knowledge from the West, Liu Lang's most important thing is to complete the thesis, which is entitled "How to Improve the Strength of Fire Ladders." ”

It is now eighty-six years, even if the maximum extension length of the American fire ladder is only about 25 meters, and Liu Lang's previous life, the fire ladder can reach a maximum of 100 meters, which is a veritable ladder, of course, the ladder material is high-strength carbon fiber, the weight is much lighter than aluminum, and the power is also hydraulic, strong enough to push dozens of tons of weight.

This era is obviously not good, carbon fiber this material will not appear in the laboratory for more than ten years, and the hydraulic power source is very cumbersome, as long as it will be equipped with large crane equipment, the fire ladder is completely made of aluminum, relying on a section of assembly to extend out, each section is about four or five meters long, at most there can only be five or six sections, and then there is a possibility of intermediate fracture.

The reason why it breaks is that the screw connection between each section becomes overwhelmed with the growth of the torque, even the toughest steel cannot withstand the strength of the torque, if it is long enough, then Archimedes can lift the whole earth alone, how big is this moment?

In this era, the maximum elongation distance of the fire ladder is only twenty-five or six meters, but Liu Lang's design can raise this length to about thirty meters, an extra five or six meters in length, which does not seem to be long, but this is the height of a one-story building.

Liu Lang designed a kind of special-shaped gear, what is called a special-shaped gear? As the name suggests, the shape of this kind of gear is not a standardized shape.

The gear designed by Liu Lang suddenly looks like a big coconut, but in fact this "coconut" is composed of five gears in the shape of leaves, and when the five gears turn, this "coconut" becomes a very strange shape, and the teeth and claws are very "ferocious".

It seems simple, but if you open this "coconut", you will find that each gear is as precisely combined as a watch, and after each ladder is firmly clamped by this gear, the torque power will be borne by these five gears, and the strength is more than doubled.

Of course, the design of this gear is only the beginning of this paper, the text uses mechanical formulas to write out in detail the support force provided by the gear and the torque that it may withstand when working, whether anyone who reads this paper, in addition to marveling at the unimaginable of this gear, will also 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 fanciful image, it can only be used as an ornament if it is useless.

This paper is not long, most of them are mathematical and physical formulas, and the theories involved are basic mechanical knowledge, but the argument is clear, no one will refute it, it can be said that with this paper, you can manufacture the latest fire ladder, which can be put into use after testing.

Liu Lang plans to patent this unique design first when he goes to the United States next time, maybe he will not charge royalties, but let Americans know that this life-saving device is made by Chinese.

At the end of April, Professor Zhou Ming made a call to Liu Lang, the wafer production line has been successfully transformed, and the latest generation of chips can be manufactured, the new generation of chips has image processing functions, which is called Photoshop1 program by Wanhe, this Photoshop1 picture processing program can not be compared with later generations, it can only have the function of identifying pictures, of course, now other companies in the United States also have some corresponding image processing programs, but compared with this program, its resolution is two orders of magnitude worse, Photoshop1 image processing program can basically present the same effect as photos on the computer。

The production capacity of this chip is 200 pieces per month, and 100 chips have been manufactured, and these 100 chips have been shipped back to the United States, where they are being debugged, and once they are successfully commissioned, they will be put into the market immediately.

The success of chip manufacturing is gratifying, but Zhou Ming is still a little worried, not anything else, or the cost of chip manufacturing is a bit high, the cost of each chip has reached 1,000 yuan, this 1,000 yuan does not include artificial water and electricity bills or anything, it is purely the cost of high-purity semiconductor materials and equipment, according to a 200 chip calculation, that is, 200,000 yuan, 2.4 million yuan a year, can this money be earned?

"Professor Zhou, don't worry, don't say it's 2.4 million yuan, it's no problem if it's 24 million, the only thing I'm worried about now is that our SMIC production capacity is not enough, and the production capacity of more than 2,000 yuan a year is still much worse!"

Now VIE sells more than 20,000 computers every year, of course, computer sales is not the only business of VIE, VIE sells more printers and electronic office equipment every year, these equipment can be connected to VIE computers, and can also be used alone, this aspect of sales is the majority, and the annual shipments are more than hundreds of thousands.

Computer chips are all produced by Wanwan, and so on to the era of personal computers, the price of computers has dropped sharply, and the annual sales volume will definitely double, although your chips are good, but the production capacity will not affect profits, this is the problem that Liu Lang is worried about, as for whether the question of whether to make money is purely groundless, he believes that as long as the computer with this chip appears on the market, it will immediately cause shock, in this era, every tool that can make people convenient will inevitably become the object of people's pursuit.

Liu Lang's enlightenment reassured Zhou Ming, in fact, it is not only Zhou Ming, but also a higher level, for example, Bai Weiren and even those leaders at the national level are also paying attention to it, because Liu Lang once told them last year that just this year, the world will set off a big wave, and the chip industry, which has not been obvious, will become the mainstream industry of the world, accompanied by the arrival of an unstoppable era, it is already May, why has this wave not yet appeared? Is Liu Lang's prediction biased?

Of course, even if there is a deviation, the country will not say how Liu Lang is, at least China has made great progress in the chip industry, but it has only lost hundreds of millions of yuan, compared to Liu Lang's other achievements, this loss is insignificant, but if so, the future of SMIC is not easy to say, maybe the country will not be as large-scale support as in the past year.
