Chapter 458: What do you want (2)

Didu did not know that the person in that department faxed Zhou Qingfeng a few pages of the list of needs, and the person who wrote this list was really unusual.
At first glance, the models and names of several tools and components were listed, but the listing was also very skillful, which fully tested Zhou Qingfeng's supply capacity.
For example, machine tools, high-speed steel is more common, and cemented carbide is upscale. Cubic boron nitride tools are expensive and not easily available.
As for ceramic tools, they are at the forefront of exploration in materials science today.
The latter electronic devices are more sophisticated, one item is higher than the other.
High-power thyristors are widely used in the industrial field, as well as in the military field. If Zhou Qingfeng can get it, it shows that he has some strength.
However, the MOS devices of gallium arsenide and gallium nitride are biased toward military use.
For example, the fighter's radar needs to launch as much power as possible in the smallest possible space, and the satellites are pursuing extreme performance under the extreme weight, all these things are needed.
Domestically, these two fields are still in their infancy, and the United States has already begun to apply them.
The famous Aegis air defense system uses gallium arsenide for its radar. Its later improved model even uses gallium nitride.
GaN is currently in a laboratory state, and its power density is an order of magnitude higher than that of gallium arsenide.
As for industrial control and high-speed a / d conversion chips, these are the core components of guided weapons, and they have extremely extensive uses in the industrial field.
Unlike civilian chips, which operate at room temperature, military chips must withstand severe temperature changes and vibrations, and they must work normally under strong electromagnetic interference.
If it is an aerospace chip, the computing performance does not need to be strong, but in addition to more stringent environmental adaptation requirements than military chips, it must also be able to withstand the strong radiation of cosmic rays.
This makes such chips very difficult to make.
For example, the US atmel company dedicated at697f processor for satellite. This is a product more than two decades later and can be exported. But the price of a chip is as high as seventy thousand dollars.
In addition, there are those that are not exported, and even the models are kept secret.
The output of military-leading chips is very low, with only a few hundred or thousands of masks at a time. Each production is also guarded by military personnel.
At the end of production, all mask data and chips and even scrap will be taken away. The fear is that someone secretly sells it.
If Zhou Qingfeng can really get high-end gadgets, he will be very important in the minds of the minu ministries.
Open e-commerce window, industrial waste section, machine tool category.
Different types of tools have their own applicable environments and cannot be replaced. However, if we really talk about the high-tech direction, then the carbide tool with cubic boron nitride coating is the first choice.
The hardness of boron nitride is second only to diamond, but its thermal stability is far better than diamond, and its cutting performance is extremely good. It is a tool that can be used to process high-performance steel.
Research on cubic boron nitride began in the 1960s in China, but the basic industry was weak and product stability was poor. This has led to stagnation of related research.
By the 1970s, aero-engines began to use iron-based superalloys, and ordinary tools could not even process this stuff. At home, it was anxious to think of cubic boron nitride.
In the 1980s, the situation was even worse. Automotive manufacturing, aerospace, and electronic technology all require high-performance knives, and China can only find ways to import them.
A knife costs hundreds or thousands of dollars, which makes people want to cry.
In the nineties, new materials and new processes emerged endlessly. Forcing rabbits to promote the progress of cubic boron nitride production technology through 'external technology exchange'.
But even 30 years later, the domestic tool industry has not reached its peak, and it is still at the bottom of the industry chain. The quality of the finished tools is not high, and they still rely on imports.
Zhou Qingfeng's fingers slammed, and two tons of used knives smashed on the handmade carpet in the living room of his mansion. Expensive Persian rugs are not decently shabby.
The alchemy workshop opened, and more than a dozen spirit slaves floated out to work as hard laborers. The scattered and used boron nitride knives were moved into the alchemy array for repair.
This includes a lot of things like drills, milling cutters, turning tools, planers, and so on. It took half a day just to move it.
The tool is done, Zhou Qingfeng feels like to do some cutting-edge stuff.
chip.
No top-class foreign-class processor can be found on the e-commerce platform. This thing was either launched into the sky or destroyed by supervision.
In fact, foreign military-grade chips are rare. They are either housed in missile shells for use on the battlefield or destroyed after storage expires.
Most of them that can be thrown away as trash are industrial grade.
For example, Zhou Qingfeng saw an ad585, a product of the US adi company. These chips come in different grades and have different working environments.
The s-class usage document indicates that the operating temperature is ‘negative fifty-five degrees to positive one hundred and twenty-five degrees’, which is by no means analog-to-digital conversion posted on the circuit board of toys.
Bought, bought, bought!
Zhou Qingfeng was about to start, and found that the minimum purchase amount was one ton. Ad585s can be packaged in fourteen pins, and a chip weighs only a few grams.
Really buying a ton was enough to bury him.
Buy something else.
Godson 1e and Godson 1f?
Alas ... these two chips are interesting!
This is a standard aerospace-grade general-purpose processor for spaceborne computers. The Beidou series uses it. This kind of CPU is a bit too strong at the moment.
You must know that the operating speed of the 486 is only 50 megabytes, and the Godson 1e and 1f have reached 200 megabytes.
Strangely, domestic high-end chips are sold unrestrictedly on the e-commerce level, but not foreign ones.
When it comes to military-grade 486, a story must be told.
In 2001, Gao Zhan, a Chinese female scholar with a green card in the United States, and her family of three were preparing to return to the United States and were arrested by Guo'an plain clothes at the Didu International Airport.
Later things can make a spy war movie.
After Gao Zhan was arrested, her husband was quickly released with his son. After returning to the United States, the father and son actively lobbied for human rights organizations, the media, and members of Congress to demand a ‘rescue’ vision.
The US media was uproaring and collective solidarity.
This incident has been going on for several months. Gao Zhan's husband, who originally had a green card, was naturalized on the US Fire Line. The oath ceremony even went to the Capitol.
A vote of senators and members of the House of Representatives gave a speech in support of Gao Zhan, asking the rabbit government to release her immediately.
On April 3 of that year, the US House of Representatives, the Immigration Group of the Judiciary Committee, and a senior Democratic Rep. Sheila Jackson Lee proposed a motion (Motion No. .1358).
The bill proposes to grant Gao Zhan exemption from citizenship, so that the Eagle Sauce government will appoint people to the Rabbit Government in the name of Gao Zhan being a Hawk Sauce citizen.
Do you think Eagle Sauce is shameless now? People have long been shameless.
But that's not all!
On April 5th, Virginia Republican senator George Allen joined the other 6 senators of the Democratic Republican Party to propose a similar motion in the Senate (motion number: s.702).
Both bills require the Minister of Justice of the Eagle Sauce to immediately grant Gao Zhan Eagle Sauce citizenship without going through the oath process. To put it plainly is to stir up shit.
By this time, things would be too much trouble.
As early as March, Vice-Premier Rabbit visited the Hawks home, and then President Bush and Secretary of State Powell disputed the matter.
But Gao Zhan is still a rabbit citizen, and it's about you.
Does your business end here? Patterns!
The next operation is dazzling.
On July 24, the rabbit procuratorate determined that Gao Zhan was engaged in spying activities in Taiwan, and the court sentenced her to 10 years in prison.
On July 25, a spokesperson for the State Department of Eagle Sauce stated that it would use every level of diplomacy to put pressure on rabbit didu to urge rabbits to release Gao Zhan for humanitarian reasons.
On July 26, a spokesman for the White House of Eagle Sauce stated that President Bush had talked with Rabbit III for the first time since taking office and discussed the high-level vision .
On the same day, Secretary of State Colin Powell paid a state visit to didu, and pressured the rabbit on this issue.
Everyone felt that the rabbit would definitely not give in. But the next thing is called the peak circuit.
On the 26th, Gao Zhan, who had just been sentenced, was allowed to seek medical treatment outside the country. She quickly fled to the Eagle Sauce family, received a heroic welcome, and delivered a famous speech at the airport.
President Bush is so proud of this that he feels that his own pressure has played a role. The Eagle Sauce media even cheered this is the victory of ‘Freedom and Democracy’.
but......
In 2003, Gao Zhan was arrested again for espionage. But this time she was arrested by Eagle sauce FBI.
A Virginia court alleges that Gao Zhan has been selling prohibited high-tech products to Rabbit's CLP14 since 1998.
These include dozens of military-grade 486 chips.
Gao Zhan and his husband were jailed for this.
This matter was vigorous but tiger-headed, and the face of Eagle Sauce was up and down, and he did not mention it later.
But the rabbit has broken a 'deep sea', so it looks like a big loss.
From this, we can see how important cutting-edge chips are.
But now, Zhou Qingfeng has more military-grade 486 chips, and even more advanced ones.
but......
No, no, it's only 91 years.
Can't get too high-level, change it to a low-end one, just fine.
