Countercurrent 1982

Chapter 27 Anti-piracy Technology

"Thank you secretary!"

"Okay, if there is nothing else..." Zhao Dongsheng planned to order the eviction.

"Secretary, there is one more thing I want to tell you..." Duan Yun obviously did not intend to leave immediately.

"Say."

"That's right. Recently, Master Han and I studied together, and wanted to make some simple technical transformations on the old lathe we are using..." Duan Yun paused, and then said: "In this case, it can be improved a little bit. Work efficiency and quality.”

Duan Yun deliberately described his previous fully automated modification of the lathe as an understatement, and also included Han Zhong.

He understood that if he directly told Zhao Dongsheng about the automatic modification of the lathe, then Zhao Dongsheng would definitely not agree, and he might criticize the previous paragraph.

After all, a lathe is an important corporate asset. Once Zhao Dongsheng agrees to refit and the machine fails and the machine is damaged or scrapped, even if it is an old machine that is about to be scrapped, Zhao Dongsheng himself will be held responsible, so not only Zhao Dongsheng, but also others It is impossible for any leader, including factories, to make such a guarantee easily.

But if Duan Yun described the automatic modification of his lathe as a small technical improvement, then Zhao Dongsheng would probably not care. After all, many old workers in the factory would also process some special gadgets by themselves for the convenience of their work. Making improvised jigs and the like, this is a very common thing and not worth mentioning.

"This is a good thing." Zhao Dongsheng smiled when he heard the words. He obviously did not find Duan Yun's remarks to be trapped. In addition, based on his understanding of Han Zhong's personality, he did not believe that he would condone Duan Yun's actions. A reliable thing came, so he said: "It is a good thing to engage in technological innovation, and I fully support you! But you need to learn more and master more theories and technologies in the future. You can communicate more with your workshop technicians and masters. , must not waste materials recklessly."

"I will definitely learn more in the future." Duan Yun was waiting for these words, and then nodded again and again.

"If you have nothing to do, go back and rest early. It's hard work just after the night shift."

"Then I won't disturb your work, secretary." After Duan Yun finished speaking, he got up and left Zhao Dongsheng's office.

Seeing Duan Yun leave, Zhao Dongsheng's face suddenly sank.

Picking up the application for joining the party written by Duan Yun on the table, Zhao Dongsheng glanced at the trash can beside him and seemed to feel a little out of place. Then, after placing the drawer next to the bottom of the pile of manuscripts, he shook his head and said to himself:
"Young people these days, what is going on in their minds every day..."

……

After Duan Yun left the office building, he felt relieved.

He didn't expect the secretary to find his worth right away, but the relationship needs to be cultivated a little bit, especially if an ordinary worker wants to establish a relationship with the leader, which is not an easy task in itself.

When he came home from get off work, Duan Yun ate and slept in the morning as usual. After lunch, he took the radio brought by his sister to his rental house.

The number of radios I got today was a little less than a few days ago, only fourteen.

Although there are still 80 yuan in the account, Duan Yun also knows that this business can't last long.

At four o'clock in the afternoon, after everyone finished work, they took out the antenna drawings designed last night and made some revisions again.

Afterwards, Duan Yun left the rental house and went to the hardware store in the factory area.

For less than two yuan, Duan Yun bought an aluminum tube, a few meters of feeder, thin copper wire and a box of small screws.

In addition, Duan Yun also bought some tools for making antennas.

Vise, screwdriver, file are all must-haves.

And the hand drill.

Originally, Duan Yun wanted to go into the city to buy it in a department store, but was worried that if it broke, he would have to go to the city to repair it, so he simply bought it directly from the factory hardware store.

The 6A single-phase serial electric hand drill produced by the HHHT power tool factory sold here is not too expensive, only five yuan and fifty cents.

With these things, Duan Yun returned to the rental house.

The antenna structure modified by Duan Yun is not complicated, and its appearance is similar to the Yagi antenna that is popular in the south.

Duan Yun first cut 6 copper rods with a vise, and made punch marks on the corresponding positions of the aluminum square tube.

Use a Φ3mm drill bit, and use a bench drill to drill through the square tube on the 5 holes of the square tube, so that the copper electrode can just be inserted into the cross bar.

In order to facilitate adjustment and disassembly, a hole can be drilled on the top of the vibrator, a nut can be welded, and the screw can be tightened to fix the vibrator.

Then Duan Yun took a few galvanized aluminum sheets to fix the vibrators at the front and back ends with screws, and the whole antenna suddenly became much more beautiful.

This Yagi antenna made by Duan Yun is not just a simple imitation, but a technology that he improved together with his lecturers and classmates in the laboratory in his previous life.

During the period, Yunhe and his classmates adjusted the spacing and replaced the length of the active oscillator, reflector, and director, so that the electromagnetic parameters of the antenna reached an ideal state.

This is definitely a core technical parameter.

It is said that there has been no patent in the past two years. The domestic patent technology was passed in 1984 and implemented in 1985. If Duan Yun's antenna is imitated, he will not be able to take legal action at all.

Therefore, Duan Yun must have its own core technology that cannot be easily copied.

The first is the appearance design of the antenna. Since this improved version of the Yagi antenna of Duan Yun has been repeatedly tested and adjusted, the distances and reflection angles of several oscillators are strictly distances and angles. The ability will be greatly reduced, and only Duan Yun knows the knowledge in it.

The other is the antenna amplifier designed by Duan Yun for this antenna.

The so-called antenna amplifier is actually an electronic component used to enhance the weaker TV signal received and improve the quality of information reception.

If the appearance of the antenna is easy to be copied and imitated, it will be quite difficult to copy the antenna amplifier designed by Duan Yun.

In order to prevent being 'piracy', Duan Yun decided to adopt some of the practices of his previous counterparts, that is, to use a double-layered circuit board.

This method is also very simple, that is, after the circuit boards are stacked into multiple layers, the real circuit boards are glued with 502 glue by the method of buried holes. In this case, those who want to copy the circuit boards cannot accurately Judge the layout of the real board, and if you try to disassemble the multi-layer board, you will seriously damage the real board.

There is also a short-circuit device installed in the real circuit. Once disassembled, it will cause self-destruction, which is also an important means to effectively prevent piracy.

Although adding these anti-piracy parts will increase the cost of Duan Yun's antenna production, in order to maintain the monopoly of this advanced antenna business, it is obviously very necessary to do so!
