Countercurrent 1982

Chapter 136 Development of Audio
While Duan Yun was busy working on the new workshop in the village these days, the technical department of the factory and the technicians in each workshop were busy.

Right now, there is only one week of preparation time left for the technical transformation competition at the end of the month. The high bonuses and the nomination of model workers stimulate the nerves of these technical workers all the time.

Especially for many technicians who have just entered the factory, they are young and energetic. They have just graduated from school and have no other state-owned enterprises. The environment of overstaffed people has sharpened their edges and corners. Their enthusiasm was greatly aroused, so that in the past two weeks, working overtime and drawing has become the norm. Even during the lunch break and meal time, there are still many young technicians fooling around in the drawing room. It is a very rare professional behavior.

In addition to these new recruits who want to stand out, such a high bonus has also attracted the hearts of many veteran technicians in the factory.

In particular, the issue of housing distribution involved in the selection of model workers has touched the workers whose families have poor housing conditions.

However, although the veteran technicians in these factories have long working experience, high operating skills, and a certain understanding of equipment, it is basically impossible for them to engage in Duan Yun's level of automated technical transformation.

Even compared with the technicians who just entered the factory, the gap between these old technicians and their mechanical modification technology is not small.

Therefore, for these old technicians in the factory, the only technical improvement results that can be made are very small. Some have slightly modified the fixture, and some have made some small tools that are convenient for picking materials. Disassemble the shell of the machine tool, so in general, it is just a small technical improvement with a very low technical level that cannot be put on the table, and it is not competitive at all.

Although the factory’s technological transformation competition this time did not specify the content of the technical transformation, Duan Yun’s modification of the old lathe last time has become a model of technological transformation in the factory, and the modification of the lathe itself is also the most direct way to improve production efficiency, so almost All technicians and technicians regard the modification of the new lathe as the highlight of the competition.

For more than a week, some technicians have sent the drawings of the technical transformation plan to the factory database in advance for storage and file registration. On the one hand, this is the requirement of this technical transformation competition, and it is also to prevent Imitation and plagiarism among colleagues.

In order to ensure the fairness of this technological transformation competition, the factory committee formulated the drawings and stored them in the archives. At the same time, the contestants can also go to the workshops and workshop directors to say hello, and arrange some workers to help process various workpieces for technical transformation.

The Red Star Gear Factory held this technological transformation competition with such great fanfare this time. Apart from the struggle of the director and secretary, there is also a very important point that the leaders of the factory have been overwhelmed by the problem of solving the housing problems of the employees. Now, after the higher-level license of the dual-track price system is obtained, it is urgent to increase production capacity on the basis of existing equipment, and Duan Yun's last automatic lathe modification has given the factory leaders a taste of the sweetness of technical transformation, so this time the entire factory The technological transformation competition is also very important.

However, Duan Yun, the award-winning 'popular figure' of this technological transformation competition, put his mind on other aspects after preparing the artifacts of the technological transformation competition in advance.

Now Duan Yun has become the leader of the night shift, and Huang Haitao, the leader of the night shift, is also quite polite to him.

Huang Haitao is also a good person. He has already seen that since Gao Lei left, almost all the apprentices in the third team have looked up to Duan Yun, and compared to Gao Lei who was the boss of the factory, Duan Yun now has a big secretary. Backing, so now Huang Haitao is more polite to Duan Yun than when he was facing Gao Lei.

Except that there is no work to be done on the night shift, and when Duan Yun is sleepy and tired, he can go directly to sleep on the bench in the cabin next to the control room. In order to please Duan Yun, Huang Haitao even left him a key. When he was about to take over the shift in the morning He also knocked on the door to remind him.

At this level, Duan Yun can be regarded as the "privileged class" among the workers in the factory.

Of course, in return, Duan Yun also gave Huang Haitao enough face. Apart from letting Cui Linleizi and his gang of apprentices try their best to cooperate with Huang Haitao's night shift work, he often stuffed him with a box of "big front door" to maintain a good relationship between the two of them. personal friendship.

The night shift has the opportunity to catch up on sleep, and Duan Yun has much more energy after returning home from get off work than before. Sometimes, he doesn't even need to catch up on sleep for a long time, and goes to work in the small room he rented.

Although Duan Yun is now mainly engaged in the antenna business, after setting up a small workshop in the village, his vision is set in a longer-term future.

Antennas alone are of course far from enough for Duan Yun to survive for a lifetime, so he must continue to develop new products with higher commercial value.

The idea of ​​starting a business with Duan Yun is to produce, trial-manufacture and research and development at the same time.

Seeing the tape recorder Gao Lei left for himself, Duan Yun suddenly had the idea of ​​making audio equipment.

Like TVs, bicycles, refrigerators and watches, tape recorders are also very popular home appliances in this era.

Of course, with the current equipment in Duan Yun's small workshop, it is impossible to make a finished tape recorder, but it is still possible to make related audio equipment.

As for the principle and technology of speaker equipment, it is not difficult for Duan Yun, a Ph.

After spending two whole afternoons, Duan Yun finally designed a set of blueprints for the two-channel speaker circuit board.

Afterwards, Duan Yun handed over the drawn drawings to Cui Lin who was going to work in Majunying Village in the afternoon.

Now that there are more and more people, Duan Yun doesn't need to do everything by himself. He only needs to draw the blueprints, and other people can handle the rest of the processing and welding of the circuit boards.

Lei Zi had studied electrician when he was in technical school, and he also used electric soldering iron to solder electronic components, so now he is mainly responsible for helping Duan Yun solder circuit boards in the small room of the factory.

In this case, Duan Yun only needs to devote himself to the design work.

Before dinner at night, Duan Yun's drawings became finished products and were handed over to him.

Duan Yun removed the speaker on one side from Gao Lei's recorder and connected it to the circuit board for a simple test, and the effect was not bad.

But for this mediocre electronic product, Duan Yun does not have any sense of accomplishment. His next step is to optimize the speaker equipment, determined to make an impressive audio equipment...
