"The technical difficulty of starting a single motor dual card recorder is indeed very high, but it is not impossible to achieve ......" Duan Yun paused, and then said: "First of all, you need a very high-quality motor, strong power, good stability, in addition, you also need to design a new integrated circuit and a new electronic private service control mechanism, which requires additional circuit settings, but in general, if you can use a motor drive, you can greatly reduce the production cost......"

"The tape recorder motor is indeed costly, if you can use one less, of course, you can save a lot of costs, but the question is where do we purchase this high-quality motor?" asked another professor next to him.

"In fact, the production line we imported from Japan this time can produce high-quality motor ......," Duan Yun said.

"But I see that the motor production equipment of this imported production line is very general, and the production efficiency of two equipment is very slow, which is not as good as similar products in China. Zhao Xuewu was all said by him at this time.

"Looking for a master, you don't really think that the little devils will sell their complete production line to us, right?" Duan Yun said with a smile when he heard this.

"What do you mean?" Zhao Xuewu was stunned for a moment.

"In fact, the motor production equipment on this production line is castrated, and it is impossible for small Japan to hand over the best technology to us, but in order to facilitate the sale, he must maintain the integrity of the entire production line, and under the premise that the best production equipment can not be sold to other manufacturers, they can only disassemble the key circuit equipment and replace it with the old and eliminated circuit plates, so that the machine can only play half or even lower than the original performance......" As Duan Yun spoke, he picked up the file bag in front of him and pulled out a few design drawings from it.

"And this kind of thing!?" Hearing this, Zhao Xuewu seemed to react to something.

“...... I don't know Master Zhao, have you seen the AR-3 automatic winding machine on the production line? Honjo Co., Ltd. provided us with a winding machine with 4 rotating winding shuttles, but in actual operation, only two winding shuttle heads can be used, the other two of our shuttle heads are completely like decorations, I also opened the circuit board of this machine to see, and found that there are many traces of re-soldering of the electronic originals on it, and there are two places marked as integrated circuits are empty, which is obviously disassembled......" Duan Yun picked up one of the circuit drawings and put it in front of everyone and tapped it with his fingers, and then said: "And you can take a closer look at this drawing, the circuit diagram on it is obviously different from the current circuit board, although the electronic components are basically the same, but many circuits on the circuit board are obviously redundant, and from the paper, this paper is a little yellow, and it is not drawn at the same time as other product drawings......

When Duan Yun said this, everyone present was taken aback, and after carefully comparing these drawings, they soon found that there was indeed something greasy in them.

"In fact, Honjo Co., Ltd. their production of tape recorder motor in the Japanese market share is still very high, the motor rotor iron sheet stamping machine is used in high-speed punching, high efficiency, high precision, motor custom shell and cover using multi-power continuous die molding, the material has been surface coated with tape and tape, multi-station stamping machine, each punch out of a part, but the surface plating is not destroyed, stamped out of the parts do not need to be electroplated, which can effectively ensure the consistency of the size, easy to assemble ......" Duan Yun began to carefully analyze the advantages of this imported production line, only to hear him continue: " In addition to these equipment, there are many other processes in the country are very leading, the commutator and the shaft of the use of slip fit, the commutator surface finish is obtained on a special commutator grinding machine after two abrasive belt grinding, grinding in the armor grinding vacuuming, cleaning and drying, are automatic, this grinding method not only improves the surface finish of the commutator, but also improves the concentricity of the commutator and the shaft, which is very advanced technology......"

Duan Yun was very excited when he said this, because what he was talking about now had already involved the advanced core technology of the current domestic tape recorder, and if the production line could be reasonably modified this time, he would have a good chance to reduce the production cost of the dual-card tape recorder and achieve corner overtaking in the domestic market.

After hearing Duan Yun's explanation, several other technicians present also became more and more excited, and at the same time, they were also surprised by Duan Yun's keen observation and technical attainments, so that top domestic electronics experts such as Zhao Xuewu and Yang Xiuchun also felt a little ashamed.

"Manager Duan, you are too powerful, I am not a sycophant, you are really powerful, I have been staying in the workshop every day to study this production line for the past few days, and the result is not as thorough as your observation, it is really terrifying......" After Duan Yun explained, Zhao Xuewu said with some emotion.

"Manager Duan, did you really teach yourself electronic technology before?" Yang Xiuchun couldn't help but ask.

"I only found out about the equipment problem of this production line occasionally, and I was just lucky. Duan Yun replied lightly, and continued: " Our task now is to find out the working principle of this set of motor production equipment, and then redesign the circuit, so that this set of equipment to play his original production capacity, followed by to learn from the new product design ideas of domestic and foreign counterparts, on this basis, and strive to design a low-cost single motor drive dual card recorder, this is the first important task after the establishment of our research institute, I hope everyone can work together to make new products in the shortest possible time, I believe that everyone has the strength in this regard!"

"That's good!" As soon as Duan Yun's words fell, Zhao Xuewu took the lead and slapped his face, and the conference room immediately burst into warm applause.

And Cheng Qingyan, who had been standing next to her without saying a word, looked at her husband with a little surprise and relief in her eyes at this time.

"In the future, I will provide sufficient funds for our institute, I have some foreign exchange in my hand, I can buy some similar products abroad for everyone to disassemble and analyze, and if you have any needs, you can directly contact me and my wife, or Director Li of the Guangzhou office, you can help you solve it." Duan Yun said.

"Manager Duan, the current manpower of our research institute is still ......a little small," Zhao Xuewu said suddenly at this time.

"On the issue of personnel in the institute, I also told Director Li of our Guangdong office yesterday, he has now issued a recruitment notice in Guangzhou City, and is ready to hire more than 10 highly educated technical talents to join our electronics factory, so you don't have to worry about the problem of insufficient manpower. Duan Yun replied with a smile.
