78: Bringing his wife and children to Harbin Institute of Technology

"However, the local quality inspection results should also be taken into account when purchasing civilian products."

"If your two families go to court, it will be difficult for us to handle things while we are caught in the middle."

Ye Bingwen did not respond to this question.

He turned to look at Engineer Zhang.

"Mr. Zhang, what model of oscilloscope did you use when you measured the vibration at my factory last time?"

Engineer Zhang was stunned for a moment.

"SBT-5, an old model."

"What is the bandwidth?"

"Seven megahertz".

Ye Bingwen nodded.

"Seven megabytes is enough, but the resolution is insufficient when measuring high-frequency components."

"In the vibration spectrum of my motor, there is a small peak around three kilohertz."

"With an amplitude of only 0.005 millimeters, the SBT-5 may not be able to see it clearly."

Zhang Gong's expression changed.

"Have you measured the spectrum?"

"I've tested it. I used a spectrum analyzer circuit that I built myself."

Ye Bingwen took out another piece of paper from his bag and handed it to Engineer Zhang.

Engineer Zhang took the spectrum and looked at it for a full half minute.

What kind of sensor are you using?

"I made a charge amplifier for the piezoelectric accelerometer."

Engineer Zhang raised his head, his eyes shining.

"Director Ye, where did you learn all this?"

"Read books. Figure it out yourself."

Ye Bingwen's answer was brief.

Although Director Fang didn't quite understand terms like spectrum and bandwidth, he understood Zhang's expression—it was a meeting of experts.

"Mr. Zhang, how's Xiao Ye's skill level?"

Engineer Zhang placed the spectrum diagram on the table and thought for a moment.

"Director Fang, I have worked in the military industry for fifteen years and have met many technicians who work with electrical machinery."

"He's the first person to be able to build a circuit and measure the spectrum without professional equipment."

He glanced at Ye Bingwen again.

"Moreover, the 3,000 Hz peak he mentioned is completely undetectable unless the spectrum has been measured."

"This shows that his research on motor vibration has reached the level of frequency analysis."

"At this level, there are very few people in the province who can talk to him."

Director Fang remained silent for a while.

"Xiao Ye, you didn't come to see me today just to show me this picture, did you?"

Ye Bingwen raised his head.

"Director Fang, those people from the Provincial Department of Industry are targeting me, not because my motors are substandard, but because I've taken away their profits."

"They're withholding my equipment approval, suppressing my quality inspection reports, and they might even cut off your order next."

"I've come today to say something to you."

Director Fang didn't respond, waiting for him to continue.

"There are more than one factory in the province that can accept your order than I am, but the technical requirements for your batch of military products are different."

"It was decided by Director Fang and me. You know better than I whether other factories in the province can do it."

Director Fang's expression changed slightly.

Are you telling me you're irreplaceable?

"I'm not telling you that."

Ye Bingwen's tone was very calm.

"It's a reminder. Because someone might tell you, 'You can do the same job at another factory.'"

"If you listen to them and transfer the order, you'll find that the work they produce is substandard."

"What is wasted is your time, and what is lost is the equipment progress of the troops."

"My indispensability is not something I say, but something my machine tool says."

The office was silent for a few seconds.

Engineer Zhang coughed beside him.

"Director Fang, Factory Director Ye is right. Those three indicators are indeed difficult for other factories in the province to meet simultaneously."

Director Fang stared at Ye Bingwen for a long time.

"Xiao Ye, you've got some nerve. Talking to me like that."

"I'm telling the truth."

Director Fang suddenly smiled.

"Okay. I like to hear the truth."

He took a document out of the drawer.

"Take a look at this."

Ye Bingwen looked down and saw that it was a purchase intention document.

The quantity to be purchased below is not the two hundred units mentioned before, but five hundred units.

"Five hundred units?"

"Yes. The first batch of two hundred units is already in your factory, and the second batch of three hundred units was originally scheduled to be contracted next month."

Director Fang paused for a moment.

"But after the provincial industrial department's report came out, someone from above contacted me and told me to 'reconsider' the supplier."

Ye Bingwen's heart sank.

"Who made the call?"

"You don't need to know that. All you need to know is that someone is using administrative means to pressure me."

Director Fang took the document back.

"I can stall for a while, but not for too long. You'll have to resolve the issue with that quality inspection report yourself."

"Otherwise, even if I wanted to give you the order, it wouldn't be possible to do so through the proper procedures."

Ye Bingwen stood up.

"Director Fang, I'm not here today to ask you to reserve the order for me."

"Then what are you doing here?"

"I need something from you."

"What is it?"

Ye Bingwen took out Hu Guangzhi's technical evaluation report and Professor Zhao's departmental report from his bag and placed them on the table.

"I would like to send these two reports jointly to the Provincial Defense Industry Office on your behalf."

"A technical review of the quality inspection report from the Provincial Department of Industry is required."

"You don't need to take sides, you just need to prove one fact—my motor meets military testing standards."

Director Fang looked at the two reports.

"You young man, you've planned every step of the way."

"It won't do. The opponent has already thrown a punch, I have to fight back."

Director Fang picked up the phone on the table.

"Xiao Ye, keep a copy of your technical analysis report with me. I'll have someone submit it to the Provincial Defense Industry Office for you."

"But there's one condition—I can't guarantee whether this will work out."

"It's fine as long as you're willing to deliver it."

Ye Bingwen kept one copy of each of the materials he brought and packed up the rest.

"Director Fang, Engineer Zhang, sorry to bother you."

Director Fang waved his hand.

As Ye Bingwen reached the door, Director Fang's voice came from behind him.

"Xiao Ye, did you build your own spectrum measurement system?"

Ye Bingwen turned around.

"Yes. It uses a transistor; I drew the circuit diagram myself."

"Give me a copy of the circuit diagram when you have time. Our equipment department also needs this kind of small device."

"Okay. I'll have someone deliver it tomorrow."

It was already noon when I came out of the provincial military compound.

Ye Bingwen didn't go into the factory, but instead turned onto the road leading to the Provincial Machinery Research Institute.

He was going to see someone.

It wasn't Hu Guangzhi, but someone Hu Guangzhi had mentioned to him—the current chief engineer of the Provincial Mechanical Research Institute, surnamed Meng.

Ye Bingwen originally didn't want to go to Chief Engineer Meng so soon, but now the report from the Provincial Department of Industry has been released.

The pressure on Director Fang has also increased; he needs more technical support.

It's not about asking for help, it's about letting those with technical knowledge see the truth.

Ye Bingwen parked his bicycle downstairs and went through the gate.

The old man in the gatehouse stopped him.

"Who should I look for?"

"Chief Engineer Meng. I was introduced by Engineer Hu Guangzhi."

The old man picked up the phone and dialed a short number.

"Mr. Meng, someone downstairs is looking for you. They said they were referred by Engineer Hu... Okay."

After hanging up the phone, the old man gestured towards the stairs with his lip.

"The third floor, the innermost room."
