Title: Shingo Koyama: Power Control and Wireless Power Feeding Inventions.

Introduction

Shingo Koyama is an inventor associated with Osaka, Japan, and Tsubakimoto Chain Company. His patent work includes technologies for controlling power systems and improving the safety and reliability of power feeding equipment. He is credited with 2 patents.

Latest Patents

Koyama’s patent “Power control device” describes a system designed to begin self-sustaining operation only after specified safety conditions are confirmed. The device checks for voltage and current and verifies that the main breaker is open before connecting an inverter to loads. If power flow or a closed-breaker signal is detected during self-sustaining operation, the device disconnects the inverter from the power system and stops that operation.

His patent “Power feeding apparatus, transporter and transport system” concerns a power feeding apparatus with pickup coils, a rectifier circuit, relays, and a protective switching control circuit. The circuit controls the relays according to voltage at the pickup coils. The design aims to prevent damaging overcurrent and overvoltage, indicate abnormalities, and support remote control of the power supply.

Career Highlights

Koyama’s listed inventions address practical challenges in power conversion and delivery. One focuses on safely transitioning between grid-connected and self-sustaining operation, while the other emphasizes protection and control in a power feeding system.

Collaborations

Koyama’s listed coworkers include Makoto Uehira and Satoshi Takashige. His company affiliation is Tsubakimoto Chain Company.

Conclusion

Shingo Koyama’s patent portfolio reflects work on safer power control and more resilient power feeding, with applications spanning electrical systems and transport-related equipment.
