Title: Innovations by Kouichi Machida in Waste Heat Power Generation

Introduction

Kouichi Machida is a notable inventor based in Tokyo, Japan, recognized for his contributions to the field of waste heat power generation. With a total of three patents to his name, Machida has developed innovative devices that harness waste heat energy to generate electricity efficiently.

Latest Patents

Among his latest patents is a waste heat power generation device. This device features an evaporator that recovers waste heat energy to evaporate a working medium. It includes an expansion turbine generator that generates electric power with the working medium supplied from the evaporator. Additionally, a condenser condenses the working medium discharged from the expansion turbine generator, while a pump feeds the condensed working medium back toward the evaporator. A measuring device is also incorporated to measure the amount of power generated by the expansion turbine generator per unit time, along with a control device that regulates the pump's operation based on the measurement results.

Another significant patent is the waste heat power generator, which consists of an evaporator that produces steam from a working medium. This generator includes a power-generating device that generates electric power by expanding the steam. A condenser condenses the steam after it has passed through the power-generating device, and a pump sends the condensed working medium back to the evaporator. This generator may also feature a valve device to selectively supply a cooling medium to the power-generating device, controlled by a controller based on the temperature of the power-generating device.
