Title: Kenji Yashiro: Innovator in Power Supply and Communication Systems

Introduction

Kenji Yashiro is a prominent inventor based in Tokyo, Japan, known for his significant contributions to power supply control and communication systems. With a total of 13 patents to his name, Yashiro has made a lasting impact in the field of technology.

Latest Patents

One of his latest patents is a supply control apparatus and power supply control method. This invention involves a power supply control apparatus that manages the turn-on and turn-off of power to a load via a switch section. The drive signal producing section generates a drive signal for controlling the ON/OFF operations of the switch section based on an activation signal from an activating section. Additionally, a standby power supply provides operational power to the activating section and the drive signal producing section. A power failure monitoring section produces an energization signal that indicates the status of the main power supply output, which is then used by the activating section to output the activation signal.

Another notable patent is related to a CATV communication system, which includes a center device and multiple terminal devices. The center device transmits downstream timeslots to the terminal devices, which contain upstream timeslot occupancy information and collision information. This system allows terminal devices to detect vacant upstream timeslots and send data to the center device while managing potential collisions effectively.
