Title: Yorinobu Murayama: Innovator in Object Detection and Motor Drive Technology

Introduction

Yorinobu Murayama is a notable inventor based in Moriguchi, Japan. He has made significant contributions to the fields of object detection and motor drive technology. With a total of 3 patents to his name, Murayama's work reflects a commitment to innovation and efficiency.

Latest Patents

One of Murayama's latest patents is an object detecting device that utilizes a pyroelectric sensor. This device provides a sensing current, which is amplified by a voltage amplifier. The level monitor then generates a detection signal when the amplified voltage exceeds a predetermined threshold. The device features a standby mode that conserves power by limiting the source current to the voltage amplifier. When the low amplified voltage surpasses a preliminary threshold, a wake-up signal is triggered, switching the device to an operational mode for enhanced performance. This design significantly reduces power consumption in the absence of activity.

Another notable patent is a motor drive circuit and system. This circuit includes a first transistor at the drive stage, a second transistor at the output stage, and a third transistor for short braking operations. These components are integrated within a common substrate, allowing for efficient operation. A parasitic transistor is formed to manage current flow during braking, enhancing the overall functionality of the motor drive system.
