Title: Innovations of Hideki Shiratori
Introduction
Hideki Shiratori is a notable inventor based in Sendai, Japan. He has made significant contributions to the field of technology, particularly in the area of detection apparatus and radar equipment. With a total of 4 patents to his name, Shiratori's work showcases his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Moving Object Detection Apparatus." This invention utilizes an oscillating output from a gate of a Field Effect Transistor (FET) functioning as an oscillator. The output is coupled via a resonant line to a transmit-receive antenna. A wave transmitted from the antenna and returned as a reflected wave is received at the gate. The beat signal component output from the gate, due to a phase difference between the transmitted wave and the reflected wave, is taken as a moving object detection signal.
Another significant patent is the "FM-CW Radar Equipment." This invention addresses a conventional problem of failure detection caused by the carrier level of amplitude modulation dispersing too largely to adjust to a constant level within a criterion range. A novel method is applied based on the observation that a noise level greatly varies upon the occurrence of a failure in a radio-frequency circuit. A failure can be detected by comparing the varied noise level with a noise level in normal conditions. This method allows for the configuration of FM-CW radar equipment with a simple structure for detecting failures in transmission and reception circuits.
