Title: Innovations of Hidehiro Tomioka
Introduction
Hidehiro Tomioka is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of electronics, particularly in the development of innovative circuits and switches. With a total of 3 patents to his name, Tomioka's work has had a considerable impact on the industry.
Latest Patents
One of Tomioka's latest inventions is a power source reset circuit for contactless switches. This circuit is designed to deactivate a contactless switch for a specific time interval, preventing erroneous outputs during unstable power conditions. The reliability of this circuit is enhanced by a Miller integration circuit, which includes a current mirror circuit for amplifying electric current. Additionally, a switching device can be connected across the capacitor to quickly discharge the charge when the power is turned off, preparing the circuit for subsequent actions when the power is turned on again. This invention is particularly useful in applications where the power source for the contactless switch is frequently toggled.
Another significant invention is a proximity switch that utilizes a current feedback time oscillator. This switch detects nearby objects by monitoring the decline in oscillation output. To improve the recovery speed of the oscillation after detecting an object, Tomioka's design includes a second comparison circuit that adjusts the feedback current to maintain a low oscillation level, even when an object is very close. This increased response speed allows the proximity switch to function effectively in environments with strong AC magnetic fields.
