Title: Hisatoshi Nodera: Innovator in Proximity Switch Technology

Introduction

Hisatoshi Nodera is a prominent inventor based in Kusatsu, Japan. He has made significant contributions to the field of electronics, particularly in the development of advanced proximity switch technologies. With a total of 7 patents to his name, Nodera's work has had a substantial impact on the industry.

Latest Patents

One of Nodera's latest inventions is the "High Frequency Oscillation Proximity Switch." This innovative device includes a current feedback type oscillator that allows for the detection of nearby objects by monitoring the decline in oscillation output. To enhance the recovery speed of the oscillation after detecting an approaching object, Nodera's design incorporates a second comparison circuit. This circuit varies the feedback current to maintain the oscillation level, even when an object is very close to the switch. This invention is particularly useful in environments with strong AC magnetic fields.

Another notable patent is the "Power Source Reset Circuit for Contactless Switch." This circuit is designed to deactivate a contactless switch for a specific time interval, preventing erroneous outputs during unstable power conditions immediately after activation. Nodera's use of a Miller integration circuit, which includes a current mirror circuit, enhances the reliability of the delay mechanism. This invention is beneficial in applications where the power source for the contactless switch is frequently turned on and off.
