Title: Nobuo Terui: Innovator in Information Read Devices and Distortion Measurement

Introduction

Nobuo Terui is a notable inventor based in Kodaira, Japan. He has made significant contributions to the field of electronics, particularly in the development of information read devices and distortion measurement circuits. With a total of two patents to his name, Terui's work showcases his innovative approach to solving complex technical challenges.

Latest Patents

Terui's latest patents include an information read device and a distortion factor meter circuit. The information read device is designed to read the information of a coded AC signal, where a bit '1' is represented by one cycle of an AC signal and a bit '0' by its absence. This device incorporates a first square wave converter and a second square wave converter to generate corresponding square wave signals for positive and negative components of the coded AC signal. The gate means selectively passes one of these signals based on the polarity of the AC signal, allowing for effective information retrieval.

The distortion factor meter circuit is another of Terui's innovations, aimed at measuring the harmonic distortion factor of a signal. This circuit includes a first transmission line that shapes a signal with a harmonic component to produce a DC signal, which is then converted into a square wave. A second transmission line produces a second signal with a residual harmonic component, and a voltage comparator generates a digital signal based on the levels of the output signals from both transmission lines. An integration circuit is also included to integrate the output from the voltage comparator.
