Introduction

Shinichi Harima is a notable inventor based in Fujimi, Japan. He has made significant contributions to the field of water quality analysis, holding a total of 8 patents. His work focuses on developing advanced technologies that enhance the accuracy and efficiency of water quality measurement.

Latest Patents

One of his latest inventions is a water quality analyzer. This device comprises sensor electrodes made of different metals, which generate a sense voltage in proportion to the liquid's impurities concentration. An operational amplifier amplifies the sense voltage without inverting it, providing input for a CPU. A resistor connects to the electrode, while a voltage divider applies a voltage obtained by dividing the sense voltage by a prescribed division ratio. The CPU calculates the input signal to obtain chlorine concentration and displays the result on an LCD in measurement mode. Additionally, it sets the division ratio of the divider so that the sense voltage across electrodes soaked in a liquid with a prescribed concentration of chloride approximately agrees with a reference voltage during calibration.
