Title: Junko Yanagitani: Innovator in Water Quality Analysis

Introduction

Junko Yanagitani is a prominent inventor based in Itami, Japan. She has made significant contributions to the field of water quality analysis, holding a total of 3 patents. Her innovative work focuses on developing advanced technologies to ensure the safety and quality of water.

Latest Patents

One of her 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. The system includes a resistor connected to the electrode and a voltage divider that 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 in a sense-voltage calibration mode.

Career Highlights

Throughout her career, Junko has worked with notable companies such as Fis Inc. and Tanita Corporation. Her experience in these organizations has contributed to her expertise in developing innovative solutions for water quality monitoring.
