Title: Ryuji Kojima: Innovator in Waste Treatment and Humidity Sensing Technologies
Introduction
Ryuji Kojima is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of waste treatment and humidity sensing technologies. With a total of three patents to his name, Kojima's work reflects a commitment to innovation and environmental sustainability.
Latest Patents
Kojima's latest patents include a method for treating cyanide waste liquid and a humidity sensor. The method for treating cyanide waste liquid provides a highly reliable detoxifying approach for cyano materials. This process involves heating waste liquor containing free cyano material, a cyano complex, and a reducing compound under alkaline conditions. The oxidation-reduction potential of the waste liquor is measured, and hypochlorite is added until the desired oxidation-reduction is achieved.
The humidity sensor developed by Kojima utilizes a chemical conversion coating that decreases impedance with moisture adsorption. This innovative sensor features an extremely short electrode distance, improved sensitivity, high-speed response, and stable long-term performance. The chemical conversion coatings used include phosphate, oxalate, and chromium phosphate, among others.
