Title: Kimmochi Togawa: Innovator in Sensor Technology
Introduction
Kimmochi Togawa is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of sensor technology, particularly in the development of innovative coatings and electrodes for gas sensors. With a total of 2 patents, his work has garnered attention for its practical applications in various industries.
Latest Patents
Togawa's latest patents include an article and method for forming a porous coating on an electrode layer. This porous coating effectively restricts the flow of gas under measurement relative to the electrode layer of the sensor. It protects the electrode against detrimental influences by spraying fine particles of a heat-resistant and chemically stable material at high temperatures onto the electrode surface. This process forms a porous layer with moderate-sized pores, which is then impregnated with an aqueous dispersion of similar fine particles and baked to achieve the desired pore size and total volume.
Another significant patent is for an oxygen sensor featuring a noncatalytic electrode. In this design, at least one electrode exposed to a gas mixture is made of carbon silicide, which avoids catalyzing oxidation reactions. The sensor demonstrates a precise and noticeable dependence of its output voltage on the oxygen concentration in a gas mixture, particularly in non-equilibrated states such as engine exhaust gases.
