Title: Kakusyo Yoshida: Innovator in Solid Electrolyte Capacitors
Introduction
Kakusyo Yoshida is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of solid electrolyte capacitors, holding a total of 3 patents. His innovative approaches have advanced the technology surrounding these essential components.
Latest Patents
Yoshida's latest patents focus on the production of solid electrolyte capacitors. One of his inventions provides a process for producing these capacitors by forming a dielectric oxide film and a first cathode layer of solid conductive substance over the surface of an anode body made of valve metal. The process also includes forming a second cathode layer of conductive high polymer on the first cathode layer through electrolytic oxidative polymerization. This method allows for the second cathode layer to be formed by immersing the anode body in an electrolyte and feeding a positive voltage with an external electrode piece. The feeding point is shifted at predetermined time intervals to ensure uniform thickness across the anode body.
Another patent by Yoshida elaborates on the same process but emphasizes maintaining the pH of the electrolyte within a predetermined range by adding an acid or alkali. This innovation ensures that the electrolyte remains reusable while allowing the second cathode layers to retain their desired electric conductivity.
