Kimio Uchiyama has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Organic semiconductor electrolyte capacitor and process for producing the same
    Patent number: 4735823
    Abstract: An organic semiconductor electrolyte capacitor and a process for producing such a capacitor having improved loss and impedance characteristics and which can be produced using a simple apparatus and with reduced waste of expensive materials. A dielectric oxide film is formed on the surface of a metal anode, and a solid-electrolyte layer is formed on the dielectric oxide film. The electrolyte layer is made by melting and solidifying a mixture of an isopropylisoquinolinium tetracyanoquinodimethane complex salt and a lactone compound.
    Type: Grant
    Filed: September 15, 1986
    Date of Patent: April 5, 1988
    Assignee: Nippon Chemi-Con Corporation
    Inventors: Takato Ito, Akihiro Shimada, Kimio Uchiyama
