Takehiro Kounoike 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).

  • Method of making a high frequency non-reciprocal circuit element
    Patent number: 5662754
    Abstract: A high-frequency non-reciprocal circuit element comprises a high-frequency-use magnetic layer and a plurality of center electrodes arranged therein to intersect with each other while being electrically insulated from each other. The plurality of center electrodes are advantageously embedded in the high-frequency-use magnetic layer or layers to be integrated with the same.
    Type: Grant
    Filed: October 12, 1994
    Date of Patent: September 2, 1997
    Assignee: Murata Manufacturing Co., Ltd.
    Inventors: Hiroshi Marusawa, Takashi Kawanami, Takehiro Kounoike, Kunisaburo Tomono
  • Method of manufacturing microwave magnetic material body
    Patent number: 5620543
    Abstract: A microwave magnetic material body for use in a microwave non-reciprocal circuit element is constructed by sintering a laminated body obtained by laminating a plurality of magnetic sheets.
