Toshifumi Miyasaka 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).

  • Thermotropic liquid crystal polymer composition and insulator
    Patent number: 5490319
    Abstract: The improved thermotropic LCP composition comprises 10-13 wt. % of a thermotropic liquid crystal polymer resin and 90-87 wt. % of zircon and is useful as an electrical insulator. The composition is a good electrical insulator, permits good heat conduction and experiences small thermal expansion, thus insuring high reliability. The composition may be injection molded to form an electrically insulated housing of a stator for electric machines or appliances that includes a coil and terminals thereof.
    Type: Grant
    Filed: August 3, 1994
    Date of Patent: February 13, 1996
    Assignee: Ebara Corporation
    Inventors: Toshio Nakamura, Yoshimi Soeda, Toshifumi Miyasaka, Minoru Iwata
