Tsuneo Kamiyahata 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).

  • Resin composition with high thermal conductivity and method of producing the same
    Patent number: 6995205
    Abstract: A resin composition having high thermal conductivity and excellent moldability and a method of producing the same is provided. The composition includes 40 vol % or more of a matrix resin, 10 to 55 vol % of a thermally conductive filler dispersed in the matrix resin and the balance of a low-melting point alloy connecting the thermally conductive filler to each other and having a melting point not higher than 500° C. The proportion of the volume ratio of the low-melting point alloy to that of the thermally conductive filler is set in a range from 1/30 to 3/1.
    Type: Grant
