Takuji Aoyama 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).

  • Patent number: 11056632
    Abstract: A thermoelectric conversion substrate includes an insulating substrate and at least one thermoelectric conversion unit. The insulating substrate has a first surface and a second surface at both sides of the insulating substrate in a thickness direction. The at least one thermoelectric conversion unit is incorporated in the insulating substrate. The at least one thermoelectric conversion unit includes a first thermoelectric member, a second thermoelectric member, and a first electrode disposed on the first surface of the insulating substrate. The first thermoelectric member includes a first tubular member having insulation property and a first semiconductor filled in the first tubular member. The second thermoelectric member includes a second tubular member having insulation property and a second semiconductor filled in the second tubular member. The second semiconductor has carriers different from carriers of the first semiconductor.

  • Publication number: 20100297453
    Abstract: The present invention provides an insulating sheet which is used for bonding a heat conductor having a thermal conductivity of 10 W/m·K or higher to an electrically conductive layer. The handleability of the insulating sheet is excellent when it is uncured, and a cured product of the insulating sheet has higher adhesion, heat resistance, dielectric breakdown characteristics, and thermal conductivity.
