Norimasa Shinada 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: 9688868
    Abstract: A conductive polymer dispersion is provided which is capable of easily forming a conductive coating film having both excellent water resistance and excellent solvent resistance. The conductive polymer dispersion of the present invention includes a ?-conjugated conductive polymer, a polyanion, a polyester resin having an alkali metal salt of an acid group, and a glycidyl group-containing acrylic resin. In the conductive polymer dispersion, the ratio (?/?) of total mass ? of the polyester resin and the glycidyl group-containing acrylic resin to total mass ? of the ?-conjugated conductive polymer and the polyanion is in a range of 6.90 to 62.5.
    Type: Grant

  • Publication number: 20110299222
    Abstract: The present invention provides a method for manufacturing a film for a film capacitor in which a film can be prepared by melt extrusion molding in a thin film having a thickness of 10 ?m or less and in which a cost can be cut by simplifying a manufacturing step thereof and a film for a film capacitor. It is a method for manufacturing a film for a film capacitor comprising the steps of charging a melt extrusion molding equipment 10 with a molding material 1 to mold a film 20 for a film capacitor by extruding from a dice 12, interposing the above extruded and molded film 20 for a film capacitor between a pressing roll 31 and a metal roll 32 to cool it and winding up the cooled film 20 for a film capacitor having a thickness of 10 ?m or less in order on a winding tube 41 of a winding device 40, wherein the molding material 1 is prepared by adding a fluorocarbon resin to a PEI resin having a glass transition point of 200° C.
