Takashi Tokiwa 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: 9920463
    Abstract: Provided is a fiber sheet for molding, characterized in that a print resin is applied on the surface of the fiber sheet containing highly crimped fibers, and the amount of the print resin is 30 g/m2 or less, and the air permeability of the fiber sheet is 5 to 30 cm3/cm2/sec. The fiber sheet for molding can be molded without generating wrinkles, and has a good sound absorbing property. When a pattern is formed with the printing resin, the fiber sheet for molding is also excellent in design properties.
    Type: Grant

  • Patent number: 8663809
    Abstract: A surface material substrate has one surface of a fiber substrate containing cellulosic fiber is bonded with an acrylic resin binder containing a flame retardant and a thermosetting resin, a fineness of fiber constituting the fiber substrate is 2.2 dtex or less, and a mass ratio of the acrylic resin to the thermosetting resin is 80:20 to 65:35. A surface material is provided with an adhesive layer containing a resin with a melting point of 200° C. or less on a surface of the fiber substrate of the surface material substrate opposite to a facing surface, which is bonded with the acrylic binder. In a molded body, the surface material is integrated with a substrate mat by heat molding via an adhesive layer. The surface material substrate simultaneously fulfills requirements of low weight and cost, design properties, flame retardancy, mold releasability, followability and trimming properties.
