Masateru Ichikawa 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: 10126493
    Abstract: Method and apparatus for producing metal-coated optical fiber involves feeding a length of glass fiber through a first solution bath so as to plate a first predetermined metal on the glass fiber via electroless deposition. The length of glass fiber is passed continuously from the first solution bath to a second solution bath adapted to plate thereon a second predetermined metal via electrolytic plating such that the optical fiber contacts an electrode only after at least some of the second predetermined metal has been applied. The length of glass fiber may be passed continuously from the second solution bath to a third solution bath adapted to plate thereon a third predetermined metal via electrolytic plating.
    Type: Grant

  • Patent number: 10015890
    Abstract: A method of manufacturing a conductive layer on a support body includes a first process of forming a precursor layer containing at least one of metal particles and metal oxide particles on the support body; a second process of forming a sintering layer by irradiating an electromagnetic wave pulse on the precursor layer; and a third process of compressing the sintering layer. The conductive layer is formed by repeating the first to third processes “N” times, where “N” denotes a natural number equal to or greater than 2, on the same location of the support body, and the third process performed in the first to (N?1)th operations includes forming a surface of the sintering layer in an uneven shape.

  • Patent number: 8017876
    Abstract: In a terminal portion having a copper or a copper alloy wiring according to one embodiment, the terminal portion being of a flexible print circuit board or a flexible flat cable and for connecter-fitting to a connector by being pressed by a connector pin, the copper or the copper alloy wiring having a pure tin or a lead-free tin alloy plating layer formed thereon is thermally treated so as to form an inter-metal compound including copper and tin on the copper or the copper alloy wiring, and a remaining thickness of the pure tin or the lead-free tin alloy plating layer is from 0.2 ?m to 1.6 ?m, wherein as an initial plating layer, a thickness of the pure tin or the lead-free tin alloy plating layer formed on the copper or the copper alloy wiring is from 1.5 ?m to 5.0 ?m, and a thickness of the inter-metal compound including copper and tin is from 0.1 ?m to 3.5 ?m.
