Ryou Nishizakura 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: 9034419
    Abstract: A silver salt-containing layer containing a silver salt and provided on a support is exposed and developed to form a metal silver portion and a light-transmitting portion, and then the metal silver portion is further subjected to physical development and/or plating to form a conductive metal portion consisting of the metal silver portion carrying conductive metal particles. A method for producing a light-transmitting electromagnetic wave-shielding film which enables production of an electromagnetic wave-shielding material simultaneously having high EMI-shielding property and high transparency in a fine line pattern and also enables mass production of such films at a low cost, and a light-transmitting electromagnetic wave-shielding film obtained by the production method and free from the problem of moire are provided.
    Type: Grant

  • Publication number: 20140234760
    Abstract: A producing method for a translucent electromagnetic shield film comprising exposing a photosensitive material having an emulsion layer containing a silver salt and a dye on a substrate, then executing a development process to form a metallic silver portion and a light transmitting portion respectively in an exposed area and an unexposed area, and applying a physical development and/or a plating process to the metallic silver portion thereby causing the metallic silver portion to carry a conductive metal. The producing method allows to inexpensively mass produce a translucent electromagnetic shield film without a moiré pattern, having a high EMI shield property and a high transparency at the same time.
