Patents by Inventor Kumiko Hirochi

Kumiko Hirochi 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).

  • Superconductor
    Patent number: 5998337
    Abstract: Excellent films of a high Tc superconductor are easily produced on metal coated substrates at a temperature below 700.degree. C. These metal buffer films are made of Pt, Au, Ag, Pd, Ni or Ti. The film superconductivity is significantly improved by the metal buffer layer. Since it is easy to form this metal coating on a substrate, the invention can increase the potential number of usable substrates such as fibers, amorphous solids or semiconductors.
    Type: Grant
    Filed: November 9, 1998
    Date of Patent: December 7, 1999
    Assignee: Matsushita Electric Industrial Co., Ltd.
    Inventors: Shinichiro Hatta, Hidetaka Higashino, Kumiko Hirochi, Hideaki Adachi

  • Wear-protected device
    Patent number: 4877677
    Abstract: A hard carbon film (12) is formed by ion-beam sputtering on a surface of a substrate (11) such as glass lens or metal sheet of a magnetic disk or a plastic film of a magnetic video tape, by selecting the direction of the ion-beam in the sputtering process to be parallel with surface of the substrate (11) of a magnetic disk, and subsequently theroen a lubricative film (13), such as ZnS.sub.2 is formed also by ion-beam sputtering.
