Patents by Inventor Koichi Fukata

Koichi Fukata 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).

  • Battery, method of manufacturing the same, method of manufacturing weldment, and pedestal
    Patent number: 7727672
    Abstract: A metal plate and an electrode in a polymer lithium ion secondary battery or the like are welded certainly, and it is accomplished to further improve the reliability and the durability thereof. Each of an upper metal plate (7a) and a lower metal plate (9a) on the positive pole/terminal is welded to a pole/terminal of positive electrode (3) so that the pole/terminal of positive electrode (3) may be sandwiched from each of the upper and lower sides. Moreover, each of an upper metal plate (7b) and a lower metal plate (9b) on the negative pole/terminal is welded to a pole/terminal of negative electrode (5) so that the pole/terminal of negative electrode (5) may be sandwiched from each of the upper and lower sides. This eliminates occurrence of poor welding in the electric resistance welding.
    Type: Grant
    Filed: January 24, 2006
    Date of Patent: June 1, 2010
    Assignee: Sony Corporation
    Inventors: Kiyoshi Kikuchi, Koichi Fukata, Bunya Sato, Shuji Sasaki, Chiaki Anzai, Hiroshi Anzai
