Patents by Inventor Hideaki Tatsuta

Hideaki Tatsuta 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: 7938636
    Abstract: A fluorescence-containing material injection apparatus of the present invention includes a fluorescence-containing material temperature control section, a fluorescence-containing material stirring section, a fluorescence-containing material remaining amount sensor, and a fluorescence-containing material injection amount adjustment section, by which disproportion in the mixture ratio of contaminates in a fluorescence-containing material M is restrained. This makes it possible to evenly apply a fluorescence-containing material onto a semiconductor light emitting element.
    Type: Grant
    Filed: August 2, 2007
    Date of Patent: May 10, 2011
    Assignee: Sharp Kabushiki Kaisha
    Inventors: Toshio Hata, Hideaki Tatsuta, Hiromu Tagashira, Taiji Morimoto
