Kazuo Ihara 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).

  • Apparatus for producing high viscosity materials and method of producing the same
    Patent number: 5683178
    Abstract: Agitator blades formed by connecting a plurality of frame members are provided in a cylindrical or conical container to realize the agitator blade structure without rotary shaft. Therefore, less liquids being treated adhere onto the rotary shaft or the agitator blades and less residue of the liquids is formed, making it possible to obtain a final high viscosity polymer using the same agitator vessel preventing the quality from being deteriorated.
    Type: Grant
    Filed: August 18, 1993
    Date of Patent: November 4, 1997
    Assignee: Hitachi, Ltd.
    Inventors: Hidekazu Nakamoto, Chikao Oda, Norio Nakazato, Morihisa Maruko, Kazuo Ihara, Takatoshi Kinoshita, Tokinobu Furukawa, Kenichi Watanabe

  • Vibration-controlling bearing
    Patent number: 4602873
    Abstract: A vibration-controlling bearing for controlling vibration developing in a rotary shaft supported in a housing of a rotary machine including a bearing member of a cylindrical shape interposed between an outer peripheral surface of the rotary shaft and an inner peripheral surface of the housing and spaced apart therefrom by respective gaps. A dynamic pressure is generated between an inner peripheral surface of the bearing member and the outer peripheral surface of the rotary shaft. Communicating ducts are formed in the bearing member for transmitting a portion of the dynamic pressure generated to a gap between the outer peripheral surface of the bearing member and the inner peripheral surface of the housing.
