Masaru Kitaguchi 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).

  • Refrigeration system consisting of a plurality of refrigerating cycles
    Patent number: 5347831
    Abstract: The present inventions are intended to improve heat efficiency of a refrigeration system having plural refrigerating cycles of different evaporating or condensing temperatures typically used in breweries. Each of main lines of different evaporating temperatures are connected with each of suction lines to a compressor respectively, to enable the system to save energy and to establish a back-up system of compressors. A different condensing temperature system having a common refrigerant source is provided with refrigerant transferring means to transfer refrigerant from an refrigerant excess cycle to an refrigerant insufficiency cycle.
    Type: Grant
    Filed: June 16, 1993
    Date of Patent: September 20, 1994
    Assignees: Mayekawa Mfg. Co., Ltd, Asahi Breweries, Ltd.
    Inventors: Masaru Kitaguchi, Shigeru Sakashita
