Kouji Mizohata 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).

  • Hydrophilic surface treating aqueous solution, hydrophilic surface treating method and hydrophilic surface treating film
    Patent number: 5494705
    Abstract: It is the object of the present invention to provide a hydrophilic surface treating aqueous solution, hydrophilic surface treating method, and hydrophilic surface treating film with lasting hydrophilicity and ensuring a film having a good processability. The hydrophilic treating aqueous solution contains as main components a hydrophilic polymer having a specific molecular weight and containing a polyoxyalkylene chain of 10 wt % or more in terms of solid content, and a specific aqueous resin. This enables the formation of film with good processability and good hydrophilicity and persistency of hydrophilicity on the surface of aluminum or aluminum alloy for use in aluminum fins of a heat exchanger, as well as suppressing the generation of unpleasant odor.
    Type: Grant
    Filed: March 28, 1995
    Date of Patent: February 27, 1996
    Assignee: Nippon Paint Co., Ltd.
    Inventors: Katsuyoshi Yamasoe, Fujio Mikami, Hidekimi Hirasawa, Masahiko Matsukawa, Kouji Mizohata
