Masanobu Matsuguchi 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).

  • Moisture sensitive element and method of manufacturing the same
    Patent number: 6428717
    Abstract: A hydrophilic polymer material such as polyvinyl alcohol is formed into a porous film (301). A film (holding film) (303) made from a hydrophobic polymer material such as polyvinyl acetate is formed on the inner walls of a large number of pores (302) formed in the porous film (301). Lithium chloride (304) is held in these pores (302).
    Type: Grant

  • Moisture sensitive element and method of manufacturing the same
    Patent number: 6126312
    Abstract: A moisture sensitive element in which a functional film is formed in contact with opposing electrodes arranged on a substrate. The element includes a mechanism for measuring the temperature of the functional film. The functional film has a porous structure made from a polymer material with hydrophilic properties and includes fine pores. A holding film is formed on inner walls of the pores and made from another polymer material having hydrophobic properties. An electrolytic salt is held within the pores.

  • Moisture sensitive element and method of manufacturing the same
    Patent number: 5161085
    Abstract: A moisture sensitive element includes a moisture sensitive film consisting of a polymer obtained by polymerizing and crosslinking a fluorine-containing polyimide oligomer or a polyisoimide oligomer having acetylene as a terminal group and its isomer. The moisture sensitive element also includes electrodes formed on upper and lower surfaces of the moisture sensitive film.
