  • Moisture sensitive element containing high temperature decomposition residue of organo-silicon polymer as sensitive element
    Patent number: 4673910
    Abstract: A moisture sensitive element having on an insulating substrate a moisture sensitive section that changes its electrical resistance according to the humidity of atmosphere. The moisture sensitive section is prepared by mixing a polymerized organic silicon compound with particles of a moisture sensitive, electrically resistant material, applying a coat of the resulting blend onto the insulating substrate, and sintering the coat. The element is strong, has good moisture sensitivity characteristics and can be used for an extended period with little decrease in the moisture sensitivity and little change in the value of resistance.
    Type: Grant
    Filed: September 29, 1982
    Date of Patent: June 16, 1987
    Assignee: Mitsubishi Denki Kabushiki Kaisha
    Inventors: Fusaoki Uchikawa, Morihisa Takeuchi, Kozo Shimamoto, Kunihiko Miyao, Kimio Momiyama, Hisao Watarai
