  • Positive-temperature-coefficient thermistor heating device
    Patent number: 4482801
    Abstract: A positive-temperature-coefficient (PTC) thermistor heating element in which joints between metal heat radiating means and the electrodes on a positive-temperature-coefficient thermistor element are attained only with an electrically insulative adhesive in such a way that prior to and during the curing step, the heat radiating means are pressed against the electrodes to establish thereby electrical contacts at least partially between them. The heat radiating means also function as current paths to and out, respectively, of the thermistor element. The PTC thermistor heating device is simple in construction and easy to fabricate at less cost yet has a high and stable thermal output.
    Type: Grant
    Filed: December 14, 1982
    Date of Patent: November 13, 1984
    Assignee: Matsushita Electric Industrial Co., Ltd.
