    摘要: A self-temperature controlling type heating device comprises a positive temperature coefficient ceramic resistor having a thin layer portion, a first electrode provided on one face of the thin layer portion, a second electrode provided on the other face of the thin layer portion opposite to the first electrode, and at least one third electrode provided on the surface of the PTC ceramic resistor in spaced relation to the first electrode. An electric current is allowed to flow between the first and second electrodes to form a heating element, and an electric resistance value between the first and third electrodes is detected to thereby make a temperature control. Thus, a high output is obtained at a low voltage and the control temperature is freely varied.

    摘要: A positive ceramic semiconductor device having positive temperature coefficient of resistance comprises a pair of electrodes provided on a ceramic semiconductor substrate. One of the paired electrodes which is to serve as the positive pole is basically constituted by at least an electrically conductive layer of silver-palladium series containing silver and palladium at a predetermined ratio. For preventing a localized current concentration from occurring in the current conducting state, improvement is made as the structure of the positive pole electrode ormed of the electrically conductive material of silver-palladium series and/or the structure of the negative pole electrode. Silver-migration phenomenon on the positive ceramic semiconductor substrate as well as degradation of the mechanical strength thereof is positively prevented.

    摘要: A lead wire for a sensor has a conductor unit including at least stainless steel wires and copper wires. By setting the cross-sectional percentage of the stainless steel wires in the conductor unit within the range of 30 to 70%, it is possible to obtain a lead wire having low electrical resistance, and high flexibility, tensile strength and elasticity. There are preferred values in hardness and heat treatment of the stainless steel wires. The copper wires are preferably coated with an antioxidant film. The lead wire may include hybrid wires stranded together and obtained by integrally molding or forming stainless steel and copper. It is preferable that the lead wire is coated with an insulating coating material such as a Teflon type resin.

    摘要: There is provided a low-cost satellite broadcast tuner capable of receiving and processing both a QPSK modulation signal and an FM signal while assuring simple connection of an LNB (low noise block) to the tuner. A single front-end section including an RF stage, a mixer, a local oscillator circuit, an IF stage, an AGC loop is used for both an FM detector and an I/Q quadrature detector, so that both the FM signal and the QPSK modulation signal are received and processed in the single front-end section. In the above case, power supplied to the FM detector for detecting the FM signal, and power supplied to a local oscillator circuit required for detecting the QPSK modulation signal is turned off when receiving the FM signal.
