摘要： A semiconductor ceramic for thermistors contains zinc oxide and titanium oxide as main components and a predetermined content of manganese. Also, a chip-type thermistor including the semiconductor ceramic is provided. By adding manganese, the resistance-temperature characteristic is controllable in the range of positive temperature coefficient to negative temperature coefficient. Also, by adding nickel, the resistivity is controllable. As a result, a thermistor material which provides a series of semiconductor ceramics having various resistivities and various B constants in a low range, for example 0 to 1,000 K, is available.

摘要： A demagnetizing circuit has a positive characteristic thermistor and a demagnetizing coil connected in series with an alternating current power supply and is so constructed that it is possible to suppress the production of a low-frequency electromagnetic field. After the completion of a demagnetizing operation, the demagnetizing coil and the alternating current power supply can be completely isolated from each other, i.e. both ends of the demagnetizing coil can be electrically cut off from the alternating current power supply, so that it is impossible for residual demagnetizing current from the alternating current power supply to produce a low-frequency electromagnetic field in the demagnetizing coil. Also, preferably, at least one end of the demagnetizing coil is kept at a reference potential by way of a capacitor to dissipate any currents which may be induced in the demagnetizing coil by any influence other than the alternating current power supply.

摘要： An organic thermistor device has a pair of outer electrodes formed facing each other on end parts of a thermistor body made of an organic thermistor material. Metallic wires extend inside and through the thermistor body transversely to the direction in which the outer electrodes face each other such that the resistance value at normal temperatures of the device can be significantly reduced. Both exposed surfaces of the thermistor body not covered by the outer electrodes and exposed end surfaces of the metallic wires not covered by the thermistor body may be all covered by an electrically insulating layer. To produce such organic thermistor devices, an elongated wire-containing member is prepared by molding an organic thermistor material by covering metallic wires extending longitudinally parallel to one another. It is then entirely covered with an electrically insulating material but portions of it are removed from a pair of longitudinally continuous external peripheral surface areas. Outer electrodes are thereafter formed on this pair of surface areas and the wire-containing member is then cut transversely to the direction of its elongation at specified positions to divide into individual elements. The newly exposed surfaces of these individual elements by cutting may be covered by an electrically insulating material.
