摘要： A PTC thermistor has its substrate entirely coated with an insulating glass material except for the area where a silver electrode is formed. Such a thermistor may be produced by coating a substrate with an insulating glass material, forming a silver layer on the coated substrate and fusing the silver layer with a part of the glass material so as to form an electrode adhering to the substrate. An underelectrode may be provided between the substrate and such an electrode. A resistor is formed by encasing such a PTC thermistor with a pair of spring terminals for supporting the thermistor therebetween.

摘要： Organic thermistor devices are produced by a first step of molding an organic thermistor material by covering a plurality of electrically conductive members to form a conductor-containing member, which is elongated in a longitudinal direction, has a pair of mutually oppositely facing side surfaces, having the conductive plates buried parallel to one another inside the organic thermistor material, each mutually adjacent pair of these conductive members being externally exposed on different ones of the side surfaces, a second step of forming a pair of electrodes elongated in the longitudinal direction on the side surfaces of the conductor-containing member, and a third step of thereafter cutting this conductor-containing member transversely at specified positions so as to divide into individual units.

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.

摘要： A PTC thermistor device includes three PTC thermistors aligned and disposed in a heat transmission relation to each other such that the center PTC thermistor provides heat to the other PTC thermistors which are so connected as to define a part of path for the demagnetizing current. The two PTC thermistors positioned on the opposite sides of the center PTC thermistor increase their temperature rapidly so that a rapid and effective attenuation of demagnetizing current can be obtained.

摘要： A PTC thermistor element for a heating device has a main body of a layered structure having a thinner layer and a thicker layer, sandwiched between electrodes formed on the main outer surfaces facing away from each other. The thinner layer has a thickness 0.05-0.43 times that of the thicker layer and is made of a PTC thermistor material with a Curie temperature which is lower than that of the thicker layer by 20.degree. C. or more. The center of heat generation is thus shifted towards the electrode formed on the thinner layer, and a heating plate contacting it can be effectively heated.

摘要： A degaussing circuit is formed as a series connection of a PTC element and a degaussing coil operated such that the operating frequency of the current therethrough is higher than the frequency of the power source line for the device such as a color television set in which this degaussing circuit is incorporated. This frequency conversion may be effected by a circuit which also functions to convert the alternating current from the power source line into a direct current. The degaussing circuit may further include a relay circuit for switching on and off the current through the PTC element and the degaussing coil.

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.
