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： 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 and a current limiting device for being built into a power supply circuit of a color television receiver or color monitor display or the like with which it is possible to effect a reliable demagnetizing operation using existing components and without using either a positive characteristic thermistor which reaches a high temperature or a relay circuit. The demagnetizing circuit is connected in parallel with a power supply circuit having a smoothing capacitor and a negative temperature characteristic thermistor or fixed resistance for suppressing surge currents to the smoothing capacitor. It has a thermally actuated switch connected in series with one end of a demagnetizing coil by way of a positive temperature characteristic thermistor which is actuated by heat produced by the temperature negative characteristic thermistor or fixed resistance to cut off a demagnetizing current. The current limiting device within the demagnetizing circuit includes the negative temperature characteristic thermistor or fixed resistance, the positive temperature characteristic thermistor and the thermally actuated switch interposed between the negative temperature characteristic thermistor or fixed resistance and the positive temperature characteristic thermistor. The thermally actuated switch has a thermally actuated member which is caused to bend by heat produced by the negative characteristic temperature thermistor or fixed resistor, and a moving contact point and a fixed contact point which are opened by this bending of the thermally actuated member.

摘要： A thermistor includes a plate-like thermistor body and a first and a second electrode formed on each of the main surfaces of said plate-like thermistor body. The first electrode is formed so that its outer periphery reaches the outer peripheral edge of the thermistor and the second electrode is formed to extend from the area encircled by said first electrode onto the first electrode but not reach the outer periphery of the first electrode. The first and second electrodes are made of material which can make an ohmic-contact with the main surface of said thermistor body. The first electrode is made of the material which is hard to generate inter-electrode migration and said second electrode is made of the material which is easy to generate the inter-migration compared with the first electrode. Thus, the thermistor can prevent short-circuiting due to inter-electrode migration without deteriorating the characteristic such as a current capacity.

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.
