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.

In the method of manufacturing the inductor, a magnetic material formed by kneading a magnetic material and a resin is molded to form a magnetic material compact body in which the internal conductor is partially exposed from the external surface thereof, and then the surface of the magnetic material compact body is plated to form the external electrodes including a plated metal film and connected to the internal conductor. The surface of the magnetic material compact body is roughened, and then the external electrodes are formed via plating.

摘要： A method of manufacturing a bead inductor prevents deformation of a metal coil or dislocation of the axis position of the metal coil caused by injection pressure at the time of injecting a molten resin material from a gate. A coil is fitted onto a coil supporting pin provided on a first lower mold used for injection molding in a cavity of the mold such that the inner periphery of the coil is in close contact with the coil supporting pin. A molten, resin material is injected into the cavity. Then, the coil supporting pin and the first lower mold are removed from the molded product, and a second lower mold without a coil supporting pin is provided for replacing the first lower mold. A molten resin material is injected into the space which had been occupied by the coil supporting pin. After removing the hardened resin molded product from the mold for injection molding, the end parts of the coil are cut so as to be exposed.
