摘要： A soft magnetic core is substantially cylindrical and a linear-shaped coil conductor is inserted through a hole in the central portion of the soft magnetic core. A hard magnetic material sheet has areas which are magnetized in a thickness direction thereof and the areas are arranged in strips so that a magnetization direction of adjacent strips is mutually opposite. The hard magnetic material is wound on the outside surface of the soft magnetic core and is fixed to the soft magnetic core. The direction of the areas formed as strips of the hard magnetic material is substantially perpendicular to the axial direction of the coil conductor.

摘要： A radiant noise inhibiting assembly is constructed to inhibit a radiant noise in an electric cable connected to a digital type electronic device. The electric cable is covered by a substantially cylindrical magnetic structure which is constructed to act as a magnetic shield. A substantially cylindrical electrically conductive structure functioning as an electrostatic shield is disposed on the outside of the magnetic structure. Only a first end of the electrically conductive structure is connected to a ground of the electronic device, which first end is closer to the electronic device than a second end of the electrically conductive structure, which is not grounded. In this way, a portion of the radiant noise which is not completely absorbed by the substantially cylindrical magnetic structure is absorbed by the substantially cylindrical electrically conductive structure, thereby sufficiently inhibiting the radiant noise of the electric cable. Further, a substantially cylindrical case which is constructed to function as an electrically conductive structure and provide a function of an electrostatic shield is used. Thus, attaching such a substantially cylindrical case is the same as attaching an electrically conductive structure.

摘要： An insulated wire with a noise-suppressing function includes a ring-shaped magnetic core, a coated wire inserted into the hole of the ring-shaped magnetic core, and a securing member for securing the ring-shaped magnetic core to the coated wire. The inner diameter of the ring-shaped magnetic core, namely the diameter of the hole, is set smaller than the outer diameter of the coated wire. The coated wire is formed of a pair of parallel conductive wires, a wire-coating member for coating the pair of conductive wires, and a sheath for covering the wire-coating member. The sheath is removed at one end of the coated wire. A part of the conductive wires which is coated only with the wire-coating member is inserted into the hole of the ring-shaped magnetic core.

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.

摘要： A method for manufacturing a bead inductor includes the steps of forming a molded body of a resin material or a rubber material including a powdered magnetic substance, including a conductor coil defined by a wound, coated metallic wire embedded in the molded body; cutting both end portions of the molded body so as to expose end portions of the conductor coil; and attaching external terminals to the exposed end portions of the conductor coil so that the conductor coil is electrically connected to the external terminals. In order to increase the reliability of connection between the conductor coil and external terminals, both end portions of the conductor coil are immersed into a solder bath, prior to the molded body forming step, so as to include in the solder bath cutting regions of both end portions of the molded body therein such that soldered portions are formed by removing insulation coating on both end portions of the conductor coil.
