  • Patent number: 6369318
    Abstract: 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.

  • Patent number: 6054649
    Abstract: 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.

  • Patent number: 5977854
    Abstract: An electromagnetic noise absorber has a pair of ferrite cores arranged with open ends of the ferrite cores facing each other. Each of the ferrite cores includes an axial portion, an outer cylindrical portion and a bottom portion and is constructed by coupling an end of the axial portion and an end of the outer cylindrical portion to the bottom portion. A slot is formed in the outer cylindrical portion and the bottom portion of each ferrite core such that the slot extends from the open end of the outer cylindrical portion to the bottom portion. The electromagnetic noise absorber can be easily attached to a signal line by placing the signal line in the slots and turning one of the ferrite cores. Since the signal line are wound around the axial portion of the ferrite cores, the signal line has a high impedance.

  • Patent number: 5420553
    Abstract: A noise filter includes a plurality of resistance patterns arranged in parallel, and a ground pattern opposed to the resistance patterns via a dielectric substrate. Distribution capacitance is caused between the resistance patterns and the ground pattern. The function of the noise filter comes from the distribution capacitance and the resistance of the resistance patterns as the RC composite elements. The noise filters can be connected in plural. Noise can be eliminated without twisting the effective signal components in a compact noise filter.
