摘要： A magnetic bubble memory device comprises a cassette and a body. The cassette has a bias magnetic field generator adapted to generate a bias magnetic field for sustaining magnetic bubbles within a bubble memory chip and is removed of coils adapted to generate a rotating magnetic field for propagation of the magnetic bubbles. The body has a rotating magnetic field generator. The cassette is mounted to or dismounted from the body. When the cassette is dismounted from the cassette, information stored in the chip is held by the bias magnetic field generator and when the cassette is mounted to the body, information is read from or written into the chip by the rotating magnetic field generator.

摘要： A litz wire comprises three or more insulated strands consisting essentially of an inner conductor and an outer insulating layer on said conductor. The strands are twisted symmetrically with respect to the center line of the wire, so that a current density distribution in the litz wire becomes uniform. Three or more such litz wires are twisted to form a composite litz wire. The composite litz wires are suitable for use in a high-frequency coil.

摘要： A shielding method which utilizes a three dimensional structure and is effective to a source of the electromagnetic radiation noise, and a circuit board employing the same are obtained. Further, for the purpose of making the shielding function at an enclosure level unnecessary and realizing the recycling of enclosure materials by using this circuit board, in a circuit board structure having at least a signal layer, a power source layer and a ground layer, a signal line on the signal layer which is sandwiched between the two conductor layers made up of the power source layer and the ground layer, or the power source layers or the ground layers, is enclosed in a three dimensional manner with the conductor layers, thereby to form a single or double electrical closed loop current path or paths. By adopting this structure, there is obtained the effect that the electromagnetic radiation noise radiated from the circuit board is greatly reduced. In addition, as a result, there is obtained the effect that since the shielding processing required for the enclosure becomes unnecessary, the enclosure materials can be recycled.
