  • Patent number: 11929189
    Abstract: The present application discloses a filtering cable, which solves the problem that the cable in the related art cannot ensure a simple and reasonable structural design while having good filter performance. One or several core wires and N defective conductor layers surrounding the core wires are sequentially provided from inside to outside in the cross section in the radial direction of the filtering cable; wherein the defective conductor layer has an etching pattern; the etching pattern is distributed in the axial direction of the filtering cable; the etching pattern is used to make the filtering cable equivalent to a preset filter circuit to filter the signal transmitted in the filtering cable.

  • Patent number: 8236576
    Abstract: A magnetic logic element with toroidal magnetic multilayers (5,6,8,9). The magnetic logic element comprises a toroidal closed section which is fabricated by etching a unit of magnetic multilayers (5,6,8,9) deposited on a substrate. Optionally, the magnetic logic element may also comprise a metal core (10) in the closed toroidal section. Said magnetic multilayers (5,6,8,9) unit is arranged on the input signal lines A, B, C and an output signal line O, and then is made into a closed toroidal. Subsequently, on the toroidal magnetic multilayered unit (5,6,8,9), the input signal lines A?, B?, C? and an output signal line O? are fabricated by etching. This magnetic logic element can reduce the demagnetization field and the shape anisotropy effectively, leading to the decrease of the reversal field of magnetic free layer. Furthermore, this magnetic logic element has stable working performance and long operation life of the device.

  • Patent number: 7936595
    Abstract: Each layer in the magnetic multilayer film is a closed ring or oval ring and the magnetic moment or flux of the ferromagnetic film in the magnetic unit is in close state either clockwise or counterclockwise. A metal core is put in the geometry center position in the close-shaped magnetic multilayer film. The cross section of the metal core is a corresponding circular or oval. A MRAM is made of the closed magnetic multilayer film with or without a metal core. The close-shaped magnetic multilayer film is formed by micro process method. The close-shaped magnetic multilayer film can be used broadly in a great variety of device that uses a magnetic multilayer film as the core, such as MRAM, magnetic bead in computer, magnetic sensitive sensor, magnetic logic device and spin transistor.
