  • Patent number: 10920051
    Abstract: The present invention is a resin composition including: a resin component; zinc oxide; and an acetic acid remover, wherein the resin component includes an ethylene-vinylacetate copolymer and a content of the ethylene-vinylacetate copolymer in the resin component is greater than or equal to 10% by mass, wherein the acetic acid remover is an acid acceptor, a nitrogen-containing aromatic heterocyclic compound having a mercapto group, or a combination thereof, and wherein a mass ratio of the zinc oxide to the ethylene-vinylacetate copolymer is greater than or equal to 0.06 and less than or equal to 0.20.
    Type: Grant

  • Patent number: 9704615
    Abstract: A shielded cable comprising two insulated wire covered with first and second metal clad resin tapes each of which has a laminated metal layer and a resin layer. The first metal clad resin tape covers the circumference of the two insulated wires by open-wrapping and the second metal clad resin tape is spirally wrapped around the circumference of the first metal clad resin tape. The first and second metal clad resin tapes are disposed while the metal layers face each other and, in the portion where the second metal clad resin tape is overlapped by wrapping, the metal layer of the overlapped one second metal clad resin tape and the metal layer of the other second metal clad resin tape are in contact with the first metal clad resin tape. The shielded cable can prevent sharp signal attenuation in a high frequency region and is easy to bend and flexible.

  • Patent number: 8859902
    Abstract: A multi-core cable in which skew occurs less and attenuation characteristics of all core cables are uniform comprises: a core unit; an insulation tape spirally wrapped around the outer circumference of the core unit; and a metal coated resin tape wrapped over the insulation tape, wherein a plurality of core cables each consisting of two insulated wires arranged in parallel are stranded together to form the core unit, and wherein the metal coated resin tape is wrapped in the same direction as the stranding direction of the core cables.

  • Publication number: 20110247856
    Abstract: There is provided a shielded cable wherein a metal coated resin tape is helically wound, whereby a plurality of signal cables are shielded, and no sudden signal attenuation occurs in high frequency ranges. A shielded cable has a shield conductor produced by helically winding a metal coated resin tape together around the circumference of a plurality of signal wires, upper and lower metal foils are in electrical contact with each other in overlap parts of the winding of the metal coated resin tape. The metal coated resin tape is formed with one edge part folded back so that the metal foil is disposed on an outward side. The overlap width of the winding of the metal coated resin tape is one-quarter to one-half of the tape width.
