  • Patent number: 9368256
    Abstract: A tubular cover is obtained by causing a fabric woven from a warp and weft to be imparted with a curl by a heat treatment, wherein the tubular cover is characterized in that the warp and/or the weft are folded yarns created by twisting together multiple strands of yarn that have already been twisted in either an S- or Z-winding-direction, the winding direction of the twisting when the folded yarn is created being the opposite of the yarn-winding direction.
    Type: Grant
    Filed: September 26, 2013
    Date of Patent: June 14, 2016
    Assignees: TOYOTA TSUSHO MATEX CORPORATION, ANDO CO., LTD.

  • Patent number: 7074470
    Abstract: A protective sleeve for a motor component includes a cylindrical-shaped braided cord of twenty-four or more strands using both a multifilament strand and a monofilament strand made of synthetic fibers having a melting point or a decomposition temperature at 280° C. or more. The protective sleeve has oil resistance at high temperatures of 50% or more, the oil resistance at high temperatures being represented by the following formula: oil resistance at high temperatures (%)=(T/T)×100. Here, T denotes a tensile strength of the protective sleeve before a treatment and T? denotes a tensile strength of the protective sleeve after the treatment. The tensile strength is measured in accordance with JIS L1013-8.5.1, and the treatment is carried out in such a manner that the entire protective sleeve is put into a closed container containing a mixture of 5 weight % of water and 95 weight % of automatic transmission fluid, followed by heating the container so that a temperature of the mixture is maintained at 150° C.

  • Patent number: 6997096
    Abstract: A binding cord for a motor for an electric vehicle includes a braided round cord of eight or more strands using a multifilament strand made of synthetic fibers having a melting point or a decomposition temperature at 280° C. or more. The binding cord has oil resistance at high temperatures of 50% or more, the oil resistance at high temperatures being represented by the following formula: oil resistance at high temperatures (%)=(T?/T)×100. Here, T denotes a tensile strength of the binding cord before treatment and T? denotes a tensile strength of the binding cord after the treatment. The tensile strength is measured in accordance with JIS L1013-8.5.1, and the treatment is carried out in such a manner that the entire binding cord is put into a closed container containing a mixture of 5 weight % of water and 95 weight % of automatic transmission fluid, followed by heating the container so that a temperature of the mixture is maintained at 150° C. for 1,000 hours.

    Abstract: A binding cord for a motor for an electric vehicle includes a braided round cord of eight or more strands using a multifilament strand made of synthetic fibers having a melting point or a decomposition temperature at 280° C. or more. The binding cord has oil resistance at high temperatures of 50% or more, the oil resistance at high temperatures being represented by the following formula: oil resistance at high temperatures (%)=(T′/T)×100. Here, T denotes a tensile strength of the binding cord before treatment and T′ denotes a tensile strength of the binding cord after the treatment. The tensile strength is measured in accordance with JIS L1013-8.5.1, and the treatment is carried out in such a manner that the entire binding cord is put into a closed container containing a mixture of 5 weight % of water and 95 weight % of automatic transmission fluid, followed by heating the container so that a temperature of the mixture is maintained at 150° C. for 1,000 hours.
