  • Publication number: 20200231005
    Abstract: A steel cord includes a two-layer stranded construction including a core in which two or three core filaments are twisted, and including a one-layer outer sheath in which outer sheath filaments are helically wound around the core and along a longitudinal direction of the core. The core filaments have same filament diameters as the outer sheath filaments, length of lay for the core is same as length of lay for the outer sheath, and length of lay/filament diameter, which indicates a ratio of length of lay to a filament diameter, is between 50 and 75. Two or more filaments selected from among the core filaments and the outer sheath filaments, are crimped filaments each including bent sections and non-bent sections that are repeatedly disposed along the longitudinal direction.

  • Patent number: 8691368
    Abstract: A thermally conductive sheet comprises a thermally conductive polymer layer, an adhesive layer provided on an outer surface of the thermally conductive polymer layer, and a thermal diffusion layer, which is a functional layer provided on the adhesive layer. The thermally conductive polymer layer is formed of a thermally conductive polymer composition containing a polymer matrix and a thermally conductive filler. The coefficient of static friction of the thermally conductive polymer layer is 1.0 or lower. The adhesive layer has an outer shape smaller than that of the thermally conductive polymer layer.
