    摘要: There are provided a lightweight insulated electric wire capable of reducing influences of external magnetic fields while having an excellent conductivity and an excellent strength and an automobile wire harness using the same insulated electric wire. There is provided a signal electric wire including a conductor portion consisting of one or more first wires and one or more second wires, which are stranded together. The first wires are constituted by metal wires made from at least one type of metal selected from a group consisting of copper, copper alloy, aluminum and aluminum alloy. The second wires are constituted by metal wires different from the first wires and have a relative permeability of 4.0 or less. By setting the relative permeability of the constituent wires of the conductor portion to 4.0 or less, it is possible to suppress temperature rises caused by eddy current loses due to external magnetic fields, thus alleviating degradation of the insulation layer and poor insulation.

    摘要: A steel wire of pearlite structure containing 0.8-1.0 mass % of C and 0.8-1.5 mass % of Si is disclosed. In the cross section of the steel wire the average hardness in a region up to 100 &mgr;m from the surface thereof is at least 50 higher that that in a deeper region based on micro-Vickers hardness. The steel wire is manufactured by working a wire rod having the abovementioned chemical composition through shaving, patenting and drawing processes, then strain-relief annealing the resultant wire, and thereafter subjecting the thus annealed wire to a short peening process. The steel wire can be produced through a drawing process without applying a quenching and tempering process, and are superior in heat resistance and fatigue strength.

    摘要: The present invention relates to a sintered ceramic wire.Ceramic materials, such as A1N, Si.sub.3 N.sub.4 and Al.sub.2 O.sub.3, have various superior characteristics including heat-resistance, and sintered ceramic materials have been of interest as superconducting materials of high critical temperatures.However, various disadvantages are involved in the formation of the sintered ceramic materials as thin wires, and in the practical use thereof.The present invention elminates such disadvantages to provide a thin and long sintered ceramic wire having sufficient strength and toughness to avoid breakage.A sintered wire is made by placing powders of metal oxides, precursors of the desired sintered material, having oxidation potentials less than that of copper, in a tube of a high temperature oxidation-resistant metal. This product is worked to its final size and a sintering step is performed. The method is satisfactory for manufacture of ceramic superconductors.
