    摘要： A coaxial cable having an inner conductor including a very fine metal wire having a diameter of 120 .mu.m or below and a tensile strength of 100 kg/mm.sup.2 or above, and a plated noble metal layer coating the very fine metal wire, an insulating layer of an insulating material coating the inner conductor, an outer conductor coating the insulating layer, and a jacket coating the outer conductor. In forming the inner conductor, a metal wire is coated with a noble metal layer by plating, and then the metal wire coated with the noble metal layer is subjected to plastic working to reduce the diameter and to improve the structure of the noble metal layer, A high-frequency signal applied to the coaxial cable is transmitted through the noble metal layer of a satisfactory structure by skin effect without being disturbed. The very small diameter and very high tensile strength of the very fine metal wire of the inner conductor enables the coaxial cable to be formed in a very small diameter. Such performance and structure of the coaxial cable is advantageous in its application to electronic equipment including IC chip testers and high-speed electronic computer systems.

    摘要： An inspection probe which allows a plurality of such inspection probes to be arranged at a remarkably reduced pitch. The inspection probe comprises a very thin metal wire having a diameter of 120 .mu.m or less and so shaped as to have self resiliency, and a plated noble metal layer formed on a surface of the very thin wire. A probe pin head for the inspection of an electronic circuit board is constructed employing a plurality of such inspection probes. The inspection probes are secured to or embedded in a base made of a resin material. A process of producing the probe pin head is also disclosed.

    摘要： A high-strength, high-toughness steel with good workability is produced by working a steel containing 0.005-0.3% C and 0.3-2.5% Mn and optionally up to 1.5% Si, in the course of hot working thereof, at temperatures within the range of from the Ar.sub.3 point to 930.degree. C. or to 980.degree. C. (for a steel containing Nb, V, Ti and/or Zr) at an area reduction rate of at least 30%, and, in the course of cooling, rapidly cooling the steel in the ferrite phase precipitation temperature range when the ferrite phase has occupied 5-65% or 5-60% (for a steel with Si and/or Nb, V, Ti and/or Zr) of the steel, whereby a two-phase structure comprising ferrite and martensite is produced.

    摘要： A catheter guide wire which, despite its reduced diameter, exhibits improved strength and resistance to corrosion by body fluids and medicines. The catheter guide wire 10 is composed of a stainless steel core wire 11, a winding of a low carbon duplex structure steel wire 13 having a diameter smaller than 30 .mu.m and a tensile strength higher than 300 kgf/mm.sup.2, said winding covering the core wire such that tiers of the low carbon duplex structure steel wire run obliquely to the axis of the core wire 11 and have turns crossing each other, and a polyester resin film 15, thinner than 3 .mu.m, covering the low carbon duplex structure steel wire 13. The catheter is composed of a resin inner tube and a low carbon duplex structure steel wire 13 covered with a polyester resin film 15, which runs around the resin inner tube obliquely to the axis and crosses each other.
