摘要： A method of manufacturing a superconductor is carried out by first preparing a material composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7. This material is heated/molten in a platinum crucible. A melt thus obtained is drawn out from a high-temperature frame provided above the platinum crucible and heated to a temperature exceeding the melting point of the material. The melt thus drawn out is cooled by natural standing, to be solidified. As the result, an elongated superconductor composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7 can be obtained. This superconductor enters a superconductive state at 90 K.

摘要： A method of manufacturing a superconducting wire is carried out by first preparing a material being composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7. This material is melted in a platinum crucible. A melt thus obtained is drawn out from a hole provided on the bottom wall of the crucible to be linearly discharged. The linearly discharged melt is cooled and solidified. A cooling/solidifying space for such a step is set at a temperature less by about 10.degree. C. than the solidifying point of the material, and a slow-cooling zone is provided next to the cooling/solidifying space. This slow-cooling zone is provided to be at a relatively high temperature in a portion closer to the hole while having a temperature gradient along a direction for linearly discharging the melt. A superconducting wire being composed of Y.sub.1 Ba.sub.2 Cu.sub.3 O.sub.7 is obtained. This superconducting wire superconducts at 85K.

摘要： A method of manufacturing an improved conductor wire, especially for use as wiring in audio/video devices is disclosed. The conductor consists of copper having a high purity of at least 99.9 wt. %. High purity copper starting material is formed as a rod which is then heat treated at a temperature in the range of 400.degree. C. to 700.degree. C. for 1 minute to 24 hours. The heat treated rod is then cold worked with a reduction in area of at least 65%. This method provides an electrical conductor wire which avoids irregularities of electron density and thereby eliminates phase differences in a high frequency signal, such as an audio or video signal, passing through the wire to obtain clear transmission and reproduction of an audio sound or video image. The method of the invention increases the residual resistance ratio of the conductor wire to at least 179 or by at least 20% as compared to a conventional conductor which is not heat treated according to the invention. Finally, in a quality control method, the expected audio and video transmission characteristics of a manufactured conductor wire can be evaluated by determining the residual resistance ratio of the conductor wire.

摘要： Strands of a copper alloy containing 0.2 to 10 percent by weight of Sn are braided to form a stranded wire for a wire conductor for a harness having a conductor sectional area of 0.03 to 0.3 mm.sup.2. After the braiding, preferably stranded wire is heat treated so that its tensile strength is maintained at a prescribed level. The wire conductor for a harness has a breaking strength which is equivalent to that of a conventional harness wire, and is hardly broken by an impact. The wire conductor maintains its straightness, and strand ends do not fray upon cutting.

摘要： A composite member suitable for a heat radiation member of a semiconductor element and a method of manufacturing the same are provided. This composite member is a composite of magnesium or a magnesium alloy and SiC, and it has porosity lower than 3%. This composite member can be manufactured by forming an oxide film on a surface of raw material SiC, arranging coated SiC having the oxide film formed in a cast, and infiltrating this coated SiC aggregate with a molten metal (magnesium or the magnesium alloy). The porosity of the composite member can be lowered by improving wettability between SiC and the molten metal by forming the oxide film. According to this manufacturing method, a composite member having excellent thermal characteristics such as a coefficient of thermal expansion not lower than 4 ppm/K and not higher than 10 ppm/K and thermal conductivity not lower than 180 W/m·K can be manufactured.
