    摘要: A bundle of carbon fibers each coated with copper or copper alloy is uniformly wound around a core rod under tension, and subjected to a hot press treatment in a non-oxidizing atmosphere. The core rod is then cut off along the surface of a plate formed by the hot-press to form a supporting electrode plate for a semiconductor device. The electrode plate thus fabricated incorporates therein carbon fibers in a spiral and concentric circular array around the core rod.

    摘要: A method of producing a vacuum circuit breaker, the breaker contacts of which are made of a cast alloy which contains copper or a copper alloy as its main component and, as the sub-component, a metal having a lower melting point and a higher vapor pressure than the main component and having a solubility limit to the main component at room temperature, e.g. lead, bismuth or an alloy of lead and bismuth, the sub-component being contained in excess of said solubility limit. The cast alloy is heated at a temperature not lower than 800.degree. C. but not so high as to cause a melting of the cast alloy, in a vacuum atmosphere which ranges in a pressure between 10.sup.-4 and 10.sup.-6 Torr, before the alloy is mounted as the breaker contacts in the vacuum circuit breaker. A plastic working may be imparted to the cast alloy before the mounting, by, for example, forging. Further, a second heat treatment may be effected on the cast alloy to which the plastic working has been imparted, under the same condition as the first heating. The heating is effective in promoting the spheroidization of the sub-component, and contributes to the prevention of exudation of sub-component to the surface of the breaker contact.

    摘要: A semiconductor device comprises a semiconductor substrate and at least one supporting electrode soldered to one surface of the semiconductor substrate. The supporting electrode is constituted by a composite body having fibers embedded in a matrix of an electrically conductive metal. The coefficient of the thermal expansion of the fibers is substantially equal to or smaller than that of the semiconductor substrate. The fiber is arrayed in an annular, circular, spiral or the like pattern at least in the surface portion of the composite body on which the composite body is bonded to the substrate.
