    摘要： A piezoelectric composite material having excellent piezoelectric property and workability, which is prepared by compounding in a specific mixing ratio a ferroelectric ceramic powder comprising microcrystals having uniform size and virtually a single domain and a polymer. The ceramic powder is obtained by preparing a ceramic having a desired composition by causing the appropriate mixture of starting powders to undergo a solid phase reaction, grinding the reaction product, annealing the resulting powder under heat and optionally chemically etching it.

    摘要： A method of manufacturing an Al-stabilized superconductor is disclosed. The method comprises combining into a composite a thin elongated Al member and a superconductive wire. The Al member is preferably comprised of high purity Al having a purity of not less than 99.9% and the superconductive wire is comprised of copper or a copper alloy matrix. The method produces a composite with strong adhesion between the Al member and the superconductive wire even under adverse conditions. Further, the method can be easily and quickly carried out.

    摘要： A method for producing an aluminum-stabilized superconducting wire is dislcosed herein, which comprises alternately winding superconducting elementary wires and high purity wires around a core, such as an electrically insulated copper wire core, impregnating the entire wire arrangement with solder to bind the wires together and subsequently forming or drawing the wire arrangement to increase the adhesion between the wires. In another embodiment, the thus-impregnated wire arrangement is subjected to a heat treatment to recover the residual resistance ratio of the aluminum. The impregnated wire arrangement is characterized by having a high mechanical toughness and improved electrical contact for greater electrical stability.

    摘要： The invention relates an Al-stabilized superconducting wire for use in a superconducting magnet used in a charging magnetic field, such as a pulse magnet and the like, and particularly to an Al-stabilized superconducting wire having the properties of reduced size and light weight, high current density, high stability, low AC loss, etc., and a method for producing the same. The said Al-stabilized superconducting wire has a core chosen from a superconducting elementary wire, an electrically insulated Cu or a Cu alloy, or a nonmagnetic metal or alloys thereof, and wherein the superconducting elementary wires and high purity Al wires are alternately stranded around said core. The stranded cable is bonded by impregnating it with solder, or further by subjecting it to a reduction process and heat treatment thereby making it possible to obtain an aluminum stabilized superconducting wire having said high properties.
