Filed: 1990-02-15
Abstract: PURPOSE:To obtain the oxide superconductor having high critical temp. and current density and low in magnetic field dependency by atomizing silver and the elements forming an oxide superconductor by heat treatment and then heat-treating the product. CONSTITUTION:A soln. of silver, the elements forming an oxide superconductor by heat treatment or their compds. is prepared. The soln. is atomized or converted into fine liq. droplets and then heat-treated. The effect is produced with a smaller amt. of silver than the conventional technique. For example, 0.01-0.5 mols, preferably 0.05-0.1 mols, of silver is used based on 1mol of other elements to be simultaneously used such as Ca. A superconductor powder having a uniform composition and in which silver is most finely dispersed is obtained by this method. Silver forms a pin in the oxide superconductor in superconduction and accelerates the conduction of the electric current. The silver forms a liq.-phase to enhance the density of the sintered body and increase the diffusion rate, and is considered to facilitate crystallization.

Abstract: PURPOSE:To improve accuracy in temperature control, to shorten a high- temperature keeping time and to alleviate embrittlement of a wound core, by performing a heat treatment step utilizing high frequency heating before winding and molding steps of an amorphous magnetic thin strip. CONSTITUTION:An amorphous magnetic thin strip 1 is wound around the outer surface of a roller 2. Thereafter the strip 1 is wound around a core 3 of a winding apparatus. Thus a wound core 4 is formed. A conductor 5 is inserted through the inside of the roller 2. When a high frequency current flows through the conductor 5, the roller 2 is magnetized in the circumferential direction, and a large eddy current is generated. The roller 2 is heated with the loss due to the eddy current, and the amorphous magnetic thin strip 1 is heated with said heat. Thus the accurate temperature control of the amorphous magnetic thin strip 1 can be performed. Since the heating time is very short, embrittlement of the wound core 4 is alleviated.
