Abstract: PURPOSE: A method for economically fabricating a high temperature superconductivity epitaxial thick layer by using a partial meltage technique is provided. CONSTITUTION: In the method, powdered materials of a superconductor are mixed with organic materials and then coated on a single crystalline substrate to form the superconductivity epitaxial thick layer. A screen print or a dip process is preferably used for coating of the mixed materials. The powdered materials use a mixture of an yttrium barium copper oxide, a barium copper oxide, and an oxidized copper. The substrate uses a magnesium oxide, a strontium titanium oxide, or a lanthanum aluminum oxide. The coated organic materials are volatilized at a medium temperature, for example 500 deg.C, and then the substrate is rapidly heated to 1050 deg.C or more to partially melt the coated superconductivity thick layer. Thereafter, the partially melted superconductivity thick layer slowly cools down for epitaxial crystallization of the superconductivity thick layer.

Abstract: PURPOSE: An ice-storage cooling system using a high-efficiency latent heat member is provided to decrease extra electric power consumptions by reducing a temperature difference, which is needed for a freezing machine so the temperature difference for making ice is lower. CONSTITUTION: An ice-storage cooling system comprises a storage heat container, a freezing unit, an ice-making unit, and an ice-melting unit. The freezing unit cools heat-conduction fluids with refrigerants. The ice-making unit makes the ice by circulating the heat- conduction fluids inside the storage heat container. The ice-melting unit cools the frozen heat- conduction fluids with liquefying the ice. A latent heat member is heavy water(D20). A coil for heat-exchange inside the storage heat container circulates the heat conduction fluids by separating an inlet from an outlet.
