Abstract: PURPOSE:To form.realize an economic permanent current mode easily handled technically and economically by insulating a metal having a high resistance to perform a function as a heat source and integrally incorporating it in an oxide superconductor. CONSTITUTION:Powders of Bi2O3, PBO, SrCO3 and CuO are mixed at a molar ratio of 0.9:0.3:2:3. The mixture is heat treated at 800 deg.C for 24 hours, and then pulverized by a ball mill. Then, powder obtained by the pulverization of the mill is molded in a pellet by a press, again heat treated at 800 deg.C for 24 hours, then pulverized by a ball mill, and temporarily baked powder is obtained. This baked powder is filled in a press die for obtaining a molded form having a depth of 1cm, a length of 3cm and a width of 1cm. On the other hand, a high resistance metal obtained by winding an NiCr wire provided with an Al2O3 layer on its outer periphery in a coil state is extended at its end longitudinally substantially in the center to be disposed, and press molded.

Abstract: PURPOSE:To provide a close organization, or a good interface condition so as to improve easiness to flow of a superconductive current by applying either one of processes of drawing and rolling under a high temperature to a work which is processed. CONSTITUTION:Powders of an oxide superconductive component is filled in a tube of Ag, Au, Pt, Pd or their allay, and a process of forging, drawing or rolling is applied to the tube in which the powders of the oxide superconductive component are filled. In this case, at least one process of forging, drawing and rolling is performed under a room temperature, and at least one process of drawing and rolling is performed under a high temperature. Generation of pores, etc., in oxide superconductor can thus be eliminated easily, and oxide superconductive material having a close organization can be formed. By heat processing the alloy tube at its fusing point to 500 deg.C prior to filling the powders of the oxide superconductive component in it, crystal grains of the tube become larger, and a tube surface and the oxide superconductor have an interface having a good smoothness after the processes and the heat process.

Abstract: PURPOSE: To selectively record desired data through short time server-client communications by transferring all data and selecting data on a client device. CONSTITUTION: A data providing server 100 stores data that plural client information equipments 200 can use. The data providing server 100 sends all specified data. Then a client retrieves all the data and stores and displays only data that a user desires. The data providing server 100 sends the same data with the client to other clients when other data specify them. In many cases, other clients retrieves all the sent data under different conditions from the client and stores and displays only data that other users desire. Namely, the data providing server 1090 offers the same data to plural clients 200, but the storage and display of data are conducted matching with each user's desire on the sides of the clients 200.
