摘要： PROBLEM TO BE SOLVED: To avoid a space formed between the work and a jig due to difference in the coefft. of thermal expansion and to easily obtain an enough shielding effect by using a masking jig having an almost same coefft. of thermal expansion as that of the work to mask a part where formation of a film is not required, and forming a film only in a required part of the work. SOLUTION: For example, relating to a fiber joined part 26 having a structure of assembly of Si3 N4 divided members 20 on which a SiC fiber 22 is wound, a coating by CVD is necessary on the fiber joined part to prevent the SiC fiber 22 from loosening and to improve oxidation resistance. Relating to a part except the fiber joined part 26 it is required to be shield against CVD so as to prevent cracks or the like due to difference in the coefft. of thermal expansion between the divided members 20 and the CVD film. Therefore, a masking jig 28 comprising isotropic graphite having an almost same coefft. of thermal expansion as that of the divided members 20 (SiC) which constitute the joined part 24 is used to shield the part except the fiber joined part 26, and a SiC film is formed by CVD only in the fiber joined part 26.

摘要： PURPOSE: To increase the rate of filling of a ceramic matrix by firing a specified preform, impregnating a soln. of a precursor of ceramic and carrying out firing. CONSTITUTION: Nonoxide ceramic fibers are heated to 700-1,100 deg.C in the air to form oxide layers on the surfaces. After cooling, the fibers are heated to 1,200-1,600 deg.C in an inert gaseous atmosphere to obtain reinforcing fibers having oxide crystals on the surfaces. A soln. of a precursor of ceramic having 45-75wt.% concn. and contg. 5-30vol.% ceramic powder is impregnated into the reinforcing fibers to obtain prepreg. This prepreg is laminated and the resultant laminated body is heated at 100-400 deg.C under 2-10kg/cm pressure in an autoclave to melt the precursor as well as to remove the solvent. A preform is formed by solidifying the precursor melt by cooling, this preform is fired in inert gas and a soln. of a precursor of ceramic is impregnated into the fired preform which is further fired in an inert gaseous atmosphere after densification by heating and pressing in an inert gaseous atmosphere.

摘要： PURPOSE:To precisely control Jc and to expand the degree of freedom in the selection of a sheath material by scattering the deposition phases consisting of specific metal oxides and the decomposition reaction product of a base material phase in the base material phase in the Ba-contg. oxide superconductor formed by a melting method. CONSTITUTION:Additives consisting of the oxides of the metals selected from Si, Al, Zr, Mg, Ti, Sr, W, Co, and V and/or the powder to constitute the oxides of these metals are mixed at 1 to 50mol% with the base material powder consisting of the oxide superconductor contg. at least Ba to form the powder mixture. This powder mixture is packed into a copper sheath material and is heat treated at least at a partial melting temp. at which a part of the powder mixture melts after drawing or rolling. The base material powder partly melts and decomposes in the sheath material and the oxide superconductor consisting of the base material having no grain boundaries and the deposition phases scattering like 1 to 50vol.% island in the base material phase is obtd.

摘要： PURPOSE:To impartially improve the critical current density of an oxide superconductor regardless of its composition, etc., by applying a current to the superconductor. CONSTITUTION:A current regulated by a current regulator 13 is applied to a sample 10 consisting of an oxide superconductor having the composition of Y1Ba2Cu3Ox through a lead wire 12. The surface temp. of the sample 10 and the voltage between the terminals 16 and 16' of the sample 10, namely the resistance value of the sample 10, are detected. The results are plotted in the graph shown in the figure, and the point of change (inflection point) where the surface temp. and resistance value of the sample 10 are suddenly changed is obtained. By this method for reforming the oxide superconductor, the critical current density of the superconductor can be improved by applying an appropriate current to the superconductor.

摘要： PURPOSE:To improve workability in manufacturing a moulded matter by applying mixed powders of metal powders marked in extendability and sintering for composing superconductive material after moulding work. CONSTITUTION:At least one of metal elements to compose oxide superconductive material is used as metal powders. Instead of powders of cupric oxide which has conventionally been used, powders of copper having a high, or mixed powders with powders of yttrium added to them are used for composing powders. Plastic works such as hot extrusion II, rolling IV, drawing V, forming work VI, etc., are applied to these mixed powders, and sintering is then performed. By thus mixing metal powders in the mixed powders, the mixed powders are given with extendability as a whole, and workability is improved.
