摘要： PROBLEM TO BE SOLVED: To provide an Nb3 Al compound superconducting conductor having an outer matrix satisfactorily joined to a stabilizing material without leaving any gaps on their interface, and a manufacturing method for the same. SOLUTION: A molded body with a hexagonal cross-section is made by forming an Nb coating 5 and a Cu coating 6 around a laminated body 1, thereafter the Cu coating is peeled off and removed to make a single wire 8. Next, a plurality of such single wires are packed into an Nb tube 9, a Cu-Ni alloy tube 10 is formed on the Nb tube 9, then it is area-reducingly worked, and the alloy tube 10 is peeled off to form a multi-wire 12 having an outer matrix 9', Then, an Nb-Al supersaturated solid solution is produced on a portion of the laminated body 1. In a cooling treatment at this time, Ga is used as a coolant. A stabilizing material 13 is formed on a surface of the outer matrix 9', then a re-heating treatment is performed for separating out an Nb3 Al phase from the Nb-Al supersaturated solid solution, or area-reducing work is performed prior to the re-heating treatment, whereby an Nb3 Al compound superconducting conductor is manufactured.

摘要： PROBLEM TO BE SOLVED: To ensure high critical current characteristics by constituting a superconductive cable with a superconductive part of Nb3Al-based compound; an outside matrix formed outside the superconductive part; a stabilizing material positioned inside the matrix; and a barrier material for separating the superconductive part from the stabilizing material. SOLUTION: A superconductive cable is manufactured in such a way that a plurality of single wire materials 6 obtained in a specified process are bundled, a Nb cover 16 forming an outside matrix and a Cu alloy cover 17 are extruded onto the wire bundle, wire drawing is conducted with a die to a specified size, the Cu alloy cover 16 is removed to obtain a multiple wire material 18 having many single wire materials 6. A stabilizing material 19 and a barrier material 20 are positioned in the specified arrangement inside the Nb cover 16 forming the outside matrix. The stabilizing material 19 and the barrier material 20 are previously combined with the single wire materials 6 before the Nb cover 16 is formed, and thereby the barrier material 20 separates the single wire materials 6 from the stabilizing material 19.

摘要： PROBLEM TO BE SOLVED: To provide a composite-type heat sink with a good heat radiation ability and a production method thereof at a low cost. SOLUTION: An aluminum wire 2 becomes an aluminum 15 due to plastic deformation caused by a contact frictional force between an outside circumferential groove 13 of a rotating wheel 12 and the aluminum (Step 102). An extrusion pressure is generated by holding the aluminum 15 against a checking protrusion 16 (Step 103), and is pressed fit to a material collection chamber 17 located in front of a checking protrusion 16 (Step 104). In the material collection chamber 17, a nipple 18 and a die 19 are arranged facing each other and a copper strip 3 is introduced from the nipple 18 (Step 114). The aluminum 15 pressed fit is jointed with the copper strip 3, extruded through a die 19 with a fin-shaped hole, and a heat sink 20 is produced (Step 105) and cooled by a water cooling device 11 (Step 106).

摘要： PROBLEM TO BE SOLVED: To hold high conductivity and superior mechanical strength so as to easily obtain a high magnetic field by composing a high strength and high magnetic field conductive material layer of a Ta/Cu dispersed reinforced complex that is a mixture of Ta powder and Cu powder. SOLUTION: An industrial pure Ta sheet and an industrial oxygen free Cu sheet are laminated to form two layers, the laminate is closely wound on an industrial oxygen free Cu core material 1, they are inserted into an industrial oxygen free Cu pipe, and extrusion processing or extension wire processing is applied. A single-wire Ta/Cu dispersed reinforced laminate complex is obtained. In this single wire Ta/Cu dispersed reinforced laminate complex, a Ta/Cu dispersed reinforced laminate complex layer 2 is 90 Vol.%, and a Cu cover layer 3 is 10 Vol.%. Next, this single wire Ta/Cu dispersed reinforced laminate layer complex forms a single hexagonal Ta/Cu dispersed reinforced laminate complex through a hexagonal dice.
