    摘要： PROBLEM TO BE SOLVED: To obtain a low-priced NbTi superconducting multilayered plate having high Jc in a magnetic field of 3 Tesla or lower by eliminating the need for an Nb barrier. SOLUTION: This superconducting multilayered plate is formed by alternately laminating an NbTi alloy layer, containing Ti of 20 to 35 wt.% and a highly conductive metal layer, and its outermost layer is formed by a highly conductive metal. It is desirable that a grain boundary, which is formed by rolling, dislocation and a normal conductive phase be present on a NbTi layer. Also, the superconducting multilayered plate is formed by taking in and sealing the NbTi plate, containing the content, in a case formed by a highly conductive metal, and a hot rolling operation, a cold rolling operation, a heat treatment and a cold rolling operation are alternately repeated six or more times. Finally a heat treatment may be performed for a long time. As a result, the superconducting multilayered plate, having high Jc in a low magnetic field, can be obtained at low cost.

    摘要： PROBLEM TO BE SOLVED: To provide a magnetic shielding device, which can cool a magnetic shield at 90 K or lower, without needing a feed of a refrigerant and moreover, a has a closed-cycle-operation cooling system, which can tilt a magnetic shield (magnetic shielding space) at an arbitrary angle, is easy to handle, and can conduct a stable long-term continuous operation. SOLUTION: Thid device consists of a structure that a high-temperature superconductor magnetic shield 1 is installed in a vacuum container A with the torus-shaped section and the shield 1 is cooled in a superconducting state. In this case, the shield 1 consists of a structure such that a high-temperature superconductor thin layer is adhered to the inner peripheral surface of a magnetic shielding substrate formed into a cylindrical form and a cooling tube 13 is piped on the outer peripheral surface of the substrate in a Zigzagged shape in the axial direction of the substrate and is jointed to the substrate by welding. Moreover, the high-pressure piping 18 and low- pressure return piping 18 of a circulating gas cooling unit 19 using helium gas as a cooling circulating medium are made to communicate with the tube 13 and the above vacuum container A with the torus-shaped section is supported tiltably and movably by a tilting unit 8, provided on a tilting support truck 9 on both sides of the outside of the position of the center of gravity of the unit 8.

    摘要： PROBLEM TO BE SOLVED: To provide a superconducting integrated circuit which enables miniaturization and integration by increasing inductance per wiring unit length. SOLUTION: A superconducting integrated circuit has a structure provided with a soft magnetic material layer 13 which has a high permeability μ between interlayer insulating films 12 and 14. The structure enables the inductance per unit length of superconducting wiring 15 to be larger than that of the conventional circuit. Therefore, the total thickness T1 of the interlayer insulating films 12 and 14 and a soft magnetic material layer 13 is less than the thickness of the conventional interlayer insulating film. As a result, the width W1 of the superconducting wiring 15 is made narrower than that of the conventional circuit without being limited by a fringe factor KF, and the area occupied by the inductance is reduced. Therefore, the superconducting integrated circuit can be miniaturized compared with the conventional one, and the miniaturization of the element can shorten the wiring length and increase the operation speed.

    摘要： PROBLEM TO BE SOLVED: To provide a superconductive electrical energy transmission cable which needs only a narrow space, does not possibly interfere the generated magnetic field of superconductor magnets, and can be cooled and driven stably in a well balanced state. SOLUTION: A pair of superconductor bus bars 51 produced by housing a large number of conductive wires, which are superconductor wires, in metal pipes are housed inside a bus bar container 53 being surrounded with a heat shield 52, air-tightly connected with a coil container 22, and the inside of the bus bar container is kept vacuum 55. One ends of the superconductive bus bars 51 are electrically connected with connection leads of superconductive coils 20 through joints 21 and the other ends are connected with ambient temperature terminals 54 in a normal temperature space, and a coolant is introduced through a coolant supplying port 56 formed in the peripheral area of the joint 21 side, passed through metal pipes of the superconductive bus bars 51 to cool the inner conductive wires, and discharged outside through a coolant discharging port 57.
