摘要： PURPOSE: To produce a superconductor having good conductivity in its circumferential and axial directions by melting a metal oxide used as a superconductor material and forming the superconductor having crystal axes each of which is directed toward the center of the superconductor in the radial direction through using a specific means. CONSTITUTION: In this production, metal oxide (e.g. YBa2 Cu3 Ox ) used as a material for a superconductor 1 is melted and then, plural seed crystals 2 (e.g. MgO) are placed on the periphery of the molten metal oxide so that each of the crystal axes of the seed crystals 2 is directed toward the center of the molten metal oxide in the radial direction and thereafter, cooled and solidified to form the superconductor 1 having crystal axes each of which is directed toward the center of the superconductor 1 in the radial direction. That is, when the seed crystals 2 are present, a crystal of the superconductor 1 is formed in the direction corresponding to the crystal axis of each of the seed crystals 2 and the crystal grows into a crystal oriented to the same direction as this direction in the peripheral part of each of the seed crystals 2 to form the superconductor 1 having good conductivity in both of two directions which orthogonally intersect each of the crystal axes.

摘要： PURPOSE: To provide a magnetic repulsion device which increases a repulsive force as compared with that in conventional cases and whose performance can be enhanced. CONSTITUTION: A magnet 12a is attached to a holder 13, and superconductors 12 are arranged on both sides of the magnet 12a so as to be fixed to the holder 13 by retention plates 14. In addition, a single-body magnet 12b is arranged and installed in a relative position to the magnet 12a. When the magnet 12b is brought close to the magnet 12a, a repulsive force due to a magnetic flux 15 is generated. However, since the upper part and the lower part of the magnetic flux 15 are surrounded by the magnets 12a, 12b and both sides are surrounded by the superconductors 11, a leakage flux becomes extremely small, and the repulsive force is increased.

摘要： PURPOSE: To reduce iron loss of a generator/motor at the time of waiting and storing energy. CONSTITUTION: A generator/motor 20 to be combined with a rotor 21 has a stator 23 shiftable to a position Y separated from a position X where the stator 23 is combined with the rotor 21. A mechanism 36 shifts the stator 23 from the position X to the position Y under the waiting state of a flywheel and the energy storing state. Since the stator 23 is shifted from the position X where the stator 23 is combined with the rotor 21 to the separated position Y under the waiting state of the flywheel 4 and the energy storing state, iron loss to be generated between the rotor 21 and the stator 23 can be reduced.

摘要： PURPOSE:To restrict the deflection and obtain a conductor having high rigidity by housing a superconductive wire in an inner tube having a polygonal cross section, and covering the inner tube with an outer tube. CONSTITUTION:A superconductive wire 3 is housed in an inner tube 21 having a hexagonal cross section, and the inner tube 21 is covered with an outer tube 23. The inside of the inner tube 21 works as a main flow passage 22 of the refrigerant. Clearances between the inclined surfaces 21c of the inner tube 21 and the inner surface of corner parts of the outer tube 23 work as auxiliary flow passages 24, and these auxiliary flow passages 24 are communicated with the main flow passage 22 through communicating ports 25 provided in the inclined surfaces 21c. When a coil is wound, a load is transmitted smoothly between conductors to restrict deflection and a compact conductor having high rigidity is obtained.

摘要： PURPOSE:To make it high in collapsing pressure and possible for lightweightiness and reduction in manufacturing cost as well as to enable it to be safely used by making the shell plate of a cylindrical barrel of an external pressure-proofing cylindrical shell to be used in the underwater or the like, where depth is large enough, so as to be projectingly bulged outward between both ring reinforced members separating. CONSTITUTION:An external pressure-proofing cylindrical shell 1 receiving uniform pressure P from the outside has a cylindrical barrel 4 and each end plate 3 at both ends, and the shell plate of the cylindrical barrel 4 is projectingly bulged outward as expandedly shown in an A part, between frames 2 at a constant interval mutually in direction of the central line of the external pressure-proofing cylindrical shell 1. With this constitution, collapsing force is increased, as compared with the case that a shell plate part of the barrel 4 is a simple cylindrical form, such an external pressure-proofing cylindrical shell as in structure high in pressure-proof strength is made manufacturable in spite of using the same quantity of materials, thus this external pressure- proofing cylindrical shell 1 can be yet more safely used. Therefore diving can be done up to the depth of water.

摘要： PURPOSE:To reduce tension residual stress, and to prevent stress corrosion cracking, by applying local external pressure onto several place of the outside circumferential surface of a tubular vessel, moving it in order along the outside circumferential surface, and causing plastic deformation by low pressure. CONSTITUTION:In several places of a tubular vessel 1, an external pressure 2 is applied toward the inside from the outside. Subsequently, the external pressure 2 is removed, the vessel is rotated by some angle, and the external pressure 2 is applied again. This operation is repeated in order, and to the whole outside circumferential surface of the vessel 1, the external pressure 2 is applied. In this way, plastic deformation is generated under the low pressure, tension residual stress is reduced, and stress corrosion cracking is prevented.

摘要： PURPOSE: To provide a cooler and a cooling method for a generator-motor used for a power storage device which stores power, making use of the torque of the flywheel supported by a high temperature superconductive magnetic bearing. CONSTITUTION: A generator-motor 6 is cooled by introducing the nitrogen gas at a very low temperature made of gasified liquid nitrogen for cooling the high temperature superconductive magnetic bearing 12 supporting a flywheel 8 into inside of the stator 3 of the generator-motor 6 and onto the surface of the rotor 2 and the stator 3. Hereby, the generator-motor 6 can be cooled efficiently with a small quantity of nitrogen gas, and also efficient power storage can be performed without high vacuum within the power storage being marred. Furthermore, more efficient power storage can be performed, keeping the inside of the power storage always in high vacuum, by discharging the nitrogen gas having cooled the generator-motor 6 to outside of the air with a collector.
