摘要： A process for producing an oxide superconductor, comprising putting a formed body of raw material powders for forming an oxide superconductor on silver or silver oxide within a pan which does not melt at the melting point of silver, heating the pan to a temperature higher than the melting point of silver to bring the formed body to a semi-molten state with the formed body being floated on molten silver, cooling the pan and taking the formed body out of the re-solidified silver. This process enables a large bulk material having a diameter of 10 cm or more to be produced without occurrence of cracking.

摘要： A rotary body used in an energy storage device and capable of storing a large amount of external energy is provided in an energy storage device that stores external energy as the energy of the rotary motion of the rotary body for which the frictional resistance of the bearing parts has been reduced to a high degree using the fishing effect of superconductivity. The rotary body is used in an energy storage device capable of storing energy by rotating the rotary body for which the frictional resistance of the bearing parts having floating support that makes use of the fishing effect of superconductivity has been made very small. The rotary body is made of CFRP, and the required compressive stress is applied to it in the direction opposite to the centrifugal force of the rotary body when rotating. The rotary body has a bar-like structure elongated in the direction of the centrifugal force when the rotary body rotates.

摘要： A superconduction bearing is provided in which the load capacity and rigidity of a rotary member are improved, run-out of the rotary member is prevented to support the rotary member in a stable, non-contacting manner, and manufacturing cost is reduced. The superconduction bearing includes a rotary member and a disk formed on the rotary member. The disk has permanent magnets provided thereon. The permanent magnets are magnetized to have opposite poles on top and bottom sides thereof. A permanent magnet section is thus formed by the disk and the permanent magnets. Superconductors are concentrically provided for rotatably supporting the rotary member. The permanent magnet section and the superconductor section are positioned opposite to each other. The width and thickness of the permanent magnets are set to 5 to 10 times the distance between the permanent magnet section and the superconductor section.
