Abstract: A fluid container that can prevent a container from being in contact with a heat source fluid and stably hold the heat source fluid, even if corrosive, in the container to perform heat recovery and the like. A first fluid and a second fluid are both allowed to flow into and out of a container body 10. The second fluid is supplied into the container body by a second fluid supply unit 30 to form a layer of the second fluid flowing down along an inner surface of the container body 10, causing the second fluid to be interposed between the first fluid and the inner surface of the container body. This eliminates deterioration of the container body due to corrosion of the container body by the fact that the first fluid has contact with the inner surface of the container body, as well as scale precipitation from the first fluid.

Abstract: A radial-gap type superconducting synchronous machine 1 is prepared which includes a rotor 20 having, on its peripheral side, a convex magnetic pole 21 which includes, at its distal end part, bulk superconductors 30. When viewed in the direction of the rotational axis C1 of the rotor 20, the magnetic pole center side of the bulk superconductors 30 is disposed nearer to a stator 10 than the magnetic pole end side of the bulk superconductors 30. A ferromagnet 28 is disposed on the rotational axis C1 side of the bulk superconductors 30. A magnetizing apparatus 100 is disposed outside the bulk superconductors 30 in the radial direction of the rotor 20. Magnetization of the bulk superconductors 30 is performed by directing magnetic flux lines from the magnetizing apparatus 100 toward the bulk superconductors 30.
