摘要： A superconductor has an aluminum area (4) at the center in the cross section of said conductor therein and copper-covered multifilamentary NbTi composite conductor (2) at the peripheral parts of the cross section formed there around. The cross-sectional area ratio of (Cu+Al)/NbTi is in the range of 0.5 to 3.0 and the cross-sectional area ratio of Al/Cu is in the range of 0.05 to 0.5. This superconductor is provided by a method comprising the first step of providing a superconductor-copper composite hollow body in which copper films are applied around the superconductors, the second step of area reducing said composite hollow body, the third step of heat treating said body, the fourth step of inserting an aluminum body into the hollow of said hollow body, the fifth step of subjecting the body to working such as drawing, and the sixth step of subjecting the body to working such as twisting, forming or the like, an additional area reduction being carried out, if necessary, subsequent to the third step. A superconducting coil is made using the superconductor, and the coil is used for a magnetically levitated vehicle or a nuclear magnetic resonance apparatus.

摘要： A track vehicle such as a Maglev train has a body (2,3) with superconducting coils (4) mounted thereon which superconducting coils (4) interact with vertically extending coils (10) on guideways (11) of a track (12) to generate a propulsive force. The vehicle runs on wheels (6) at low speeds but at higher speeds the superconducting coils (4) may interact with ground coils (9) to generate a lifting force. In order to reduce or eliminate stresses between the superconducting coils (4) and the vehicle body (2,3), the vehicle has one or more wings (1,100) of airfoil shape which generate lift. That lift may be sufficient to support the whole of the weight of the vehicle, enabling the ground coils (9) to be eliminated. Furthermore, the shape of the superconducting coils (4) may be changed so that they supply more energy to propulsive effects. Preferably the angle of incidence of the wing(s) (1,100) is variable, to permit the lift generated thereby to be varied. This variation in the angle of incidence may be controlled by a sensor (13) detecting the height of the body (2,3) above the track (12), to maintain that height constant.

摘要： In a process for manufacturing Nb₃Al phase (3) by a diffusion reaction of Nb₂Al phase (2) and Nb phase (1), a part of the Nb₂Al phase (2) is remained and dispersed in the Nb₃Al phase (3) homogeneously as for magnetic flux pinning centers for a high magnetic field. As for a method for dispersing the Nb₂Al phase (2) homogeneously, a Nb₃Al group superconducting precursory composition obtained by dispersing Nb particles (1) and Nb₂Al ultrafine particles (2) by a mechanical alloying method is used, and further, by a conventional method for generating Nb₃Al phase (3) by a diffusion reaction of Nb (1) and an aluminum alloy, the object of the present invention can be achieved.
In accordance with the present invention, a high magnetic field such as 20 T level can be generated economically with a compact apparatus, and a coil for generating a high magnetic field can be manufactured with only the Nb₃Al group superconductor. Therefore, the present invention is significantly effective for a nuclear fusion apparatus of a magnetic confinement type.
