Abstract
A superconductivity utilizing support mechanism comprises a superconductive coil and a ferromagnetic body. One of the ferromagnetic body, so constituted as to slide in a direction of a center axis of the superconductive coil, and the superconductive coil, so constituted as to slide in a direction of the center axis thereof, is floated and supported relative to the other by axial magnetic attraction caused by a center plane of the superconductive coil and a center plane of the ferromagnetic body moving apart from each other.
Claims3
A superconductivity utilizing support mechanism comprising:
- a superconductive coil;
- a ferromagnetic body;
- and
- an annular member that has a substantially U-shaped cross-section,
- the superconductive coil being arranged inside a U-shaped portion of the annular member,
- wherein the ferromagnetic body has a substantially ring shape or a substantially columnar shape, and is provided at its axially upper and lower ends and also at a position facing convex portions of the U-shaped portion of the annular member, with flange portions protruding radially outward, and
- one of the ferromagnetic body, so constituted as to slide in a direction of a center axis of the superconductive coil, and the superconductive coil, so constituted as to slide in a direction of the center axis thereof, being floated and supported relative to the other by axial magnetic attraction caused by a center plane of the superconductive coil and a center plane of the ferromagnetic body moving apart from each other.
