PROCEDURE FOR PROJECTING A SUPER -CONDUCTIVENESS APPLICATION AND SUPER -CONDUCTIVE APPLICATION

摘要

A method of designing a superconductivity employing apparatus includes the steps of causing a magnetism generating disk-shaped floatable portion (4) to face a disk-shaped fixed portion (2) capable of exhibiting superconductivity with a gap (G) therebetween; initializing the fixed portion (2) to reach a superconducting state at a position where the floatable portion (4) is spaced away from the fixed portion (2) to such an extent that its magnetic field does not influence the fixed portion (2); and using properly first, second, and n-th approach characteristics (S1, S2, Sn) when a difference between an n-th approach characteristic (Sn) and the second characteristic (S2) is smaller than a difference between the first and second characteristics (S1, S2), where the first approach characteristic (S1) is a characteristic of a magnetic floating force obtained by allowing the floatable portion (4) to approach the fixed portion (2), the second approach characteristic (S2) is a characteristic of a magnetic floating force obtained by allowing the floatable portion (4) to approach the fixed portion (2) after the floatable portion (4) is allowed to recede from the fixed portion (2) to such an extent that its magnetic field does not influence the fixed portion (2), and the n-th approach characteristic is a characteristic of a magnetic floating force obtained by repeatedly carrying out the operations subsequent to the operation of the second approach characteristic (S2).
