摘要： PURPOSE:To move permanent magnets for carrying by connecting a low-and room-temperature sections to each other through a connecting thin tube fitted to a removable perforated flange which blocks the opening of the low- temperature section and cooling the low-temperature section with a cooling device, and then, moving high-temperature superconducting bodies by moving a carrier by means of a shaft in the connecting thin tube. CONSTITUTION:A vacuum vessel 1 and adiabatic vacuum vessel 2 are separated from each other by a partition 3 and a hollow connecting thin tube 22 is passed through the partition 3. The tube 22 makes a hollow low-temperature division 4 communcate with a room-temperature division through a removable perforated flange 4C. A cooling vessel 4 is cooled with the coolant of a cooling device 5. A carrier 7 in the cooling vessel 4 is moved forward or backward by means of a ball screw 23 by rotating a shaft 24 in the tube 22 by means of a driving motor 9 in the room-temperature division. As a result, superconducting bodies 8a and 8b fitted to a linear guide 25 move forward or backward and permanent magnets 16a and 16b for carrying in a heat-shield 18 are interlocked with each other in a non-contacting state. Therefore, the carrier 7 and a mover 14 can be accurately positioned and driven.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic levitation conveyance device with good cooling efficiency. SOLUTION: Baffle boards 41 , 42 are fitted at a cooling pipe 13 which is routed in a low temperature tank 11, a carrier 12 is cooled through cooling medium gas with which its inside is filled, and the baffle boards 41 , 42 are cooled directly by the cooling pipe 13 when high temperature superconductive conductors 81 , 82 fitted at the carrier 12 is made superconductive critical temperature or lower. The baffle boards 41 , 42 are cooled to the superconductive critical temperature or lower, therefore, heat is prevented from entering from a part where the driving force of a motor 24 for moving the carrier 12 is introduced into the low temperature tank 11 and from a place close to a device positioned at a conveyance destination, thus it is possible to improve cooling efficiency. It is desirable to fit a heat insulating material between the baffle boards 41 , 42 and the wall surface of the low temperature tank 11 for prevention of the cooling medium gas from circulating, thus improving cooling efficiency markedly.

摘要： PURPOSE:To enable high temperature super conductors to be disposed close to carrying permanent magnets, and thereby enhance magnetic levitation performance by arranging a heat shield in the inside of a vacuum container in such a way that the cooling section of a hollow cooling container and a carrying arm are enclosed by the shield. CONSTITUTION:When a plurality of carrying permanent magnets 39a and 39b are lowered down by means of a lifting mechanisms 40a and 40b while being faced to a plurality of high temperature super conductors 30a and 30b which are cooled at temperature less than a critical one for the super conductors, a heat shield 41 is arranged in the inside of a vacuum container 22 in such a way that the cooling section 24b of a hollow cooling container 24 and a carrying arm 37 are enclosed by the shield, there exists nothing but the wall of the hollow cooling container 24 between each high temperature super conductor 30a and 30b and each carrying permanent magnets 39a and 39b. This constitution thereby enables each high temperature super conductor 30a and 30b and each carrying permanent magnet 39a and 39b to come very close to each other, and also enables the levitation of the carrying permanent magnets 39a and 39b to be made low in height, and restraining force in the advancing and transverse directions can concurrently be made great, so that positioning can thereby be enhanced in accuracy.

摘要： PROBLEM TO BE SOLVED: To provide a moving piece and a magnetic levitation conveyance device which can move a high temperature superconductive conductor without cooling it down below superconductive critical temperature. SOLUTION: Before magnetic force is given to magnets 181 , 182 for conveyance fitted onto a moving piece 2 for a carrier 12 movably-mounted inside a low temperature tank 11 to magnetically-levitate the moving piece 2 and move the carrier 12, an axial error in the moving axial direction to be corrected is detected by rolling it on the low temperature tank through a rolling means formed at the moving piece 2 at the time of ature superconductive conductor requires no cooling down below superconductive critical temperature. By fitting a limit mechanism for limiting the rolling movement of the moving piece 2 in the longitudinal direction of the low temperature tank 11, it is possible to eliminate a danger of dropping it off from the top of the low temperature tank 11, thus providing much convenience.

摘要： PURPOSE:To facilitate the recovery of a carrying arm when it is fallen onto a cooler by mounting a pair of parallel guide rails on a place on a hollow cooling vessel corresponding to the moving line of a high temperature superconductor. CONSTITUTION:On a place on a hollow cooling vessel 22 corresponding to the moving line of a plurality of high temperature superconductors 27a, 27b moved together with a carrier 16, a pair of parallel guide rails 1a, 1b are mounted. When the temperature of the two high temperature superconductors is raised during the horizontal movement of a carrying arm 34 to weaken or lose magnetic repelling force, the carrying arm 34 is fallen onto the hollow cooling vessel 2, but no lateral slippage is caused because the carrying arm 34 is fallen between the parallel guide rails 1a, 1b. The high temperature superconductors 27a, 27b are moved together with the carrier 26, and the fallen carrying arm 34 is moved to the position of raising and lowering mechanisms 27a, 27b together with carrying permanent magnets 36a, 36b, and brought up by the raising and lowering mechanisms.
