摘要： PURPOSE:To reduce a low order electromagnetic pulsating power for affecting adverse influence to a superconducting coil and to obtain a propulsion device for a magnetically levitated vehicle to be stably traveled by differentiating magnetomotive forces generated in inner and outer coils for constituting propulsion coils. CONSTITUTION:Reference numeral 2 denotes a propulsion coil, which is formed of two layers of an inner coil 2a and an outer coil 2b. The number of turns of an outer coil conductor 3b is increased more than that of an inner coil conductor 3a so that mutual inductances of the coils 2a, 2b and a superconducting coil 1 become substantially equal. With this structure, a secondary spacial harmonic magnetic field component in a conventional propelling device 10 which one layer of 3-phase coils is disposed, can be set to substantially zero, and further influence of 1.5-order electromagnetic pulsating power due to a 0.5-order spacial harmonic magnetic field caused by the difference of distances of the inner and outer coils to the coil 1 in the conventional device in which two layers of 3-phase coils are disposed, can be removed.

摘要： PURPOSE:To conduct stable travelling by installing superconducting coils for stabilization oppositely faced to both of a pair of upper and lower sidewall coils for levitation, which are null-flux connected mutually, onto a track sidewall on the ground side apart from a superconducting coil for collecting currents. CONSTITUTION:Upper-side sidewall levitation coils 4 and lower-side sidewall levitation coils 5 are connected in a null-flux manner on the inside of sideswalls 3 on both sides forming a track 2 on the ground side. A plurality of coils 6, 7 for collecting currents are disposed onto a car body 1 while being oppositely faced to the sidewall levitation coils 4 and 5 in the longitudinal direction. Superconducting coils 9 for stabilization are mounted on both side sections of the car body, and housed in a cryostat 10 together with the superconducting coils 6 for collecting currents. The superconducting coils 9 for stabilization are faced oppositely to the upper and lower sidewall levitation coils 4 and 5. Accordingly, a change in the vertical direction of the car body 1 is inhibited, thus carrying out stable travelling.

摘要： PROBLEM TO BE SOLVED: To obtain a cryogenic temperature tank having excellent reliability and heat insulating property by suppressing the generation of stress resulting from thermal contraction and thermal expansion and the generation of frictional heat resulting from vibration. SOLUTION: A lead-out tube 5 is supported to an outer tank by a supporting device 14. This supporting device 14 has the thermal shrinkage factor larger than that of the lead-out tube 5, and it is provided with a supporting member having a through hole of the diameter larger than the outside diameter of the lead out tube 5. The lead out tube 5 is fitted to the through hole in a loosely fixed manner at a normal temperature by the supporting member. At this point, a gap between the through hole and the lead out tube 5 is secured, and the relative displacement can be obtained between the supporting member and the lead out tube. Besides, when a cryogenic temperature is attained, the lead out tube 5 is firmly fixed by the thermal shrinkage factor of the supporting member due to the difference in thermal shrinkage factors, and the generation of frictional heat can be suppressed by the inhibition of the relative displacement between the supporting member and the lead out tube by vibration.

摘要： PROBLEM TO BE SOLVED: To assemble load supporting materials of inner vessels in less numbers, by providing the load supporting materials on a first line which connects the centers of two facing sides of four sides around a surface of an outer vessel which is parallel with a coil surface, and on a second line which connects the centers of other two facing sides. SOLUTION: Flexible load supporting materials 30 of an inner vessel 2 is provided on a first line 96 which connects each central part of two facing sides of four sides which construct a peripheral of a surface of an outer vessel 4 which is parallel with a coil surface 41, and on a second line 97 which connects each central part of other two facing sides. By the means in the case of the outer vessel 4 being deformed by bending, a position of the flexible load supporting materials 30 becomes to be a turning point of oscillation, and the flexible load supporting materials 30 does not conducts lateral oscillation. Therefore a deformation by bending of the outer vessel 4 is hardly conducted to the inner vessel 2. Therefore, the inner vessel 2 has an effect of suppressing heat generation caused by the deformation, without generating tortional deformation caused by tortional oscillation of the outer vessel 4.
