摘要： PROBLEM TO BE SOLVED: To provide an extremely low temperature refrigeration unit where a mist-like refrigerant is prevented from being discharged from a discharge port of the refrigerant and the mist-like refrigerant is prevented from being absorbed into a refrigeration system from a suction port even if liquid droplets occur due to a liquid sloshing phenomenon. SOLUTION: A vapor/liquid separator 16 is fitted to the suction port 15. Thus, the mist-like refrigerant is separated into a liquid and vapor by the vapor/liquid separator 16. Since a liquid-like refrigerant drops and remains in a liquid chamber 12 and only a gas-like refrigerant is sent to the refrigeration system, capability can be kept constant without increasing a load of the refrigeration system. When pressure loss becomes large, two or above suction ports can be formed by fitting the vapor/liquid separator 16. COPYRIGHT: (C)2004,JPO
摘要翻译：要解决的问题：为了提供一种极低温制冷装置，其中防止雾状制冷剂从制冷剂的排出口排出，并且防止雾状制冷剂被吸收到制冷系统中即使由于液体晃动现象而发生液滴，也是吸入口。解决方案：蒸汽/液体分离器16装配到吸入口15.因此，雾状制冷剂被气/液分离器16分离成液体和蒸汽。由于液体状制冷剂滴落并保持在液体室12中，只有气体状制冷剂被输送到制冷系统，能够在不增加制冷系统的负荷的情况下保持恒定。当压力损失变大时，可以通过安装气/液分离器16来形成两个或更多个吸入口。（C）2004，JPO

摘要： PURPOSE:To miniaturize a drive unit as a whole by installing a motion converting mechanism, converting reciprocation and rotation, between a turning shaft and reciprocating members set up between these two reciprocating members, and setting up a shift mechanism of this turning shaft and a load or driving source between these reciprocating members. CONSTITUTION:High pressure gas is supplied to each inside of cylinders 42, 43 via intake and exhaust valve mechanisms (unillustrated herein), and this gas is expanded, reciprocating pistons 44, 45, then this gas comes to low pressure and temperature and is exhausted out of the cylinder 44, 45. Each reciprocating motion of the pistons 44, 45 is converted into reciprocation of turning shaft 60 by a crank mechanism. Rotation of this turning shaft 60 is speeded up by a shaft mechanism consisting of a fixed internal gear 73, a rotating internal gear 72, a planetary gear 74, a carrier or the like, whereby a rotor 86 is rotated and driven, thus gas expansion energy is converted into electric energy. Rotational frequency of a motor is controlled by a control circuit attached to this motor 85, thus rotational speed of a gas expander is controlled. In this connection, the gas expander is driven by the motor 85.

摘要： PURPOSE:To prevent the decrease of the thermal efficiency of a refrigerator by opening a solenoid valve or a pneumatic valve for an excess load of energizing, degaussing, etc., and supplying high-pressure helium gas directly to a Joule- Thomson loop without intermediary of a flow throttle valve of the loop used at the time of normal operation. CONSTITUTION:A cryogenic refrigerating liquefying apparatus 7 has a cryogenic refrigerator 6 which has a helium compressor 3 for cooling a superconducting magnet 22 and a Joule-Thomson loop(JT) 4, and comprises a flow throttle valve 8 and a solenoid valve 9 having no flow throttling function in the high- pressure circuit 3 of the compressor 3. High-pressure gas compressed by the compressor 3 is pressure-reduced via the valve 8 in a normal operation, guided from the JT 4 to a helium tank 20, and evaporated helium gas of the tank 20 is returned from the JT 4 to the low-pressure circuit 1 of the compressor 3. The high-pressure gas which is not pressure-reduced is guided to the JT 4 via the valve 9 at the time of excess load of energizing, degaussing, etc.

摘要： PURPOSE:To improve the stability of a superconducting magnet which is subject to an external fluctuating magnetic field by suppressing the heat generation from a superconducting coil container so as to minimize the evaporation of superconducting coil cooling liquid helium. CONSTITUTION:A damper 7 formed of a material having a low electric resistance is fitted to the front external surface of a vacuum vessel and metallic layers having low emissivities are vapor-deposited on both the surface and rear of a shield plate 6 composed of a carbon fiber-reinforced material so as to reduce an induced current and, accordingly, to suppress the heat generation from a superconducting coil container. Therefore, the evaporation of superconducting coil cooling liquid helium can be reduced.

摘要： PURPOSE:To improve heat transfer efficiency and reduce the volume by winding alternately two pairs of thin plates and reticular sheets on a cylinder surface in multi-layers and bonding airtightly thin plates together at the beginning and the end of the plate in order to secure a plurality of pairs of spiral cross-sectional flow channels. CONSTITUTION:Thin plates A31 and B32, and a reticular sheets A41 and B42 are alternately spirally wound around a cylinder and they are bonded with a brazing material, etc. At a header section 1 a reticular mask section 5 is wound and solidified in one body with a soldering material, etc. In two kinds of fluids between which heat is exchanged, one enters the upper end of an inlet and outlet opening A61 and flows through the reticular sheet B42 and flows out from the upper end of the inlet and outlet opening B62. Each of the flow passages is divided by the thin plates A31 and B32, so that there is no chance that fluids get mixed together. It is possible to miniaturize the heat exchanger and improve its efficiency because the partition of the flow passage is very thin and each flow channel is divided into small channels and the distance between the flow channels can be made thereby small.

摘要： PROBLEM TO BE SOLVED: To provide a superconducting magnet power lead, which is capable of restraining heat from penetrating into a liquid helium system that contains a superconducting coil and feeding sufficient electric power to the superconducting coil. SOLUTION: A superconducting magnet power lead for feeding a current to 'a superconducting coil cooled down to liquid helium temperature of' via 'a radiation heat shielding unit, cooled down to liquid nitrogen temperature' in a superconducting magnet device is made to have a structure in which at least a part of the power lead located inside the radiation heat shielding unit is partially formed of an oxide high-temperature superconducting bulk body, whose critical temperature is higher than liquid nitrogen temperature. In this case, it is preferable that the bulk body be subjected to vacuum resin impregnating treatment to be improved in mechanical strength. When a braided lead is made to serve at least as a part of the magnet power lead except for the bulk body, stresses caused by the relative displacement of a device member is restrained from having adverse effects on the bulk body, so that the superconducting magnet power lead can be protected against damages.

摘要： PURPOSE: To obtain a magnetic levitation mechanism in which a vehicle is levitated perfectly without touching a ground facility at all while ensuring all functions of propulsion and guide by improving the arrangement of electri cally conductive plates opposing a magnet thereby generating a levitation force effectively. CONSTITUTION: The magnetic levitation mechanism comprises a pair of rotors 3-1, 3-2 arranged in a cross-section in the advancing direction of a mobile body, and electrically conductive plates 5-1, 5-2, 5-3 arranged continuously in the moving direction of the mobile body while being split such that the center of rotation of the rotors 3-1, 3-2 are located asymmetrically in a cross-section. The mobile is thrust by the difference of magnetic drag in the longitudinal direction between the rotors 3-1, 3-2 and when the mobile body is deviated perpendicularly to the advancing direction, a force for returning the mobile back to the center is generated.
