摘要： PROBLEM TO BE SOLVED: To operate a refrigerator very stably by stabilizing the flow rate of a refrigerant flowing in a JT circuit. SOLUTION: When a refrigerant after primary cooling in the refrigerator 20 is subjected to adiabatic free expansion for further cooling by the Joule- Thomson effect to produce a cryogenic temperature, a low temperature part effects only the expansion of the refrigerant by a primary pressure regulating valve 50, 60, 70, and flow regulation of the refrigerant is effected by a flow regulating valve 52 in a room temperature part.

摘要： PROBLEM TO BE SOLVED: To provide a material for supporting the load of an ultralow- temperature member and a load supporter which fulfill the load support of the ultralow-temperature member and the reduction of heat penetration at the same time, and by which load supporting member in optional form such as band shape or the like can be constituted in compact form, by preventing the immoderate transformation accompanying the thermal shrinkage of the ultralow-temperature member. SOLUTION: Fixing eyes upon that the directional change between the fulcrum points of the load supporting member 21 arising by thermal shrinkage is normally very little, and that the stress change of the load supporting member 21 arising in accordance with this change is also small, a support shaft 10 attached to ultralow-temperature member 7 and a support shaft 9 attached to a cryostat are provided with bushes 22 having convex surfaces 23 at both ends of a support material body 14, and the convex surfaces 23 are brought into contact with the surfaces of the support shafts 9 and 10, and the bush 22 turns in the direction orthogonal to the supporting shafts 9 and 10, thereby making them rockable.

摘要： PURPOSE:To minimize the movement of the tuner so as to improve the reliability and the life time of a cavity resonator by controlling the circulating flow rate of coolant basing on the temperature of the cavity body detected with a temperature detecting means. CONSTITUTION:The temperature of a cavity body 10 is detected with a thermometer 11 and compared with a preset temperature with a flow rate controller 12, and when the preset value is higher than the detected value the opening of a flow rate controlling valve 13 is increased depending on the temperature difference. On the other hand, when the preset value is lower than the detected value the opening of the flow rate controlling valve 13 is decreased depending on the temperature difference. Thereby the flow rate of pure water flowing in a cooling tube 5 is controlled by the said valve 13 so as that the temperature of the cavity body is kept nearly at the preset temperature. Thereby when adjusting the resonance frequency the movement of the tuner can be minimized to obtain an accelerating cavity resonator of high reliability and long life time.

摘要： PROBLEM TO BE SOLVED: To realize a small and low-cost refrigerator, in a refrigerator with a JT circuit. SOLUTION: When a refrigerant after primary cooling in the refrigerator 20 is subjected to adiabatic free expansion for further cooling by the Joule- Thomson effect to produce a cryogenic temperature, a high pressure in the Joule-Thomson circuit 30 is set not higher than a given pressure slightly higher than an atmospheric pressure, and a temperature at a second-stage cooler 32 disposed in the second stage 22 of the refrigerator 20 is set lower than a condensation temperature of the refrigerant depending on the high pressure in the JT circuit 30, so that the refrigerant is condensed in the second-stage cooler 32.

摘要： PROBLEM TO BE SOLVED: To reduce the amount of liquid helium used and to facilitate liquid level control by connecting an oxide superconducting current lead to an electrode of a superconducting system through a metallic superconducting wire having a curved portion and by immersing the curved portion into liquid helium while locating the curved portion lower than the connecting portion. SOLUTION: A metallic superconducting wire 3A has a U-shaped curved portion. An oxide superconducting current lead 5 is connected to a superconducting magnet electrode 2 through the wire 3A. The lowest liquid level 9 is the level of liquid helium required so that each of a superconducting magnet 1, the electrode 2 and the wire 3A comes in contact with the liquid helium at least partially. Therefore, the level 9 is located in the vicinity of the curved point of the U-shaped curved portion of the wire 3A.

摘要： PROBLEM TO BE SOLVED: To provide a cooling/heating plate for wafer chuck that can secure the minimum thickness required for cooling or heating characteristics and stiffness, and at the same time the required flow rate of a heat medium. SOLUTION: In this cooling/heating plate for wafer chuck, two heat exchanger plates having a plurality of channels radially formed from a center-section side to an outer-periphery one are mutually overlapped. On a side-wall plate 12, an outer- periphery channel 21 of the upper-side heat transfer plate, and heat medium gateways 16b and 16a for upper and lower sides are provided in parallel so that each of the heat medium gateways communicates with the outer-periphery channel of a lower-side heat transfer plate. Notches 80b and 80a are provided in a region corresponding to the heat medium gateway for the upper side in a partition board member 80 for partitioning the upper- and lower-side outer-periphery channels, and a region corresponding to the heat medium gateway for the lower side. At the edge section of the notch 80a, the upper-side outer-periphery channel 21 and an upper-side partition wall 81b for partitioning are provided. Then, at the edge section of the notch 80b, the lower-side outer-periphery channel and a lower-side partition wall 81a for partitioning are provided, thus setting the diameter of the heat medium gateway for the upper and lower sides larger than a dimension determined according to the thickness of the heat transfer plate.
