摘要： PURPOSE:To provide a superconducting rotor which operates stably without causing quench by absorbing heat intruded from an inner rotor support into an inner rotor effectively and feeding cryogenic refrigerant through the refrigerant flow path in a superconducting field winding only in the inward radial direction at any part thereby maintaining a good heat transmission. CONSTITUTION:One or a plurality of holes or grooves, i.e., heat siphons 53, having openings only to an inner peripheral side cryogenic refrigerant tank 54 and not communicated with an outer peripheral cryogenic refrigerant tank 51 are provided in the radial direction, with the inner rotor support 17 on the side of winding support tube 9 and the axial end side of the winding support tube 9 being exposed between a superconducting field winding 8, the outer peripheral side cryogenic refrigerant tank 51 and the low temperature end 52 of the inner rotor support 17. Cryogenic refrigerant 5 flows continuously from the inner peripheral cryogenic refrigerant tank 54 into the holes to produce an opposing flow which collects its heat to the cryogenic refrigerant 5.

摘要： PURPOSE:To enable measurement of a correct liquid head by providing a heating control means to control a heating means so that a heating value is increased or decreased when the presence of a refrigerant is detected by a refrigerant detecting means. CONSTITUTION:An electric heater 16, a temperature measuring element 17 and a rod 18 for fixing them are inserted near a lower open end of a pressure pipe 15. A liquid level detection signal gives an electric output based on a temperature difference as obtained when the element 17 is and not immersed into a liquid surface of the refrigerant (superfluid helium) 2. Fine current flows to the element 17 from a current source 34, an input signal from the element 17 is amplified with an amplifier 35 to be compared with a reference voltage by a comparator 36 and a drive signal of a relay 37 is outputted according to a difference therebetween. A plurality of voltage outputs of a control voltage supply circuit of a heater power source 39 are change over with a switch section 38 of the relay 37 to control a heating value of the heater 16 based on the electric outputs.

摘要： PURPOSE:To make it possible to easily exchange a sample without disjointing a heat insulating vacuum vessel by opening one end of a sample chamber to the air side, and installing a sample introduction mechanism to seal this opening part airtightly from the air side and a gas charging mechanism. CONSTITUTION:After removing a cover, and setting a sample 12 to a sample supporter 11, and then wiring a measuring wire, the sample is inserted into a sample chamber 8, which is made air tight by fastening a clamp 9. Next, after exhausting the airinside the sample chamber into vacuum, helium gas is introduced by a gas charging mechanism 23 connected to a valve 23, and then the valve 13 is closed. A small cooler driving source is turned on, and with the temperature drop of the second stage the temperature of a copper block 7 is also lowered. Since noncondensing helium gas is charged into the sample chamber 8, the region at the same height as the copper block 7 is made almost uniform temperature, and the sample 12 is also made almost the same temperature as the copper block 7. For the exchange of the sample 12, in the condition that the temperature of the sample returned to the room temperature, the clamp 9 is removed and the inside of the sample 8 is made the atmospheric pressure, and the sample supporter 11 is pulled out, and the sample is exchanged.

摘要： PURPOSE:To improve economically efficiency and reliability by using a refrigerant respectively suited for a refrigerator generating cold, piping transporting the cold and a refrigerant storage tank generating a thermal load. CONSTITUTION:A superconducting rotary machine forms its rotor 1 from a double-hollow cylinder with its outer cylinder serving both for an electromagnetic shield and a vacuum vessel, and a refrigerant storage tank 2 and a superconducting field winding 3 are arranged inside the outer cylinder, rotating together with the rotor 1. An internal refrigerant 7 cools the before-described winding 3 with removed heat caught through a condensing heat exchanger 8 by a intermediate refrigerant 11, forcedly circulated by a pump 9 via a rotary coupler 10, and exchanged with an external refrigerant 13. An adjusting value 17 adjusts a quantity of the intermediate refrigerant 11, holding a heat exchanger 12 in its temperature to an optimum level. Here the winding 3, for instance when its power temperature is relatively low, the machine uses hydrogen for the internal refrigerant 7 and helium for the intermediate refrigerant 11. As the result, cooling efficiency can be improved because the optimum refrigerant can be used for each refrigerant.

摘要： PURPOSE:To previously check the improvement of the knowledge parameter value by displaying all rules that refer to the parameter when this parameter is changed. CONSTITUTION:An input/change procedure for knowledge parameter selects and instructs a frame name out of the function like the knowledge debug, etc., and displays the corresponding information on the frame name, the slot and the graph. Then a knowledge parameter is selected in a slot display column and the relevant rule referring the parameter is displayed. When many rules are available, all these rules can be confirmed with operations of the preceding and next pages. The parameter value is set when a point is picked up by a mouse on the graph.

摘要： PURPOSE:To improve the reflectance of a radiation shield and improve thermal insulating characteristics with a simple structure by a method wherein a surface of the radiation shield opposing to a low temperature side of a vacuum thermal insulation tank is made of a super-conductive material kept at its super-conductive condition and a surface of the radiation shield opposing to a hot temperature surface side is made of material having a high rate of reflection such as silver or aluminum and the like. CONSTITUTION:A super-conductive radiation shield 1 is composed of a thin film 5 of material having a high reflectance such as silver or aluminum and the like and of a super-conductive material 1a. The thin film side is faced to a hot temperature side and the superconductive material 1a. is faced to a low temperature side. Radiation heat radiated from a vacuum thermal insulation tank wall 2a is reflected, for its light having a wavelength shorter than that of a visible light, with a material 5 having a high reflectance. its light having a wave length longer than that of the above- described wavelength is fully reflected by the super-conductive radiation shield 1. As the applicable super-conductive material, for example, a cubic perovskite can be applied. This material reflects light up to a relative short wave length with a critical temperature of 250 kelvin.
