摘要： PURPOSE:To lower the floor level necessary for operation so that the titled device may be installed in any room, by a method wherein the outside part is equipped with a projection in a detachable manner whereon a pipe which can perform a liquid He injection, and current leads, a refrigerator, and the like are provided. CONSTITUTION:An outside part of a vacuum container 7 is provided with a cylindrical projection 25, to which a guide 26 for inserting the liquid He injection pipe 11 and a guide 27 for inserting current leads are hermetically installed. The other outside part of the container 7 is provided with a cylindrical projection 28, to which a guide 30 for inserting a cryo-miniature refrigerator 29 is hermetically installed. Such a constitution makes the floor level L reduced in spite of the same level of lifting up an inserted matter. Also in the case of extracting the refrigerator 29 for repair, the lift-up level H' can be well treated in a range of the level L.

摘要： PURPOSE: To make it possible to stably operate a gas pump, by designing the gas pump in a double layer structure of heat insulating materials and accommodating a drive shaft, motor and bearings in an ordinary temperature area formed in a super low temperature liquefied gas, thereby to prevent a positional change due to thermal deformation among the drive shaft, housing and internal heat insulating layer.
CONSTITUTION: There is provided an inner heat insulating layer 14 inside of an outer heat insulating layer 13. In a housing 15 inside of the inner heat insulating layer 14, a drive shaft 2, motor 4 and bearings 24, 25 and 28 are accommodated. Further, a laminated heated insulator 23 is wound around an inside surface of the outer heat insulating layer 13 and an outside surface of the inner heat insulating layer 14. A flange 17 is provided with a vacuum exhaust pipe 40 so as to maintain a space between both the heat insulating layers under vacuum and thereby to effect heat insulation. With this arrangement, during introducing liquefied gas into a spacing between the drive shaft 2 and the inside of the housing 15, and another spacing between the outside of the housing 15 and the inner heat insulating layer 14 so as to cool each member, it is possible to independently adjust flow of the gas and uniformly cool the drive shaft 2, inside and outside of the housing 15 and the inner and outer heat insulating layers 14 and 13, thereby eliminating a positional change of each member due to thermal deformation and permitting a stable operation of the pump.

摘要： PURPOSE:To enhance air rectifying separation efficiency and Ar yield by cooling raw air with a gas from an expansion turbine and regulating the vol. of the gas supplied to the middle of the upper tower of a duplex rectifying tower in accordance with the vol. of product O2 and Ar drawn out, to raise the L/V value at the middle of the upper tower. CONSTITUTION:Raw air is compressed with compressor 12, cooled with change- over type heat exchanger 11, and divided into two parts. One part is supplied to the lower part of lower tower 1 of the duplex rectifying tower through heat exchanger 9. The other part is supplied to expansion turbine 7 through piping 131, and part or all of the gas from the outlet of turbine 7 is introduced into exchanger 9 through regulation valve 10 and piping 134, 135, and released into the air from piping 138. The residual gas is supplied to the middle of upper tower 3 through valve 10 and piping 133, and the vol. of the gas supplied is regulated in accordance with the vol. of product O2 and crude Ar drawn out.
