摘要： PROBLEM TO BE SOLVED: To improve durability and elongate life of a flexible tube by regulating harmful displacement of the flexible tube caused by harmful vibration, etc. SOLUTION: Two apparatuses are connected by using a flexible tube 2 which is a bellows having such a structure as alternatingly continuing crown parts 20a and valley parts 20c. A regulating member 3 composed of a cord material is tensioned along the longitudinal direction of the flexible tube 2. When the flexible tube 2 is subjected to harmful displacement in the arrow Y1 direction caused by harmful vibration, etc., the tensile force of the regulating member 3 is increased.

摘要： PURPOSE: To eliminate an impeller type pump, which may make a plimary cause of friction and the like. CONSTITUTION: When a heat source 12 is operated to generate heat and evaporate the liquid refrigerant of an auxiliary refrigerant tank 3 under a condition that pressure balance valve 4 and a supplying value 5 are closed, the gas pressure of a gas phase unit 3b is increased and the liquid refrigerant in the auxiliary refrigerant tank 3 is sen into conduits 6, 8 to cool a part to be cooled or a shield plate 11 and, thereafter, is returned into a refrigerant main tank 10. When the pressure valance value 4 and the supplying valve 5 are opened, the liquid refrigerant in the refrigerant main tank 10 is supplemented into the auxiliary refrigerant tank 3.

摘要： PURPOSE:To reduce an occupying space of a main freezer and make a small-sized freezer by a method wherein a compression space, a radiator, a hold over, a heat exchanger and an expansion space are arranged substantially on the same axis. CONSTITUTION:Working gas compressed in a compression spacing 101 is cooled by freezed state generated in the second expansion spacing 209 of a subfreezer 200 when the working gas passes through a radiator 102, the gas passes through a hold over 103, is cooled to a lower temperature, passes through a heat exchanger 104, flows into an expansion spacing 105, is isothermally expanded under an upward movement of a head 109 to generate a freezed state of about 4.2k. For example, the working gas in an expansion spacing 105 passes through the heat exchanger 104 under a downward movement of the head 109. At this time, herium vapor in a tank 103 passes through a pipe 130 and further passes through the inside part of the heat exchanger 104. The herium vapor is cooled by the working gas of about 4.2K to become liquid, the liquid passes through a pipe 129 and is accumulated in a liquid phase part 131a of a tank 131. The working gas passes through the heat exchanger 104 passes in sequence through the hold over 103, and a radiator 102, its temperature is increased and then working gas returns to the compression spacing 101 so as to complete one cycle.

摘要： PURPOSE:To improve an air-tightness and a reliability by a method wherein a large diameter part slidably contacting with a compression piston at its inner side and a small diameter part slidably contacting with a rod fixed to the compression piston at its inner side are provided. CONSTITUTION:A compression cylinder 108 is provided with a small diameter part 108b slidably contacting with a rod 111 connected to a compression piston 109 at its inner side. The small diameter part 108b is sufficiently smaller than a large diameter part 108a. Working gas compressed in a compression spacing 101 is cooled by a freezed state generated in the second expansion spacing 209 of a sub-freezer 200 when the gas passes through a radiator 102. The working gas passes through a hold over 103, is cooled to a further low temperature, passes through a heat exchanger 104, flows into an expansion spacing 105, isothermally expanded through a downward movement of a head 109 so as to generate a freezed state of about 4.2k. The working gas in the expansion spacing 105 passes through the heat exchanger 104. At this time, herium vapor in the tank 103 passes through a pipe 130, flows into the heat exchanger 104, cooled by the working gas of 4.2k passing in the heat exchanger 104 to become liquid, flows in a pipe 129 and then the liquid is accumulated at a liquid phase part 131a of the tank 131.
