CRYOSTAT

摘要

PURPOSE:To prevent the rise of inner pressure within an inner container and reduce loss of coolant by a method wherein evaporated gas is discharged to the outside of an outer container at all times even if acceleration or deceleration is applied in any direction. CONSTITUTION:A first pipe 7a has an opening 11a located at one side of the upper part within an inner container 1, and a second pipe 7b has an opening 11b located at the other side of the upper part of the inner container 1. The first pipe 7a is communicated with a connecting pipe 7c via a bent part 12b locating in the upper part within the inner container 1 at the side of the opening 11b of the second pipe 7b, while the second pipe 7b is communicated with the connecting pipe 7c via a bent part 12a locating in the upper part within the inner container 1 at the side of the opening 11a of the first pipe 7a. The connecting pipe 7c is communicated with a pipe 7 for discharging gas via a connecting part 13 locating in gas phase.
