IPC: F25B45/00
Filed: 1992-09-18
Abstract: PURPOSE:To recover water-free refrigerant only and thus prevent the occurrence of the trouble caused by the water inclusion by a method wherein CFC refrigerant is liquefied and recovered, this liquid refrigerant is supercooled with brine for separation into frozen water and the liquid refrigerant and the refrigerant thus separated is taken out as a regenerative one. CONSTITUTION:Refrigerant gas is recovered from a refrigerating cycle 1 by and into a refrigerant recovering device 2 to compress, cool and condense the refrigerant gas and the resulting liquid refrigerant is thereafter collected in a liquid receiver 3 to remove oil, rust and other contaminants therefrom. The refrigerant thus decontaminated is supplied from the liquid receiver 3 through a refrigerant pipe 4 into a brine heat exchanger 5 and then supercooled by the brine in a chiller 6. At that time, the water existing in the refrigerant as vapor is frozen on the inner wall of the brine heat exchanger 5 and separated from the refrigerant. On the other hand, the regenerative refrigerant deprived of oil, rust, water and other contaminants is sucked out by a refrigerant pump 7 and sent back into the liquid receiver 2 for reuse or filled in a drum 8 for shipment. By this regeneration method, only the water-free refrigerant is recovered.

Title: Gas proportional counter for x-rays
Inventor: FUNABASHI MANABU
IPC: H01J47/06
Filed: 1987-10-05
Abstract: PURPOSE:To enable one counter to detect X-rays in the wide wavelength range at the optimum efficiency together with high wavelength selection capability by sequentially changing effective volume or pressure of gas for detection according to the wavelength of the X-rays to be detected. CONSTITUTION:Efficiency of detecting X-rays has dependency on wavelength so that a change of detection efficiency due to wavelength can be supplemented by changing an absorption factor of X-rays. The absorption factor of X-rays changes according to density of the gas for detection and route length of X-rays. While X-rays being incident from the window 9 of a gas proportional counter for X-rays pass inside the counter chamber 5, a collector 6 detects electrons ionized from gas. The gas proportional counter is formed of an outer pipe 1 and a slidable inner tube 2 being constituted so as to vary length of an X-ray route, or so that density of gas to be supplied from a tube chamber 5 may be variably adjusted. Thereby, one counter can be used by adjustment adapted to wavelength of the X-rays to be detected.
