摘要： PROBLEM TO BE SOLVED: To reduce the amount of heat insulating material to be used and a space for a coldness accumulation tank installation by providing a commonly used coldness accumulating tank including a multi-layered accumulating part capable of being filled so that its freezing temperature may be lower as closer to the central side and higher as closer to the external peripheral side. SOLUTION: A commonly used coldness accumulation tank 54 partitioned in a concentric circular shape by means of plural side part heat insulating materials 47 to 49 made of urethane block, etc., and multiplied heat accumulation ports 50 to 53 are formed inside is provided. In each of storing parts 50 to 53 of the commonly used coldness accumulation tank 54, respective coldness accumulating agents 55 to 58 different in freezing temperature are stored so that the freezing temperature may becomes lower as closer to the central side and this temperature may become higher as closer to the outer peripheral side. As the result, the thickness of partitioning side part heat insulating materials 47 to 49 may be only a thickness corresponding to the temperature differences in the coldness accumulating agents 55 to 58 of mutually adjacent, and to the extent of reduction of used quantity owing to thinning of side part heat insulating materials 47 to 90, etc., for partitioning, the installation cost can be reduced.

摘要： PURPOSE:To utilize fluorocarbon for a cold heat using facility by efficiently recovering the cold heat with a low operating cost without entirely using the fluorocarbon and to suppress influence to be affected to an environment to a minimum limit. CONSTITUTION:An expansion unit 10 is rotatably driven by high-pressure hydrogen gas guided from a high-pressure hydrogen line 1 via a regenerative cooler 11 without mechanical power. The gas 2 is expanded by the unit 10 to be cooled, fed via one hydrogen absorbing alloy reactor 4, guided to a low-pressure hydrogen line 3, and hence absorbed from the line 1 by the reactor 4 while utilizing it to recover reaction heat. The gas 2 already absorbed by the other hydrogen absorbing alloy reactor 4 is used to cool a heat exchanging medium 18 by reaction absorption heat while discharging it to the line 3, and the medium 18 is circulated to a freezing warehouse 16 via a circulation channel 17.

摘要： PURPOSE:To enable power to be recovered from waste heat of low temperature by providing a vessel containing a solid to generate gas at pressure corresponding to heating temperature on solid-gas reaction and heating the gas up to the first temperature, a device for expanding gas generated from the vessel for recovering power, and another vessel for cooling gas discharged from the device. CONSTITUTION:A heating vessel 7 heats solid capable of solid-gas reaction due to heat from waste heat, and generates gas to be discharged through a gas outlet valve 9. A heat exchanger 6 heats gas in transport with waste heat. A power recovery device 1 is formed out of a one-stage turbine 2, a reheater 3, a two-stage turbine 4 and a generator 5. A cooling vessel 8 takes in exhaust gas from the turbine 4 through a gas inlet valve 10 and cools the gas. Solid-gas reaction generates gas at pressure corresponding to temperature. This gas is, therefore, heated with the heating vessel 7 to generate gas at the prescribed pressure. The gas is, then, passed through the device 1 and cooled with a cooling vessel 8 to generate gas at low pressure. As a result, gas at a constant pressure difference is applied to the device 1, thereby enabling power to be recovered.

摘要： PURPOSE:To enhance the separating capacity for a sample by directly abosrbing the heat of the buffer solution flowing through the position spaced apart from a wall surface by a heat conductive member to uniformize the temp. distribution in an electrophoretic tank. CONSTITUTION:In an electrophoretic apparatus, a required number of heat conductive members 12 composed of material quality having high heat conductivity such as fins or heat pipes are provided between the cooling walls 10, 10 of an electrophoretic tank 3 in a scattering state so as not to exert large effect on the flow of a buffer solution 6 to directly absorb the heat of the solution 6 so as to enable to discharge the same to the outside of the tank 3. The heat of the flowing-down solution 6 is absorbed by the members 12 to be discharged to the outside of the tank 3 from both end parts of the members 12. That is, it becomes possible that the heat of the solution 6 flowing down through the central part of the tank 3 incapable of being sufficiently cooled only by the cooling walls 10, 10 is absorbed and discharged out of the tank 3 and the temp. distribution of the solution in the tank 3 becomes uniform. Therefore, the generation of the natural convection of the solution can be suppressed and the separating capacity for a sample 9 can be enhanced.
