Abstract: An ejector includes a body having a nozzle passage that depressurizes a refrigerant flowing out of a swirling space in which the refrigerant is swirled, a suction passage that draws a refrigerant from an external, and a diffuser passage that mixes an ejection refrigerant jetted from the nozzle passage and a suction refrigerant drawn from the suction passage together and pressurizes the mixed refrigerant. The body also has a gas-liquid separation space that separates the refrigerant flowing out of the diffuser passage into gas and liquid by an action of a centrifugal force, and multiple liquid-phase refrigerant outflow passages through which the liquid-phase refrigerant separated by the gas-liquid separation space flows out to the multiple evaporators.

Abstract: A body of an ejector includes a diffuser passage, in which an ejection refrigerant jetted from a nozzle passage and a suction refrigerant drawn from a suction passage are mixed together and pressurized by arranging a passage formation member, and a gas-liquid separation space, in which the refrigerant flowing out of the diffuser passage is separated into gas and liquid by the action of a centrifugal force. An inlet part of an oil return passage that is open in the gas-liquid separation space is arranged at a position closer to an outer peripheral side than to an axis center of the passage formation member.

Abstract: This combined cycle gas turbine plant has a gas turbine (104) and a steam turbine (106) mounted on the same shaft. A control system is configured for switching the plant from a rated mode of operation, in which the plant is operated on gas turbine output and steam turbine output, to a reduced load mode of operation, in which the plant is operated on gas turbine output alone. The switch from the rated mode of operation to the reduced load mode of operation occurs if plant demand decreases below a predetermined threshold. The steam turbine is run under full speed no load conditions in the reduced load mode of operation, and is heated using controlled steam admission, to maintain the steam turbine in a heated ‘stand-by’ state.

The swirling promotion part includes a flow regulation plate that promotes a swirling flow of the refrigerant flowing in the diffuser passage.

Abstract: An ejector-type refrigeration cycle includes an upstream side gas-liquid separator that separates a refrigerant that has flowed out of a diffuser portion of an ejector into gas and liquid and allows the separated liquid-phase refrigerant to flow to an evaporator without storing the separated liquid-phase refrigerant, and a downstream side gas-liquid separator that separates the refrigerant flowing out of the upstream side gas-liquid separator into gas and liquid, stores the separated liquid-phase refrigerant, and allows the separated gas-phase refrigerant to flow out toward an inlet side of a compressor. The ejector-type refrigeration cycle includes a refrigerant oil bypass passage for introducing a refrigerator oil within the diffuser portion into the downstream side gas-liquid separator.

Abstract: An ejector includes a body member having a depressurizing space that depressurizes a refrigerant which flows out of a swirling space that swirls the refrigerant, a suction passage that draws the refrigerant from an external, and a pressurizing space that mixes a refrigerant jetted from the depressurizing space with a refrigerant drawn from the suction passage and pressurizes the mixed refrigerant, and a conical passage formation member arranged in the depressurizing space and in the pressurizing space. A nozzle passage is formed of a refrigerant passage between an inner peripheral surface of the depressurizing space and an outer peripheral surface of the passage formation member, and a diffuser passage is formed of a refrigerant passage between an inner peripheral surface of a portion that defines the pressurizing space and an outer peripheral surface of the passage formation member.

Abstract: An ejector-type refrigeration cycle includes a radiator radiating heat of refrigerant discharged from a compressor, an ejector depressurizing the refrigerant cooled in the radiator, a gas-liquid separator separating gas and liquid of the refrigerant flowing out of a diffuser portion of the ejector, an evaporator disposed in a refrigerant passage connecting the gas-liquid separator and a refrigerant suction port of the ejector, and an opening-closing valve switching between a first refrigerant flow path, in which an ejection refrigerant ejected from a nozzle portion of the ejector flows out of the diffuser portion, and a second refrigerant flow path, in which the ejection refrigerant flows out of the refrigerant suction port. When a rotation rate of the compressor is lower than or equal to a standard rotation rate, the first refrigerant flow path is switched to the second refrigerant flow path.

Abstract: An ejector refrigeration cycle includes an upstream-side branch portion for branching a flow of a refrigerant flowing out a radiator, an upstream-side ejector having an upstream-side nozzle for decompressing one of the refrigerants branched by the upstream-side branch portion, and a gas-liquid separator for separating the refrigerant flowing out the upstream-side ejector into gas and liquid phase refrigerants. The liquid-phase refrigerant flowing out of the gas-liquid separator is decompressed by a low-pressure side fixed throttle and allowed to evaporate at a first evaporator. The other refrigerant branched by the upstream-side branch portion is decompressed by a high-pressure side fixed throttle and allowed to evaporate at a second evaporator. A merging portion merges the refrigerant flowing out of the first evaporator with the refrigerant flowing out of the second evaporator, so that the merged refrigerant is sucked from an upstream-side refrigerant suction port of the upstream-side ejector.

Abstract: In an ejector, a passage formation member is disposed inside a body forming a space therein. Provided between an inner peripheral surface of the body and the passage formation member are a nozzle passage functioning as a nozzle, a mixing passage in which an ejection refrigerant ejected from the nozzle passage and a suction refrigerant drawn through a suction passage are mixed together, and a diffuser passage that converts a kinetic energy of the refrigerant that has flowed out of the mixing passage into a pressure energy. The mixing passage has a shape gradually reducing in cross-sectional area toward a downstream side in the refrigerant flow.

Abstract: There is a problem in that when the demand accuracy with respect to a semiconductor pattern dimension comes close to a resist molecule size with miniaturization, the device performance is deteriorated due to edge roughness of a resist pattern to exert a bad influence on the system performance. The present invention overcomes the problem by the procedure in which super-molecules which are small in dimension as compared with the conventional polymers are used as main components, the reaction number required for the change of molecule solubility is made constant and as large as possible, and an acid generator is made clathrate or combinatory n super molecules to make an acid catalyst concentration large. As a result, it is possible to form a pattern of molecular accuracy with high productivity even with respect to the pattern dimension less than 50 nm, thereby realizing the high performance system.
