  • Publication number: 20230397387
    Abstract: A parts tower that stores reels storing components to be mounted on substrates includes storing sections storing the reels, loading and unloading sections in which the reels are disposed, a moving section that moves the reels inside the parts tower, an operation section receiving an instruction of unloading of the reels, and a controller. Some of the storing sections that are disposed around the loading and unloading sections are defined as unloading waiting sections. The controller performs a first moving process in which the reels that are to be unloaded relatively early among the stored reels to the unloading waiting sections are moved by the moving section before receiving the instruction of unloading the reels, and a second moving process in which the reels stored in the unloading waiting sections are moved to the loading and unloading sections by the moving section in response to receiving the instruction.

  • Patent number: 10495350
    Abstract: An ejector-type refrigeration cycle has a compressor, an ejector module, a discharge capacity control section, and a pressure difference determining section. The ejector module has a body providing a gas-liquid separating space. The pressure difference determining section determines whether a low pressure difference operating condition is met. The low pressure difference operating condition is an operating condition in which a pressure difference obtained by subtracting a low-pressure side refrigerant pressure from a high-pressure side refrigerant pressure a predetermined reference pressure difference or lower. The body is provided with an oil return passage that guides a part of a liquid-phase refrigerant to flow from the gas-liquid separating space to a suction side of the compressor. The discharge capacity control section sets a refrigerant discharge capacity to be a predetermined reference discharge capacity or higher when the low pressure difference operating condition is determined to be met.

  • Patent number: 10465957
    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.

  • Patent number: 10442274
    Abstract: An ejector refrigeration cycle device includes: a radiator that dissipates heat from a refrigerant discharged from a compressor; an ejector module that decompresses the refrigerant cooled by the radiator; and an evaporator that evaporates a liquid-phase refrigerant separated in a gas-liquid separation space of the ejector module. A grille shutter is disposed as an inflow-pressure increasing portion between the radiator and a cooling fan blowing the outside air toward the radiator. The grille shutter is operated to decrease the volume of the outside air to be blown toward the radiator when an outside air temperature is equal to or lower than a reference outside air temperature, thereby increasing the pressure of the inflow refrigerant to flow into a nozzle passage of the ejector module.

  • Patent number: 10378795
    Abstract: An ejector refrigeration cycle includes a bypass passage that guides a refrigerant on an outlet side of an evaporator drawn from a refrigerant suction port of an ejector to a suction port side of a compressor while bypassing a diffuser passage of the ejector. A differential pressure regulating valve is disposed as a bypass flow-rate adjustment device that adjusts a bypass flow rate of the refrigerant circulating though the bypass passage. An enlarged portion for gradually enlarging the passage area is formed at a most downstream part of the refrigerant flow in the bypass passage. During a low-load operation, the differential pressure regulating valve increases the bypass flow rate, thereby allowing the refrigerant to flow into the evaporator connected to the upstream side of a refrigerant suction port using the suction effect of the compressor.

  • Patent number: 10358947
    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.

  • Patent number: 10316865
    Abstract: An ejector has a nozzle, a body, a passage defining member and a drive portion. The body has a refrigerant suction port and a pressure increasing portion. A nozzle passage is defined between an inner surface of the nozzle and an outer surface of the passage defining member and has a minimum sectional area portion, a tapered portion, and an expansion portion. The minimum sectional area portion has a smallest passage sectional area. The tapered portion is located upstream of the minimum sectional area portion in a refrigerant flow direction and has a passage sectional area decreasing toward the minimum sectional area portion gradually. The expansion portion is located downstream of the minimum sectional area portion in the refrigerant flow direction and has a passage sectional area increasing gradually. The passage defining member has a groove that is recessed to increase the passage sectional area of the nozzle passage.
