  • Air-conditioning apparatus
    Patent number: 9115931
    Abstract: In an air-conditioning apparatus, a heat source side heat exchanger, intermediate heat exchangers, and use side heat exchangers are separately formed and adapted to be disposed at separate locations, respectively. There is provided a defrosting operation function to melt frost attached around the heat source side heat exchanger, and a heating function during defrosting operation that drives a pump to circulate a heat medium and supply heating energy to the use side heat exchangers in need of heating to perform heating operation. The defrosting operation function can be executed by switching a four-way valve to cooling side to introduce a high-temperature high-pressure refrigerant flowed out of the compressor into the heat source side heat exchanger.

  • Refrigeration cycle apparatus
    Patent number: 8904812
    Abstract: A refrigeration cycle apparatus includes a refrigerant circuit of a refrigeration cycle through which a refrigerant that transits in a supercritical state is allowed to flow, and a flow dividing device that divides the flow of a high-pressure liquid refrigerant in a subcritical state into two or more parts. The flow dividing device is configured such that the device is oriented substantially in the horizontal direction or substantially upward in the vertical direction relative to the direction of flow of the refrigerant in a liquid state. With such a configuration, the flow of refrigerating machine oil is equally divided, thus offering high energy saving while keeping heat-medium conveyance power at a low level without reducing the heat exchanging performance.

  • LASER PROCESSING APPARATUS, METHOD OF LASER PROCESSING, METHOD OF FABRICATING SUBSTRATE, AND METHOD OF FABRICATING INKJET HEAD
    Publication number: 20140312015
    Abstract: In the case where the workpiece (1) is processed, the laser beam is S-polarized by an optical modulator (7). Thus, the laser beam is mainly diverted toward a workpiece (1) by a polarizer (6). An optical path through which the laser beam passes is caused to have a high light converging ability with respect to a target spot by an optical device (9). In the case where the workpiece (1) is not processed, the laser beam is P-polarized by the optical modulator (7). Thus, the laser beam is mainly diverted to a beam damper (10) side by the polarizer (6). However, the workpiece 1 is irradiated with the laser beam having leaked from the polarizer (6). An optical path through which the laser beam passes is caused to have a low light converging ability with respect to the target spot by the optical device (9).
