摘要： A subcooler is made up of a plate type heat exchanger. The accumulator is located between a compressor and the subcooler in a width direction of an outdoor unit in a planar view. The subcooler overlaps with the accumulator in the width direction in the planar view. As a result, a compact heat pump can be provided when the subcooler is a plate type heat exchanger.

摘要： A thermoelectric generating unit is configured to generate based on a temperature difference between a cold side and a hot side. A heating part includes a plate-like hollow member and tubular member. The hollow member is provided along a hot-side surface of a thermoelectric transducer, and forms a plate-like cavity inside. The tubular member forms a tubular cavity which communicates the plate-like cavity, with two open ends of the tubular member being positioned distantly from each other and connected to the plate-like hollow member. The tubular member is heated from outside by a hot fluid. The plate-like cavity and the tubular cavity form a circulation path in which a heating medium charged in the cavities circulates.

摘要： A work screen display system including a position information obtaining unit for obtaining position information on a work vehicle based on positioning correction information supplied from a first reference station; a region shape determination unit for determining a shape of a specific region where the work vehicle performs autonomous travel, based on positioning correction information supplied from a second reference station; and a display control unit for displaying, on a display unit, a specific region indication section indicating the specific region determined by the region shape determination unit. The display control unit displays the specific region indication section in a display mode that varies between a case where the first and second reference stations are identical and a case where the first and second reference stations are not identical

摘要： An internal combustion engine in which when the gas temperature of a fuel reformation chamber when a piston in a fuel reformation cylinder reaches the compression top dead point is estimated to be equal to or higher than a soot generation lower limit temperature set according to an equivalence ratio of the fuel reformation chamber, a reaction gas temperature adjusting operation for suppressing or reducing an increase in the reaction gas temperature in the fuel reformation chamber is executed. Further, a closing timing of an air-intake valve is changed to reduce an effective compression ratio of the fuel reformation chamber.
