Abstract: When an ejector having a variable nozzle and a variable throttle mechanism are integrated together as an ejector module, a nozzle-side central axis CL1 and a decompression-side driving mechanism have a twisted positional relationship, if the nozzle-side central axis CL1 is defined as a central axis of a nozzle-side driving mechanism in a displacement direction in which the nozzle-side driving mechanism of the ejector having the variable nozzle displaces a needle valve, and the decompression-side central axis CL2 is defined as a central axis of a decompression-side driving mechanism in a displacement direction in which the decompression-side driving mechanism of the variable throttle mechanism displaces a throttle valve. When viewed from the central axis direction of one of the nozzle-side central axis CL1 and the decompression-side central axis CL2, a driving portion corresponding to the one central axis is disposed to overlap with the other central axis.

Abstract: A compressor module for a heat pump cycle includes a compressor, a channel forming member configured to define therein a plurality of internal refrigerant channels through which refrigerant flows, and a cover member configured to define a housing space of a housing, which houses the compressor, together with the channel forming member. The housing is provided therein with a compressor-side inlet and a compressor-side outlet communicating to the internal refrigerant channels, and is provided with an outside connection port outside of the housing space and communicating to the internal refrigerant channels. The compressor has a refrigerant discharge port coupled to the compressor-side inlet, and a refrigerant suction port coupled to the compressor-side outlet. The outside connection port is connected to inflow and outflow sides of external component devices disposed outside the housing space, in component devices of the heat pump cycle.

Abstract: An ejector refrigeration cycle includes a compressor, a radiator, a branch portion, an ejector, a suction side decompressor, a windward evaporator, and a leeward evaporator. The ejector includes a nozzle portion and a pressure increasing portion. The windward evaporator and the leeward evaporator include at least one outflow side evaporation portion. The leeward evaporator includes a suction side evaporation portion. An outflow side evaporation temperature is a refrigerant evaporation temperature in the at least one outflow side evaporation portion of the leeward evaporator. A suction side evaporation temperature is a refrigerant evaporation temperature in the suction side evaporation portion of the leeward evaporator. At least one of the nozzle portion or the suction side decompressor is configured to adjust a refrigerant passage area such that a temperature difference between the outflow side evaporation temperature and the suction side evaporation temperature is at or below a predetermined reference temperature difference.

Abstract: An input device has an operative member on which switches are arranged to receive a pushing force. The input device has a control unit which is configured to store both a first correction coefficient and a second correction coefficient. The first correction coefficient may correct variations in displacement caused by differences in pushing positions on the operative member. The second correction coefficient may correct differences in sensitivity among a plurality of sensors. The control unit is configured to perform: correcting a plurality of displacements by the first correction coefficient and the second correction coefficient; and determining whether presence or absence of a push operation by comparing a summation of corrected values with a predetermined threshold value.

Abstract: A rotation operation device includes: a rotation operation section having a cylindrical shape; multiple recessed and projecting sections arranged on an axial end surface or a peripheral surface of the rotation operation section; a conductive section having a protruding section protruding toward each recessed and projecting section and an elastic section biasing the protruding section to each recessed and projecting section, and movable in a recess-and-projection direction when the rotation operation section rotates; an electrode section changing a capacitance in accordance with a movement of the conductive section; and a detecting section detecting the change in the capacitance. The conductive section is moved in turn in the recess-and-projection direction at a different timing. The detecting section detects a rotation direction and a rotation quantity of the rotation operation section by means of a combination pattern of the change in the capacitance.
