A case is provided for holding an ultraviolet detecting device in a state wherein an electrode-side terminal portion of the ultraviolet detecting device is inserted into one end portion. A conducting portion is provided connected on one end to an electrode terminal portion of the ultraviolet detecting device with the other end led out from the other end portion of the case. A sealing member is provided attached removably to the case. The sealing member seals airtight between the inside and the outside of the case in a state wherein a cable of the conducting portion passes therethrough.

Socket for holding electronic device and flame sensor

A recessed portion is provided into which an ultraviolet detecting device is inserted, and a case is provided for holding removably in the state wherein the ultraviolet detecting device is inserted into the recessed portion. A conducting portion is provided that is connected on one end to the electrode portion of the ultraviolet detecting device and wherein the other end is led out from the case. The recessed portion is provided with first through fourth protrusions which insert into grooves that are formed in the ultraviolet detecting device.

A rolling-piston expander has a hermetic casing 7 provided with a suction pipe 3 and a discharge pipe 5, a cylinder 13 disposed in the casing, a roller 31 eccentrically rotated in the cylinder, an expansion chamber 39 defined by the roller and communicating with a suction port 47 and a discharge port 55, a shaft 19 for supporting the roller so that the roller may eccentrically rotate, a suction timing controller 51 consisting of the ports 47 and 51, for controlling the timing of the supply of gas into the expansion chamber, and a bypass for supplying high-pressure gas into the expansion chamber when the suction timing is off.

Rolling-piston expander apparatus

An air conditioning equipment is provided wherein reduction in size of an outdoor heat exchanger, improvement of reliability, and low cost can be achieved without reduction in system efficiency. In the air conditioning equipment, the same working medium is employed in Rankine cycle (first cycle) and refrigerant cycle (second cycle) and an expander and a compressor used in respective cycles are installed in the same enclosure.

Air conditioning equipment

A rolling piston type expansion machine eliminates the need for an open-close valve mechanism and smoothens the timing of inflow of high-pressure gas. The machine includes a cylinder having a discharge port and a roller freely gyratable or orbital in the cylinder. A freely movable blade supported in the cylinder has its tip in contact with the circumferential surface of the roller to form an expansion chamber. A gas passage is freely rotatably supported by a main bearing member and a secondary bearing member. The gas passage is formed in a main shaft having a crank shaft portion that gyrates or orbits the roller. An inlet port is provided along a shaft center of the main shaft. An inflow timing control portion controls inflow timing of the suction gas toward the expansion chamber via the inlet port of the gas passage.
