Abstract: A receiver-tank for use in a refrigeration cycle of this invention is provided with a filtering layer 435 formed so that an upper space 402 is formed above the filtering layer 435 in a tank main body 401. An upper end of a refrigerant outlet 441 in a tank bottom wall 421 is opened toward the upper space 402. The refrigerant flowed into the tank main body 401 from the refrigerant inlet 431 passes through the filtering layer 435 upwardly, and forms liquid-stagnation R in the upper space 402. The liquefied refrigerant of liquid-stagnation R flows out of the refrigerant outlet 441. Thereby, only the stable liquefied refrigerant can be extracted more assuredly.

The refrigerant-discharging-passage penetrates the desiccant-filled-portion and has an inlet formed so as to open toward the upper space at an upper end of the desiccant-filled-portion and an outlet formed at a bottom portion of the tank main body.

Abstract: A layered heat exchanger for use as a motor vehicle air conditioner evaporator comprises pairs of generally rectangular adjacent plates, which are joined together in layers with the corresponding recesses of the plates in each pair opposed to each other to thereby form juxtaposed flat tubes each having a U-shaped fluid channel, and front and rear headers in communication respectively with opposite ends of each flat tube. The turn portion of U-shaped fluid channel of the flat tube has a fluid mixing portion comprising many small projections, and a rectifying portion comprising parallel long projections along a flow of fluid. The channel turn portion rectifies the flow of fluid and mixes the fluid at the same time, permitting the fluid to flow through the turn portion smoothly to result in a diminished fluid pressure loss, an improved heat transfer coefficient and improved performance.

The separating wall has a plurality of apertures formed in a scattered state for communicating the inlet side upper space and the outlet side upper space each other. The accumulator includes an oil returning tube having a lower inlet opening and an upper outlet opening. The oil returning tube is disposed in the tank such that the lower inlet opening and the upper outlet opening are located at a bottom portion of the tank and at the refrigerant outlet port, respectively.

Abstract: A tank of an accumulator is divided into an upper room and lower room by a dryer unit.

The right and left upper divided rooms communicate with each other through a plurality of apertures that are provided in the separating wall. Further, an oil returning tube is integrally formed with the dryer unit, and a filter is provided in the dryer unit.

Abstract: In a telescope, the adjustment order is limited so that dioptric power adjustment is made after adjustment of a distance between a pair of optical systems is completed. A pupil distance and a dioptric power correction amount are stored in a memory for every user. When a user uses the telescope, his or her pupil distance and dioptric power correction amount are read out from the memory to automatically make adjustment.

Abstract: A mounting device on a camera has a mounting member to fit with an accessory so as to mount the accessory on the camera by sliding it. The mounting member which is molded out of plastic in one piece has eaves-like portions overhanging from an upper portion thereof in opposite directions intersecting perpendicularly to a mounting direction of the accessory, thus having a generally T-shaped cross section. The mounting member has a groove running in the mounting direction at a top central portion for receiving a projecting portion of the accessory so as to determine a horizontal (lateral) position of the accessory relative to the camera. The eaves-like portions receive mating members of the accessory thereunder so as to determine a vertical position of the accessory relative to the camera.
