摘要： 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.
摘要翻译：用作机动车辆空调蒸发器的层状热交换器包括一对大致矩形的相邻板，它们彼此连接在一起，每对相应的板的相应凹槽彼此相连，从而形成并置的扁平管，每个扁平管具有 U形流体通道，以及分别与每个扁平管的相对端连通的前后集管。扁平管的U形流体通道的转弯部分具有包括许多小突起的流体混合部分，以及包括沿流体流动的平行的长突出物的整流部分。通道转弯部分对流体进行整流并同时混合流体，使流体平稳地流过转弯部分，从而导致流体压力损失减小，传热系数提高，性能提高。

摘要： An accumulator includes a tank, a refrigerant inlet port provided at an upper portion of the tank, a refrigerant outlet port provided at the upper portion of the tank, a dryer unit disposed in the tank at an intermediate portion along a direction of height of the tank, and a separating wall extending upwardly from the dryer unit and dividing an upper inner space of the tank above the dryer unit into an inlet side upper space located at the refrigerant inlet part side and an outlet side upper space located at the refrigerant outlet side port. 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.
摘要翻译：蓄能器包括一个储罐，一个设在罐的上部的制冷剂入口，一个设在罐上部的制冷剂出口，一个干燥单元，设置在罐的沿着高度方向的中间部分罐和分隔壁，其从干燥器单元向上延伸并将干燥器单元上方的罐的上部内部空间分成位于制冷剂入口部侧的入口侧上部空间和位于制冷剂出口侧的出口侧上部空间港口。分隔壁具有以分散状态形成的多个孔，用于使入口侧上部空间和出口侧上部空间相互连通。蓄能器包括具有下入口和上出口的回油管。回油管设置在罐中，使得下入口和上出口开口分别位于罐的底部和制冷剂出口处。

摘要： In a camera automatic diaphragm control device of the type wherein scene light is measured through the diaphragm aperture during the stopping-down operation thereof, which is arrested when the measured light value reaches a given level with respect to manually set exposure parameters, thereby determining the diaphragm aperture, structure is provided for positively ensuring that the diaphragm aperture is left fully open when the set exposure parameters and the measured light require such diaphragm aperture setting. The diaphragm aperture control device is employed in a single lens reflex camera with a reflex mirror retractable from a viewing position at selected times in dependence on whether the diaphragm aperture remains fully open or is reduced.

摘要： A mounting structure for levers and the like such as in a reflex camera mirror box includes a metal base plate which may be the wall of the box and one or more tongues stamped from and bent outwardly perpendicular to the base plate and a synthetic organic polymeric resin having low friction and low light reflectivity properties molded to integrally form a layer on the base plate inside face, portions to fill the openings in the plate left by the tongues and externally cylindrical sheaths at least partially enveloping the tongues and functioning as reinforcing cores and defining projections which serve as pivots for swingably supporting levers, as lever stop abutments or for other functions. Where a projection is exposed to little stress, the core tongue may be omitted and by providing recesses in a tongue circumferential surface, the connection of the sheath to the plate covering resin layer may be omitted.
