Abstract: A brazing flux comprises cesium fluoride, aluminum fluoride, and crystalline aluminum hydroxide or aluminum oxide or both which form a crystalline compound having the following composition and containing cesium in the form of a complex salt:x.multidot.CsF-y.multidot.AlF.sub.3 -1/2.multidot.z.multidot.[Al.sub.2 O.sub.3 .multidot.nH.sub.2 O and/or Al.sub.2 O.sub.3 ]where x+y+z=100, x/y.ltoreq.3, 42.ltoreq.x.ltoreq.66, and z.gtoreq.2in terms of mol %. The crystalline compound has a melting point of 440.degree. to 580.degree. C.The brazing flux is non-corrosive and safe to use, and well suited for a brazing aluminum materials with a high magnesium content and also for torch brazing.

Abstract: A liquid crystal display device has a birefringence control type liquid crystal display unit including a pair of substrates having electrodes on their first major surfaces and arranged with a predetermined distance therebetween such that the electrodes face each other, a liquid crystal material having a negative dielectric anisotropy, the material being disposed between the substrates, liquid-crystal molecules of the liquid crystal material being aligned vertically such that longitudinal axes of said molecules are inclined at a slight pretilt angle in respect of an axis vertical to the substrates when no voltage is applied to the electrodes, a pair of polarizing plates arranged on second major surfaces of the substrates, and a device circuit for driving the liquid crystal device in a multiplex manner. This device is characterized in that the liquid crystal material has a helical pitch in the state wherein the material is not disposed between the substrates, and the relationships of d.ltoreq.p and 50.ltoreq.f.

Abstract: A heat-pipe device for transferring heat generated by a heat-generating element, having at least one heat-pipe body which is an extrudate of plate-like configuration made of aluminum or its alloy, the heat-pipe body including a planer-structure portion which has on one side thereof a flat face to which the heat-generating element is directly fixed, the heat-pipe body further including a plurality of passage-defining portions which protrude from the other side of the planer-structure portion and extend parallel to, and apart a predetermined distance from, each other, each passage-defining portion having therein a flow passage which is fluid-tightly charged with a working fluid for transferring the heat generated by the heat-generating element. Also is disclosed a heat-sink device for cooling a heat-generating element, having at least one heat-pipe body including a planer-structure portion and a plurality of passage-defining portions.

Abstract: In a liquid crystal device, liquid crystal molecules are twisted at a predetermined angle .theta. within the range of 180.degree. to 360.degree. between a pair of substances. Molecular alignment films are formed on the inner surfaces of the pair of substrates such that an angle .alpha. between the axes of the adjacent liquid crystal molecules falls within the range of 0.degree. to 40.degree.. A liquid crystal composition having a twist abilities falling within the range of .theta.-(2500/.theta.)+.sqroot..alpha. (degrees) to .theta.-(12500/.theta.)+.sqroot..alpha. (degrees) is filled between the substrates, thereby eliminating a memory phenomenon and alignment defects such as reverse twisting alignment defects and at the same time improving multiplexing drive characteristics.

Abstract: An evaporator for refrigerators and the like, comprising a sheet and at least one refrigerant flow passage assembly which includes a multi-passage unit having a plurality of parallel flow passages, an inlet header pipe connected to the inlet openings of the flow passages and an outlet header pipe connected to the outlet openings of the flow passages. The sheet which carries on one surface thereof the passage assembly or assemblies is bent to form a rectangular box-like structure of a cooler for a freezing chamber formed in the refrigerators.
