A single vapour system for soldering, fusing or brazing includes vertically disposed chambers which provide a draining and drying zone (16) above a vapour processing zone (18). Draining occurs in the upper zone with no additional heat being added in vapour recovery. A sealing system (42, 44) is utilised which is actuated by the carrier elevator (30) as an article-carrying basket (32) is moved into...

PURPOSE:To fix a completely cut off wafer to a jig without fail for making cleaning and drying operations acceptable by a method wherein vacuum attracting holes are provided on the positions roughly symmetrical to the center of each pellet. CONSTITUTION:A jig 1 supporting a tape 7 whereto a wafer 6 (pellet group in a mode of a wafer) completely cut off by dicing is adhered is composed of a disc 2 ...

A non-woven material and a method for making it, for use as a backing for a semipermeable membrane which comprises binding fibres, the distribution of which corresponds to that of a wet-laid non-woven material, the binding fibres being fused and flattened, without restriction of the porosity of the material in the surface region of the material.

A nonwoven fabric having a smooth surface, especially for use as support material for semipermeable membranes, comprising a support mat into which at least one surface thereof, an open-structured, continuous covering layer of fine, thermoplastic particles is calendered.

PURPOSE:To reduce the manufacturing cost of an impact absorptive steering shaft by using a system in which binder is provided in the coupling part between an upper shaft and a lower shaft, having a non-circular cross section to be connected mutually, and energy is absorbed by the frictional resistance of the couplling part and the shearing strength of the binder. CONSTITUTION:A steering shaft 10 i...
