PURPOSE:To suppress the increase in the cost of equipment by a method wherein a cassette placing pedestal is provided in a preparatory chamber in a pivotally and vertically moving manner, thereby enabling to arbitrarily change the supply and discharge direction of a wafer. CONSTITUTION:An electrode 11 for placement of a wafer whereon an RF power source 13 is provided in a pivotally moving manner i...

A non-contact laser engraving apparatus for reproducing on a workpiece an image, the image being formed on or in proximate relationship to a specularly reflecting surface of a cyclindrical mirror being scanned laterally by a laser beam with the mirror in a focal plane. The image is formed of a diffusely reflective substance with the beam then being appropriately brought to a focus at the workpiece...

PURPOSE:To enable to improve the yield rate of the titled device by a method wherein a sensor which is used to detect a left over wafer is provided on the upper aperture of a cassette, thereby enabling to prevent the wafer damage generating by a left over wafer. CONSTITUTION:A pair of light projecting type sensor 6a, facing the upper aperture of a cassette 2b, and a light-receiving type sensor 6b ...

In the bending and tempering of glass sheets supported on a ringlike member for conveyance of the bent glass sheet through a cooling station, a transfer device for unloading the bent, tempered glass sheet is provided. The transfer device is so constructed and arranged that it does not cause a bottleneck in high speed, ? production of bent, tempered glass sheets, avoids uncontrolled departures from...

A shock absorbing pad is formed of first and second interleaved constituent components of different hardness which are interleaved through the thickness of the pad for absorbing forces applied in the direction of the pad thickness. The pads are formed by die cutting interim pads from mats of the first and second materials with the pads comprising constituent components that are separable. The cons...

An electromechanical measuring converter pin, particularly for measuring forces having varying influence lines, the pin has a pair of two opposite cylindrical and flat surfaces (2,3). The points or lines of application of the force and reaction force (4,5) are on the cylindrical surfaces (3). Recesses (7,8) are machined along the full length of both flat surfaces parallel with and extending over t...

A heavy duty disc brake is disclosed which is provided with an automatic adjuster mechanism to limit retraction of the friction elements to a substantially predetermined amount to thereby maintain the running clearances between the friction elements and the brake rotor substantially constant. The adjustment mechanism includes an extensible member which is slidably mounted within the caliper housin...

An anode for generating available chlorine from seawater by electrolysis which comprises a substrate made of titanium or an alloy thereof, and a coating on said substrate which is made up of an active anode material layer containing 15-85 wt % of platinum, 5-35 wt % of iridium dioxide, and 10-15 wt % of ruthenium dioxide. The anode has greatly improved anode performance such as current efficiency,...

Disclosed is a bifunctional filter for the treatment of an exhaust gas comprising a plurality of inlet chambers wherein the exhaust gas is introduced, a plurality of outlet chambers from which the exhaust gas is released, and a wall separating each of the inlet and outlet chambers, wherein the wall comprises a ceramic material permeable to gas but impermeable to particles and wherein the wall furt...

D-4780 C-3256 ENHANCED OXIDE WHISKER GROWTH ON COLD-ROLLED ALUMINUM-CONTAINING STAINLESS STEEL FOIL Alumina whiskers are grown on cold-rolled Fe-Cr-Al alloy foil by a two-step oxidation treatment. A bare metal surface is initially oxidized by heating while exposing to a predominantly inert atmosphere containing 0.1 volume percent oxygen or less. Thereafter, the surface is further oxidized by heati...

Disclosed is a compensating cable adapted to be used in combination with an elevator cab, counterweight, hoist rope and traveling cable. The compensating cable is composed of a sheath, at least one elongated strength member such as a link chain or stranded wire rope, made from metal or other materials of high tensile strength disposed in the sheath and the volume of the sheath not otherwise occupi...

A lid for the luggage compartment of a motor vehicle has a hinge pin with opposed ends supported in upwardly opening sockets mounted on vehicle body. Spring biased latches are carried by the sockets and have lugs projecting over the hinge pin to latch the hinge pin and enable pivotal movement of the lid about a hinge axis defined by the hinge pin. The latches are withdrawn to unlatching positions ...
