Abstract: A wafer etching and impurity analysis method is presented in which a wafer is held in a vessel having gas introduction and exhaust ports, a solution including a mixture of hydrofluoric acid and nitric acid alone or together with sulfuric acid is bubbled with a carrier gas without being heated, which generates a gas containing vaporized hydrofluoric acid and nitric acid, and the inside of the vessel is purged so that the amount of gas supplied is kept constant at all times. All or a specific portion of the wafer is cooled to a specific temperature. Consequently, the gas is condensed on the surface of the wafer, which allows the required portion of the wafer to be etched. The method reduces the amount of liquid needed for residue recovery, the amount of admixed silicon during impurity analysis, and the concentration time.

In the recycling method, scrap of high-tensile steel plate and scrap of ordinary steel plate are collected together in a batch collecting process and, then, in a preparing process, the scrap steel plates collected are melted and if not less than 0.7 weight % manganese is contained in the hot metal, then the hot metal is prepared so that a sulfur content in the range of 0.02 to 0.2 weight % in the hot metal and rare earth element or misch metal which is two times as much as the sulfur content is added to the hot metal. To obtain spheroidal graphite cast iron, spheroidizing agent (which preferably comprises no rare-earth element but comprises bismuth) is added further to the hot metal after that.

Abstract: In a sliding contact guide for a chain, a guide body is composed of a shoe having a front surface on which the chain slides, and a plate-receiving portion provided on the back of the shoe. The shoe and plate-receiving portion are integrally molded from a synthetic resin. A reinforcing plate is inserted and fitted into a longitudinal slot in the plate-receiving and the sliding contact guide is attached to a frame by a pivot pin which extends through aligned mounting holes in the guide body and the reinforcing plate. Locking pieces formed in the plate-receiving portion, have tapered surfaces on their tips that engage locking holes in the plate and exert a biasing force on edges of the locking holes which urges the plate against the back of the shoe. The reinforcing plate and the guide body are reliably secured together and, even when the guide is vibrated, movement of the reinforcing plate in the slot of the guide body is prevented, so that low noise and long life are attained.

Abstract: A wafer etching and impurity analysis method is presented where a wafer is held in a vessel having gas introduction and exhaust ports, a solution including a mixture of hydrofluoric acid and nitric acid alone or together with sulfuric acid is bubbled with a carrier gas without being heated, which generates a gas containing vaporized hydrofluoric acid and nitric acid, and the inside of the vessel is purged so that the amount of gas supplied is kept constant at all times. The molar ratio of the hydrofluoric acid and nitric acid (and sulfuric acid if used) in the solution is set to a specific value. The amount of gas introduced is specified. All or a specific portion of the wafer is cooled to a specific temperature between 0 and 20° C. Consequently, the gas is condensed on the surface of the wafer, which allows the required portion of the wafer to be etched and the amount of required in-plane etching to be uniform.

Abstract: In a transmission comprising an endless silent chain and a sprocket the inside tooth faces of the link plates of the chain are identical to tooth profiles, arranged axially, of a hob cutter for forming teeth of the sprocket. The inside and outside tooth faces also satisfy Hi=Ho+Hs, where Hi is the distance from a pin center line Lp to a pitch line Li of the inside tooth faces, Ho is a distance from the pin center line to a pitch line Lo of the outside tooth faces, and Hs is the amplitude of polygonal motion of the chain. Each link plate also has a concave bottom surface between its teeth to avoid interference with edges of the involute teeth arising due to the chain polygonal motion amplitude when the outside tooth faces are brought into meshing engagement with the involute teeth and become seated thereon.

Abstract: A silent chain is provided with strength and elongation of respective link rows made uniform, elongation of every link made equal regardless of elastic and/or plastic deformation, and inexpensive production cost. The silent chain includes a first link row, a second link row, a connection pin and a pin stopper. Each of the first and second link rows consists of a guide plate and the same number of link plates whose shapes and sizes are the same. The first and second link rows are staggered in the longitudinal direction of the chain, and connected in alternating, interleaved relationship by connection pins. The guide plates and the link plates of the first and second link row are relatively rotatable to the connection pins. The first and second link rows are alternately arranged in mirror image symmetry.

Abstract: A random arrangement type silent chain is provided, which restricts run-upon and reduces contact noise and vibration noise of the free span of the chain, and also restricts abnormal elongation and excessive load during power transmission. In the silent chain a first link plate, which begins to engage with a sprocket tooth by its inner crotch and sits on the sprocket teeth by its outer flanks, and a second link plate, which engages with and sits on the sprocket teeth only by engagement with its outer flanks, are mixed and combined in an endless chain in the longitudinal direction. The mixture ratio of the first link plates to the total link plates is less than 50%, at least one or more of the second link plates are arranged before and after each of the first link plates, and the number of second link plates arranged before and after each first link plate varies randomly along the length of the chain.

Abstract: A sliding contact guide for a transmission chain or belt comprises a synthetic resin shoe having an integrally molded, slotted plate-receiver for receiving a metal reinforcing plate, or alternatively a reinforcing base to which a shoe is attached by clips molded as parts of the shoe. In the guide having the metal reinforcing plate, gaps between the plate and the slot are filled with a buffer material. In the guide comprising a shoe clipped to a reinforcing base, a gap between the shoe and the base is filled with a buffer material. The buffer material prevents relative wobbling between the guide components, and increases manufacturing tolerances, thereby suppressing impact noise and also reducing production cost.

Abstract: A silent chain includes guide link rows and joint link rows arranged alternately and articulately connected in an endless fashion by rocker joint pins each composed of a longer pin and a shorter pin. In each guide link row, the longer pin is fitted with two guide plates and also inserted through link plates disposed between the guide plates. In each joint link row, the shorter pin is inserted through link plates. The longer pin and the shorter pin are initially formed in a straight configuration and have the same cross-sectional shape. When the silent chain is stretched substantially straight after having been subjected to a proof load, the pitch of the guide plates is made slightly greater than the pitch of adjacent contact points between the longer pins and the shorter pins of the rocker joint pins in the guide link rows so that the longer pins are elastically deformed into a bow-like configuration bent toward the mating shorter pins.
