Abstract: A chain guide is composed of a resin shoe engageable with an aluminum base frame. The shoe has a hook formed at a chain entry end for engagement with a chain entry end of the base frame, and a C-shaped hook at the chain exit end engageable with a side edge of the base frame. The shoe is engaged with the base by first engaging the C-shaped hook with the side edge of the base frame, then flexing the chain entry end of the shoe until the hook at the chain entry end can receive the chain entry end of the base. The shoe is moved a short distance toward the chain exit end of the base until a projection formed on a back surface of the shoe near the chain entry end snaps into a depression formed on a front surface of the base frame, locking the shoe and base together.

Abstract: A butterfly valve including a housing having a hollow passage defining a flow path and a shaft mounted to the housing and extending transversely across the flow path. The shaft defines an axis of rotation for a butterfly valve element carried on the shaft. The valve element can be rotated about the axis between an open position permitting flow along the flow path and a closed position restricting flow along the flow path. The butterfly valve element includes a thin, substantially disc-shaped, flow-regulating plate having front and rear faces and a flow-straightening vane extending from one of the faces transversely relative to the shaft. The vane is solid and extends substantially to the wall of the hollow passage thereby defining separate non-communicating flow channels on opposite sides thereof for reducing flow turbulence and for straightening and accelerating flow across the plate.

Abstract: The plates of transmission chain for an engine are formed with a guide-contacting configuration composed of spaced flat surfaces that come into sliding contact with a flat chain guide, and convex surfaces, continuous with and between the flat surfaces, for sliding contact with a convex chain guide. The convex surfaces are connected by a concave surface that, with the guide surface, forms an oil-retaining clearance. The radius of curvature of the convex curved surfaces of the plate preferably increases gradually from the location where they meet the flat surfaces toward the location where they meet the concave surface. The plates can have the same configuration on the side facing the inside of chain loop as on the side facing the outside of the chain loop.

Abstract: A Ni—Pt alloy and target superior in workability containing 0.1 to 20 wt % Pt and having a Vickers hardness of 40 to 90. A method of manufacturing the Ni—Pt alloy comprises steps of subjecting a raw material Ni having a purity of 3N level to electrochemical dissolution, neutralizing the electrolytically leached solution with ammonia, removing impurities through filtration with activated carbon, blowing carbon dioxide into the resultant solution to form nickel carbonate, exposing the resultant product to a reducing atmosphere to prepare high purity Ni powder, leaching a raw material Pt having a purity of 3N level with acid, subjecting the leached solution to electrolysis to prepare high purity electrodeposited Pt, and dissolving the resultant high purity Ni powder and high purity electrodeposited Pt. The method enables rolling of the Ni—Pt alloy ingot upon reducing the hardness thereof, which results in the stable and efficient manufacture of a rolled target.

Abstract: In a silent chain having interleaved guide rows and joint rows, guide plates at the outer sides of the guide rows are connected by engagement pins which extend through overlapping recesses formed on the outer flanks of the guide row plates, and on the inner flanks of the joint row plates. The engagement pins contact sprocket teeth before the outer flanks of the guide row plates contact the sprocket teeth. Cutouts formed in the guide plates adjacent the engagement pins allow the guide plates to deform and thereby absorb the impact imparted to the engagement pins by the sprocket teeth.
