Abstract: A swivel hook comprises a hook body including a proximal part having an aperture formed at its upper end to define a pair of overhangs and a substantially J-shaped hook portion extending downward from the proximal part, an annular link having an connecting axle provided on one side thereof, the connecting axle having an enlarged head formed on its distal end, the enlarged head being inserted into the aperture into engagement with the overhangs; a locking member having a pair of opposing side walls defining therebetween a chamber; and biasing means mounted in the chamber. The proximal part of the hook body is pivotally mounted on the locking member within the chamber with the aperture closed by the opposing side walls and with the biasing means acting between the proximal part and the locking member for normally urging the locking member into engagement with the J-shaped hook portion.

Abstract: A structural member is produced using starting powder consisting of composite particulates each containing AlN grain within its surface covered by an Al layer of a single crystal structure, and Al alloy particulates of a single crystal structure, and then by sintering the Al layers of the composite particulates with the Al alloy particulates. The Al layers and the Al alloy particulates of the single crystal structure have no dislocation fault, crystal grain boundary. etc., produced therein, and for this reason, they have a low chemical activity. Therefore, the Al layers and the like have a characteristic that they are extremely difficult to oxidize. This ensures that the Al layers and the Al alloy particulates can be reliably sintered to achieve the densification of the resulting structural member.

Abstract: A lower mold attachment plate, on the upper surface of which the fixed mold half is attached, is fixed to a machine base. An upper mold attachment plate, to which the movable mold half is attached in opposite to the fixed mold half, is movable upwardly and downwardly by mold moving cylinders. A rotary disc, which has plural injection cylinder insertion holes in the same circle in vertical alignment with plural injection cylinder insertion holes of the upper mold attachment plate, is rotatably pivoted on the upper surface of the upper mold attachment plate. Plural injection units arranged over the rotary disc in predetermined distances along the circle are joined with the rotary disc as a unit. As the rotary disc is rotated to a divided angular position, a slide fastener chain is conveyed along the extension of the chain travelling path, by a predetermined length at every injection molding by means of chain conveyer.

Abstract: A cooling mold has first and second water cooling jackets provided inside the mold. A primary cooling water jetting mouth is located at a distance between 15 and 40 mm from the meniscus of the molten metal. A secondary cooling water jetting mouth is located at an interval of 20 to 45 mm between a contact point of a primary jet of cooling water and another contact point of a secondary jet of cooling water on an ingot. The primary and secondary cooling water jetting mouths are respectively set at an angle of 15 to 30 degrees and of 30 to 60 degrees relative to the ingot surface. The primary jet of cooling water from the primary mouth impinges on the molten metal cooled in the cooling mold at a distance from the meniscus to establish a transition boiling zone and a film boiling zone. The secondary jet of cooling water impinges on initial zones of the transition boiling zone and the film boiling zone to break-out a vapor film.

Abstract: A sintered high-toughness alumina-based composite body comprises a plate- or rod-like, corundum or alumina-based compound structure and another structure having a fine granular corundum structure and containing inevitable impurities. A sintered high-toughness alumina-based composite can be produced by mixing a crystal-growth-promoting additive with a first portion of alumina powder to prepare a mix A, mixing a crystal-growth-inhibiting additive with a second portion of alumina powder to prepare a mix B, granulating at least one of the mix A and the mix B into granules, mixing the mix A and the mix B into a mix C, forming tile mix C into a green body, and then firing the green body, whereby crystals of the corundum or alumina-based compound in the mix A are allowed to grow.
