    摘要: A torsional damper mounted to a crank shaft of an internal combustion engine has a hub provided with a rim portion and a fixing portion, and a boss welded to the rim portion. A mass body is arranged in an outer side of the rim portion via a cylindrical elastic body. A seal element of an oil seal mounted to an engine assembly makes contact with an outer circumferential surface of the boss. The hub 11 has a carbon equivalent of 0.5% or less, and a boss has a carbon equivalent of 0.5% or less and a carbon content of 0.2% or more. Induction hardening is applied to a portion of the boss with which the oil element makes contact.

    摘要: Insertion guides are mounted to slide blocks supported by a guide to be close to or away from each other. The slide blocks are meshed with nut parts of a ball screw threaded in both directions. When the ball screw is rotated via a driving pulley, a belt, and a driven pulley by a rotating/driving device set in an insertion head, the slide blocks and insertion guides mounted to the slide blocks are moved, so that an insertion pitch is changed. When the insertion head is rotated by a rotating/driving device via a driving pulley, a belt, and a driven pulley, an insertion direction is changed as well.

    摘要: There is disclosed a process for preserving solder paste which comprises housing solder paste in a vessel which is substantially free from oxygen and moisture and is imparted with gas barrier properties. The process is preferably carried out by housing the solder paste together with an oxygen absorbent not requiring moisture for absorbing oxygen (e.g. unsaturated fatty acid compound and chain hydrocarbon polymer having unsaturated groups) and optionally a dehumidifying agent and/or an acidic gas absorbent in the above vessel and subsequently hermetically sealing said vessel. The process makes it possible to prevent the deterioration of the solder paste such as viscosity change of the solder and the formation of solder balls which affect the printability and solder reflowability, to preserve the solder paste at room temperature and to remarkably prolong its service term.

    摘要: A clean transfer system having a first vacuum chamber with a first transfer port, a first shutter for opening and closing the first transfer port and a first connecting member surrounding the first transfer port. The first connecting member is provided with at least an exterior portion. A second vaccum chamber includes a second transfer port, a second shutter for opening and closing the second transfer port, and a second connecting member surrounding the second transfer port. The second connecting member has at least an exterior portion. A closed space is formed between the first and second connecting members, so that the first and second shutters are movable within the closed space.

    摘要: In an open joint structure for the prevention of water leakage an isobaric space is formed which has no difference between pressure in the space and ambient pressure. The open joint structure contains at least one groove 11 extending in the vertical direction formed on the exterior side of a vertical edge of a precast concrete curtain wall and which faces an opposing groove 11 of an adjacent precast concrete curtain wall. A heat barrier plate 10 with cutout portions on through holes 13 is mounted between the side walls in the grooves, thereby dividing the isobaric space into a fire-blocking isobaric space (A) between the exterior side of the wall and the heat barrier plate 10 and a radiant heat-blocking isobaric space (B) between the heat barrier plate 10 and a pair of preformed sealants 20, 20. This structure exhibits both a fire-resistant function and a watertight function in an open construction method.
