Abstract: A magnetically-attracting crawler moving device has a magnetically-attracting traveling mechanism including a source device of magnetic force provided with a pair of magnets and a yoke disposed on the backside of the magnets or behind the magnet; a crawler belt rotationally running with drive portion thereof in non-contact with the source device of magnetic force; and a guide in contact with the pair of magnets and the yoke and on which surface the crawler belt slides, wherein the drive portion of the crawler belt protrudes from the source device of magnetic force and the guide to travel.

Abstract: Provided is an inspection robot that is self-propelled on piping, measures moisture contained in a lagging material using a mounted inspection device, for example, a neutron moisture meter, and detects risk of corrosion. The inspection robot includes a main frame 1 including a recessed part 17 fit onto an outer circumferential surface of piping P, a main frame drive mechanism (first drive mechanism) D1 that causes the main frame to advance/retract in an axis direction of the piping, a revolving member 32 supported in an advanceable/retractable manner along an arc-shaped locus in the recessed part of the main frame, a revolving member drive mechanism (second drive mechanism) D2 that moves the revolving member, and an inspection device mounted on the revolving member.

Abstract: The invention provides an apparatus for compressively molding cushioning material using a quadrangular cylindrical molding box having an end side closed by a receiver mold, whereas the other end of said molding box receives supply of dry raw material consisting of fiberized paper or pulp by a volume corresponding to several times the actual volume of a molded body. A compressive mold inserted from the other end of the molding box is shifted to one-end side of the molding box to compress supplied raw material between a receiver mold. Simultaneously, a core member is retreated to a predetermined position of said one-end side in association with the shifting movement of the compressive mold. As a result, the core portion having thin thickness and the interior of the core member can securely be compressed and molded with even density.
