Abstract: In cylinder chambers 14 and 15 of a housing 10 constituting an actuator main body 13, racks 17 and 18, to both end portions of which piston portions 17a and 18a are provided, are reciprocably incorporated. A pinion 25 meshing with the racks 17 and 18 is provided on a rotary shaft 24 rotatably mounted to the housing 10. An inner ring 32 is incorporated inside an outer ring 41 fixed to the housing 10, and the inner ring 32 is attached to the rotary shaft 24 and rotates and drives a swung member. Rollers 43 serving as rolling elements are incorporated between an inner peripheral surface of the outer ring 41 and an outer peripheral surface of the inner ring 32, and the rotary shaft 24 and the inner ring 32 are rotatably supported by the outer ring 41 via the rollers 43.

Abstract: A handling apparatus mounted on a moving member for holding, conveying, and installing a workpiece has a floating plate attached for radial movement to an apparatus body 10 connecting with the movable member, and a workpiece holding device for holding the workpiece on the floating plate. A lock plate is provided for fastening the floating plate to the apparatus body in a radial direction, A fastening piston is coupled to the lock plate through a fastening rod, and the floating plate can be fastened at any position. An aligning piston on which a tapered surface is formed is mounted on the apparatus body for reciprocation. The tapered surface of the aligning piston engages an aligning hole of the floating plate to return the floating plate in the radial direction to an origin position.

Abstract: A floating plate 41 is attached radially movably to an apparatus body 10 attached to a movable member, and a workpiece holding device for holding a workpiece is mounted on the floating plate 41. A lock plate 33 for fastening reciprocably the floating plate 41 to the apparatus body 10 in a radial direction is provided, and a fastening piston 31 is coupled to the lock plate 33 through a fastening rod 32, and the floating plate 41 is fastened at any position. An aligning piston 47 in which a taper surface 51 engaged with an aligning hole 52 of the floating plate 41 is formed is mounted reciprocably on the apparatus body 10 in the radial direction, and the floating plate 41 is returned to an origin position by the aligning piston 47.

Abstract: For treating bilge containing solid matters and emulsion securely, an oily water separator includes a first treater 1 for separating oil ingredient roughly from bilge by gravity separation and removing fine suspended matter from the bilge by sand filtering, and a second treater 10 for separating and removing oil ingredient remained in the bilge treated by the first treater. The first and second treaters 1, 10 are connected directly by a feeding pipe 8. The first treater 1 includes an oil discharge portion 5a above an oily water, inlet 2 and a filtering sand layer 3 below the oily water inlet 2. The second treater 10 includes a coalescer 19 in a lower room 29 to communicate with the upper room.
