Abstract: An air spring according to this invention enables easy and reliable adjustment of a space between stoppers. Specifically, an upper member (3) and a lower member (4) are secured to upper and lower ends of a bellows (2). Stopper faces (5) and (6) that come in contact with each other to limit the amount of displacement of the upper member (3) are formed on the upper member (3) and the lower member (4). A movable body (7) that can move vertically to adjust the height of the stopper face (6) is provided in the lower member (4). A holding body (8) is provided that holds the movable body (7) in a manner that enables vertical movement thereof. The movable body (7) is capable of relative rotation around a central axis (18) with respect to the holding body (8). On at least one of the movable body (7) and the holding body (8), tapers (32) and (41) are formed that are capable of sliding with respect to the other of the movable body (7) and the holding body (8).

Abstract: The present invention provides a rubber stopper that can set a shape suitable for mounting and set a desired stopper characteristic. Specifically, a holding fitting 3 fastened to one member by means of bolting is provided. A rubber section 4 that abuts against the other member is held by the holding fitting 3. The holding fitting 3 has a partition wall 8 to divide between a peripheral edge of a bolt hole 7 and a holding section 9 that holds the rubber section 4. A rubber side abutment surface 12 in the rubber section 4 protrudes from a top of the partition wall 8. A bored section 13 is formed near the partition wall 8 of the rubber section 4. The bored section 13 increases durability of the rubber section 4. A size of the rubber stopper 1 is reduced.

Abstract: A geared motor comprising an electric motor, a reduction gear having an input connected to a rotational shaft of the electric motor, an output shaft connected to an output stage gear of the reduction gear, which has a coupling member of resilient material attached thereto and a position sensor for detecting a rotational angle position of the output shaft, which has an input shaft connected to the output stage gear through the coupling member wherein the output stage gear has a protrusion imbedded in the coupling member so as to reinforce the coupling member and prevent it from being twisted whereby there occurs no difference between a rotational angle of the output shaft and that of the input shaft of the position sensor.

Abstract: A foamed phenolic molding composed of a core made of a kraft paper honey comb structure consisting of plate and corrugate members impregnated with a phenolic resin; and expandable phenolic composites laminated to said core, wherein the expandable phenolic composites are made of a matted fiber material formed in the shape of a plate to which phenolic resin is bonded to at least one thereof. The expandable phenolic composites and core are molded such that the expandable phenolic material fills the cells of the kraft paper honey comb structure. The molding has excellent thermal insulation and sound insulating properties as well as high strength as compared to conventional cores without sacrificing to the lightweight characteristics and workability of the quadratic surfaces.

Abstract: The invention discloses a digital position instruction signal modification device for use with a memory controlled manipulator apparatus of the type in which, during a teaching operation, a desired position of manipulator arm means is stored in memory means, and the stored position is read out during repetitive work cycles to cause the manipulator apparatus to reproduce a series of motions taught during the teaching operation. The digital position instruction or command read out from the memory means may be modified by a modifying value entered by a modifying value setting device so that all or desired digital position command or instruction signals stored in the memory means may be modified without repeating the teaching operation.
