Abstract: A method and apparatus for accommodating mis-alignment of a piston rod in a reciprocating force delivery device is provided. A piston rod is coupled to a piston by a pivot bearing disposed around the piston rod inside the piston. The pivot bearing contacts an internal surface of the piston and provides a biaxial pivot point, which may also be triaxial, for the piston rod inside the piston. The pivot point is located near the centroid of the piston, enabling forces not aligned with the axis of the piston to be decoupled into axial and transverse components. The force decoupling avoids rotational moment on the piston, minimizing the possibility of metal-to-metal contact between components of the piston and the cylinder liner.

Abstract: A bearing apparatus for use in an floppy disc drive device motor having a sleeve bearing and a thrust bearing is provided which is characterized in that there is provided a thrust bearing having such a convex portion, a projection, or a concave portion that makes the rotation shaft of the motor inclined with respect to the center axis of the sleeve bearing. Therefore, the rotation shaft ofa motor can be forcibly inclined with the rotation shaft and the sleeve bearing being kept in contact with each other. In addition, it is possible to reduce deviation in inclination of the motor rotation shaft and to ensure electric conductance between the motor rotation shaft and the motor body. These advantages are attained by a specific structure in which a projection, a convex portion, or a concave portion is provided at the thrust bearing, and therefore, the structure is simple and requires low costs.

Abstract: A vertical post is rotatably mounted in a corner cabinet and supports a plurality of rotatable shelves which carry the cabinet door. The lower end of the post is rotatably supported by a lower bearing element which rests on a bearing member on the bottom wall of the cabinet. To enable the post and the door to be adjusted vertically, the lower bearing element is a slide supported for up and down movement in the post and having a downwardly inclined ramp on its upper end. A downwardly inclined screw extends perpendicular to the ramp and may be tightened and loosened to shift the slide downwardly and upwardly relative to the post. The head of the screw is sunk within the post to enable the shelves to be slipped onto the lower end of the post during assembly and to enable one of the shelves to pass upwardly by the location of the screw.

Abstract: The hinge-assembly to which the invention relates has a sleeve (3) located about the central section of a hinge-pin (2), and two thrust-rings (7) associated as one with the pin itself and abutting the ends (33) of the sleeve, the rings themselves housing respective seals (10). These seals (10), together with the rings (7) prevent any outflow of lubricant from the interspace between the breasted surfaces of pin (2) and sleeve (3). The assembly-procedure when uniting said hinge-assembly to the track-links involves preparation and prior lubrication of the hinge itself, followed by a pause of sufficient duration in which to check for any leaks, after which--and only after which--the links are fitted up to the pre-assembled hinge.
