  • Patent number: 6917755
    Abstract: An apparatus for supporting a substrate is described that has a ball adapted to minimize damage between the substrate support and the substrate supported thereon. In one embodiment, an apparatus for supporting a substrate includes ball disposed on an inclined ball support surface. The ball support surface is adapted to bias the ball toward one side of the ball support surface thereby providing space for the ball to roll as the substrate supported thereon changes in length when exposed to thermal influences. In another embodiment, the apparatus further comprises a cage adapted to capture the ball to the ball support surface.

  • Patent number: 5318365
    Abstract: In this rolling guide unit, a slider is provided on a track rail so that the slider can be moved slidingly in a linear direction, and a circular bore is formed in a casing constituting the slider. A cross-sectionally V-shaped outer annular raceway surface is formed on the circumferential surface of the circular bore, and a rotary body consisting of lower and upper rotary bodies is fixed rotatably in the same circular bore. The casing constitutes a common part having both a function of making a linear movement and a function of making a rotational movement. This enables the height of the rolling guide unit to be reduced to as great an extent as possible, and an accumulated error due to an assembling operation to be minimized, so that a highly accurate guide machine can be provided.

  • Patent number: 5005987
    Abstract: There is provided a rectilinear motion rolling guide unit comprising: a long track rail having an almost I-shaped cross section; a casing having an almost inverse U-shaped cross section; and rolling elements interposed between the track rail and the casing. The casing is arranged so as to ride over the track rail by a concave portion formed in the central lower portion of the casing. Upper and lower corner portions of both upper projecting portions of the track rail are chamfered to form inclined surfaces, thereby forming two upper and lower rail side track surfaces, respectively. Two upper and lower casing side track surfaces are formed on the inner peripheral surfaces of the concave portion of the casing at positions corresponding to the two upper and lower rail side track surfaces. A number of rolling elements are interposed between the corresponding track surfaces on the rail and casing sides, respectively, thereby allowing a relative slidable motion between the track rail and the casing.

  • Patent number: 4863289
    Abstract: A seat track assembly is disclosed that comprises a fixed channel member and a sliding channel member disposed on the fixed channel member. The channel members are interfitted with generally U-shaped engagement members. A first ball bearing assembly is disposed at one vertical position between the two channels, and a second disc-shaped bearing is disposed at a lower vertical position between the U-shaped flanges of the two channels. The second bearing provides support in both the vertical and horizontal directions to prevent seizing between the two channels. The second bearing is resilient and acts to prevent seizing of the two channels by providing a resilient force vertically in opposition to the upward force created by the seat back when the seat is unoccupied and also provides resilient forces horizontally to prevent seizing due to twisting of the channels.
