To provide a levitation air plate that can be easily manufactured and can float a substance being conveyed such as a glass while maintaining its high rigidity and controlling a floating amount in high accuracy. A levitation air plateprovided with: a top platein which a plurality of air ejection holesand suction holespenetrating from an upper surfaceto a lower surfaceare arranged in alternating fashion as viewed from the upper surface, the top platehaving a counter-bored portionon the lower surface side of each of the plurality of air ejection holes; an orifice sheethaving a plurality of orificespenetrating from an upper surfaceto a lower surfacein positions corresponding to the counter-bored portions of the top plate, and having communicating holescommunicated one-to-one with the suction holes of the top plate and penetrating from the upper surface to the lower surface; and bottom side plateshaving an air supply channeland an air supply holefor supplying air to all of the orifices drilled in the orifice sheet, and an air suction channeland a suction holefor suctioning air from all of the communicating holes communicated with the suction holes.

A spherical bearing includes an outer ring formed integrally with a rod end, an inner ring having a spherical outer peripheral surface arranged in face-to-face relation with the inner peripheral surface of the outer ring, and a flexible lubricating sheet disposed between the inner peripheral surface of the outer ring and the spherical outer peripheral surface of the inner ring. Respective central portions in both annular areas of the flexible lubricating sheet which are respectively defined between an axial center of the outer ring and one annular end of the inner peripheral surface of the outer ring and between the axial center of the outer ring and another annular end of the inner peripheral surface of the outer ring are made to undergo plastic flow and are formed to be thinner than a remaining portion of the flexible lubricating sheet.

A door hinge assembly is disclosed, which comprises a door hinge assembly for pivotally connecting a door to a fixed structure. The assembly comprises a first wing member secured to the fixed structure, the first wing member having first aligned bores formed therethrough; a second wing member secured to the door, the second wing member having second aligned bores formed therethrough, the first and second wing members being so arranged that all of the first and second aligned bores are aligned; a pivot shaft passing through the aligned first and second bores to pivotally connect the first and second wing members; plastically deformable bushes respectively disposed in the second bores while rotatably receiving therein the pivot shaft; a first structure for suppressing rotation of the pivot shaft relative to the first bores; and a second structure for suppressing rotation of the bushes relative to the second bores. Each bush includes a tubular part intimately and tightly received in the corresponding one of the second bores, and a first flange part integrally formed on one end of the tubular part and intimately contacting with one surface of the second wing member. The bush further includes a slit which extends axially throughout the tubular and flange parts thereby providing the bush with circumferentially opposed terminal end portions.
