    • A coated sanitary fixture having an extended deck with the coating under the deck having areas of reduced thickness of polymeric material.Preferably, the distance from the outer edge of the shell's deck to the outer edge of an area of reduced thickness is about 16% of the length of the deck of the sanitary fixture. In an alternative embodiment, the deck has at least one outermost area of reduced thickness and at least one non-outermost area of reduced thickness. The outermost area is preferably about half the height of the non-outermost area. In another preferred embodiment, the deck includes at least one outermost area of reduced thickness and at least one non-outermost area of reduced thickness. The height of the outermost area varies from a maximum height near the middle of the deck, to a minimum height near the end of the deck.

    • A dynamic pressure type bearing comprising an outer cylindrical member made of metal and a thin walled inner cylindrical member made of synthetic resin and joined to the inner periphery of the outer cylindrical member. The inner periphery of the inner cylindrical member is formed with a plurality of grooves for generating dynamic pressure. The thin walled inner cylindrical member is joined to the inner periphery of the outer cylindrical member during the moulding time by a joining means. The method of making this bearing consists of the steps of: firstly, inserting an outer cylindrical member previously provided with suitable joining means into an outer mould; inserting an inner mould provided with projections into the outer mould; pouring or injecting molten synthetic resinous material into a gap formed between the outer cylindrical member inserted in the outer mould and the inner mould already placed in the outer cylindrical member; and allowing the poured resin material to solidify to form an inner cylindrical member integrally joined to the outer cylindrical member to constitute a composite bearing of laminated outer and inner cylindrical members. The composite bearing is removed from the moulds by moving it in an axial direction away from the moulds. Preferably, the synthetic resin for forming the inner cylindrical member is a thermosetting resin.
    • 一种动压式轴承,其包括由金属制成的外圆柱形构件和由合成树脂制成的薄壁内圆柱形构件,并且连接到外圆柱形构件的内周。 内圆柱体的内周形成有用于产生动压的多个槽。 薄壁内圆柱形构件通过接合装置在模制时间期间连接到外圆柱形构件的内周。 制造该轴承的方法包括以下步骤:首先,将预先设有合适的接合装置的外圆筒体插入外模中; 将具有突起的内模插入外模中; 将熔融的合成树脂材料注入或注入到插入外部模具中的外部圆柱形构件和已经放置在外部圆筒形构件中的内部模具之间的间隙中; 并使倾倒的树脂材料固化,形成与外筒部件整体接合的内筒部件,构成层叠的外筒部件和内筒部件的复合轴承。 复合轴承通过沿轴向移动离开模具而从模具中移除。 优选地,用于形成内圆柱形构件的合成树脂是热固性树脂。

    • A lens is produced having one aspherical surface which is accurately axially aligned with a spherical or flat surface on the opposite side of the lens. The aspherical surface is produced with a mold. The mold has a molding surface having an accurate negative profile and the desired finish of the required aspherical surface.The mold is on a rotatable jig. By means of adjustment screws the mold is adjusted to correct misalignment of the axis of the molding surface and the axis of rotation of the jig. Misalignment is detected by directing a collimated light beam onto the molding surface so that it is reflected onto a screen. When the mold is rotated, the light beam moves on the screen until the molding surface is properly aligned with the axis of rotation.A preformed glass substrate has one aspherical surface of approximately the desired profile and finish and on its opposite side a spherical or flat surface. The substrate is then mounted on the jig with its aspherical surface facing and spaced from the molding surface. By means of further adjustment screws, the substrate is adjusted to correct misalignment of the axis of the spherical or flat surface of the substrate and the rotational axis of the jig. This misalignment also is detected with the collimated light beam and the screen.The gap between the substrate and the mold is then filled with a suitable liquid light transmissive polymeric material. The polymer is allowed to harden and form a molded layer bonded on one side to the substrate. The other side forms an aspherical surface of the required profile and optical finish, axially aligned with the spherical or flat surface of the substrate.
