Abstract: The present invention provides a plastic lens which can simplify the installation, can enhance the forming accuracy and can exhibit extremely small optical irregularities. Molds having a planned combination are heated, using at least one pre-numerically controlled automatic chucking transport device and/or manually, the molds are constituted to be sequentially overlapped in accordance with the combination. First of all, an optical thermoplastic resin molten material having an extremely small agitation flow is placed on a forming surface of one lower mold. Subsequently, a forming surface of another upper mold is brought into contact with the resin molten material by inclining the posture of the upper mold, and both molds are made to approach each other to define a given distance therebetween so as to form a lens by pressing the resin molten material.

Abstract: Methods and apparatuses for providing access to data in a cluster database are described. Embodiments of the invention include identifying situations in which many nodes require relatively equal access to a data block, and taking appropriate measures to improve the performance of the system in these situations. For example, a node may automatically downgrade its lock from an X lock to an S lock as soon as it has finished a modification of the data. S locks are sent to other nodes in the system as soon as a modification is complete. Modifications to the data are also sent to other nodes in the system as soon as a modification is complete. Depending on the size of the data modification, the entire data block may be sent, or only the modifications to the data may be sent.

Abstract: A cut that widens a through hole of an end portion of a headliner interior material breaks when an airbag is deployed, and is formed on an exterior-side of the end portion. The end portion of the headliner interior material is in close contact with a surrounding member provided around the end portion. In addition, an accessory is passed through the through hole and fixed to a body, while the end portion of the headliner interior material is held to the accessory around the through hole. When the airbag installed folded on the exterior side of the headliner interior material is deployed, the airbag deploys into a cabin from between the end portion and the surrounding member.

Abstract: A light alloy wheel for two-wheeled or four-wheeled vehicle comprises an outer rim having a tubular rim part that includes: a bead seat; a hump; a slope wall; an ornamental wall; and a cavity defined by these four walls. Cross-sectional area and geometric moment of inertia are calculated for the tubular rim part. Thus provided is a wheel having lighter weight and higher rigidity and fashionability compared to a wheel only having a solid rim part consisting of the bead seat, a hump and a slope wall and not having the ornamental wall or cavity. The solid rim part has a standardized shaping construction with respect to inclination, dimensions and wall thicknesses, in conformity mainly with design specification of a tire.

Abstract: A novel microorganism such as a Bacillus sp. OYK-01-600 (FERM BP-6394) which has no induction period, immediately undergoes exponential growth, and is nonhemolytic. The bacteria have antimicrobial activities against toxic bacteria such as Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus, pathogenic Eschericia coli including O-157, Legionella pneumophila, and Klebsiella pneumoniac. The increased growth rate can inhibit bacteria which emit an ofensive odor and many noxious infection bacteria.

Abstract: Lenses are provided in an assortment of frequently used prescriptions and are preground to a desired final contour. The lenses are optionally provided with a lug, temple and modern and with a split bridge member attached thereto to provided a half eyeglass assembly. Alternately, the parts may be provided unassembled. Proper lenses are selected on the basis of a prescription by a consumer and are assembled by the consumer to form a completed pair of eyeglasses. A bridge assembled from the split bridge members is adjustable to set a desired interpupillary distance. The positions of holes for attaching the bridge and lug to the lenses are line-symmetrical with respect to a vertical axis of each lens so as to allow the lens to be used as either a right or left lens.

For this purpose, a stamper 108 having a concave-micro-granular transfer-molding surface transfer-molded from a convex-microgranular surface comprised of SiO.sub.2 or the like and varying continuously in the index of refraction is used to reproduce the convex-microgranular surface.

Abstract: The present invention relates to an auxiliary driving device for the patterning device for a warp knitting machine, including a desired number of movable bodies each having at least a portion thereof formed as a guide point, the movable bodies being disposed in a guide path so that they are movable on the basis of driving means installed thereon, patterning being effected in that the individual guide points are moved by desired amounts of displacement in optional directions on the basis of signals transmitted from an electronic control section to the driving means for the individual movable bodies and are thereby positioned. The invention provides a device and method enabling the movement of the movable body to follow even a high speed rotation, and is characterized in that it includes auxiliary driving means for adding to the driving force from the driving means during start and movement involved in the lapping caused by the movable body.

Abstract: A patterning method and device has yarn guides for guiding pattern yarns in a warp knitting machine and divisional fall plates for knitting pattern yarns in a fall plate structure individually drive-controlled through drive devices. The device comprises any number of moveable bodies having yarn guides, the bodies being installed for movement along a row of knitting needles by the drive devices. For patterning, the moveable bodies are moved through a desired distance along the row of knitting needles so as to be positioned for patterning, thereby providing a patterning zone for pattern yarns corresponding to the number of yarn guides. Thus, it is possible to effect a free varigated patterning which is comparable with the patterning effect provided by the Jacquard control.
