摘要:
The light source device of a display device according to the present invention has an optical waveguide, a cone sheet, and a light source disposed along the side surface of the optical waveguide. The light-emitting surface of the optical waveguide is flat, and a tilted surface that is tilted towards the light source with respect to the light-emitting surface is formed on the light-diffusing surface. The cone sheet has a flat plate and a plurality of circular cones arranged two-dimensionally on the light-incident surface of the flat plate. The central axes of the circular cones are parallel to each other. The invention provides a light source device that can be made thin and is capable of increasing the directivity of emitted light in two dimensions.

This invention relates to a method of molding a double-wall bottle consisting of an outer bottle (12) and an inner bottle (14). A outer bottle (12) is first formed from a first preform by biaxial Stretch blow molding. After this molding step, a plurality of air vent holes (24) are formed in a biaxially orientated region of the outer bottle (12). Next, a second preform (70) and the outer bottle (12) are set together within a first blow cavity mold (100). Subsequently, the inner bottle (24) is formed by biaxial stretch blow molding from the second preform (70) while the air within the outer bottler (12) is expelled through the air vent holes (24). Circumferential concave ribs (22) are formed around the entire circumference of the outer bottle (12), and at least one of the air vent holes (24) is formed in a region either inside or outside the region in which the circumferential concave ribs are formed.

A method for processing the surface of a work roll, comprising forming a pattern coated with a cured product of a photosensitive resin composition on the surface of a work roll only at a predetermined portion, chemically etching the surface of the work roll at the remaining uncoated portions and peeling the cured product to form an uneven pattern on the surface of the work roll, wherein the composition comprises a visible light curable photosensitive resin composition and is cured by visible light irradiation.
摘要:
The present invention provides an apparatus for stretch blow molding a preform into a hollow container having a heat-resistant property, including a heatable blow mold for forming the preform located therein into a hollow container by a biaxial stretching and blow molding process, and a heat setting mold for heat setting the hollow container. The apparatus includes a stretching rod for longitudinally stretching the preform when the stretching rod is forwardly moved in engagement with the inner bottom of the preform. The stretching rod has a cooling medium introducing tube centrally located therein with an outlet port adapted to introduce cooling medium into the interior of the hollow container. The cooling medium introducing tube is surrounded by thermal insulation.

According to one embodiment, an image display apparatus includes a light source, a modulation unit, a first array and a second array. The modulation unit modulates intensity and a color of the light to generate beams corresponding to each of modulated pixels included in a modulated pixel group. The first array is formed by juxtaposing a plurality of first deflection elements each having a generating line parallel to a vertical direction of the modulated pixels. The second array is formed by juxtaposing a plurality of second deflection elements each having a generating line tilted by an angle represented by tan−1(α×m/n) with respect to a generating line of the first deflection element.
