A picture generation apparatus includes: a light source substrate on which a light source is mounted; an optical member through which light emitted from the light source is transmitted; a display device configured to form, by the light transmitted through the optical member, light for generating a predetermined picture; a heat sink configured to dissipate heat generated from the light source substrate; and a lens holder configured to hold the optical member. The lens holder includes first engagement portions, and the heat sink includes second engagement portions. Each of the first engagement portions and a respective one of the second engagement portions are fixed to each other, so that the light source substrate is positioned and fixed in a state of being interposed between the lens holder and the heat sink.

A vehicular resin molded article is formed by solidifying a molten resin filled in a cavity of an injection mold and having a concave gate mark formed by a valve pin and remaining thereon in which L/T is 190 or more where L is a flow distance of the molten resin from the gate mark to a filling terminal and T is a maximum thickness. When the valve pin is moved to the cavity side and is pressed against the molten resin, since the contact area of a tip end portion with respect to the molten resin in the vehicular resin molded article increases and the temperature of the tip end portion in the valve pin tends to decrease, the portion of the vehicular resin molded article where the valve pin is pressed against is sufficiently solidified and string drawing or silver streak is less likely to occur.

Vehicular resin molded article

A resin molded product produced by injection molding includes: a gate mark formed on a non-design surface; and a step provided so as to intersect with a flow of a resin injected from a gate. When a flow distance of the resin from the gate mark to an end portion of the resin molded product is L [mm], and a thickness of the resin molded product is t [mm], the resin molded product is configured to have L/t of 185 or more, and a tangential angle of the step is 5&#xb0; to 30&#xb0;.

Resin molded product

A method for manufacturing an optical component having an optical surface includes: injecting a molten resin into a cavity; curing the molten resin to form the optical component; and taking the optical component out from the movable mold by moving the movable mold away from the fixed mold, and piercing a part of the optical surface (first incident surface) of the optical component attached to the movable mold by the protruding pin, and then wherein a tip end face of the protruding pin includes: a first surface; and a second surface having an area smaller than an area of the first surface, and extending continuously from the first surface in a curved form, the second surface being located on at least a part of an outer circumferential edge portion of the tip end face, that is, a tip end in the first direction.

A projection lens formed of a light-transmitting resin including an incidence part on which light is incident, an emission part, a peripheral edge portion, and a thick part. Light is incident on the incidence part. The emission part emits the light incident from the incidence part. The peripheral edge portion is provided at a boundary between the incidence part and the emission part. The thick part is provided at a part of the peripheral edge portion, made thicker in an optical axis direction than other parts of the peripheral edge portion and having a gate mark formed at least on a part of an outer peripheral surface of the thick part.

Projection lens with peripheral thick part and vehicle lamp provided with the same

A vehicle lamp according to an aspect of the present invention includes a light source, a metal light-source stage including a light-source mounting portion, and a lens member that emits light from the light source toward the front of the lamp. The light-source stage includes a support portion for the lens member. The lens member includes a leg projecting toward the light-source stage and having an end that is supported by the support portion. The support portion includes three projections that abut the leg in a state in which the leg is supported by the support portion and position the lens member in a direction of an optical axis. The three projections are positioned relative to one another such that at least a portion of the light source lies in an extension range of a triangle with vertices given by the three projections.

An image-receiving sheet element comprising an image-receiving layer provided on a flexible substrate and a removable cover sheet, wherein said cover sheet comprises a low density copolymer containing 30% by weight or more of a linear polyethylene, is described. This image-receiving sheet element shows improved slip properties and a good workability, and little deterioration in transfer properties upon prolonged storage. Furthermore, it scarcely suffers from any caused by static electricity when the cover sheet is peeled off from the image-receiving sheet.
