A method of producing a glass article includes holding a carrier having a circular shape, in which a glass substrate having a circular shape is retained, with an upper surface plate and a lower surface plate; and polishing the glass substrate by rotating the carrier with respect to the upper surface plate and the lower surface plate, to obtain the glass article. The glass substrate is disposed in the carrier such that, in a top plan view, a center of the carrier is included in a region of the glass substrate, and a center of the glass substrate is shifted from the center of the carrier.

Glass article and method of producing glass article

A glass member includes a recessed portion, wherein in cross-sectional view, an angle formed between a principal surface of the glass member and an edge face of an opening of the recessed portion is 90 degrees to 130 degrees.

The reflective surface of a reflector 16 is divided through steps into a plurality of vertically elongated reflective surface elements. In each of those reflective surface elements, the light incidence section to which the output light of a light source bulb is applied is made up a convex cylindrical curved surface and a concave cylindrical curved surface which are arranged substantially in parallel with the step adjacent to the light incidence section. Accordingly, when the lamp is turned on, and the reflector is observed from the front, the light incidence sections function as follows; that is, the apex portions of the cylindrical curves surfaces look glittered as bright sections. Therefore, the reflective surface looks more sparkling.

Vehicle signal lamp

A vehicular lamp including a lamp body formed from a synthetic resin, a front lens coupled to a front opening of the lamp body, and a light source, wherein the lamp body is provided with a bulb holder part for holding the light source bulb, and a cover section of the bulb holder part is molded integrally with an outer peripheral part of the lamp body by different materials from each other.

Vehicular lamps and method of molding a lamp body of vehicular lamps

An optical axis adjustment structure which includes an aiming adjustment screw having a ball part disposed at one end thereof for receiving and being supported by a movable part of a lamp or the like, an intermediate part screw-engaging with a nut member fitted in a stationary part of a vehicle body or the like, and an operating part disposed at the other end thereof for a rotational operation, and the outer dimension of the operating part of the aiming adjustment screw is designed to be larger than the threaded intermediate part of the screw and the outer diameter of the ball part is larger than the diameter of the threaded part of the screw, while the nut member is integrally molded with the aiming adjustment screw at the intermediate part thereof.

Optical axis adjustment structure for vehicular lamps and method for

A vehicular lamp which includes a lamp body and a wedge-base bulb which connects to a lead wire, in which a base member of the wedge-base bulb is held by contact holding pieces of a contact terminal which is securely held by the lamp body and penetrates the lamp body in the front-rear direction thereof, so that the wedge-base bulb is mounted on a front surface of the lamp body, and the lamp is characterized in that the contact terminal is of a box-type and formed integrally with the lamp body.

Vehicular lamp

In a color changing lamp equipped with a bulb 4 emitting a color of light, a glove with a different color from the color is selectively located on the covering position and exposure position of the bulb 4 in order to emit the different color of light. The current supply for the bulb 4 is stopped while the glove is selectively moved, thereby preventing different colors of light in a mixed state from being emitted on the way of exchange.

Color-changing lamp for vehicle

An aiming level device for a motor vehicle headlamp which has a short longitudinal length, requires a small number of components, and is simple to assemble. The inventive aiming level device includes a body member or base, a bubble vial supporting frame pivotable with respect to the body member, and a zero-point adjusting screw for holding a sideward extending part of the supporting frame. The bubble vial supporting frame, which is formed by cutting and bending a single thin metal plate, holds the bubble vial with parts continuously formed at a side region of the front-rear extending region of the frame to support the bubble vial at front and rear portions thereof, and the front and rear end portions of the front-rear extending region are held by the zero-point adjusting screw so that it is adjustable upward and downward by rotating the screw.

Aiming level device for motor vehicle headlamp

A motor vehicle headlamp which employs a discharge lamp as its light source, and which is combined with a clearance lamp. The clearance lamp is provided in the front end portion of a space defined by a lamp body in such a manner that the clearance lamp is adjacent to the reflector, and a ballast circuit for energizing the discharge lamp is provided behind the clearance lamp inside the lamp body.
