摘要:
An object of the present invention is to prevent the dhesion of particles such as fine iron powders onto a glass substrate upon the production of a glass substrate for an information recording medium. To attain the above object, any one of the following means is adopted: (1) at least one of the production, inspection, packing and filling steps of the glass substrate for an information recording medium is carried out under a clean atmosphere which does not permit the adhesion of particles; (2) at least a wall surface of a chemical reinforcement tank containing a chemical reinforcement liquid therein and/or said retaining means which is contact with the chemical reinforcement liquid is formed of a stainless alloy having corrosion resistance in a high-temperature region as high as the heating temperature of the chemical reinforcement liquid; (3) a means for trapping fine particles existing in the chemical reinforcement liquid used in the chemical reinforcement step is provided; and (4) the glass substrate is washed with hydrochloric acid.

The surface of a glass substrate withdrawn from a chemically strengthening treatment liquid is processed with a heated acid (for example, a thermal concentrated sulphuric acid at a temperature of over 100.degree. C., or a water soluble organic solvent such as glycerol or polyethylene glycol). Consequently, precipitated fused salt can be effectively removed without damaging the glass substrate and the change in quality of the glass surface can be also prevented at a high level.

A light projection apparatus that can produce an elongate light projection pattern is provided. The light projection apparatus includes a fluorescent member which is excited with exciting light and a light projecting member which reflects or transmits the light emanating from the fluorescent member to project it outside. The fluorescent member includes an irradiated region which is irradiated with the exciting light, and the length of the irradiated region in a first direction is greater than its length in a second direction.

A light-projecting device according to the present invention includes a plurality of light source units including (i) a light emitting section that emits light upon receiving a laser beam and (ii) a reflector. Each of the light source units project light to a corresponding one of light-projected spots which is a region to which light is projected in an illuminated region in a partitioning manner, and the illuminated region is formed by combining a plurality of the light-projected spot.

A vehicle front structure includes: a bumper face disposed at a vehicle front end; and a lower grill disposed at a bumper opening section of the bumper face. The bumper face includes: a hook cover (20), after formed integrally with the bumper face within the bumper opening section, separated from the bumper face; and a hook cover holding mechanism (26) formed within the bumper opening section integrally with the bumper face to detachably fix the hook cover (20). The hook cover (20) includes: a cover body section (40) for closing a hook cover attachment portion in the bumper face; and a cover snap-fit claw (32) for snap-fitting onto a bumper engaging portion in the hook cover attachment portion. The hook cover holding mechanism (26) includes a hold latch nail (34) for engaging with the cover snap-fit claw (32) by resilient deformation of the hook cover (20).

A light projection unit is provided that can reduce the production of a portion where the light density is excessively increased on a fluorescent member. This light projection unit includes: a light collection member that includes a light entrance surface and a light emission surface which has an area smaller than that of the light entrance surface; a fluorescent member that includes an application surface to which the laser light emitted from the light collection member is applied and that mainly emits fluorescent light from the application surface; and a light projection member that projects the fluorescent light. The light emission surface of the light collection member is arranged a predetermined distance from the application surface of the fluorescent member.

An object of the present invention is to provide a subscriber-side device, which can generate accurate time information and can synchronize a time with other device even if a power supply of a portion that receives a downlink signal is in an OFF state, and to provide an optical transmission system including the same. The subscriber-side device of the present invention corrects and outputs free-running time information, which is generated based on a free-running clock signal, by a time correction value generated based on a frequency deviation between a synchronization clock signal and the free-running clock signal. When the downlink signal sent from the station-side device is in a signal interruption state of being incapable of recognizing or receiving the downlink signal, the subscriber-side device corrects and outputs the free-running time information by a time correction value generated before the downlink signal turns to the signal interruption state.
