摘要:
An uneven surface portion is formed on the inner surface of a lamp holder to thereby reduce the contact area between the inner surface of the lamp holder and a light incident face of a light guide plate. The light incident face of the light guide plate and the inner surface of the lamp holder are prevented from coming into close contact with each other due to heat transferring from cold-cathode fluorescent tubes and to the light guide plate. The heat transferring via the lamp holder to the light guide plate is intercepted by an air layer occurring between the uneven surface portion of the lamp holder and the light incident face of the light guide plate. Accordingly, it can be prevented that a part of the lamp holder sticks to the light incident face of the light guide plate of the backlight when the lamp holder is replaced.

A liquid crystal display apparatus includes a liquid crystal display panel including a display region in which a plurality of pixels are arrayed, and a planar light source device which illuminates the liquid crystal display panel from behind it. The planar light source includes cold cathode fluorescent tubes, a back surface cover, which is substantially rectangular and stores the cold cathode fluorescent tubes, and an upper surface cover attached to the back surface cover. The back surface cover has at least two extended portions, each having a main body portion extending from a side of the back surface cover and a lug portion protruding from the main body portion. The upper surface cover has supporting portions, each supporting at least the lug portion of each extended portion.

A lighting unit of the present invention includes a light guiding plate (3), a light source (2) disposed so as to face an end face of the light guiding plate, a reflector (4) disposed so as to surround the light source, a housing (6) disposed so as to have a light guiding plate-retaining portion (6a) that retains at least the reflector and is partially interposed between the light source and the end face of the light guiding plate so as to retain the light guiding plate, and a reflecting sheet (5) disposed on one of principal surfaces of the light guiding plate, the lighting unit being configured such that light from the light source enter into the end face of the light guiding plate and goes out from another principal surface of the light guiding plate. The reflecting sheet is disposed so that an edge portion (5a) is bent so as to be positioned between the light guiding plate-retaining portion of the housing and the end face of the light guiding plate.
摘要:
After first, second, and third continuous members are bonded to each other in a laminated state, they are cut together to a predetermined length for thereby producing an instant photography film unit. A predetermined number of produced instant photography film units are stacked in a stacking station, and then automatically placed into a film pack in a packaging station. An overall process of manufacturing instant photography film units that are packaged is performed automatically and efficiently.

An optical fiber amplifier with a high conversion efficiency, which is capable of using the pump light in the wavelength band that can be emitted by the laser diode, is formed by an amplification optical fiber containing thulium at least in a core, to which a signal light is to be entered, and a pump light input unit configured to enter at least one pump light with a wavelength in a range of 1320-1520 nm, or more preferably 1320-1480 nm, into the amplification optical amplifier.
摘要:
A photographic film cassette manufacturing apparatus, has a perforator for providing a long film with perforations and a cutter for cutting the long film into individual filmstrips to be contained in the film cassette driven synchronously with transport of the long film. A magnetic recording head for recording data on a magnetic recording layer of the long film is driven in synchronism with the perforator and the cutter. The long film is transported in a first direction before being cut into the individual filmstrips. In cooperation with the cutting, a trailing end of the individual filmstrip in the first direction is moved in a direction which is reverse to the first direction to secure the trailing end to the spool. A cassette shell consisting of a pair of shell halves is temporarily assembled by mating the shell halves together while containing a spool inside the shell halves, and thereafter opened to an extent that confining elements still confine the position of flanges of the spool. The trailing end of the filmstrip is inserted into the opened cassette shell and secured to the spool.
