摘要:
A sidelight type light source device increases the quantity of light in a corner portion of a light guide plate at low cost while meeting a demand for picture frame narrowing. An incident surface receives light from a stick-shaped light source. The incident surface includes a first incident surface its center a pair or second incident surfaces at the ends of the first incident surface. The second incident surfaces are formed on a corner portion in a width direction of the light guide plate. The second incident surfaces are set back from the first incident surface taken as a reference. Accordingly, a light introducing route is defined between the second incident surface and rubber blocks at the ends of a fluorescent light source. Light from the fluorescent lamp passes along the light introducing route where it is directly incident on the second incident surfaces of the light guide plate.

In a flat surface illumination device or a liquid crystal display panel, with an aperture disposed in a frame or a case, comprising a circumferential section in which a central section receiving and supporting the light guide and the like is removed, a warp preventing means is formed in such a manner to cross the aperture. The warp preventing means comprises a long and narrow zonal thin plate in which two or more beading processes are performed.

An acoustic damper is fixed to a vibration source to be provided along an outer surface of the vibration source, forms a passage that takes in air vibration generated by the vibration source, and is provided with an acoustic portion having a partition member closing the downstream side of the passage with respect to the propagation of the air vibration to serve as resistance against the air vibration, in which the acoustic portion allows air vibration to propagate in a reverse direction, and has partition members arranged so as to serve as resistance against the air vibration in respective directions. This allows to prevent from generating stress due to pressure fluctuation caused when reducing vibration, and to achieve a relatively compact size.

An object is to provide a combustor that requires a small mounting space for an acoustic damper, that can achieve size reduction, and that can improve the ease of maintenance. A combustor (5) of the present invention includes a combustion cylinder (19) that defines a combustion area (23) therein and an acoustic damper (31) that has a damper cover having an acoustic-damper resonance space communicating with the combustion area (23). The damper cover is provided along the combustion cylinder (19) so as to extend in a direction intersecting an axial direction (L) of the combustion cylinder (19).

A rotating blade body is provided that can restrain vibrations of rotating blades effectively. The rotating blade body comprises a rotor disc, a plurality of rotating blades being assembled so as to extend from the outer circumference of the rotor disc in a radial pattern, and sealing pins extending along the direction of the rotating shaft in the gaps between the platforms of the rotating blades being adjacent in a circumferential direction. The sealing pins have a through-hole made therein, penetrating axially from one end surface to the other end surface.

The characteristics of a heat radiation member used in a semiconductor module are improved.A heat radiation member (10A) including an aluminum type member (20) which contains aluminum and a copper type member (30) which contains copper, which is embedded in the aluminum type member (20), and sides of which are enclosed by the aluminum type member (20) is formed. A semiconductor element is thermally bonded to the heat radiation member (10A) to fabricate a semiconductor module. The heat radiation member (10A) includes the aluminum type member (20) and the copper type member (30). As a result, it is possible to realize light weight while ensuring certain heat radiation. In addition, the copper type member (30) is enclosed by the aluminum type member (20). Accordingly, the strength of the heat radiation member (10A) can be increased.
