摘要:
An illumination device including a plurality of illumination areas, each of which is individually controllable, includes a plurality of light-emitting devices disposed in a matrix pattern in each of the illumination areas where emission colors are disposed in a different manner between adjacent rows and between adjacent columns. Consequently, the emission of uneven luminance or uneven color is prevented from occurring in boundary portions of each of the illumination areas.

The invention provides a flame-retardant processing agent capable of imparting durable flame retardance to polyester-based fiber products without using halogen-based flame retardant. The flame-retardant processing agent is obtained by dispersing at least one phosphoric acid amide selected from the group consisting of 1,4-piperazinediyl bis(diarylphosphate), diaryl aminophosphate and aryl diaminophosphate as a flame retardant in a solvent in the presence of a nonionic surfactant or an anionic surfactant.

An illumination device according to the present invention includes a light source; and a lightguide element including an incidence surface for receiving light emitted from the light source and an outgoing surface from which the light incident from the incidence surface goes out. The lightguide element includes a polarization selection layer for causing light of a specific polarization direction (first polarized light), among the light incident from the incidence surface, to selectively go out from the outgoing surface, and a polarization conversion layer for converting second polarized light, polarized in a different direction from that of the first polarized light, into the first polarized light. The polarization selection layer reflects the first polarized light substantially only toward the outgoing surface.

Multiple epitaxial layers are grown on the front side of a p silicon substrate and no layers are grown on the other side. Among the multiple epitaxial layers the one in contact with the silicon substrate is a first p+ epitaxial layer. Since the epitaxial layer is in contact with the p+ layer, gettering can be efficiently done also in a low-temperature device manufacturing process, thereby improving the manufacturing yield of an epitaxial wafer. Therefore the manufacturing cost of an epitaxial wafer is reduced.

In a photo film loaded in a lens-fitted photo film unit, a bar code is recorded at the time of manufacturing. The bar code represents various kinds of information, including known film type information. The film type information further contains flashless information, which indicates that the photo film is for the photography without emitting flash light. In printing, the bar code visualized by developing is read by a printer. When the photo film is judged that the flashless information is provided, a color correction is performed with using the LUT of the color correction specified for a flashless photography.

Adapter covers are prepared for designating a sepia photofinishing, a monochrome photofinishing, a color photofinishing, and a frame-adding photofinishing. A user selects one of the adapter covers that designates the user's intended photofinishing, and attaches it to the lens-fitted photographic film unit. The lens-fitted photographic film unit is provided with three photography data optical paths for recording three bit marks as optical codes. The photography data optical paths are selectively covered by the adapter cover, and the optical code corresponding to the type of the adapter cover is recorded on a photographic film. A photographic print is produced by the photofinishing designated by the optical code recorded correspondingly to each picture frame.

A thin film manufacturing system, wherein a stage for placing a substrate thereon is disposed within a vacuum reactor and a gas head for supplying a film forming gas to a central area on a top face of the vacuum reactor is arranged so that the gas head is opposed to the stage. A cylindrical sleeve member is disposed and comes in close contact with a side wall of the stage to surround a periphery of the stage. The height of the stage can be established at the position where the volume of a second space formed below the stage and connected to a vacuum discharge means is larger than that of a first space formed above the stage, in such a manner that an exhaust gas is isotropically discharged from the first space without causing any convection current therein through the interstice between the sleeve member and an inner wall surface constituting the reactor.

A front-illuminating device of the present invention, which is placed over the entire surface of an object to be illuminated such as a reflection-type liquid crystal display device when it is used, is provided with a light source and a light-directing body. The light-directing body has an incident surface on which light from the light source (light-source light) is made incident, a first light-releasing surface for releasing the light toward the object to be illuminated, and a second light-releasing surface which faces the first light-releasing surface and releases reflected light from the object to be illuminated. The second light-releasing surface is formed into a step shape in which slanting portions and flat portions are alternately placed. The light source light, released from the first light-releasing surface to the object to be illuminated, is reflected by the object to be illuminated and the reflected light is allowed to reach the observer from the first light-releasing surface through the flat portions. In this case, among the light-source light rays, the light components progressing in parallel with the flat portions are reflected by the slanting portions and directed to the object to be illuminated. Consequently, the present invention makes it possible to provide a brighter front-illuminating device in which the efficiency of use of the light-source light is improved.

Disclosed is a lens-fitted photographic film unit containing a roll of unexposed photographic film. The lens-fitted photo film unit uses a specific battery of a different size or shape from conventional standardized batteries. A hollow protrusion is formed in a battery holding room. A hollow of the hollow protrusion joins with a dark room for the photographic film. If the hollow protrusion is cut away with the intention to put a conventional battery in the battery holding room, the light-tightness of the dark room is destroyed. When a cartridge chamber bottom lid is opened to remove a film cartridge, an interconnection lever transmits the opening movement of the lid to a sliding plate. Then the sliding plate turns a charge switch of a flash circuit ON, and locks the charge switch in the ON position.
