Abstract: A transmissive screen includes, sequentially from a projection side, a Fresnel lens having a condensing function, a diffusion plate for diffusing incident light, and a front-surface protective panel disposed facing the diffusion plate across an air flow layer of a predetermined interval. The front-surface protective panel partially absorbs visible light, and the visible light absorbance of the front-surface protective panel is made the highest compared with the Fresnel lens and the diffusion plate.

Abstract: Comprising a casing containing a heat insulating part, a projector as an image display unit, a screen for displaying an image issued from the projector, and cooling part (heat exchanger, compressor) for cooling the inside of the casing, the heat insulating part includes a first heat insulating part disposed in the peripheral area of the projector for insulating from heat, and a second heat insulating part disposed in the peripheral part of the screen for insulating from heat.

Abstract: A pair of spindles 2 are formed on both sides of an end of a housing body 1, and a pair of extended parts 5 facing each other, are formed on an end of a cover 4. On each opposite face of the extended parts 5, a hole 6 rotatively engaging with the spindle 2, a slope 7 guiding the spindle 2 to the hole 6 in mounting the cover to the housing body 1, and another slope 8 guiding the spindle 2 out from the extended part 5 in detaching the cover 4 from the housing body 1, are formed. Those elements enable the cover 4 to be mounted/detached to/from the housing body 1 with ease as well as free from damage.

Abstract: In a terminal connection device for a power supply circuit, a connecting lead member (4) has a straight bridge portion (4C) which includes a generally ring-like spin loop portion (5), and has an attachment terminal portion (4B) extending in a hook-shaped manner. The attachment terminal portion (4B) is inserted into a through hole (6) formed in a substrate (1) and fixedly connected by solder (7B) while the ring-like spin loop portion (5) is inserted into a corresponding slot (3) formed in the substrate (1) and securely held therein. The length (L) of the slot (3) is equal to or smaller than the outer diameter (D) of the spin loop portion (5) and the outermost of the spin loop portion comes into close contact with the inner side wall (3a) of the slot (3), and thus the finished terminal connection device can be made thin and small in size.

Abstract: The present invention relates to a document structure composing apparatus to judge a short part based upon the structure of the whole document, perform processing for complementation and compose document structure according to a desired document class. Complementation specification storage means stores the specification of complementation for document structure. Complementation means applies processing for complementation to pre-complemented document structure. Correlating rule storage means stores a rule for correlating components between different document classes. Document structure converting means converts an original document which meets the structural constraint of a specific document class to structure according to another document class according to the correlating rule. The original document is first converted from structure according to the specific document class to structure nearly according to a desired document class by the document structure converting means.
