    摘要: A rear projection screen including a Fresnel lens sheet arranged on the projection side, and a lenticular lens sheet arranged on the observation side. The Fresnel lens sheet has a lenticular lens for vertical diffusion on its light-entering side. The lenticular lens for vertical diffusion contains a plurality of convex lenses that extend horizontally, and these plural convex lenses are arranged with a constant pitch. Further, the diffusion angle of the lenticular lens for vertical diffusion continuously increases, and, at the same time, the direction of diffusion is gradually inclined to the central part side as the distance from the central part toward each of the edges on the screen surface increases. The diffusion properties (the angle and direction of diffusion) of the lenticular lens thus continuously vary between the central part and edges of the screen surface.

    摘要: A stacked structure especially useful for storing water in the underground is formed of a plurality of skeleton members. Each skeleton member includes a plurality of skeleton parts extending in one direction and situated side by side in a lateral direction perpendicular to the one direction. Each skeleton part has one top portion, and two bottom portions extending from the top portion, wherein one bottom portion in one skeleton part is connected to one bottom portion in the adjacent skeleton part. Also, each skeleton part includes top recesses formed at the top portion to be spaced apart from each other at a predetermined interval, and bottom recesses formed at the bottom portions to be spaced apart from each other at a predetermined interval. The skeleton members form upper and lower skeleton members to be vertically stacked together. The skeleton parts of the upper and lower skeleton members extend perpendicularly to each other. The bottom recesses of the upper skeleton member are located in the top recesses of the lower skeleton member so that the upper and lower skeleton members are securely assembled together.
