摘要： A transmission screen is capable of preventing the reduction of contrast in images due to external light such as emitted by internal lighting fixtures. The transmission screen includes a Fresnel lens sheet having a front surface facing the viewer and provided with Fresnel lens elements, and a shading sheet 13 placed contiguously with the front surface of the Fresnel lens sheet. The shading sheet 13 is provided with shading elements 22 for absorbing external light fallen on the front surface of the shading sheet 13 and reflected in a total reflection mode by the back surface of the Fresnel lens sheet facing a projection light source toward the viewer. Preferably, the shading elements 22 transmit at least external light fallen on the shading sheet at an incident angle θ satisfying a condition expressed by: θ

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 containing 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 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 the edges of the screen surface.

摘要： A film stretching structure holds a non-self-supporting film, sheet or the like taut so that the film, sheet or the like may not crease or slacken. The film stretching structure comprises a frame structure having, as principal components, a quadrangular outer frame having two opposite side members for supporting a film, a sheet or the like thereon, and an inner frame having side members substantially parallel to those of the outer frame, respectively, and disposed inside the outer frame so as to form gaps between the side members of the outer frame and the corresponding side frames of the inner frame, respectively, and bar-shaped stretching members. A film, a sheet or the like is supported on the two opposite side members of the outer frame, and the stretching members are pushed together with portions of the film, the sheet or the like into the gaps contiguous with the opposite side members of the outer frame supporting the film, the sheet or the like to stretch the same. The film stretching structure has a relatively simple construction and is capable of holding the film, the sheet or the like taut without allowing the same to crease or slacken.

摘要： A rear projection or translucent screen consisting of a circular Fresnel lens consisting of a plurality of concentrically circular lens elements and a lenticular lens having a plurality of corrugated parallel convex lens elements. Parallel projections or ridges are formed on the surface opposite to the lens surface of the lenticular lens and masking stripes are formed over the projections or ridges. The side surfaces of the projections or ridges are so defined that they will not intercept the light rays emerging from the corrugated parallel convex lens elements. According to one embodiment of the present invention, the top of each of the projections or ridges is formed with a groove and an ink is filled into the groove. According to another embodiment of the present invention, the position of each projection or ridge is deviated from the boundary between the adjacent corrugated parallel convex lens elements by a distance which is determined by a predetermined relationship.

摘要： A process for the preparation of acrylonitrile by the ammoxidation reaction of propylene, characterized by using an oxide type catalyst which contains, as active ingredients, molybdenum, bismuth, iron and at least one element selected from potassium, rubidium and cesium in specifically limited proportions and which may further contain sodium and/or phosphorus. By the use of such a specific catalyst, the selectivity for the desired acrylonitrile is remarkably improved, and there can be attained high yield of the product. In the process of the present invention, the catalyst can maintain a high activity and a high selectivity for a long time, without undergoing attrition. The catalyst is well prevented from sublimation-escaping of the ingredient molybdenum therefrom.
