摘要： A screen is hung from a screen frame with hanging members bonded to the upper side of a front sheet. Supporting members are disposed on the lower side of the front sheet and, by mounting a Fresnel lens sheet on the supporting members, a tension is given by its weight to the front sheet in the vertical direction. Further, a tension in the horizontal direction is given to the front sheet. Long holes are so formed in the hanging members that the hanging members on the right and left sides of the screen by expansion or contraction of the screen are made greater in the extent of shifting in the horizontal direction than the hanging member in the central part.

摘要： The present invention provides a technology that makes it possible to display high-quality images by reducing a reflection loss of the image light entering the upper left and right ends of a transmissive screen. At the image generation source side of the Fresnel lens sheet, a totally reflective prism section (10) is provided that totally reflects incident rays of light and causes the light to exit toward the image-watching side. At the image-watching side of the Fresnel lens sheet (6), a refractive prism section (11) is also provided that refracts the light entering from the totally reflective prism section (10) and causes the light to exit toward the image-watching side. The refractive prism section (11) has a roughed refractive face.

摘要： Image disturbance called speckle noise occurs when an image generator has a small effective screen size and a projection lens has a small effective diameter. The present invention is intended to reduce speckle noise. In an optical projector, a viewing angle enlarging ember (60) for enlarging viewing angle or a scattering member (28) for scattering image light is disposed near an image display device (18), such as a liquid crystal panel. Speckle noise can be reduced, suppressing the deterioration of resolution and contrast.

摘要： A total reflecting prism portion is formed on an image generation source side of a Fresnel lens sheet which constitutes a rear projection type screen. The total reflecting prism portion is formed in an area in which the angle of incidence of a projection image projected from an optical part on the Fresnel lens sheet is at least about 40°. The total reflecting prism portion causes incident light to be outputted as output light at a predetermined output angle by a total reflection phenomenon after a first refraction phenomenon. Further, a refracting prism portion is formed on an image monitoring side of the Fresnel lens sheet. The refracting prism portion is formed in an area opposed to the portion where the total reflecting prism portion is not formed. The refracting prism portion causes incident light to be outputted as output light at a predetermined output angle by a second refraction phenomenon.

摘要： The present invention provides a method for producing a Group III nitride compound semiconductor crystal, the semiconductor crystal being grown through the flux method employing a flux. At least a portion of a substrate on which the semiconductor crystal is to be grown is formed of a flux-soluble material. While the semiconductor crystal is grown on a surface of the substrate, the flux-soluble material is dissolved in the flux from a surface of the substrate that is opposite the surface on which the semiconductor crystal is grown. Alternatively, after the semiconductor crystal has been grown on a surface of the substrate, the flux-soluble material is dissolved in the flux from a surface of the substrate that is opposite the surface on which the semiconductor crystal has been grown. The flux-soluble material is formed of silicon. Alternatively, the flux-soluble material or the substrate is formed of a Group III nitride compound semiconductor having a dislocation density higher than that of the semiconductor crystal to be grown.
