摘要： An inexpensive projection lens unit in a rear projection type image display system, having a short focal distance (wide angle of viewing field), high focus and high contrast, and as well, including a power lens made of a glass material having a high refractive index in a range from 1.63 to 1.70 and an Abbe's number of not less than 50 with an optimized incident and emergent configuration in order to satisfactorily correct aberration with a enhanced focusing performance even with a shortened focal distance. Further, the power lens having a high refractive index can exhibit a high power, and accordingly, can carry out satisfactory aberration correction by optimizing the aspheric degree of a plastic lens even though the length of back focus is increased for enhancing the contrast.

摘要： For a projection lens apparatus having a six-group structure that enlarges and projects an image displayed on a projection tube, an appropriate distance is maintained between a power lens and an aspherical lens group that is located near a power lens on the image generation source side, and physical interference with the power lens is eliminated, so that productivity is increased while a cost reduction is achieved. A meniscus lens that has a concave face directed toward a screen and has a refracting power is employed as an aberration correction lens (fourth group lens 4) that is located near the power lens (third group lens 3) on the image generation source side. Further, the lens surface of the meniscus lens on the screen side has an aspherical shape, so that a curvature is increased from the light axis to a predetermined point located between the light axis and the outer edge, and is reduced from the predetermined point to the outer edge. Furthermore, an inexpensive low refractive index material that has an Abbe number (νd) of 57 or higher and a refractive index (nd) of 1.500 or lower and that has superior flowability is employed as the base material for the fourth group lens that is located nearest the glass power lens on the image generation source side.
摘要翻译：对于具有六组结构的投影透镜装置，其放大并投影显示在投影管上的图像，在功率透镜和位于图像生成源侧的功率透镜附近的非球面透镜组之间保持适当的距离并且消除了与功率透镜的物理干扰，从而在实现成本降低的同时提高了生产率。使用具有朝向屏幕的凹面并具有折射光焦度的弯月形透镜作为位于图像产生源侧的功率透镜（第三组透镜3）附近的像差校正透镜（第四组透镜4）。此外，屏幕侧的弯月透镜的透镜表面具有非球面形状，使得曲率从光轴增加到位于光轴和外边缘之间的预定点，并且从预定点减小到外边缘。此外，使用阿贝数（nud）为57以上且折射率（nd）为1.500以下且具有优异的流动性的便宜的低折射率材料作为位于第四组透镜的基材最靠近图像生成源侧的玻璃功率透镜。

摘要： There is provided a package structure for packing a flat display unit which improves workability in taking a flat display unit out of a packing box. A lower cushioning material which supports a display portion of the flat display unit from below has a manual insertion portion so that the display portion can be held at a portion close to a lifting person's body when the display portion is taken out of a lower part of the packing box. A reinforcing rib is provided on a front side of the lower cushioning material to prevent damage to the lower cushioning material due to a reduction in strength. To prevent the lower cushioning material from being taken out together with the display portion when the display portion is taken out, a recess is provided in the lower cushioning material so that the recess is caught on a bending portion in the lower part when the display portion is taken out.
