摘要： To provide a projector that hardly causes deterioration of an image resulted from stray light. A neutral density filter, of which posture can be fine-adjusted by a posture regulating mechanism, is placed in a space between a second dichroic mirror and a liquid crystal light valve. Thus, it is possible to remove stray light, corresponding to condensed light resulted from multi-pass through a field lens or the like, to the outside of a light path by merely tilting the neutral density filter adequately. It is thus possible to project an image having homogeneous brightness (illuminance at the white level) across the entire screen, which in turn makes it possible to project an image having no irregularities in color across the entire screen.
摘要翻译：提供几乎不引起由杂散光引起的图像劣化的投影仪。可以通过姿势调节机构将姿势微调的中性密度滤光器放置在第二分色镜与液晶光阀之间的空间中。因此，通过适当地倾斜中性浓度滤光器，可以将对应于多次通过场透镜等的聚光的杂散光移除到光路的外部。因此，可以在整个屏幕上投射具有均匀亮度（在白色水平的照度）的图像，这进而使得可以在整个屏幕上投射没有颜色不均匀的图像。

摘要： A mechanical hand amusement device consisting of a movable grip member joined by a rod, which extends through a tubular arm, to a hand member having a fixed thumb and four finger members which bend inward when the grip member is squeezed. Each finger member includes three hollow segments which are joined by flexible hinges at the tops, and have a flexible strap which is anchored within the fingertip segment running along the bottoms. The strap extending through each of the finger members is coupled to the rod so that a portion of the strap is retracted into the hand member when the grip member is squeezed. The resulting forces move the finger members inward in a grasping motion. A spring within the hand member returns the elements to their at-rest positions when the grip member is released.
