摘要： The coarse/fine adjustment coaxial handle for feeding microscope stage comprises a feed screw shaft, a tubular member rotatably fitted over the feed screw shaft and equipped with a disc plate fixed thereto, a fine adjustment handle rotatably fitted over the tubular member and surrounding the disc plate, a reduction gear mechanism interposed between the feed screw shaft and the fine adjustment knob, a first frictional resistance imparting mechanism for imparting frictional resistance to the tubular member, second frictional resistance imparting mechanism for imparting frictional resistance to the disc plate, and a coarse adjustment handle pivoted to an eccentric position on another disc plate connected to the disc plate. The coarse/fine adjustment coaxial handle permits very fine stage feeding without fail and coarse adjustment smoothly with simple operations.

摘要： A hard endoscope of oblique view type which provides equal illumination of the range of visibility of the objective optical system. The endoscope has an exterior tubular member with an interior housing member disposed eccentrically within the tubular member and carrying an inspection optical system, with the distal end of the endoscope terminating in an oblique planar surface. Illuminating means are carried between the housing member and the exterior tubular member. In the region of the oblique planar surface, the interior of the tubular member and the exterior of the housing member define a passage for the illuminating means having a generally crescent-shap, or, preferably, two cylindrical surfaces in which the illuminating means are carried to transmit light from the oblique planar surface that will transmit light to produce the image of the illumated object, so that it may be clearly seen by the inspection optical system.
摘要翻译：一种倾斜式硬内窥镜，其提供物镜光学系统的可见度范围的相等照明。所述内窥镜具有外部管状构件，所述外部管状构件具有偏心地设置在所述管状构件内并且承载检查光学系统的内部壳体构件，所述内窥镜的远端终止于倾斜的平坦表面。照明装置承载在外壳构件和外部管状构件之间。在倾斜的平坦表面的区域中，管状构件的内部和壳体构件的外部限定了用于照明装置的通道，该通道具有大致新月形或优选地在其中携带照明装置的两个圆柱形表面以透射来自倾斜的平坦表面的光，其将透射光以产生被照射物体的图像，使得可以通过检查光学系统清楚地看到。
