    • An apparatus for corneal surgery to correct a refractive error by ablating corneal tissue with a laser beam emitted from a laser source and delivered onto a cornea of a patient's eye with a light delivering optical system, the apparatus comprising an irradiation area limiting device for limiting an irradiation area of the laser beam and for varying the irradiation area, a first control device for controlling the irradiation area limiting device so as to reduce an ablation amount as the laser beam irradiates further away from a flattest meridian of astigmatism whereby effecting astigmatic correction, a second control device for controlling the irradiation area limiting device so as to increase an ablation amount as the laser beam irradiates further away from a steepest meridian of astigmatism whereby effecting astigmatic correction, and an arithmetic device for dividing a refractive power required for astigmatic correction into halves approximately-equally so that an approximately half of the astigmatic correction is achieved by the first control device and the residual astigmatic correction is achieved by the second control device.

    • An opto-video inspection system for inspecting and examining miniaturized solid-state devices, such as hybrids. An XY table simultaneously positions a known good device and a device to be inspected under respective stereo-zoom microscopes. A TV camera is coupled to each microscope. The XY table, under microprocessor control, is manipulated to select the "target" or wire bond to be viewed. The selected sites may be simultaneously viewed upon a split screen video display or, alternatively, either the known good device or the device being inspected may be separately viewed through the associated stereo-zoom microscope or on the video screen. Dwell time at each site is computer selectable, as is the sequencing of sites to be viewed. Defective bonds, imperfections or other conditions are permanently recorded through a printer which automatically associates the code printed thereby with the site in view at that time. An operator keyboard permits completed program steps to be recalled for review or for reprogramming, if desired. The known good device may be replaced by either a video tape or video disc containing a record of each site to be examined or, alternatively, a strip of photographic film, each site being selected by the microprocessor in accordance with the site of the device under inspection presently being examined.
    • 一种用于检查和检查小型化固态设备(如混合动力)的光视频检测系统。 XY表同时定位在相应的立体变焦显微镜下检查的已知的良好装置和装置。 电视摄像机连接到每个显微镜。 在微处理器控制下的XY表被操纵以选择要查看的“目标”或引线键。 可以在分屏显示器上同时观看所选择的位置,或者可以通过相关的立体变焦显微镜或视频屏幕分别观察已知的良好设备或被检查的设备。 每个站点的停留时间是计算机可选择的,以及要查看的站点的排序。 通过打印机永久记录不良的粘合,缺陷或其他条件,打印机将自动将由此打印的代码与当时的视野相关联。 如果需要,操作员键盘允许完成的程序步骤被调回以进行审查或重新编程。 已知的良好设备可以由包含要检查的每个站点的记录的录像带或视频盘替代,或者替代地,照相胶片条,每个位置由微处理器根据设备的位置选择 检查目前正在审查中。
