摘要： A simple yet versatile noncontact optical inspection instrument and method are described for the inspection of magnetic disk surfaces for surface defects. This instrument is capable of inspecting the disk surface at any point in the disk manufacturing process. Surface defects such as bumps, pits and scratches can be measured. Surface contaminants such as particles and stains can also be measured. The instrument is also capable of discriminating between surface defects and surface contaminants. The instrument is comprised of two identical optical sensors which are located on opposite sides of the disk. A carriage supports and translates these sensors along the disk radius while a spindle rotates the disk. Both surfaces of the disk are therefore simultaneously scanned in a spiral fashion. The sensor's illumination optics produce a monochromatic focused spot of light which is normally incident upon the disk surface. The sensor uses two collection optics channels which simultaneously detect both the specular reflected light and the diffuse scattered light produced by the disk surface. Both the angle and power of the specular reflected light are measured, while just the power of the diffuse scattered light is measured. The output signals from the sensors are processed to estimate the size of the defects and to determine the type of defect.
摘要翻译：描述了一种简单而通用的非接触式光学检测仪器和方法，用于检查表面缺陷的磁盘表面。该仪器能够在磁盘制造过程的任何时刻检查磁盘表面。可以测量诸如凸块，凹坑和划痕的表面缺陷。还可以测量颗粒和污渍等表面污染物。该仪器还能够区分表面缺陷和表面污染物。仪器由两个相同的光学传感器构成，位于光盘的相对两侧。当主轴旋转磁盘时，滑架沿着磁盘半径支撑并平移这些传感器。因此，盘的两个表面都以螺旋方式同时扫描。传感器的照明光学器件产生通常入射在盘表面上的单色聚光光点。该传感器使用两个收集光学通道，其同时检测镜面反射光和由盘表面产生的漫射散射光。测量镜面反射光的角度和功率，同时测量漫射散射光的功率。来自传感器的输出信号被处理以估计缺陷的尺寸并确定缺陷的类型。

摘要： A frictional door holder and stop is designed to provide users with a device that retains a door in an opened position. It is simply comprised of a door holder, a door stop, and a buffer. The door holder, a bent sheet metal structure, has a door holder top near the middle to contact the door's bottom surface, a door holder front end bent upward to reduce the friction force between the door holder and the floor and prevent the floor from being scratched, and a door holder rear end set underneath the door stop to be held to a fixed position relative to the door stop and floor by connectors. The present invention is used for doors with a little retuning force making the door close such as the doors without a door closer. With the frictional door holder and stop, the door can be easily closed as usual without any extra actions such as releasing a holder by a hand or a foot. Its simple structure and characteristic of combining the door holder with the door stop will benefit the users and manufacturers.
摘要翻译：摩擦门保持器和止动器被设计为向用户提供将门保持在打开位置的装置。它只是由门支架，门挡和缓冲器构成。门支架，弯曲的金属板结构，在中间附近具有门保持器顶部以接触门的底面，向上弯曲的门保持器前端以减小门保持器和地板之间的摩擦力，并防止地板划伤，并且门保持器后端设置在门挡块下方，以通过连接器相对于门挡块和地板保持在固定位置。本发明用于具有稍微重新调整力的门，使门关闭，例如门，而不用靠近门。通过摩擦门支架和挡块，门可以像往常一样轻松关闭，无需任何额外的操作，例如用手或脚释放支架。其结构和门把与门挡结合的结构和特点将有利于用户和制造商。
