    • There is disclosed a scanning electron charged-particle beam instrument in which the image does not escape during rotation even if the center of mechanical rotation is not coincident with the center of the image. The instrument is so operated that the center position of the image is fixed when a mechanical rotation is made if the center of mechanical rotation is not coincident with the center of the image. For this purpose, when the specimen stage assembly is rotated mechanically, the X-stage of the specimen stage assembly is driven to move in the X-direction. The Y-stage of the stage assembly is driven to move in the Y-direction. The distance L between the center of mechanical rotation and the moving speed of the X-Y stage are interlinked. The apparent speed of the rotational speed of the image on the viewing screen is made constant irrespective of the distance L. In practice, the moving speed of the X-Y stage is increased with increasing the distance L.
    • 公开了一种扫描电子带电粒子束仪器,其中即使机械旋转的中心与图像的中心不一致,图像在旋转期间也不会逸出。 如果机械旋转的中心与图像的中心不一致,则在进行机械旋转时,该仪器的操作使得图像的中心位置是固定的。 为此,当样品台组件机械旋转时,样品台组件的X级被驱动以沿X方向移动。 舞台组件的Y档被驱动沿Y方向移动。 机械旋转中心与X-Y平台的移动速度之间的距离L是相互连接的。 观看屏幕上的图像的转速的视在速度与距离L无关。实际上,X-Y平台的移动速度随着距离L的增加而增加。

    • A mother tape is adapted to perform magnetic or thermal high-speed contact printing for duplicating video data or information to be reproduced in a VTR monitor with eliminating spike noise otherwise contained in the reproduced control signal. The mother tape stores video information including control signals. The control signals have a waveform which has a first level immediately following the leading edge and lower than a second level corresponding to the normal high level, and a third level immediately following the trailing edge and higher than a fourth constant level corresponding to the normal low level. The first- and third-level waveform "buffers" thus created tend to suppress the spike noise conventionally occurring at the leading and trailing edges of the reproduced control signal and ensure more reliable tracking, tape speed control and so forth.
    • 母带适于执行磁性或热的高速接触印刷,以在VTR监视器中复制要再现的视频数据或信息,同时消除另外包含在再现的控制信号中的尖峰噪声。 母带存储包括控制信号的视频信息。 控制信号具有一个波形,其具有紧跟在前沿之后的第一电平并且低于对应于正常高电平的第二电平,以及紧跟在后沿之后的第三电平并且高于对应于正常低电平的第四恒定电平 水平。 由此产生的第一级和第三级波形“缓冲器”倾向于抑制通常在再现的控制信号的前沿和后沿发生的尖峰噪声,并确保更可靠的跟踪,磁带速度控制等。
