    • An elongated remotely controlled pan and tilt television camera, ideally suitable for inspecting pipeline interiors, is able to be constructed with extremely small transverse dimensions due to compact packaging of control mechanisms disposed in the camera front end inside an optical dome. An outer gimbal is rotatable (i.e., panned) relative to the camera front end and is in the form of a frame within which an inner gimbal is mounted to be rotatable (i.e., tilted) relative to the outer gimbal. A lens, a lens focus control motor and a tilt motor are all mounted on the inner gimbal so as to be movable therewith. The pan motor is positionally fixed in the camera housing and rotates the outer gimbal by means of a drive cable and pulley secured to the outer gimbal. A CCD detector is located remotely from its associated electronics circuitry on a CCD circuit board secured to the inner gimbal so that the detector is movable with the lens and receives an optical image therefrom. The electrical signals representing the image and produced by the detector are processed into appropriate video format by circuitry disposed in fixed position within the camera housing. The lens is an automatic iris lens having its iris control circuitry located remotely from the lens so that a small lens structure may be employed. The CCD board serves as a tie point for all wiring between gimbal-mounted components and positionally fixed components disposed in the camera housing.
    • 由于安装在光学圆顶罩内的摄像机前端的控制机构的紧凑包装,能够构造出非常小的横向尺寸的,非常适合于检查管道内部的细长的远程控制的平移和倾斜电视摄像机。 外万向架相对于照相机前端可旋转(即平移),并且是框架的形式,内框架相对于外万向架可安装成可旋转(即倾斜)。 透镜,透镜聚焦控制电机和倾斜电动机都安装在内万向架上,以便与其一起移动。 平移电机位置固定在摄像机外壳中,并通过固定在外部万向架上的驱动电缆和滑轮使外部万向节旋转。 CCD检测器远离其相关联的电子电路位于固定到内万向架的CCD电路板上,使得检测器可与透镜一起移动并从其接收光学图像。 表示图像并由检测器产生的电信号通过设置在相机壳体内的固定位置的电路​​被处理成适当的视频格式。 透镜是一种自动光圈透镜,其光圈控制电路远离镜头,从而可以采用小透镜结构。 CCD板用作万向节安装部件和位于相机外壳中的位置固定部件之间的所有接线的连接点。

    • A mail slot data cartridge exchange system for a data storage system may comprise a drawer mounted to the data storage system so that the drawer can be moved between a retracted position and an extended position. A cartridge magazine for holding at least one data cartridge is sized to be removably received by the drawer so that at least a portion of the cartridge magazine is exposed when the drawer is in the extended position. A drawer stop index member is operatively associated with the drawer so that the movement of the drawer stop index member corresponds to movement of the drawer. A lock apparatus mounted to the data storage system is switchable between a locked state and an unlocked state. The lock apparatus engages the drawer stop index member when the lock apparatus is in the locked state and when the drawer is in a regulated extended position.
    • 用于数据存储系统的邮槽插槽数据盒更换系统可以包括安装到数据存储系统的抽屉,使得抽屉能够在缩回位置和延伸位置之间移动。 用于保持至少一个数据盒的盒式存储器的尺寸被设计成由抽屉可移除地容纳,使得当抽屉处于伸出位置时,盒式存储盒的至少一部分被露出。 抽屉停止分度构件与抽屉可操作地相关联,使得抽屉止动构件的运动对应于抽屉的移动。 安装到数据存储系统的锁定装置可在锁定状态和解锁状态之间切换。 当锁定装置处于锁定状态时和当抽屉处于限制的伸出位置时,锁定装置接合抽屉停止索引构件。
