    • A compound lathe in which a headstock is horizontally movable along a spindle axis to provide longitudinal feeding of a workpiece mounted for rotation with the spindle and a saddle carrying a turret is vertically movable to provide transverse feeding. The saddle is slidably disposed on vertical guideways which is formed on a column mounted on a bed at the back of the headstock rearwardly of cutting areas of the workpiece and which vertically extends in a plane parallel to the axis of the spindle. The turret supports tools for turning, milling, drilling and other operations. Numerically controlled servo motors preferably position the headstock and saddle. A secondary workpiece gripping means is provided to grip the end of the workpiece opposite the headstock and is releasably connected to the headstock for movement therewith. The gripping means allows accurate secondary machining of the cut-off portion of a parted workpiece by the tools on the turret.
    • 一种复合车床,其中主轴箱可沿着主轴轴线水平移动,以提供安装成与主轴一起旋转的工件的纵向进给,并且具有承载转台的鞍座可垂直移动以提供横向进给。 鞍座可滑动地设置在垂直导轨上,该垂直导轨形成在安装在主轴箱背面的床上的柱上,该床在工件的切割区域的后面,并且在平行于心轴的平面的垂直方向上垂直延伸。 转塔支持车削,铣削,钻孔和其他操作的工具。 数控伺服电机优选地定位头架和鞍座。 第二工件夹持装置被设置成夹紧工件的与主轴箱相对的端部,并且可释放地连接到主轴箱以与其一起运动。 夹持装置允许通过转台上的工具对分割工件的切割部分进行精确的二次加工。

    • An apparatus for driving a display panel having drive lines and capacitive light emitting elements. The apparatus sequentially selects one scanning line from the scanning lines every scanning period of input video data including a gradation level to specify a drive line corresponding to at least one capacitive light emitting element driven to emit light on the one scanning line in accordance with the input video data, generates a driving signal having a pulse width in accordance with the gradation level every scanning period, and applies the one capacitive light emitting element with a voltage equal to or higher than a light emission threshold voltage in a forward direction for a duration in which the driving signal is generated, through the one scanning line and the specified drive line, and applies the specified drive line with a predetermined potential in response to elimination of the driving signal to decrease the voltage applied to the one capacitive light emitting element in the forward direction to a voltage lower than the light emission threshold voltage.
    • 一种用于驱动具有驱动线和电容发光元件的显示面板的装置。 该装置依次从扫描行中选择一条扫描行,每个扫描行包括灰度等级的输入视频数据的每个扫描周期,以指定与至少一个电容发光元件相对应的驱动线,该电容发光元件根据输入被驱动以在一条扫描线上发光 视频数据产生具有根据每个扫描周期的灰度级别的脉冲宽度的驱动信号,并将具有等于或高于发光阈值电压的电容式发光元件在正向上施加一段持续时间 通过一条扫描线和指定的驱动线产生驱动信号,并且响应于消除驱动信号而施加具有预定电位的指定驱动线,以降低施加到该驱动信号中的一个电容发光元件的电压 向前方向到低于发光阈值电压的电压。
