    • In an automatic exposure control apparatus, image-capturing is performed at a double exposure time TI (I=1, 2, . . . ) and a single exposure time; a CCD output therein produced is applied with a CCD drive signal to perform an integrating operation for a signal in an AE area by using an integration circuit, and then outputs integration values 2EI+SI and EI′+SI′ to an exposure operation/control circuit; and the exposure operation/control circuit then performs an AE operation to receive 2EI+SI−(EI′+SI′)≈EI and compares the value to a target value for determining exposure conditions, and upon receipt of a shutter trigger, it uses an AE operation value containing almost no smear component to determine an appropriate exposure condition even in actual image-recording. According to the apparatus herein stated, exposure errors resulting from smears can be prevented.
    • 在自动曝光控制装置中,以双曝光时间TI(I = 1,2,...)和单次曝光时间执行图像拍摄; 通过使用积分电路对其中产生的CCD输出施加CCD驱动信号,以对AE区域中的信号执行积分运算,然后将积分值2EI + SI和EI'+ SI'输出到曝光操作/控制 电路 并且曝光操作/控制电路然后执行AE操作以接收2EI + SI-(EI'+ SI')≈EI,并将该值与用于确定曝光条件的目标值进行比较,并且在接收到快门触发时,其使用 即使在实际的图像记录中也几乎不包含拖尾分量的AE操作值来确定适当的曝光条件。 根据本文所述的装置,可以防止由涂片引起的曝光误差。

    • A plurality of boring cutters and honing stones are coaxially arranged on a machining head. A bar member is reciprocatingly inserted and splined within a rotary hollow spindle. Both the end opening surface of the spindle and the end of the bar member are taper-engaged with each other so that the bar member may be disengaged and moved forwardly with respect to the spindle. The machining head is coupled with the end surface of the bar member. When the spindle is taper-engaged with the bar member, a workpiece is bored. When the bar member is moved forwardly to release the taper engagement, the workpiece is honed by reciprocating the bar member and the machining head. Thus, the honing operation can be performed with a rigid structure, and both boring and honing operations can be effected by the same machining head.
