    • An apparatus for controlling an operating stroke of a reciprocating member to be reciprocated by a drive motor. The apparatus includes an encoder adapted to generate pulses each of which corresponds to a predetermined incremental distance of movement of the reciprocating member, a counter for counting the pulses during movement of the reciprocating member in a forward direction, a device for converting the operating stroke into the number of the pulses corresponding to a multiple of the incremental distance of movement, and a residual distance which is a difference between the operating stroke and the multiple, a device for converting the residual distance into a corresponding residual time, and a device for commanding the drive motor to stop an operation thereof causing a further forward movement of the reciprocating member, when the residual time has elapsed after a count of the counter is equal to the above-indicated number of the pulses.
    • 一种用于控制由驱动马达往复运动的往复运动件的运行行程的装置。 该装置包括编码器,其适于产生脉冲,每个脉冲对应于往复运动部件的预定的增加运动距离,用于在往复运动部件沿向前方向运动期间计数脉冲的计数器,用于将运转行程转换成 对应于增量移动距离的倍数的脉冲数,以及作为操作行程与倍数之间的差的剩余距离,将剩余距离转换为相应的剩余时间的装置,以及用于命令的装置 当计数器的计数等于上述数量的脉冲之后剩余时间已经过去时,驱动马达停止其运动,从而进一步向前运动往复运动件。

    • A self-adjusting motor positioning system comprises a motor including a shaft extending therefrom, a disc coupled to the motor shaft and having at least first and second notches, rotating apparatus coupled to the motor shaft whereby the rotating apparatus is intermittently driven by the motor, a sensor adjacent the disc for detecting the first and second notches, and a control processor coupled to the sensor and the motor for receiving detection signals from the sensor and for turning the motor on and off. The control processor includes memory for storing a time delay count representing a time delay for the control processor to turn off the motor after the second notch is detected by the sensor. The rotating apparatus includes a starting position from which the rotating apparatus begins. The first notch in the disc corresponds to the starting position of the rotating apparatus. The control processor turns the motor off when the time delay expires after the sensor detects the second notch. The sensor senses for the first notch as the motor coasts to a stop, and the control processor adjusts the time delay count if the first notch is not detected when the disc is at a complete stop.
    • 一种自调整电动机定位系统包括一个电动机,包括一个从其延伸的轴,一个联接到电动机轴的盘,具有至少第一和第二槽口,与电动机轴连接的旋转装置,由此旋转装置被电动机间歇地驱动, 邻近所述盘的传感器,用于检测所述第一和第二凹口;以及控制处理器,其耦合到所述传感器和所述电动机,用于接收来自所述传感器的检测信号并且用于接通和关闭所述马达。 控制处理器包括用于存储表示在由传感器检测到第二陷波之后控制处理器关闭电动机的时间延迟的时间延迟计数的存储器。 旋转装置包括开始旋转装置的起始位置。 盘中的第一切口对应于旋转装置的起始位置。 当传感器检测到第二个凹口后,时间延迟到期后,控制处理器关闭电机。 当电机惯性停止时,传感器感测到第一个凹口,而当光盘处于完全停止状态时,如果没有检测到第一个凹槽,则控制处理器调整时间延迟计数。
