    • A powdered medicine multi-dose administering device has a medicine container unit (5b) for containing a unit-dose of medicine under the lower surface of the medicine storage chamber (5a) storing the medicine in a multi-dose amount. A medicine guiding unit (2) moves between a filling position and an administering position while maintaining a contact with the bottom surface. At the filling position, the medicine container unit is opened to the medicine storage chamber and is filled with the medicine. As the medicine container unit moves from the filling position to the administering position, the powdered medicine in the medicine container unit is swept and metered. At the administering position, the medicine in the medicine container unit is injected by the action of the pump unit (3) through a filter (6) and a pipe (2g, 2d, 2c).
    • 粉末药物多剂量给药装置具有药剂容纳单元(5b),用于在药物储存室(5a)的下表面容纳多剂量的药剂,以多剂量存储药物。 药物引导单元(2)在保持与底面的接触的同时在填充位置和给药位置之间移动。 在填充位置,药剂容器单元向药剂储存室开口并填充药剂。 当药剂容器单元从填充位置移动到给药位置时,将药剂容器单元中的粉末药片扫过并计量。 在给药位置,药剂容器单元中的药物通过泵单元(3)的作用通过过滤器(6)和管(2g,2d,2c)注入。

    • In a phase-locked loop circuit, a vertical synchronous separation circuit separates a vertical sync signal from a composite synchronizing signal to detect part of a vertical synchronizing period. A mask circuit masks the composite synchronizing signal during a predetermined period. A selector selects a reference signal or the composite synchronizing signal in accordance with the detection output from the vertical synchronous separation circuit. A phase comparator detects a phase difference between the output from the selector and the reference signal. A voltage-controlled oscillator changes an oscillation frequency upon receiving the output from the phase comparator through a low-pass filter. A counter counts the oscillation output from the voltage-controlled oscillator. A decoder circuit decodes the output from the counter to generate the reference signal, supplies it to the selector and the phase comparator, and resets the counter at a predetermined period. A mask pulse decoder generates a mask pulse to control a mask period of the mask circuit. The composite synchronizing signal is replaced with the reference signal in accordance with the detection output from the vertical synchronous separation circuit and supplied to an input of the phase comparator.
    • 在锁相环电路中,垂直同步分离电路将垂直同步信号与复合同步信号分离,以检测垂直同步周期的一部分。 掩模电路在预定时段期间掩蔽复合同步信号。 选择器根据来自垂直同步分离电路的检测输出来选择参考信号或复合同步信号。 相位比较器检测来自选择器的输出和参考信号之间的相位差。 压控振荡器通过低通滤波器从相位比较器接收到输出时改变振荡频率。 计数器对来自压控振荡器的振荡输出进行计数。 解码器电路对来自计数器的输出进行解码以产生参考信号,将其提供给选择器和相位比较器,并以预定周期复位计数器。 掩模脉冲解码器产生掩模脉冲以控制掩模电路的屏蔽周期。 根据来自垂直同步分离电路的检测输出,将复合同步信号替换为参考信号,并提供给相位比较器的输入端。
