摘要： An astable multivibrator, driven by a solar battery or other long-term current supply, pulses an electromagnetic stepping drive for intermittently winding up a coil spring which powers a mechanical clockwork. The spring, connected to its stepping drive via a one-way coupling permitting manual rewinding, has one end secured to a leadscrew and has its other end tied to a nut thereon so that the degree of unwinding is indicated by the axial position of the nut on the lead screw. When the spring has been tightened to a predetermined extent, the nut trips an electric switch or a lever to prevent overwinding by disconnecting the multivibrator, arresting the stepping drive or decoupling that drive from its load.

摘要： A timepiece has a stepping motor for intermittently rotating hands to indicate the time, a solar cell for temporarily generating electric charge and capacitors for storing the generated electric charge to supply an operating voltage. A drive circuit repeatedly applies a combination of first and second consecutive driving pulses having electric powers proportional to the operating voltage to the stepping motor, while a detector detects the operating voltage. A control circuit is connected between the drive circuit and the detector for controlling the detector to effect the operating voltage detection after the application of the first driving pulse and before the application of the following second driving pulse. When decrease of the operating voltage is detected after the application of the first driving pulse, the operating voltage is increased before the application of the following second driving pulse so as to ensure the rotation of the hands.
摘要翻译：钟表具有用于间歇地旋转手指示时间的步进电机，用于暂时产生电荷的太阳能电池和用于存储产生的电荷以提供工作电压的电容器。当检测器检测到工作电压时，驱动电路重复地将具有与工作电压成比例的电功率的第一和第二连续驱动脉冲的组合施加到步进电机。控制电路连接在驱动电路和检测器之间，用于控制检测器在施加第一驱动脉冲之后并在施加随后的第二驱动脉冲之前进行工作电压检测。当在施加第一驱动脉冲之后检测到工作电压的降低时，在施加随后的第二驱动脉冲之前增加工作电压，以确保手的旋转。

摘要： For an electrically wound clock, a worm and worm gear drive, wherein the worm is a space-wound helical wire spring, frictionally fitted on a motor shaft, extending beyond the end of the shaft, and unsupported at its outboard end. Engagement with the worm gear takes place at a point beyond the end of the shaft.
