摘要： A secondary battery operating method for charging and discharging a secondary battery using zinc as the negative electrode active material. After the termination of the normal discharge, direct current supply means is connected to the secondary battery in opposite polarity relation with each other and the secondary battery is reverse charged in a polarity opposite to the normal polarity. As a result of this reversed charge, the zinc remaining on the negative electrode after the termination of the normal discharge is completely dissolved into the electrolyte. If necessary, the energy stored in the secondary battery after the termination of the normal discharge is regenerated during the reversed charge.

摘要： Plural series of digital pattern data are determined by PWMing a sine wave by a triangular wave and further classified into each series by the number of triangles included within a half cycle of the sine wave. An appropriate series of data are selected according to a frequency command. The selected data are further adjusted in response to a voltage control command. On the basis of the selected and adjusted pattern data and in response to a half period signal of triangular wave and triangle slope signals, a PWMed pulse is generated through a logical circuit. In the case where the generator is incorporated with an induction motor driving system, it is possible to control speed (frequency), torque (voltage), rotational directions, and torque fluctuations (phase difference) of an induction motor accurately at high response speed.
摘要翻译：数字图案数据的多个系列通过用三角波PWM正弦波来确定，并且通过包括在正弦波的半周期内的三角形的数量进一步分类为每个系列。根据频率命令选择适当的数据系列。响应于电压控制命令进一步调整所选择的数据。基于选择和调整的图案数据，并且响应于三角波和三角斜度信号的半周期信号，通过逻辑电路产生PWM脉冲。在发电机与感应电动机驱动系统结合的情况下，可以以高响应速度精确地控制感应电动机的速度（频率），转矩（电压），转动方向和转矩波动（相位差）。
