CONSTANT SPEED DRIVE UNITS FOR DRIVING DEVICES

摘要

The present invention relates a constant speed device for driving means using a transistor switching effect adapted to an apparatus to obtain an uniform rate of rotation or amplitude for electric motors and electromechanical oscillators which can be sufficiently used for timepieces and instruments, and in which a relatively moving member driven by electrical means is provided, and a control member connected to the junction of a diode and a condenser.
