数は設計上任意に設定できる。In FIG. 2, reference numeral 7 denotes a rotary power source having a built-in spring as in FIG. Reference numeral 8 denotes a speed-up gear train corresponding to 2. 9 is a gear having magnetic poles. In the configuration, 10 is a donut-shaped permanent magnet, which is magnetized in the vertical direction of the circular surface. Each surface is in contact with 11 and 12 high permeability gears. 11 and 12 have the same shape, and each tooth faces each other. 13 is a solenoid coil inserted between 11 and 12. Reference numeral 14 denotes a control circuit to which both ends of the solenoid coil are connected. The present invention is a mechanism for regulating the rotational power composed of 9 to 12 through 13 solenoid coils in 14 circuits.
The rotation of 9 is performed with a torque increased from 7. In this case, since magnets are used, it is necessary that the layouts 7 and 8 are made of a material having a small magnetic susceptibility and magnetic permeability, including the peripheral configuration, and that the layout of the gears 9 to 12 has a small magnetic influence. FIG. 3 shows an example of 14 control circuits, and 17 is a crystal oscillator serving as a cycle standard. Reference numeral 18 denotes a frequency divider that divides a high-frequency crystal oscillation signal into an appropriate cycle. 20 is half each
This is the connection of the frequency divider. Reference numeral 15 denotes both terminals of the solenoid coil shown in FIG. 16 is a frequency divider. 19 is the same as 20
This is the connection of the 1/1 frequency divider. Reference numeral 21 denotes a connection of a logic signal comparison circuit shown in detail in FIG. 22 is an electronic switch. This turns on and off according to the level of the final logic signal of the 21 comparison circuits. 23 and 24 are resistors, respectively. The function of this circuit is to convert 18 output standard period signals and 16 output signals to 19,
This is a circuit that controls the accumulated cycles of the 20 frequency dividers to be equal. In short, when the period of 16 is cumulatively shorter than the period of 18, the switch of 22 is turned on and the resistance at both ends of the solenoid coil is reduced. This increases power heat consumption and slows down. In the opposite case, the switch 22 is turned off, the power consumption is reduced, and the degree of deceleration is reduced. Mainspring torque range, 24, 23
A stable cycle can be obtained by appropriately setting the resistance value of the above and the constant of the generator by the solenoid coil. These constants can be set arbitrarily in design.
