摘要： PURPOSE:To enhance the responsiveness of an automatic voltage regulator of an AC generator by charging or discharging an auxiliary capacitor at every half wave of the output voltage, and controlling the phase of a field current when the voltage during discharging reaches the set value. CONSTITUTION:An auxiliary capacitor 26 is charged by the output of a variable resistor 22 in case of the negative half voltage of the output voltage V0 of a generator, and discharged through a variable resistor 42 at the positive half wave time. Since the charging voltage Va of the capacitor 26 is low at the starting time, the main capacitor 34 starts charging in the positive half cycle, the charging voltage immediately reaches the breakover voltage of a unidirectional switch 44 to fire a thyristor 16. Since the charging voltage Va becomes high at the normal operation time, a transistor 40 becomes ON. Thus, after the transistor 40 becomes OFF in the positive half cycle, the main capacitor 34 starts charging to control the firing phase of the thyristor 16.
摘要翻译：目的：通过在输出电压的每半个波形下对辅助电容器进行充电或放电来提高交流发电机的自动调压器的响应性，并且在放电期间的电压达到设定值时控制励磁电流的相位。构成：在发电机的输出电压V0的负半电压的情况下，辅助电容器26由可变电阻器22的输出充电，并且通过可变电阻器42在正半波时间放电。由于电容器26的充电电压Va在启动时低，所以主电容器34在正半周期内开始充电，充电电压立即达到单向开关44的跳变电压，以触发晶闸管16.由于充电电压Va在正常工作时变高，晶体管40变为导通。因此，在正半周期中晶体管40截止之后，主电容器34开始充电以控制晶闸管16的点火相位。

摘要： PURPOSE:To efficiently cut off a pipe even if hardness of its material changes without causing damage of a rotary tooth edge, by detecting the load of a cutting motor from its electric current so as to adjust the speed of a feed motor in accordance with a change of the load. CONSTITUTION:A motor, consisting of a series-wound commutator motor, and a reduction gear (both motor and gear not shown in the drawing) are housed in a base bed 10, rotating a chuck 14 to be driven. A cutter 20, die 22 and a burr remover 24 are mounted to a sliding bed 18. A rotary edge 26, which revolves on its own axis, and a series-wound commutator motor 28 driving this rotary edge are provided in the cutter 20. When a pipe is made of hard material, the rotary edge is controlled in a good revolution, simultaneously a feed of the pipe is also controlled at a low speed.

摘要： PURPOSE:To improve work efficiency, by enabling a feed motor, for use of cutting off a pipe, to be used also for its threading work so as to enable the pipe to be both cut off and threaded by a single device. CONSTITUTION:A chuck 14 is rotated and driven by a motor consisting of a series-wound commutator motor. A rotary edge 26 revolving on its own axis and a cutting motor 28, which drives this rotary edge 26 at a high speed through gears, are provided in a cutter 20. The motor 28 is a series-wound commutator motor. When a pipe 34 is threaded after it is cut off, the pipe 34 is turned at a low speed and threaded by pressing a die 22 to an end part of the pipe and driving said feed motor not shown in the drawing.
