    • An auger-type ice making machine includes a refrigerating cylinder 5, an auger 6 disposed rotatably within the refrigerating cylinder 5 and provided with a spiral blade 6a, a driving motor 8 for driving rotatively the auger 6 and an electric heater mounted around an outlet end portion of the refrigerating cylinder into and through which ice is transported under the effect of rotation of the auger. A coolant vaporizing tube is wound around outer periphery of the refrigerating cylinder, and raw water is fed into the refrigerating cylinder via a feed water pipe. When jamming of ice takes place within the refrigerating cylinder 5, an overcurrent flows through the driving motor 8. The overcurrent is detected by a protector 23 incorporated in a control circuit 30, whereupon the electric heater 22 is electrically energized.
    • 螺旋式制冰机包括制冷缸5,可旋转地设置在冷藏筒5内并具有螺旋叶片6a的螺旋推运器6,用于驱动螺旋推运器6的驱动马达8和安装在出口端周围的电加热器 在螺旋钻旋转的作用下,冰箱的一部分进入并通过冰块输送。 冷却剂蒸发管缠绕在冷藏筒的外周,原水通过给水管送入冷藏筒。 当在冷藏筒5内发生冰块堵塞时,过电流流过驱动电动机8.过电流由装在控制电路30中的保护器23检测,于是电加热器22通电。

    • In a phase locked loop frequency synthesizer having multiple feedback loops, a reference phase signal is developed into two signals having a frequency twice as high as the reference frequency and the phase difference of the two signals is a half wavelength. The output frequency produced by a voltage-controlled oscillator is divided by two frequency dividers in accordance with predetermined frequency division factors. Each of the frequency-divided signals and each of the developed signals are subjected to phase comparison in pairs. A voltage signal corresponding to the phase differences is fed through a low-pass filter and supplied to the voltage-controlled oscillator.
    • 在具有多个反馈回路的锁相环频率合成器中,将参考相位信号产生为具有两倍于参考频率的频率的两个信号,并且两个信号的相位差是半波长。 由压控振荡器产生的输出频率根据预定的分频因子被两个分频器分压。 每个分频信号和每个显影信号成对进行相位比较。 对应于相位差的电压信号通过低通滤波器馈送并提供给压控振荡器。
