    • An arrangement for varying the triggering phase of a thyristor or other controllable switch employed to vary the excitation of a sweep deflection circuit during changes in the circuit load is described. The output of a winding of the deflection transformer is converted to a constant-amplitude sawtooth voltage which has a DC component proportional to the amplitude of the then-occurring forward sweep portion of the sweep voltage. A zener diode or other comparison element coupled to the output of a variable voltage divider whose input is fed by the resulting sawtooth voltage generates a trigger pulse for the controllable switch at the instant, during each cycle of the sweep waveform, that the constant-amplitude sawtooth voltage exceeds a predetermined value.
    • 描述了用于改变用于在电路负载变化期间改变扫掠偏转电路的激励的晶闸管或其他可控开关的触发相位的装置。 偏转变换器的绕组的输出被转换成恒幅锯齿波电压,其具有与扫描电压的当时发生的正向扫描部分的幅度成比例的直流分量。 耦合到可变分压器的输出的齐纳二极管或其他比较元件,其输入由所产生的锯齿波电压馈送,在扫描波形的每个周期期间在瞬间产生用于可控开关的触发脉冲,即恒定幅度 锯齿波电压超过预定值。

    • A galvano-plastically produced graduation carrier comprising fine perforations located within a perforation zone wherein stability enhancement regions in the form of prominences and depressions in the embodiment are located outside the perforation zone. The stability enhancement regions enhance the ability of the graduation carrier to be self-supporting. The area of the graduation carrier within the perforation zone can therefore be made thinner than other areas of the graduation carrier. This provides a graduation carrier which not only has improved edge sharpness and fineness of the perforations but also a high bending rigidity and improved handleability.
    • 包括位于穿孔区域内的精细穿孔的电流 - 塑性生成的分级载体,其中在该实施例中突起和凹陷形式的稳定性增强区域位于穿孔区域的外侧。 稳定性增强区域增强了毕业载体自支撑的能力。 因此,穿孔区域内的分度载体的面积可以比分度载体的其他区域薄。 这提供了一种渐变载体,其不仅具有改善的边缘锐度和穿孔的细度,而且具有高的弯曲刚度和改善的可操作性。
