СПОСОБ АВТОМАТИЧЕСКОЙ КОМПЕНСАЦИИ ИЗМЕНЕНИЯ КРУТИЗНЫ РАДИОЛАМП ВО ВРЕМЕНИMETHOD OF AUTOMATIC COMPENSATION OF CHANGING THE TIGHTNESS OF A RADIOLAMP IN TIME

За влено 12 окт бр  1961 г. за № 747830/26-9It was filed on Oct. 12, 1961, No. 747830 / 26-9.

в Комитет по делам изобретений и открытий при Совете Министров СССР Опубликовано в «Бюллетене изобретений № 23 за 1962 г.to the Committee on Inventions and Discoveries at the Council of Ministers of the USSR Published in «Bulletin of inventions No. 23 for 1962

Основной причиной изменени  усилительных свойств крутизны радиоламп во времени  вл етс  изменение эмиссионных свойств их катодов (старение).The main reason for the change in the amplification properties of the steepness of the radio tubes over time is the change in the emission properties of their cathodes (aging).

Известен способ автоматической компенсации изменени  крутизны радиоламп во времени, который требует наличи  отдельного высоковольтного источника компенсирующего напр жени , повышенного анодного напр жени  и большой посто нной времени катодной цепиA known method for automatically compensating for the change in the steepness of the radio tubes over time, which requires a separate high-voltage source of compensating voltage, increased anodic voltage, and a large time constant of the cathode circuit.

Часто невозможно повысить анодное напр жение и значительно увеличивать посто нную времени катодной цепи, так как быстрые изменени  напр жени  питани  или сигнала вызывают относительно медленные изменени  режима работы лампы и всей схемы.It is often impossible to increase the anode voltage and significantly increase the time constant of the cathode circuit, since rapid changes in the supply voltage or signal voltage cause relatively slow changes in the lamp mode and the whole circuit.

Предлагаемый способ позвол ет получить компенсацию без применени  высокостабильного источника компенсирующего напр жени  повышенного анодного напр жени  и исключаетс  необходимость иметь большую посто нную времени катодной цепи. Дл  этого компенсирующее напр жение создают с помощью нелинейного делител  с вспомогательным диодом, включенного в цепь источника анодного напр жени The proposed method makes it possible to obtain compensation without the use of a highly stable source of compensating voltage of increased anodic voltage and eliminates the need to have a longer time constant of the cathode circuit. For this, the compensating voltage is created using a nonlinear divider with an auxiliary diode connected to the circuit of the anode voltage source.

На чертеже изображена схема осуществлени  предлагаемого спосооз .The drawing shows the scheme of the proposed method.

в схеме компенсирующее напр жение формируетс  при помощи включени  в катодную цепь сопротивлени  / и применени  делител  напр жени , одним элементом которого  вл етс  вспомогательный диод, работающий от общего с радиолампой 2 катода 3 Компенсирующее напр жение поступает с делител  на управл ющую сетку 4 лампы . Посто нна  времени цепи сопротивлени  / и конденсатора 5 резко ГНИЖЯРТГЯ и (J..C.in the circuit, a compensating voltage is formed by including a resistor / and a voltage divider in the cathode circuit, one element of which is an auxiliary diode operating from a common cathode 3 with the radio tube 2. The constant time of the resistance circuit / and the capacitor 5 is abruptly GNYRTGYA and (J..C.
