Abstract

Методът и съоръжението са приложими в оптиката и електронната промишленост. Методът се състои в това, че се оценява величината на изтегляне, която съответства на дължината на изтегления кристал, и се изработва импулсна поредица, пропорционална на оцененото движение. С този импулсен ред се управлява блок за програмно управление, в който предварително се задават факторите, определящи формата на кристала. Изработеният по този начин и съответстващ на теоретичната форма на кристала сигнал се сравнява с постоянния сигнал за измерване на тегло, а с диференциалния сигнал се регулира температурата на стопилката. Устройството се състои от разположен в камерата за получаване на кристали тигел, обхванат от нагревателен елемент и съдържащ стопилка, регулатори на обороти, изтеглящ и въртящ двигател, преобразувател, разположен между кристалната ос и осите на изтеглящия и въртящия двигател и регулиран чрез мощен регулатор генератор на мощност. Кристал,разположен в камерата за получаване на кристали, навлиза в стопилката и е свързан чрез кристалната ос с механичния преобразувател. Устройството включва една електронна везна, диференциален сигнален генератор и усилвател и разположени успоредно на оста на изтеглящия двигател дистанционен датчик на импулси, блок за програмно управление и измервателен блок. Измервателния блок се състои от първи и втори брояч и синхронизиращ блок, чийто свързани помежду си входове образуват входа на измервателния блок. Включени са и блок за стартиране на измерването, датчик за време и цифров компаратор. 5 претенции, 5 фигуриThe method and apparatus are applicable in the optics and electronics industries. The method consists in estimating the amount of pull, which corresponds to the length of the pulled crystal, and producing a pulse train proportional to the estimated movement. With this pulse train, a program control block is controlled, in which the factors determining the shape of the crystal are preset. The signal produced in this way and corresponding to the theoretical shape of the crystal is compared with the constant signal for weight measurement, and the temperature of the melt is adjusted with the differential signal. The device consists of a crucible located in the chamber for receiving crystals, covered by a heating element and containing a melt, speed regulators, a pulling and rotating motor, a converter located between the crystal axis and the axes of the pulling and rotating motors and regulated by a powerful regulator generator of power. A crystal placed in the crystal receiving chamber enters the melt and is connected via the crystal axis to the mechanical transducer. The device includes an electronic balance, a differential signal generator and an amplifier, and a remote pulse sensor, a program control unit and a measuring unit located parallel to the axis of the pulling motor. The measuring block consists of a first and second counter and a synchronizing block whose interconnected inputs form the input of the measuring block. Also included is a measurement starter unit, a timer, and a digital comparator. 5 claims, 5 figures
