Изобретение от юс11тс к области приборостроени .Invention from US to instrument making.
Известные устройства дл измерени скорости движени магнитного носител , содержащие двухщелевую магнитную головку записивоспроизведени , соответствующие усилители, формирователи импульсов, пиковые детекторы , блок регистрации, обладают недостаточной точностью измерени .The prior art devices for measuring the speed of movement of a magnetic carrier, comprising a double-slot magnetic reproducing head, corresponding amplifiers, pulse shapers, peak detectors, a recording unit, have insufficient measurement accuracy.
Дл повыщени точности измерени в предлагаемом устройстве выход усилител воспроизведени через блок синхронизации подключен к входу блокинг-генератора, выход которого через усилитель записи соединен с частотомером и головкой записи.In order to increase the measurement accuracy in the proposed device, the output of the playback amplifier is connected via a synchronization unit to the input of the blocking oscillator, the output of which is connected to the frequency meter and the recording head through the recording amplifier.
На чертеже изображена блок-схема описываемого устройства, состо щего из магнитной головки 1 воспроизведени , усилител 2 воспроизведени , выход которого через блок синхронизации 3 подключен к блокииг-генератору 4. Выход последнего через усилитель записи 5 соединен с частотомером 6 и головкой запи: си 7.The drawing shows a block diagram of the described device, consisting of a magnetic playback head 1, a playback amplifier 2, the output of which is connected via a synchronization unit 3 to a blocking oscillator 4. The output of the latter is connected to a frequency meter 6 and a recording head via a recording amplifier 5: sy 7 .
Устройство работает следующим образом.The device works as follows.
Магнитна головка 7 записывает на магнитный носитель 8 имлульс, выданный блокинггенератором 4 и усиленный усилителем. При движении ленты чмагни тный отпечаток импульса на носителе 8, пройд рассто ние / между головками 7 и 1, воспроизводитс магнитной головкой 1. Усиленный воспроизведенный импульс поступает в блок синхронизацииMagnetic head 7 records on magnetic carrier 8 an impulse issued by a blocking generator 4 and amplified by an amplifier. When the tape moves, the magnetic imprint of the impulse on the carrier 8, the distance traveled / between the heads 7 and 1, is reproduced by the magnetic head 1. The amplified reproduced impulse enters the synchronization unit
3, запускает блокинг-генератор 4, и происходит запись следующего импульса. Импульсы пишутс на носитель с точными интервалами, равными рассто нию I между щел ми магнитных головок. Частотомер 6 показывает частоту следовани импульсов, а посколько они записаны через одинаковые рассто ни , то частота их воспроизведени пр мо пропорциональна скорости движени носител , и он может быть отградуирован в единицах скорости .3, starts the blocking generator 4, and the next pulse is recorded. The pulses are written on the carrier with exact intervals equal to the distance I between the gaps of the magnetic heads. Frequency meter 6 shows the pulse frequency, and since they are recorded at equal distances, the frequency of their reproduction is directly proportional to the speed of movement of the carrier, and it can be calibrated in units of speed.
