Description

Known ferrite transistor cells made on two series-connected triodes, a storage transformer and an input transformer. The main disadvantage of such devices is that the power of the impulse to write off the unit must exceed the power of the impulse to write to the unit. In addition, the well-known cells have insufficient speed.

In the described cell, to increase the speed and reduce the power of the impulse to write off the unit, the field winding of the memory transformer is connected between the emitter of the key triode and the base of the main triode.

The circuit diagram of the cell is shown in the drawing.

The recording of the unit is carried out on the winding / memory transformer 2. The inhibit pulses enter winding 3 of the same transformer. At the same time, the signal “wired down writes off a unit from the core of the transformer 2 without issuing a signal to the load. At the time of the prohibition signal, triode 4 is not energized, since triode 5 is closed. This allows simultaneous delivery of the prohibiting pulses to the winding 5 and the charging pulses from the terminals 6. Such an operation mode increases the speed of the device. The windings / and 5 can be made the same, since the power consumed for recording a unit by winding / and writing it off for winding 3 with the same switching circuit of triodes 4 to 5 is the same.

The output signals from the cell are removed from the terminals 7 t 8.
