DEFLECTION DEVICE FOR CATHODE-RAY INDICATOR Russian patent published in 2005 - IPC

FIELD: engineering of devices for controlling indicator devices.

SUBSTANCE: device has subtracter circuit, amplifier, deflecting coil, check communication resistor and check communication circuit. Device additionally has two-side key, capacitor, diode, second amplifier, second check communication circuit and transistor key. Decrease of consumed power occurs because for the most part of time of generation of reversed drive of scanning first amplifier is disengaged from deflecting coil, and for changing of current flow direction resonance effect in inductive-capacity contour is implemented.

EFFECT: decreased power, consumed during generation of reversed scanning drive in bitmap rows generation mode.
