FIELD: process engineering.SUBSTANCE: proposed device comprises multiple address lines and line to transmit starting signal. Besides, it comprises multiple nozzle circuits connected with starting circuit and multiple address lines. Every circuit of nozzle is configured in switching on to eject fluid via different multiple nozzles in response to starting signal. Subset of multiple address lines is connected to every pair of multiple nozzle circuits. Every subset connected to one pair of nozzle circuits is selected so that simultaneous activation of every address line in said subset switches on every nozzle circuit in pair or pairs of nozzle circuits connected with that triad of address lines and no one of other nozzle circuits on multiple nozzle circuits.EFFECT: ejection of different-size drops depending upon activation type.15 cl, 15 dwg |
