摘要： A printer includes a printhead and a source of fluid. The printhead includes a nozzle. The fluid is under pressure sufficient to eject a column of the fluid through the nozzle. The fluid has a temperature. An asymmetric thermal modulator is associated with the nozzle and includes a structure that transiently lowers the temperature of a first portion of the fluid as the fluid is ejected through the nozzle and a structure that transiently raises the temperature of a second portion of the fluid as the fluid is ejected through the nozzle.

摘要： A drop-on-demand liquid emission device, such as for example an ink jet printer, includes a member movable through a path for driving liquid from the device, wherein the speed at which the member moves is reduced over the time period that liquid is being expelled. During that time period, a portion of the liquid flows through a passage away from the nozzle orifice. According to a feature of the present invention, a variable flow restrictor increases the resistance to flow through the passage during the time period that liquid is being expelled; thereby tending to compensate for the reduction of the liquid-expulsion force over the time period. The result is a reduction of undesirable satellite droplets following a main drop.

摘要： A printer includes a printhead and a source of liquid. The printhead includes a nozzle bore. The liquid is under pressure sufficient to eject a column of the liquid through the nozzle bore. The liquid has a temperature. A thermal modulator is associated with the nozzle bore. The thermal modulator is operable to transiently lower the temperature of the liquid as the liquid is ejected through the nozzle bore. An electrical pulse source is in electrical communication with the thermal modulator. The electrical pulse source is operable to provide a series of pulses to the thermal modulator that control the transient temperature lowering of the liquid. The series of pulses includes a first pulse applied at a first power level for transferring heat to the liquid, a second pulse applied at a second power level for transferring heat to the liquid, and a third pulse applied at a third power level for transferring heat to the liquid. The third power level is in between the first power level and the second power level.

摘要： A liquid emission device includes a chamber having a nozzle orifice. Separately addressable dual electrodes are positioned on opposite sides of a central electrode. The three electrodes are aligned with the nozzle orifice. A rigid electrically insulating coupler connects the two addressable electrodes. To eject a drop, an electrostatic charge is applied to the addressable electrode nearest to the nozzle orifice, which pulls that electrode away from the orifice, drawing liquid into the expanding chamber. The other addressable electrode moves in conjunction, storing potential energy in the system. Subsequently the addressable electrode nearest to the nozzle is de-energized and the other addressable electrode is energized, causing the other electrode to be pulled toward the central electrode in conjunction with the release of the stored elastic potential energy. This action pressurizes the liquid in the chamber behind the nozzle orifice, causing a drop to be ejected from the nozzle orifice.

摘要： A liquid emission device includes a chamber having a nozzle orifice. Separately addressable dual electrodes are positioned on opposite sides of a ground electrode. The three electrodes are aligned with the nozzle orifice. A rigid electrically insulating coupler connects the two addressable electrodes. To eject a drop, an electrostatic charge is applied to the addressable electrode nearest to the nozzle orifice, which pulls that electrode away from the orifice, drawing liquid into the expanding chamber. The other addressable electrode moves in conjunction, storing potential energy in the system. Subsequently the addressable electrode nearest to the nozzle is de-energized and the other addressable electrode is energized, causing the other electrode to be pulled toward the ground electrode in conjunction with the release of the stored elastic potential energy. This action pressurizes the liquid in the chamber behind the nozzle orifice, causing a drop to be ejected from the nozzle orifice.
