    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： An apparatus for and method of operating a thermal actuator for a micromechanical device, especially a liquid drop emitter such as an ink jet printhead, is disclosed. The disclosed thermal actuator comprises a base element and a cantilevered element including a thermo-mechanical bender portion extending from the base element to a free end tip. The thermo-mechanical bender portion includes a barrier layer constructed of a dielectric material having low thermal conductivity, a first deflector layer constructed of a first electrically resistive material having a large coefficient of thermal expansion, and a second deflector layer constructed of a second electrically resistive material having a large coefficient of thermal expansion wherein the barrier layer is bonded between the first and second deflector layers. The thermo-mechanical bender portion further has a base end and base end width, wb, adjacent the base element, and a free end and free end width, wf, adjacent the free end tip, wherein the base end width is substantially greater than the free end width. A first heater resistor is formed in the first deflector layer and adapted to apply heat energy having a first spatial thermal pattern which results in a first deflector layer base end temperature increase, &Dgr;T1b, that is greater than a first deflector layer free end temperature increase, &Dgr;T1f. A second heater resistor is formed in the second deflector layer and adapted to apply heat energy having a second spatial thermal pattern which results in a second deflector layer base end temperature increase, &Dgr;T2b that is greater than a second deflector layer free end temperature increase, &Dgr;T2f. Application of an electrical pulse to either the first or second heater resistors causes deflection of the cantilevered element, followed by restoration of the cantilevered element to an initial position as heat diffuses through the barrier layer and the cantilevered element reaches a uniform temperature. For liquid drop emitter embodiments, the thermal actuator resides in a liquid-filled chamber that includes a nozzle for ejecting liquid. Application of electrical pulses to the heater resistors is used to adjust the characteristics of liquid drop emission. The barrier layer exhibits a heat transfer time constant &tgr;B. The thermal actuator is activated by a heat pulses of duration &tgr;P wherein &tgr;P

    摘要： A drop emission device includes a chamber having a nozzle orifice through which a drop of liquid can be emitted. A deformable electrode is associated with the chamber such that movement of the electrode in a first direction increases the chamber's volume and movement of the electrode in a second direction decreases the chamber's volume to emit a drop through the nozzle orifice. A fixed electrode opposes to the deformable electrode to define a second chamber there between such that control of relative voltage differences between the deformable and the fixed electrodes selectively moves the deformable electrode in the first or second directions. The variable volume is vented to a source of dielectric material through an opening in the fixed electrode. The ratio of the cross-sectional area of the opening to the perimeter of the opening is greater than 0.5 μm, and is preferably about 5 μm.

    摘要： An actuator is made by depositing an electrode layer on an initial layer. A patterned layer of sacrificial material is formed on the first electrode layer such that a region of the first electrode layer is exposed through the subsequent layer. A second electrode layer is deposited and patterned on the subsequent layer. Then, a third patterned layer of sacrificial material is formed on the second electrode layer with an opening there through to the exposed region of the first electrode layer. A structure is deposited, patterned and planarized on the third layer expose a surface of the third layer. A third electrode layer is deposited and patterned on the planarized structure and the exposed surface of the third layer. The sacrificial material is partially removed, whereby the first electrode layer, the structure, and the third electrode layer are free to move together relative to the second electrode layer.
