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： An apparatus for 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 bending portion extending from the base element and a free end portion residing in a first position. The thermo-mechanical bending portion has a base end width, wb, adjacent the base element and a free end width, wf, adjacent the free end portion wherein the base end width is substantially greater than the free end width. The thermal actuator further comprises apparatus adapted to apply a heat pulse directly to the thermo-mechanical bending portion causing the deflection of the free end portion of the cantilevered element to a second position. The width of the thermo-mechanical bending portion may reduce substantially monotonically as a function of the distance away from the base element or in at least one step reduction. The apparatus adapted to apply a heat pulse may comprise a thin film resistor. Alternatively, the thermo-mechanical bending portion may comprise a layer of electrically resistive material having a heater resistor formed therein to which is applied an electrical pulse to cause rapid deflection of the free end portion and ejection of a liquid 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.
