    摘要: A continuous ink jet print head is formed using a combination of traditional CMOS technology to form the various controlling electrical circuits on a silicon substrate having insulating layer(s) which provide electrical connections and a MEMS technology for forming nozzle openings. A blocking structure is formed in the insulating layer(s) between a first ink channel formed in the silicon substrate and a second ink channel formed in the insulating layer(s). The blocking structure causes ink to flow around the blocking structure and thereby develop lateral flow components to the liquid entering the second channel so that, for droplets selected for printing, as the stream of droplets emanates from the bore of the nozzle, there is provided a reduced amount of heat needed for operating a heating element adjacent each nozzle opening.

    摘要: An ink jet print head is formed of a silicon substrate that includes an integrated circuit formed therein for controlling operation of the print head. The silicon substrate has one or more ink channels formed therein along the longitudinal direction of the nozzle array. An insulating layer or layers overlie the silicon substrate and has a series or an array of nozzle openings or bores formed therein along the length of the substrate and each nozzle opening communicates with an ink channel. The area comprising the nozzle openings forms a generally planar surface to facilitate maintenance of the printhead. A heater element is associated with each nozzle opening or bore for asymmetrically heating ink as ink passes through the nozzle opening or bore.

    摘要: A printer having mechanically-assisted ink droplet separation and method of using same, for separating an ink meniscus from an ink nozzle orifice while clearing-away particulate matter from about the orifice. In a preferred embodiment of the invention, a heater surrounds an orifice formed by the nozzle, the orifice having an ink meniscus residing therein. As the heater heats the ink meniscus, surface tension of the ink meniscus decreases, thereby causing the ink meniscus to extend outwardly from the orifice to define an extended ink meniscus. A cutter, which is disposed near the orifice, includes a plate member disposed opposite an outside surface of the nozzle so as to define a passage between the outside surface and the plate member. The plate member has an opening aligned with the orifice and in communication with the passage. A gas pressure regulator in communication with the passage supplies pressurized gas into the passage, which gas flows along the passage an through the opening. As the gas flows through the opening, it impinges the extended ink meniscus to separate the extended ink meniscus from the orifice. As the extended ink meniscus separates from the orifice, it forms an ink droplet that travels to a receiver medium, so that an ink spot is placed onto the receiver medium. Moreover, as the gas flows through the opening, the gas clears-away particulate matter from about the orifice.

    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
