摘要： A continuous inkjet printer in which a continuous ink stream is deflected at the printhead nozzle bore without the need for charged deflection plates or tunnels. The printhead includes a primary ink delivery channel which delivers a primary flow of pressurized ink through an ink staging chamber to the nozzle bore to create an undeflected ink stream from the printhead. A secondary ink delivery channel adjacent to the primary channel is controlled by a thermally actuated valve to selectively create a lateral flow of pressurized ink into the primary flow thereby causing the emitted ink stream to deflect in a direction opposite to the direction from which the secondary ink stream impinges the primary ink stream in the ink staging chamber. A method of fabricating the printhead includes layering of the thermally actuated valve over the secondary ink delivery channel formed in a silicon substrate and creating the ink staging chamber over the delivery channels with sacrificial material which is later removed through the nozzle bore etched into the chamber wall formed over the sacrificial material.

摘要： A continuous color ink jet print head (40) for an electronic printing device is composed of a nozzle (42), pressurized ink sources (46, 48), and a print head surface (50) having channels (61, 62, 64, 66) disposed therein such that each channel (61, 62, 64, 66) is in communication with the nozzle (42). The continuous color ink jet print head (40) also includes a microvalve (52, 56) disposed within each of the channels (61, 62, 64, 66) such that each channel (61, 62, 64, 66) is connected through the microvalve (52, 56) to a pressurized ink source (46, 48), thereby permitting ink from the pressurized ink source (46, 48) to flow through the channel (61, 62, 64, 66) and thereafter be ejected from the nozzle (42) when the pressurized ink source (46, 48) has attained a particular threshold pressure. The microvalve (52, 56) itself is a thermally activated microvalve (52, 56) that permits colored patterns of dots of varying intensities to be ejected from the nozzle (42) onto a receiver at a constant rate, thereby maintaining a static ink printed pixel size. By selectively controlling the length of time the microvalve (52, 56) is actuated, a range of colored inks is permitted to be ejected from the nozzle (42) onto the receiver.

摘要： A thermal actuator is taught for a micro-electromechanical device. The thermal actuator includes a base element, a cantilevered element extending from the base element and normally residing in a first position. The cantilevered element includes a first layer constructed of a dielectric material having a low thermal coefficient of expansion and a second layer attached to the first layer, the second layer comprising intermetallic titanium aluminide. A pair of electrodes are connected to the second layer to allow an electrical current to be passed through the second layer to thereby cause the temperature of the second layer to rise, the cantilevered element deflecting to a second position as a result of the temperature rise of the second layer and returning to the first position when the electrical current through the second layer is ceased and the temperature thereof decreases. The thermal actuator has particular application in an inkjet device wherein a series of such inkjet devices form an inkjet printhead.

摘要： A method of continuously ejecting liquid includes providing a liquid ejection system that includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member that extends over at least a portion of the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. The compliant membrane includes an orifice. Liquid is provided under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate by a liquid supply. A drop of liquid is caused to break off from the liquid jet by selectively actuating the MEMS transducing member which causes a portion of the compliant membrane to be displaced relative to the liquid chamber.

摘要： A continuous liquid ejection system includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member. A first portion of the MEMS transducing member is anchored to the substrate. A second portion of the MEMS transducing member extends over at least a portion of the liquid chamber and is free to move relative to the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member and a second portion of the compliant membrane is anchored to the substrate. The compliant membrane includes an orifice. A liquid supply provides a liquid to the liquid chamber under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate. The MEMS transducing member is selectively actuated to cause a portion of the compliant membrane to be displaced relative to the liquid chamber to cause a drop of liquid to break off from the liquid jet.
