    摘要: An ink jet printhead chip includes a wafer substrate. Drive circuitry is positioned on the wafer substrate. A plurality of nozzle arrangements is positioned on the wafer substrate. Each nozzle arrangement includes nozzle chamber walls and a roof wall positioned on the wafer substrate to define a nozzle chamber and an ink ejection port in the roof wall. A micro-electromechanical actuator is connected to the drive circuitry. The actuator includes a movable member that is displaceable on receipt of a signal from the drive circuitry. The movable member defines a displacement surface that acts on ink in the nozzle chamber to eject the ink from the ink ejection port. An area of the displacement surface is between half and twice a cross sectional area of the ink ejection port.

    摘要: A liquid-firing head includes a nozzle firing a liquid drop; a liquid chamber communicating with the nozzle; a vibration plate which acts as a wall of the liquid chamber; and an electrode facing the vibration plate. The vibration plate is deformed by an electrostatic force, and, thereby, the liquid drop is fired through the nozzle. A groove for forming a gap between the electrode and the vibration plate is formed in the electrode.

The method of fabricating a flextensional transducer capable of ejecting a flowable material includes ultrasonically metal welding an actuator body having an outer diameter and an aperture to a transducer membrane having an outer diameter and an aperture. The transducer membrane is also ultrasonically metal welded to a gland or nozzle capable of housing a portion of the flowable material. The gland or nozzle includes a surface adjacent to the transducer membrane having an aperture. The outer diameter of the actuator body is smaller than the aperture of the gland or nozzle.

    摘要: A combined deflection electrode and phase sensor electrode for a deflection type ink jet printer is made up of a ceramic support plate 19, a conductive layer 21 acting as the deflection electrode, layers of insulator 25 covering the conductive layer 21, and a patch of conductive material on the layers of insulator 25 to provide a phase sensor electrode 29 (Alternative constructions are also disclosed). A time of flight sensor electrode 31 may also be provided in the same way. The layers of insulator 25 prevent the sensor electrodes 29, 31 from being electrically connected, by splashes of conductive ink, to the deflection electrode provided by the conductive layer 21. The sensor electrodes 29,31 can have a larger sensing area than separately provided electrodes, allowing them to be further from the ink jet and thereby easing alignment requirements. Additionally, the flight path of the ink jet from the nozzle 1 to the gutter 11 is shortened by placing the sensor electrodes 29, 31 within the length of the deflection electrode. The combined electrode design may be applied to single jet printers, double jet printers and printers having an array of jets (e.g. for printing graphics).

    摘要: A liquid drop emitter, such as an ink jet device, for emitting a series of liquid drops at high frequency is disclosed. The drop emitter comprises a liquid-filled chamber having a nozzle, a thermo-mechanical actuator for applying pressure to liquid at the nozzle, means for heating the thermo-mechanical actuator in response to electrical pulses, and a controller for determining the parameters of the electrical pulses. The method of operating comprises determining a nominal electrical pulse having a nominal energy E0, a nominal pulse duration TP0, which causes the emission of at least one drop at a sustained period of repetition TC. The method of operating further determines a steady state electrical pulse having energy E0, a steady state pulse duration TPss, which, when applied to the electroresistive means does not cause the emission or weeping of the liquid from the nozzle. The method applies to the means for heating, during every period of time TC, a nominal electrical pulse to emit at least one drop, or a steady state electrical pulse, so that an average power PAVE, where PAVE=E0/TC, is applied to the liquid drop emitter in order to maintain a steady state thermal condition.

    摘要: A micro electro-magnetic system includes a substrate. An actuator mechanism is arranged on the substrate. An actuator arm is displaceably mounted on the substrate and is displaceable with respect to the substrate along a predetermined path of travel. The actuator arm has a plurality of spaced magnetic poles along its length. An electromagnetic field generator is operatively positioned with respect to the actuator arm and is capable of producing an electromagnetic field of sufficient strength to interact with the spaced magnetic poles so that the actuator arm is displaced along the path of travel. A control system is provided for controlling operation of the electromagnetic field generator.
