    摘要： An improved pinch valve includes a camshaft and associated cam(s) controlling the position of a pivotally-mounted first pinch arm and an opposed, pivotally-mounted second pinch arm. The respective pinch arms are provided symmetrically about a central plane which contains an axis of the camshaft. A spring extends across the central plane and interconnects the respective pinch arms so as to urge both pinch arms towards the central plane. A mechanical advantage lever is provided such that the pinching force is greater than the spring force.

    摘要： An ink supply system for an inkjet printhead. The ink supply system includes: an ink reservoir for containing ink, the ink reservoir having a flexible wall; a spring contained within the ink reservoir, the spring being configured for biasing the flexible wall away from an opposite wall of the ink reservoir; an ink conduit providing fluid communication between the ink reservoir and the printhead; and a pressure device for positively pressurizing the flexible wall of the ink reservoir against the bias of the spring. The pressure device includes an air pump for positively pressurizing an air chamber communicating with the flexible wall, such that actuation of the air pump causes the wall to move towards the opposite wall against the bias of the spring.

    摘要： A method of minimizing ink consumption during printhead priming in an inkjet printer. The printhead has a nozzle face defining an array of nozzles for ejecting ink on to a media substrate. The method includes the steps of: providing a porous pad having a contact face dimensioned so that it can encompass all the nozzles in the array; moving the porous pad such that the contact face engages the nozzle face to cover the array of nozzles; forcing ink into the printhead under pressure until ink flows out the nozzles in the array and into the porous pad engaged with the nozzle face; and withdrawing the porous pad such that the contact face disengages the nozzle face.

    摘要： An inkjet printhead that has an array of ink chambers arranged to remove air bubbles entrained in the ink supply flow. Each of the ink chambers has a nozzle and a thermal actuator respectively, the array of ink chambers defined by sidewalls extending between a nozzle plate and an underlying wafer substrate. The printhead also has ink inlets extending through the underlying wafer substrate. Each of the ink inlets has an ink permeable trap and a vent sized such that the surface tension of an ink meniscus across the vent prevents ink leakage. The ink permeable trap has columns extending from the underlying wafer substrate to the vent to direct gas bubbles entrained in a flow of ink through the ink inlet towards the vent.

    摘要： A printing nozzle arrangement is provided having an electrical current source, a fluid chamber having a fluid inlet and fluid ejection port, a heating element within the chamber electrically connected to the electrical current source, and a microprocessor. The heating element is configured such that electrical current applied by the electrical current source at a predetermined energy level causes resistive heating and ejection of the fluid from the fluid ejection port. The microprocessor is configured to test for faulty operation of the heating element by causing application of electrical current for a predetermined duration which does not result in fluid ejection. When faulty operation is determined, the microprocessor is configured to cause application of electrical current at an energy level significantly greater than the predetermined energy level in an attempt to clear fluid blockages associated with the chamber.

    摘要： A method of depositing encapsulant on a line of wire bonds to a die is described, the die having a back surface in contact with the support structure and an active surface opposing the back surface, the active surface having electrical contact pads and functional elements spaced from the contact pads. The method involves the steps of providing a die mounted to the support structure, positioning a barrier between the contact pads and the functional elements, the barrier being proximate to, but spaced from the active surface, depositing a bead of encapsulant onto the electrical contact pads while the barrier remains stationary such that the barrier prevents the encapsulant from contacting the functional elements, removing the barrier when the bead of encapsulant has been deposited. The fluidic resistance generated by the gap between the barrier and the active surface means that the amount of encapsulant that flows into the gap and onto the active surface is almost constant. The reduced flow variations make the encapsulant front closely correspond to the shape of the barrier. Greater control of the encapsulant front allows the functional elements of the active surface of the die to be closer to the contact pads.
