    摘要： The present invention provides a liquid discharge head less susceptible to crosstalk between displacement elements adjacent to each other, and a recording device using the liquid discharge head. The liquid discharge head includes a plate-shaped passage member providing a plurality of liquid pressurizing chambers of identical shape which open into a main surface and are arranged in a matrix shape, a plurality of liquid discharge holes, and a plurality of individual supply paths; and a plate-shaped piezoelectric actuator having a common electrode, a piezoelectric layer, and a plurality of individual electrodes laminated on a diaphragm. The plate-shaped passage member and the plate-shaped piezoelectric actuator are laminated one upon another so that the diaphragm and the piezoelectric layer cover the plurality of liquid pressurizing chambers. In a plan view of the liquid discharge head, an opening of each of the liquid pressurizing chambers is a polygonal shape having at least one acute angle shaped corner. A connection electrode led out to outside the liquid pressurizing chamber in the liquid pressurizing chamber and the individual electrode is disposed in a parallelogram shaped region including two sides holding therebetween an acute angle shaped corner of the liquid pressurizing chamber, and two corners adjacent to the corner.

    摘要： A system for ejecting droplets of a fluid is described. The system includes a substrate having a flow path body that includes a fluid pumping chamber, a descender fluidically connected to the fluid pumping chamber, and a nozzle fluidically connected to the descender. The nozzle is arranged to eject droplets of fluid through an outlet formed in an outer substrate surface. The flow path body also includes a recirculation passage fluidically connected to the descender. The system for ejecting droplets of a fluid also includes a fluid supply tank fluidically connected to the fluid pumping chamber, a fluid return tank fluidically connected to the recirculation passage, and a pump fluidically connecting the fluid return tank and the fluid supply tank. In some implementations, a flow of fluid through the flow path body is at a flow rate sufficient to force air bubbles or contaminants through the flow path body.

    摘要： A fluid ejector includes a fluid ejection module and an integrated circuit element. The fluid ejection module includes a substrate having a plurality of fluid paths, a plurality of actuators, and a plurality of conductive traces, each actuator configured to cause a fluid to be ejected from a nozzle of an associated fluid path. The integrated circuit element is mounted on the fluid ejection module and is electrically connected with the conductive traces of the fluid ejection module such that an electrical connection of the module enables a signal sent to the fluid ejection module to be transmitted to the integrated circuit element, processed on the integrated circuit element, and output to the fluid ejection module to drive the actuator.
