摘要： An Inkjet nozzle includes an aperture with a noncircular opening substantially defined by a polynomial equation. A droplet generator is also described which includes a firing chamber fluidically coupled to a fluid reservoir a heating resistor and a nozzle. The nozzle includes an aperture forming a passage from the firing chamber to the exterior of the droplet generator through a top hat layer. The nozzle is defined by a closed polynomial and has a mathematically smooth and mathematically continuous shape around aperture's perimeter wall, with two protrusions extending into the center of the aperture.

摘要： In an embodiment, a fluid ejection device includes a die substrate having first and second fluid slots along opposite substrate sides and separated by a substrate central region. First and second internal columns of closed chambers are associated with the first and second slots, respectively, and the internal columns are separated by the central region. Fluidic channels extending across the central region fluidically couple closed chambers from the first internal column with closed chambers from the second internal column. Pump actuators in each closed chamber pump fluid through the channels from slot to slot.

摘要： An ink jet printhead including a thermo-pneumatic actuator array for ejecting ink from an array of nozzles. The actuator array may include the use of a silicon-on-insulator (SOI) semiconductor wafer including a device layer, a handle layer, and a dielectric layer that physically separates the device layer from the handle layer to simplify printhead formation. During an exemplary process, the SOI wafer is attached to a heater wafer and a nozzle plate is attached to the dielectric layer such that, during use of the printhead, the device layer functions as an actuator membrane. Deflection of the device layer during use of the printhead creates a pressure within an ink chamber which causes ejection of ink from one of the nozzles of the array of nozzles.
