    Abstract: A method of operation of an acoustic droplet emitter with an array of droplet emitting utilizing high liquid flow rates. The higher flow rates prevent excess heat absorption during the droplet emission process and allow for excess heat generated by control electronics to be transferred to the flowing liquid after droplet emission but before it leaves the droplet emitter. This prevents excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.

    Abstract: Various fluidic techniques can employ ducting structures, such as microstructures, that extend between other components, such as plate-like structures. A ducting structure can, for example, include an inlet opening toward or near one plate-like structure, an outlet opening toward or near another plate-like structure, and a duct in which fluid flows after being received through the inlet opening and before being provided through the outlet opening. In some implementations, a ducting structure is photo-defined, such as by exposing a photoimageable structure and then removing either exposed or unexposed regions. In some implementations, a ducting structure is a freestanding polymer microstructure. In some implementations, ducting structures are microstructures that extend approximately the same length between first and second plate-like structures, and have a ratio of length to maximum cavity diameter of approximately two or more. A printhead implementation includes an array of such microstructures supported between drive side and drop side assemblies.

    Abstract: A droplet emitter with an array of droplet emitting devices constructed such that a flowing liquid used create the droplets can flow through the droplet emitter at higher flow rates. The higher flow rates prevent excess heat absorption during the droplet emission process and allow for excess heat generated by control electronics to be transferred to the flowing liquid after droplet emission but before it leaves the droplet emitter. This prevents excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.

    Abstract: A print element for an impact printer comprising a metal alloy insert member having a plurality of beams extending radially outward from a center section having an opening in the center thereof and a plurality of apertures spaced around the center opening and positioned between the center opening and the beams. Molded to the ends of the beams are character slugs having an impact surface engageable by hammer means, a print section having a print surface shaped in the form of a character and a capture section for coupling to the end of a beam whereby the energy imparted to the slug by a print hammer is substantially reflected in stresses in the print section of the slug rather than the capture section. A plastic hub is fixedly coupled to the insert member by a plurality of projections, each of which extends through a respective one of the apertures in the insert member and coacts therewith. The hub includes a flag extending radially outward a distance so as to expose a previously printed character when properly positioned relative thereto.
