  • Drop-on-demand print head using gasket fan-in
    Patent number: 4771298
    Abstract: An ink jet drop-on-demand print head comprises a plurality of electromechanical transducers, and ink from a manifold is conveyed to the transducers. The fluid path between the transducers and the corresponding nozzle in the nozzle array comprises a resilient dual function means. The dual function means not only provides the fan-in section but also seals the fluid path in fluid tight relation without the use of any adhesive or bonding material.

  • Aspirator for an ink jet printer
    Patent number: 4375062
    Abstract: Disclosed is the design for an aspirator (10) of a continuous stream ink jet printer. With reference to FIG. 1, the aspirator includes a tunnel configuration (20) wherein the tunnel cross-sectional area diverges from the inlet (23) to the outlet (22), the axial area gradient being inversely proportional to the intended velocity of air through the tunnel (20) so that the cross-sectional area of the outlet (22) is greater than the cross-sectional area of the inlet (23). In this manner, air movement through the tunnel (20) is substantially constant.
