  • Ink jet array
    Patent number: 4389658
    Abstract: A pulsed liquid droplet ejecting apparatus array wherein rectangular piezoelectric transducers are arranged abaxially over ink-containing chambers. An edge of each transducer is fixed against a reaction block so that on excitation of the transducers, the transducers extend into the ink chamber ejecting a droplet.
