摘要： 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 in a rigid casing so that on excitation of the transducers, the transducers extend into the ink chamber ejecting a droplet. The array is made by first producing completed individual jets and then assembling the completed jets into an array. The jets are designed to reduce mechanical crosstalk and to efficiently utilize the drive pulse.

摘要： 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 by electrical pulses, the transducers extend into the ink chamber ejecting a drop. An improved method for rigidly mounting the piezoelectric transducers to the reaction block for improved efficiency is disclosed. Further, the design includes an improved mechanical crosstalk reducing member comprising a rigid member containing a void.

摘要： 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. The ink chamber is formed in a relatively rigid material to increase the efficiency of utilization of the drive pulse.
