Abstract
Abstract Multi-layer ink jet apparatus 10,110 includes a plurality of channels 12,112 comprising chambers including inlets and orifices 14,114 and transducers 22,122 coupled to the chambers 24,124. The various channels 12,112 are located in different layers 16,116 that stagger with respect to a plane transverse to the layers 16,116 so as to achieve a high density array of ink jet orifices 14,114.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
100 words
An ink jet apparatus comprising a plurality of channels, each of said channels including a chamber, an inlet opening to said chamber and an ink drop and ejection orifice, the improvement comprising a plurality of layers, each of said layers performing a different function in more than one channel formed by each said layer, at least one of said plurality of said layers being located between immediately adjacent orifices in different ones of said layers so as to provide a high-density multi-channel array wherein the spacing between immediately adjacent chambers is substantially equal to the spacing between immediately adjacent orifices.
Claim 2
Dependent Claim
100 words
An ink jet apparatus comprising a plurality of channels, each of said channels including a chamber, an inlet opening to said chamber and an ink drop and ejection orifice, the improvement comprising a plurality of layers, each of said layers performing a different function in more than one channel formed by each said layer, at least one of said plurality of said layers being located between immediately adjacent orifices in different ones of said layers so as to provide a high-density multi-channel array wherein the spacing between immediately adjacent chambers is substantially equal to the spacing between immediately adjacent orifices.
Claim 3
Dependent Claim
25 words
