Abstract

Official abstract text for this publication.

A liquid jet head is provided with an actuator substrate partitioned by elongated walls of a piezoelectric body and having elongated ejection grooves and elongated non-ejection grooves alternately arrayed thereon so as to penetrate the actuator substrate from an upper surface through a lower surface thereof; a cover plate provided on the upper surface and having first slits communicating with the ejection grooves on one side and second slits communicating with the ejection grooves on the other side; and a nozzle plate provided on the lower surface and having nozzles communicating with the ejection grooves. The non-ejection grooves extend, on the other side, up to a second-side peripheral end of the actuator substrate, and the actuator substrate is left to form raised bottom portions on bottoms of the non-ejection grooves near the second-side peripheral end.

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid jet head comprising: an actuator substrate partitioned by elongated walls of a piezoelectric body, the actuator substrate having elongated ejection grooves and elongated non-ejection grooves separated from one another by the walls and alternately arrayed on the actuator substrate so as to penetrate the actuator substrate from an upper surface through a lower surface thereof, wherein the non-ejection grooves extend from the vicinity of a first-side…
