Abstract
An improved ink jet print head structure. The print head includes a cylindrical glass rod having a bore extending along the axis of the rod. A surface is ground on the rod parallel to and near the bore. A metal organic paste is fired on the surface and a piezoelectric driver plate is soldered to the paste. A silicon nozzle plate is bonded to the front of the rod by means of an anodic bonding technique. The head structure may be attached to a charging electrode by means of an insulating support member, resulting in a prealigned and easily replaceable unit. Several alternative embodiments of the head structure and means for attaching the structure to an input line are disclosed.
