Title:
MANUFACTURE OF INK JET HEAD
Document Type and Number:
Japanese Patent JPH081949
Kind Code:
A
Abstract:

PURPOSE: To provide a method for manufacturing of an ink jet head having opposing electrodes capable of raising heating efficiency of a conductive ink, fixing a boiling section of the ink on a substrate, achieving stable ink flow and ink ejection and reducing power consumption.

CONSTITUTION: Signal electrodes 22a, 22b having prescribed shapes are formed such that by forming oxidation thin film layers 30a, 30b are formed on metallic surfaces by applying a processing voltage in a conductive solution.to a metallic material that is processed to the signal electrodes 22a, 22b. Thereby, it is possible to form the electrode of which current density of the surface is uniform in the real using condition and to realize stable ink ejection with effective and stable ink flow. Further, an aspect ratio is enhanced so that the power consumption is reduced.
