Title: Ink flying recording method and device therefor
Inventor: SEKIYA TAKURO
IPC: B41J2/05
Filed: 1990-09-21
Abstract: PURPOSE:To improve picture quality including gradation recording by a method wherein heat gradient in response to input energy is generated at an energy applying section, and a bubble which is generated in response to this heat gradient, and the size of which changes, is made to generate in an ink to send the ink flying from the ink liquid surface. CONSTITUTION:A silicone wafer as a substrate 16 is made into a regenerative layer 23 by heat oxidation, and a heating element layer 24 and electrodes 25 26 are formed, and at the same time, a heating section is formed by exposing the heating element layer 24 into a square shape. Then, under a condition in which driving pulse is small, a rather small bubble 30 under a separated condition is generated, corresponding only with a part which is not covered by a radiating structural body 32, and ink flies by a small ink pole 31, therefore, by a small ink drop. When the driving pulse becomes larger, the size and region of the generated bubble 30 expand, and the ink flies as a rather larger ink drop. When the driving pulse becomes even larger, second coalescence takes place in the generated bubble 30, an it is generated on the whole of the heating section, and the ink flies as a large ink drop.
