Micromachine, liquid jet recording head using such micromachine, and liquid jet recording apparatus having such liquid jet recording head mounted thereon

摘要

A micromachine comprises at least one heat generating unit arranged on the surface of a substrate, means for retaining liquid having a liquid retaining portion along the heat generating unit, a rotator rotatively supported in the liquid retaining portion of means for retaining liquid. This rotator is structured to rotate by means of the boiling of liquid in the liquid retaining portion by heat generated by the heat generating unit. The micromachine, such a micropump or a micromotor, is incorporated in a liquid jet recording head to cause recording liquid to flow compulsorily in order to remove accumulated bubbles in the liquid paths for the maintenance of good performance of the liquid jet recording head at all times. <IMAGE>
