The thermoelasticity ink jet actuator which possesses conduction of heat route

摘要

The thermal ink jet assembly in order to use in the ink jet printer assembly in order to achieve the specified negative pressure profile where formation of the liquid drop is promoted, has the conduction of heat expedient which is formed. Regarding desirable execution form, conduction of heat expedient passive bending layer of non thermal conductivity (56) is arranged in, the layer where the material whose such as aluminum thermal conductivity is very high is thin (54) it has. When producing to control by controlling the nearness to conduction of heat layer from the heater of the actuator it is possible the speed where entire cooling rate of the actuator and therefore passive bending layer return to stationary position.
