INKJET PRINT HEAD, PRINTER SYSTEM, AND METHOD FOR EJECTING DROPLET OF BUBBLE FORMING LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a useful inkjet print head, a printer system, and a method for ejecting a droplet of a bubble forming liquid.;SOLUTION: This inkjet print head comprises a plurality of chambers, each storing a bubble forming liquid, a structural body that is adapted to demarcate the plurality of chambers and has a less thickness than 5 microns, a plurality of nozzles that are built in the structural body such that nozzles are arranged with respect to the chambers in one by one correspondence, and at least one heater element that is provided in each chamber corresponding to each nozzle. Each heater element is provided so as to be in thermal contact with the bubble forming liquid and is adapted to form a bubble in the bubble forming liquid. Each heater element is constituted such that it heats at least a part of the bubble forming liquid so as to eject a droplet of the bubble forming liquid through the respective corresponding nozzle. A pressure in each chamber is roughly one atmospheric pressure.;COPYRIGHT: (C)2009,JPO&INPIT
