Abstract: A multi-nozzle ink jet head formed through semiconductor processes. The multi-nozzle head has a head substrate in which are formed a plurality of nozzles and a plurality of pressure chambers, a diaphragm that acts as a common electrode and covers the plurality of pressure chambers, piezoelectric body layers that are provided in correspondence with the pressure chambers on the diaphragm, and individual electrode layers that are provided on the piezoelectric body layers and have individual electrode parts corresponding to the pressure chambers and wiring parts for the individual electrode parts. By interposing a low-dielectric-constant layer or an insulating layer in the region of the wiring parts, or not disposing the common electrode in the region of the wiring parts, the electrical capacitance of the driving parts is reduced, and hence a driving lag is prevented from occurring, and moreover unwanted vibration of the piezoelectric bodies is prevented.

Abstract: A multi-nozzle ink jet head having a diaphragm that effectively utilizes the force generated by thin-film piezoelectric elements is disclosed. The head (2) has a head substrate (28) in which are formed a plurality of nozzles (39) and a plurality of pressure chambers (29), a multi-layer diaphragm (23-1, 23-2), piezoelectric elements (27), and individual electrodes (26). By making the thickness of the common electrode layer (23-1) of the multi-layer diaphragm be thin but such that problems do not occur during multi-pin driving, optimization of the rigid layer becomes possible, and hence it is possible to use the force generated by the thin-film piezoelectric elements efficiently in ink ejection.

Abstract: The ink replenishment frequency is increased in an inkjet head having nozzles for injecting ink. Independent dampers are provided in ink supply passages to impart an acoustic capacitance to the ink supply passages, and therefore a reciprocal action is generated between the pressure chambers and the ink supply passages, whereby the operation of ink replenishment can be stimulated. Accordingly, the ink replenishment frequency can be increased by a factor of approximately 3, without having to provide functional elements in the ink supply passage.

Abstract: An ink jet head using bimorph drivers and a manufacturing method thereof are disclosed. The head has pressure chambers 6 that each communicates with a nozzle 9 and stores ink, and bimorph drivers that each has a piezoelectric body 1 and a vibrating plate 2 and that are for applying pressure to the pressure chambers 6; three peripheral sides of each of the bimorph drivers are fixed, and the other side is not fixed. Since one side of the piezoelectric body of each of the bimorph drivers is made to be free, tensile stress can be released without pressure leakage. As a result, the displacement and pressure required for ejecting ink drops can be obtained even if the width of the piezoelectric bodies is narrow. A high-density multi-nozzle head can thus be realized.
