摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：在具有用于注入墨水的喷嘴的喷墨头中，墨水补充频率增加。在供墨通道中设置独立的阻尼器，以向油墨供应通道提供声学电容，因此在压力室和供墨通道之间产生相互作用，从而可以刺激墨水补充操作。因此，墨水补充频率可以增加约3倍，而不必在墨水供应通道中提供功能元件。
