摘要： An ink jet head is provided which includes: a piezoelectric board having a plurality of elongated channels arranged parallel to each other and isolated from each other by channel walls; and a nozzle plate having a plurality of nozzle holes provided in association with the respective channels, and bonded onto the piezoelectric board with the nozzle holes located at generally longitudinally middle positions of the respective channels; wherein the nozzle plate has trench-like recesses each having a predetermined width and a predetermined depth and extending perpendicularly to the channels as being spaced equidistantly from the nozzle holes longitudinally of the channels; gaps for communication between adjacent channels are defined by the recesses between a surface of the nozzle plate and upper face portions of the channel walls located equidistantly from the nozzle holes; and active areas contributable to ink ejection are defined in each of the channels on opposite sides of the corresponding nozzle hole along the channel. This arrangement prevents deterioration of ejection characteristics attributable to bonding offset of the nozzle plate, and suppresses residual vibration occurring due to pressure waves without complication of the construction of the ink jet head, thereby ensuring stable ejection characteristics even in high speed driving.
摘要翻译：提供了一种喷墨头，其包括：压电板，其具有彼此平行布置并通过通道壁彼此隔离的多个细长通道; 以及喷嘴板，其具有与各个通道相关联地设置的多个喷嘴孔，并且与各个通道的大致纵向中间位置处的喷嘴孔接合到压电板上; 其中所述喷嘴板具有各自具有预定宽度和预定深度并且与所述通道垂直延伸的沟槽状凹部，其与所述通道的纵向方向上的喷嘴孔等距离地间隔开; 相邻通道之间的连通间隙由喷嘴板的表面与等距离喷嘴孔的通道壁的上表面部分之间的凹槽限定; 并且在沿着通道的相应喷嘴孔的相对侧上的每个通道中限定了有助于喷墨的有效区域。这样可以防止由于喷嘴板的粘合偏移引起的喷射特性的劣化，并且抑制由于压力波而产生的残余振动，而不会使喷墨头的结构复杂化，从而即使在高速驱动中也能确保稳定的喷射特性。

摘要： The step of forming an electrode for external connection applies a conductive resin (10) to one end portion of each of a plurality of ink chambers (26) within each of the ink chambers (26) and to the top surface of each of a plurality of protrusions over a piezoelectric substrate (60) in one line perpendicular to the direction in which the ink chambers (26) extend. Subsequently, the conductive resin (10) located on the top surface of each of the plurality of ink chamber partitions is removed by polishing or grinding. As a result, the conductive resin (10) filling a space within each ink chamber (26) constitutes an electrode for external connection. This allows the capacitance due to the piezoelectric substrate to be decreased. Further, the driving frequency of the ink jet head can be increased. Thus, an ink jet head and its manufacturing method can be provided with a reduced power consumption, with an increased productivity and reliability and that allows a high speed printing.
