    • In an ink jet head that reduces failure or abnormality in ink ejection, electric charge/discharge is applied between opposed electrodes and diaphragms to eject ink droplets from ink nozzles. Each of the opposed electrodes includes a main electrode and a sub-electrode formed on the nozzle side and in common with sub-electrodes for the other diaphragms. Auxiliary electric charge is applied between the sub-electrode and the diaphragms so that the menisci or ink in the ink nozzles vibrate without ejecting unnecessary ink droplets and to shorten the time for tail portions of ejected ink columns to leave the ink nozzles. Ink in ink channels is diffused so that the ink viscosity does not increase due to evaporation of ink solvent. Also, the menisci in the nozzles are drawn into the ink chambers so that unnecessary ink droplets are not ejected immediately after printing ink droplets are ejected.
    • 在降低墨水喷射的故障或异常的喷墨头中,在相对的电极和隔膜之间施加电荷/放电以从墨水喷嘴喷射墨滴。 每个相对电极包括形成在喷嘴侧上的主电极和副电极,并且与用于其它隔膜的子电极共同。 辅助电荷施加在子电极和隔膜之间,使得墨水喷嘴中的半月板或墨水不会喷出不必要的墨滴并缩短喷射墨水柱尾部离开墨水喷嘴的时间。 油墨通道中的油墨扩散,使得由于油墨溶剂的蒸发而导致油墨粘度不增加。 此外,喷嘴中的半月板被吸入墨室中,使得在喷墨墨滴之后不再喷出不必要的墨滴。

    • An improved ink jet head is provided. This improved ink jet head comprises a diaphragm, which is part of an ink chamber. The diaphragm includes a segment which contacts an opposing wall by a drive voltage lower than that for the rest of the diaphragm. The ink jet head also comprises an opposing wall opposite to the diaphragm. When the pressure for ink droplet ejection is generated, the segment of the diaphragm contacts the opposing wall, creating an extremely low compliance state. After ink droplet ejection, the segment of the diaphragm separates from the opposing wall, producing a high compliance state that absorbs the pressure created in the ink chamber by oscillation in the ink channel. Thus, pressure in the ink chamber resulting from ink vibration in the ink path including the ink chamber is buffered to prevent satellite emissions. When plural different gaps are formed between the diaphragm and the opposing wall to create the segments requires different drive voltage for contacting the opposing wall, the part of the diaphragm contributing to ink droplet ejection can be selected by appropriately controlling the voltage applied to opposing electrodes. The mass of the ejected ink droplets can thus be variably controlled. Drive at a lower drive voltage is also possible because contact with the opposing wall is propagated from the segment of the diaphragm to the other parts of the diaphragm. A high ink nozzle density is also achieved in an ink jet head using an electrostatic actuator without increasing the drive voltage.
    • 提供改进的喷墨头。 这种改进的喷墨头包括作为墨水室的一部分的隔膜。 隔膜包括通过低于隔膜其余部分的驱动电压接触相对壁的段。 喷墨头还包括与隔膜相对的相对壁。 当产生用于墨滴喷射的压力时,隔膜的部分接触相对的壁,产生非常低的顺应性状态。 在墨滴喷射之后,膜片的分段与相对的壁分离,产生高的柔顺性状态,其通过墨水通道中的振荡吸收在墨水室中产生的压力。 因此,缓冲由包括墨水室的油墨路径中的油墨振动引起的油墨室中的压力,以防止卫星排放。 当在隔膜和相对壁之间形成多个不同的间隙以产生段时,需要不同的驱动电压来接触相对的壁,可以通过适当地控制施加到相对电极的电压来选择有助于墨滴喷射的隔膜的部分。 因此可以可变地控制喷射的墨滴的质量。 在较低的驱动电压下驱动也是可能的,因为与相对壁的接触从隔膜的段传播到隔膜的其它部分。 在使用静电致动器的喷墨头中也可以实现高墨水喷嘴密度,而不增加驱动电压。

    • A drive method of an ink-jet head is provided in which a diaphragm is deformed by means of electrostatic force to eject an ink droplet from a nozzle so as to prevent a residual charge from being created between a diaphragm and an individual electrode. The method has first and second drive modes. In a first drive mode a voltage of a first polarity is applied between a diaphragm of the inkjet head (common electrode) and an individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from a nozzle. In the second drive mode a voltage of a second polarity opposite to the first polarity is applied between the diaphragm and the individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from the nozzle at least once for each operation of ink droplet ejection performed in the first drive mode. According to this method, a residual charge created between the diaphragm and the electrode can be removed concurrently with performing the operation of ink droplet ejection by applying positive and negative drive voltage pulses.
    • 提供了一种喷墨头的驱动方法,其中隔膜通过静电力而变形以从喷嘴喷射墨滴,从而防止在隔膜和单独电极之间产生残余电荷。 该方法具有第一和第二驱动模式。 在第一驱动模式中,在喷墨头(公共电极)的隔膜和单独电极之间施加第一极性的电压,以使隔膜变形并从喷嘴喷出墨滴。 在第二驱动模式中,在隔膜和单独电极之间施加与第一极性相反的第二极性的电压,以使得隔膜变形,并且对于每个墨的操作,墨滴从喷嘴喷射至少一次 在第一驱动模式中执行液滴喷射。 根据该方法,通过施加正驱动电压脉冲和负驱动电压脉冲来执行墨滴喷射的操作,可以同时去除在膜片和电极之间产生的残留电荷。
