摘要： A liquid droplet ejecting head includes: an ejector having a nozzle, a pressure chamber, and a drive element that applies pressure to a liquid inside the pressure chamber; and a controller that applies a drive waveform to the drive element. The controller vibrates a flow velocity of the liquid ejected from the nozzle in a first positive direction vibration mode for causing a leading end portion of the liquid droplet to be ejected from the nozzle toward the opposite side of the pressure chamber side; and a second positive direction vibration mode for adjusting the velocity of a trailing end portion of the liquid droplet. An interval between the first positive direction vibration mode and the second positive direction vibration mode is set so as to make the velocity of the trailing end portion of the columnar liquid droplet faster than the velocity of the leading end portion thereof.

摘要： A channel wafer has a plurality of nozzle flow channels and a common ink reservoir. Pits communicating with the ink reservoir from above heating elements are formed in a polyimide layer on a heater wafer. Each of the pits has a throttled portion in the rear of the heating element and the terminal of a nozzle flow channel is situated on the throttled portion so as to form the minimum sectional area portion of the flow channel. Stable ink discharge characteristics are attained by means of the flow channel resistance of the minimum sectional area portion and bubble pressure is prevented from being relieved toward the ink reservoir. The pressure propagated to the ink reservoir is made to attenuate internally, so that no crosstalk is produced.

摘要： A liquid-drop-ejecting recording head carries out image recording by applying a jetting pulse having a binary digital driving waveform to a piezoelectric element, providing a vibration wave to liquid accommodated in an accommodating chamber, and ejecting a liquid drop from a eject opening. The liquid-drop-ejecting recording head classifies each pixel in accordance with density data thereof. When recording a pixel belonging to a high density range, plural jetting pulses, whose pulse width is ½ times a natural vibration period of a liquid flow at a flow path of the liquid, are applied within a single printing cycle at an interval which is set in advance in accordance with density data of the pixel.

摘要： The present invention provides an inkjet recording head cartridge and an inkjet recording apparatus that have a simple structure and high reliability. Since individual flow passages in which ink emission orifices are formed are communicated directly with a rectangular ink supply chamber, it is prevented that a bubble of such a size as to cause printing defects rises through an ink supply chamber and blocks the individual flow passages. Also, since ink heated within the ink supply chamber is moved upward to the ink tank chamber by convection and grows an air lump sealed beforehand, it is prevented that a bubble will grow in the ink supply chamber. Furthermore, by allocating a large cross-sectional area to the ink supply chamber, it is prevented that meniscus oscillation of the ink emission orifices is amplified by pressure oscillation caused by ink emission and causes a printing defect. Therefore, reliable printing can be performed with a simple construction.

摘要： A droplet ejection apparatus includes an ejecting unit, a driving unit and a correcting unit. The ejecting unit has plural droplet ejection portions that include pressure chambers containing a liquid, ejecting portions ejecting droplets, and driving elements that cause the ejecting portions to eject droplets of a droplet volume in accordance with a driving signal. The driving unit generates a driving signal according to ejection data and applies the driving signal with a predetermined voltage application cycle period. Between different volume droplets, when a difference of the ejection time, from ejection until adhering to a medium, or from application of the driving signal until adhering to the medium, exceeds ½ the voltage application cycle period, the correcting unit corrects the ejection data according to the ejection time difference such that the voltage application timing of the driving signal is corrected by an integer multiple of the voltage application cycle period.
