摘要： An ink-jet head includes pressure chambers arranged in a row in a row-direction, and a manifold flow passage communicated with the pressure chambers and extending in the row-direction. An ink inflow port is formed at one end of the manifold flow passage. The manifold flow passage has a main portion, a connecting portion, and an extended portion which are arranged in this order from a side close to the ink inflow port. The manifold flow passage is communicated with the pressure chambers at the main portion. The main portion has a constant cross-sectional area greater than that of the connecting portion. A cross-sectional area of the extended portion is greater than that of the connecting portion. The pressure wave, generated in the pressure chamber and propagated to the manifold flow passage, can be efficiently attenuated by the manifold flow passage constructed as described above.

摘要： An ink jet recording apparatus wherein each dot, having the same size, may be formed regardless of whether print commands are successive. The ink jet recording apparatus includes a first drive waveform and a second drive waveform wherein the second drive waveform is used when there is no dot printed immediately before a dot is to be printed and the first drive waveform is used when there is a dot printed in response to a print command immediately before a dot is to be printed. Thus, regardless of whether the first drive waveform or the second drive waveform is used, the same volume of ink droplets are ejected and the same sized dots are formed.

摘要： When a dot is formed apart from other dots on a print medium, in response to a discontinuous print command, a first drive waveform is used. The first drive waveform includes an ejection pulse and an ink droplet reducing pulse for retrieving a portion of an ink droplet about to leave the nozzle. When a dot is formed to overlap other dots on a print medium, in response to one of continuous print commands, the second drive waveform is used. The second drive waveform includes an ejection pulse and an ejection stabilizing pulse for suppressing residual vibrations generated by the ejection pulse. By selectively using the first or the second drive waveform, an ink droplet smaller than 20 pl can be ejected stably even at high printing frequencies. As a result, high-quality, high-speed printing can be achieved.

摘要： A droplet-jetting device, which is usable for an ink-jet recording apparatus, comprises a pressure chamber disposed between a cavity plate and a pressure-generating section of a piezoelectric actuator. The pressure-generating section and the cavity plate are connected by a connecting section. When a voltage is applied to the piezoelectric actuator, the pressure-generating section is elongated to depress the bottom of the pressure chamber downwardly so that the volume of the pressure chamber is increased. The droplet-jetting device is realized, in which the area of arrangement of the pressure-generating section is decreased to suppress the electrostatic capacity and the pull-eject can be performed by applying the voltage only when the device is driven.

摘要： In an ink droplet ejecting method and apparatus, when a continuous dot printing is performed and also when a continuous dot printing is followed by a one-dot rest and again subsequent printing, it is intended to suppress the meniscus oscillation of ink, prevent the decrease in ink droplet ejecting speed of some dots and prevent the ink droplet ejecting direction from becoming unstable. A plurality of driving waveforms are provided in advance, and in accordance with whether there is ink ejection just before and just after one dot, an appropriate driving waveform for the dot is selected, whereby it becomes possible to suppress the meniscus oscillation of ink and a stable ink droplet ejection is ensured in a continuous dot printing and also when a continuous dot printing is followed by a one-dot rest and against subsequent printing.
