    摘要： A method of driving an ink-jet recording head which is provided with nozzle openings, pressure generating chambers each communicating with reservoirs via ink supply ports and keeping the Helmholtz resonance frequency with a period Tc, and piezo-electric vibrators for expanding and contracting the respective pressure generating chambers. The method of driving the ink-jet recording head comprises a first step of expanding the pressure generating chamber, a second step of maintaining the expanded condition, and a third step of causing an ink droplet to be jetted from the nozzle opening by contracting the pressure generating chamber thus expanded. The duration of the second step is set not greater than 1/2 of the period Tc of the Helmholtz resonance vibration in order to prevent the generation of satellites and ink mists resulting from the swollen-back meniscus by minimizing the meniscus vibration, so that the driving at a high driving frequency is made possible by shorting the attenuation time of the meniscus corresponding to its reduced vibration.

    摘要： In an ink jet type recording head, a flow passage forming substrate includes pressure generating chambers which are communicated with nozzle openings respectively, a common ink chamber for supplying ink to the pressure generating chambers; and ink supply inlets through which the pressure generating chambers are communicated with the common ink chamber. Each of the ink supply inlets is so designed that it has a narrow part, and it is gradually larger from the narrow part towards the pressure generating chamber, whereby the ink supply inlet is increased in length without changing the flow resistance, and the bonding area near the ink supply inlet is increased.

    摘要： A printer using a line-type ink jet recording head. The line-type head has pressure producing chambers formed by dividing nozzle openings extending in a recording paper width direction with vertical side walls and upper and lower ink flow paths which communicate with each other through the pressure producing chambers and extend in a horizontal direction. Each ink flow path has an inlet for replenishing ink and an outlet for discharging the ink. A plurality of pressure producing elements are provided for applying varied pressures to the pressure producing chambers for jetting ink droplets. A sealing member selectively seals the nozzle openings by abutting on the nozzle openings when the recording head has been evacuated to a predetermined position. An ink tank is connected to the inlets and the outlets through pipes, and an ink stream producing device is arranged in the pipes, for producing streams causing the ink to flow from the ink tank to the lower ink flow path and then to the upper ink flow path through the pressure producing chambers.

    摘要： In an ink jet apparatus for manufacturing a color filter 1, ink jet heads 22 having a plurality of nozzle 27 are disposed in a linear manner. Filter element member is ejected to a motherboard 12 from a plurality of nozzles 27 four times so as to form the filter element 3 in a predetermined thickness. By doing this, it is possible to prevent difference in the thickness in a plurality of the filter elements 3 and to equalize light transparency in planar manner. Thus, in an ejecting apparatus, a color filter can be formed in more common way at low cost and more efficiently. Also, it is possible to provide an ejecting apparatus which can equalize factors such as electrooptical characteristics of the electrooptical members, color displaying characteristics by the liquid crystal apparatuses, and illuminating characteristics by an EL surface.
