20080239013 | LIQUID DISCHARGING HEAD, LIQUID DISCHARGING APPARATUS, AND BUBBLE REMOVING METHOD FOR THE LIQUID DISCHARGING APPARATUS - A liquid discharging head includes a head chip including a plurality of energy generating elements configured to discharge liquid, and liquid chambers provided around the energy generating elements, and a common passage member configured to define a common passage communicating with all the liquid chambers. Liquid is discharged from the liquid chambers by driving the energy generating elements so as to apply a discharging force to the liquid. N-number of common passage members (N≧2) are provided, and each includes an inlet for supplying the liquid to the common passage and an outlet for ejecting the liquid from the common passage. The inlet of the first common passage member is connected to a liquid supply member. The inlet of the N-th common passage member is connected to the liquid supply member via an opening-closing valve and to the outlet of the (N-1)-th common passage member. | 10-02-2008 |
20080239014 | Liquid discharging head and liquid discharging apparatus - A liquid discharging head includes a head chip including a plurality of energy generating elements configured to discharge liquid and liquid chambers provided around the corresponding energy generating elements, and a common passage member configured to define a common passage communicating with all the liquid chambers in the head chip. the liquid is discharged from the liquid chambers by driving the energy generating elements so as to apply a discharging force to the liquid. The common passage member includes an inlet through which the liquid is supplied to the common passage, and an outlet through which the liquid is ejected from the common passage. The common passage includes a ceiling surface having a groove extending from the inlet toward the outlet. | 10-02-2008 |
20090056768 | LIQUID EJECTION HEAD, LIQUID EJECTION APPARATUS, AND MANUFACTURING METHOD OF LIQUID EJECTION HEAD - A liquid ejection head includes an energy-generating element arranged on a semiconductor substrate, a barrier layer deposited on the semiconductor substrate for forming a liquid chamber in the periphery of the energy-generating element, and a nozzle sheet bonded on the barrier layer and having a nozzle formed at a position opposing the energy-generating element, in which the liquid ejection head ejects liquid contained in the liquid chamber from the nozzle as liquid droplets by the energy-generating element, and the barrier layer is provided with a plurality of depressions, each having an independent contour, arranged within a range, which is separated from the border of the barrier layer, on an adhesive region adhering to the nozzle sheet. | 03-05-2009 |
20090085955 | LIQUID EJECTION HEAD, LIQUID EJECTION APPARATUS, AND MANUFACTURING METHOD OF LIQUID EJECTION HEAD - A liquid ejection head includes an energy-generating element arranged on a semiconductor substrate, a barrier layer deposited on the semiconductor substrate for forming a liquid chamber in the periphery of the energy-generating element, and a nozzle sheet bonded on the barrier layer and having a nozzle formed at a position opposing the energy-generating element, in which the liquid ejection head ejects liquid contained in the liquid chamber from the nozzle as liquid droplets by the energy-generating element, and the barrier layer is provided with a plurality of depressions, each having an independent contour, arranged within a range, which is separated from the border of the barrier layer, on an adhesive region adhering to the nozzle sheet. | 04-02-2009 |
20100026739 | LIQUID SUPPLYING DEVICE, LIQUID DISCHARGING DEVICE, AND METHOD OF CONTROLLING LIQUID DISCHARGING DEVICE - A liquid supplying device includes a liquid tank storing liquid that is supplied to a consumption object that consumes the liquid, a transfer pump for transferring the liquid stored in the liquid tank, an auxiliary tank temporarily storing the liquid transferred by the transfer pump before supplying the liquid to the consumption object, and a return pipe disposed so as to return the liquid to the liquid tank from the auxiliary tank when an amount of the liquid stored in the auxiliary tank becomes greater than or equal to a certain amount. | 02-04-2010 |
20100026764 | DROPLET DISCHARGE HEAD AND DROPLET DISCHARGING UNIT INCORPORATING THE SAME - A droplet discharge head includes: a liquid reservoir which holds a liquid; a channel through which the liquid is guided to the liquid reservoir; and a driving element which changes the pressure in the liquid reservoir so as to discharge droplets of the liquid contained in the liquid reservoir through a nozzle, in which wall surfaces of the liquid reservoir and of the nozzle are arranged in a continuous line at a side opposite the channel with respect to the center of the nozzle as seen in a cross-sectional view through a central axis of the nozzle. | 02-04-2010 |
20100140862 | PRINTER - A second driven roller that is rotated by following a second driving roller has a larger outer diameter than a first driven roller. A front edge of a recording sheet being lifted up from a first nip contacts the second driven roller, and hence the front edge does not directly hit the first driven roller. The second driven roller rotates at a higher rotational speed than a rotational speed of the first driven roller. The second driven roller gently flips the front edge of the recording sheet which has contacted the second driven roller, and leads the front edge quickly to the first nip. The front edge of the recording sheet is smoothly led to the nip. | 06-10-2010 |
20100201724 | LIQUID DISCHARGE APPARATUS AND METHOD OF CONTROLLING LIQUID DISCHARGE APPARATUS - A liquid discharge apparatus includes: a plurality of nozzles that discharges liquid; a liquid discharge head that includes nozzle arrays where the respective nozzles are arranged in one direction; a liquid adsorbent that adsorbs liquid attached to a portion of the liquid discharge head where the nozzle arrays are formed; a moving means for relatively moving the liquid adsorbent in an arrangement direction of the nozzles; and a liquid suction means for sucking liquid adsorbed in the liquid adsorbent. | 08-12-2010 |
20100201738 | LIQUID DISCHARGE APPARATUS - A liquid discharge apparatus includes: nozzles discharging liquid; a liquid discharge head including nozzle arrays where the nozzles are arranged in one direction; a liquid adsorbent adsorbing liquid attached to a portion of the liquid discharge head where the nozzle arrays are formed; a moving means for relatively moving the liquid adsorbent in an arrangement direction of the nozzles; support rollers supporting the liquid adsorbent so as to allow the liquid adsorbent to rotate; a rotating shaft corresponding to the axis of rotation of the support roller and being rotated in a normal or reverse direction by using the relative movement of the liquid adsorbent, which is caused by the moving means, as a source of power; and a reverse rotation preventing means for transmitting the normal rotation of the rotating shaft to the support roller and not transmitting the reverse rotation of the rotating shaft to the support roller. | 08-12-2010 |
