20090151858 | Inkjet head and method for manufacturing the same - An inkjet head includes a channel unit and actuator units. Inside the channel unit, individual ink channels are formed so that ink supplied from ink inlets is ejected from nozzles via pressure chambers. The actuator units are bonded to the upper surface of the channel unit. The actuator units have a configuration of four piezoelectric sheets laminated to one another. On the upper surface of the piezoelectric sheet, individual electrodes are disposed in positions opposed to the pressure chambers respectively. A FPC for supplying driving signals to the actuator units is connected to the individual electrodes. | 06-18-2009 |
20090167820 | Inkjet Head - An inkjet head may comprise an ejection port which ejects ink and an ink flow path which supplies the ink to the ejection port. The inkjet head may also comprise an ejection actuator which supplies ejection energy to the ink in the ink flow path. The ejection energy may cause the ink to be ejected from the ejection port. The inkjet head may also comprise a wall portion. The wall portion may be located at a position farther from the ejection port along the ink flow path with respect to a position at which the ejection energy is supplied. The wall portion may define an inner wall surface of the ink flow path. The wall portion may deform to decrease a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as a temperature of the ink in the ink flow path increases. The wall portion may deform to increase a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as the temperature of the ink in the ink flow path decreases. | 07-02-2009 |
20090244174 | IMAGE RECORDING APPARATUS - An image recording apparatus including an ink-jet head having four ink supply passages, manifold passages communicating with the respective ink supply passages, and individual ink passages extending from the common passages to nozzles open in an ink ejecting surface, wherein groups of the nozzles communicating with the respective manifold passages are open in respective unit areas u | 10-01-2009 |
20090244228 | LIQUID DISCHARGING HEAD AND METHOD FOR MANUFACTURING THE SAME - A liquid discharging head is provided. The liquid discharging head has a flow path unit in which a common liquid flow path for supplying liquid to a nozzle which discharges liquid is formed by a plurality of plates being stacked together, the plurality of plates including a damper plate of which one surface defines at least a part of a wall surface of the common liquid flow path and an area on an other surface which is opposed to the common liquid flow path across the damper plate is not in contact with the plurality of plates other than the damper plate, wherein compression stress along the wall surface is applied to a portion of the damper plate which configure a wall of the common liquid flow path. | 10-01-2009 |
20100194801 | Recording Apparatus - A recording apparatus of the present invention includes: a droplet ejection head including an inflow passage, a common fluid passage, and a plurality of individual fluid passages each extending to an ejection opening; a supply mechanism capable of forcedly supplying a fluid to the inflow passage; a wiper made of an elastic material; and a moving mechanism which moves the wiper. The fluid forcedly supplied to the inflow passage and discharged from each ejection opening does not drop from the ejection face, and at least a predetermined amount of the fluid discharged from each ejection opening is retained on the ejection face when the wiper traverses the relevant ejection opening. | 08-05-2010 |
20100245438 | RECORDING APPARATUS, METHOD OF CONTROLLING RECORDING APPARATUS AND COMPUTER READABLE RECORDING MEDIUM - Flushing data include pixels that are flushing dot candidates in a virtual area where a plurality of pixels are arranged in a matrix. One or less pixel is arranged in a plurality of rows of pixels arranged in lines extending in the main scan direction and the direction of conveyance of a sheet and third and fourth directions that are orthogonal to each other and that cross each other at an angle of 45°. A head control section controls an inkjet head such that image dots and flushing dots corresponding to flushing dot candidates that pertain to flushing data and that are situated at locations where no image dots are generated, are produced on a sheet. | 09-30-2010 |
20100245448 | RECORDING APPARATUS - A recording apparatus including: a head having an ejection surface; and a recording-medium conveyor device having a conveyor member with a conveyor surface, wherein the apparatus further includes a first and a second attraction device each for permitting the medium on the conveyor surface to be attracted thereto. The first device includes: a first and a second electrode each being opposed to one surface of the medium opposite to another surface thereof facing the ejection surface; and a first voltage applicator to apply a voltage between the first and second electrodes. The second device includes: an electrifying body and a third electrode between which at least one of the medium and the conveyor member is sandwiched; and a second voltage applicator to apply a voltage between the electrifying body and the third electrode. The second device is for electrifying the at least one of the medium and the conveyor member. | 09-30-2010 |
