The film provides an efficient seal for the reservoirs and also positions the electrodes on the side of the piezoelectric element in which motion is effected, which can reduce the magnitude of the drive voltage. This location of the compliant flex print material also can enhance electrical and mechanical isolation between reservoirs, which improves jetting accuracy. The compliance of the polymer also reduces strain on the ink jet head. | 2009-03-26 |
20090079802 | INKJET PRINTING APPARATUS AND METHOD FOR AGITATING INK - In order to recover unevenness in concentration of ink ejected from a print head, an agitation operation of agitating ink by causing the print head to reciprocate is carried out. This agitation operation sets a number of times of moving the print head for agitation according to a condition, such as a printing mode, for a reciprocating motion in a main scanning direction of the print head in printing. | 2009-03-26 |
20090079803 | INK CARTRIDGE AND ITS RECYCLING METHOD - An ink cartridge including a main body, a cover member, and an insulating seal member, which are components for constituting the ink cartridge for an inkjet printer, wherein the main body and the cover member are bonded to each other with an electrically-disbonding adhesive having a characteristic of causing a bond dissociation with a passage of an electric current so as to form an ink storing section, the main body has a first electrode for passing the electric current through the electrically-disbonding adhesive, the cover member has a second electrode for passing the electric current through the electrically-disbonding adhesive, the seal member is arranged in the vicinity of a bonding portion where the main body and the cover member are bonded to each other so as to prevent an ink stored in the storing section from being in contact with the first and the second electrodes. | 2009-03-26 |
20090079804 | Liquid Container and Liquid Injection Device - A liquid container is constructed to store a liquid and supply the liquid to a liquid injection device in response to inflow of a pressurized fluid from the liquid injection device. The liquid container comprises: a flow inlet formed to allow the pressurized fluid to be flowed in from the liquid injection device; a liquid reservoir formed to store the liquid therein; a supply inlet formed to connect with the liquid reservoir and supply the liquid, which is flowed out of the liquid reservoir in response to the inflow of the pressurized fluid, to the liquid injection device; and a pressure detector that identifies a pressure status of the pressurized fluid flowed in from the liquid injection device. The liquid container of this structure enables easy determination of whether the pressurized fluid is normally supplied to the liquid container. | 2009-03-26 |
20090079805 | INK CARTRIDGES AND INK SUPPLY SYSTEMS - An ink cartridge has a case which has an ink chamber, a first wall facing an exterior of the case, and a translucent portion at the first wall and having an inner space formed therein continuously with the ink chamber. The ink cartridge has a first movable member positioned in the case, and a second movable member coupled to the case. The first movable member moves relative to an amount of ink stored in the ink chamber, and has a signal blocking portion positioned in the inner space. The second movable member has a second wall that faces the first wall and that has an opening therethrough. The second movable member moves between a first position and a second position. The second wall is closer to the first wall when the second movable member is in the second position than when the second movable member is in the first position. | 2009-03-26 |
20090079806 | PRINTHEAD HAVING LOW PRESSURE RISE NOZZLES - A printhead is provided having a plurality of chambers on a substrate which each have a nozzle, a heater arranged in each chamber so as to heat fluid within the chamber to form a gas bubble therein and thereby cause ejection of a drop from the corresponding nozzle, and a plurality of passages formed in the substrate so that each passage supplies the fluid to an associated one of the chambers. Each chamber is configured so that the transient rise in pressure therein when the gas bubble is formed is less than 20 MPa. | 2009-03-26 |
20090079807 | RECORDING APPARATUS AND RECORDING MATERIAL - A recording apparatus includes an intermediate transfer member, a supply unit that supplies onto the intermediate transfer member a curable solution containing a cationic curable material that is cured by a cationic curing reaction upon application of an external stimulus, a discharge unit that discharges an ink containing a recording substance to a layer to be cured that has been formed by the curable solution supplied onto the intermediate transfer member, a transfer unit that transfers, from the intermediate transfer member to a recording medium, the layer to be cured to which the ink is discharged, and a stimulus supply unit that supplies a stimulus that cures the layer to be cured. | 2009-03-26 |
