20080237047 | Liquid Transporting Apparatus - A head includes a common ink chamber, a plurality of individual electrodes which communicate with the common ink chamber, and a plurality of ink channels through which, an ink supplied from the common ink chamber flows. Each ink channel is provided with a first electrode which is common for the individual electrodes, a plurality of second electrodes corresponding to the individual electrodes respectively, and an insulating layer which covers the first electrode and the second electrodes. Furthermore, the individual electrode of each ink channel is associated with an individual electrode of another ink channel, and the corresponding second electrodes are in electrical conduction. Accordingly, it is possible to reduce a cost of an electrical system by reducing the number of wirings which are connected to electrodes provided to each of the liquid channels. | 10-02-2008 |
20090051723 | Liquid transporting apparatus - An ink transporting head includes a head main body in which, an ink channel is formed, a transporting electrode which is arranged on an inner surface of the ink channel, an insulating layer which is arranged on the inner surface of the ink channel to cover the transporting electrode, and which changes a wetting angle of liquid on a surface according to an electric potential of the transporting electrode, and a heat generator which heats the ink inside the ink channel. Accordingly, there is provided a liquid transporting apparatus which is capable of suppressing a temperature fluctuation of the liquid inside the liquid channel, and transporting the liquid stably. | 02-26-2009 |
20090051739 | Liquid delivering apparatus and method of producing the same - A liquid delivering apparatus, including a flow-passage unit including an opening and a pressure chamber which accommodates liquid and which communicates with the opening; an oscillating plate which partially defines the pressure chamber; a piezoelectric material layer which is one of directly and indirectly stacked on the oscillating plate and which deforms upon application of an electric field thereto so as to oscillate the oscillating plate for delivering the liquid from the pressure chamber through the opening; and an electrode pattern and a drive circuit which apply the electric filed to the piezoelectric material layer. The drive circuit and the electrode pattern are one of directly and indirectly provided on the oscillating plate. | 02-26-2009 |
20090135230 | Liquid Ejecting Apparatus, Method For Manufacturing Liquid Ejecting Apparatus, And Ink-Jet Printer - An ink-jet head includes a common liquid chamber, a plurality of pressure chambers, a plurality of nozzles which eject ink, a plurality of individual ink channels communicating with the common liquid chamber, the pressure chambers and the nozzles, and a piezoelectric actuator which selectively varies the volume of the plurality of pressure chambers. The common liquid chamber is disposed on the side opposite to the nozzles with respect to the piezoelectric actuator. A through-hole which forms a part of the individual ink channels is formed in the piezoelectric actuator. This structure ensures a large region in which the nozzles can be disposed, and allows the nozzles to be arranged at higher density. | 05-28-2009 |
20090160918 | INK CARTRIDGE AND INKJET RECORDING SYSTEM - An ink cartridge includes a cartridge main body and a pivoting member. The cartridge main body has an ink accommodating chamber accommodating ink therein and an ink outlet outputting ink in the ink accommodating chamber toward the inkjet recording device. The pivoting member is pivotably supported by the cartridge main body and that has a lid member configured of closing the ink outlet. The pivoting member pivots to move the lid member between a closing position and an opening position. The lid member closes the ink outlet at the closing position. The lid member opens the ink outlet at the opening position. | 06-25-2009 |
20090179925 | LIQUID CARTRIDGE AND LIQUID EJECTING SYSTEM - A liquid cartridge is detachably mounted in a liquid ejecting device, and supplies liquid to the liquid ejecting device when mounted. The liquid cartridge includes a liquid accommodating chamber, a float member movably disposed in the liquid accommodating chamber, and a detection member moving in conjunction with the float member and being subject to be detected by an external light detector for determining remaining amounts of liquid in the liquid accommodating chamber. A part of the detection member is located at a detection position located above an uppermost liquid surface reached when a predetermined maximum amount of liquid is accommodated in the liquid accommodating chamber. At least a part of the liquid accommodating chamber has light transmissive characteristics so that light from the light detector can reach the detection position. The detection member passes the detection position in conjunction with the float member. | 07-16-2009 |
20090267986 | LIQUID JETTING APPARATUS - A plurality of ink cartridges are installed to be arranged in a vertical direction. A carriage reciprocates in the vertical direction. An ink-jet head has nozzle rows arranged, in a row in the vertical direction, to be parallel mutually, and the ink cartridge is connected to the nozzle row via a tube. There is provided a vertically long and a stylish liquid jetting apparatus which can be installed vertically even in a narrow area. | 10-29-2009 |
20130293614 | INK-JET PRINTER - An ink-jet printer including: an ink supply portion; a transport mechanism; an ink-jet head; an inverting mechanism; and a controller is provided. The controller is configured to control the ink-jet head to perform an ordinary jetting operation and a marking jetting operation, and is configured to control the ink-jet head and the inverting mechanism such that only the ordinary jetting operation is performed on the one surface of the printing medium without performing the marking jetting operation, and the marking jetting operation is performed on the other surface of the printing medium after inverting the printing medium with the inverting mechanism. | 11-07-2013 |
20140333701 | Method for Manufacturing Piezoelectric Actuator - A method for manufacturing a piezoelectric actuator is disclosed that includes forming a vibration plate, forming a plurality of electrodes on the vibration plate, forming a piezoelectric layer on the electrodes, and forming a common electrode on the piezoelectric layer. | 11-13-2014 |
