20110122202 | LIQUID-EJECTING RECORDING HEAD AND METHOD OF PRODUCING THE SAME - A method of producing a recording head including a substrate provided with an element that generates energy utilized for ejecting a liquid, a wiring member that is connected to the substrate, and a supporting member that supports the substrate and the wiring member includes applying a sealant to a region existing between a side surface of the substrate and the supporting member through a communicating path that connects the region to an outer peripheral area of the supporting member. | 05-26-2011 |
20110209335 | METHOD FOR MANUFACTURING INK JET CARTRIDGE - A predetermined amount of an ink absorber, which is a fiber assembly in which intersections between fibers are not fused together, is charged into a compression and insertion apparatus. A rectangular parallelepiped-shaped insertion block is moved to an upper surface portion of the absorber, and one face of the ink absorber is pushed by a side plate. As such, a part excluding the part of the ink absorber which faces the side plate is compressed and surrounded. In this state, the ink absorber is compressed by the side plate. The ink absorber is inserted into a tank case by making a bottom plate slide, thereby opening the bottom face of the ink absorber and by moving down the insertion block. | 09-01-2011 |
20110211028 | INK JET CARTRIDGE AND MANUFACTURING METHOD OF INK JET CARTRIDGE - The ink jet cartridge includes a tank case that has a space having a opening, a lid that closes the opening, an ink accommodating section that is formed with the space of the tank case and the lid, and an ink absorber that is accommodated in the ink accommodating section. Also, an atmosphere communication port that passes through the lid and a projection section that projects to the space of the tank case are provided in the lid. The ink absorber consists of a fiber aggregate, and a welding section in which the fibers are combined to each other and an unwelded section in which the fibers are not combined to each other are provided on a surface that faces the lid. | 09-01-2011 |

20120293588 | FLOW PASSAGE ASSEMBLY AND METHOD FOR MANUFACTURING FLOW PASSAGE ASSEMBLY, INKJET RECORDING HEAD, AND RECORDING APPARATUS - A method for manufacturing a flow passage assembly includes forming a first flow passage in a first joint interface formed by welding a first surface of a first flow passage forming member to a first surface of a second flow passage forming member using an ultrasonic welding process, and forming, after the first flow passage is formed, a second flow passage in a second joint interface formed by welding a first surface of a third flow passage forming member to one of a second surface of the first flow passage forming member and a second surface of the second flow passage forming member using an ultrasonic welding process. A total area of weld portions used when the first flow passage is formed is greater than a total area of weld portions used when the second flow passage is formed. | 11-22-2012 |
20130063523 | LIQUID RECORDING HEAD AND METHOD OF MANUFACTURING THE SAME - Provided is a liquid recording head in which a protective layer having resistance to liquid and an adhesiveness improving film are disposed on a second surface opposite to a first surface of a silicon substrate. The first surface and the second surface have a plane direction. The protective layer is disposed in a peripheral region of an opening of a liquid supply port. A liquid ejection chip is bonded to a head substrate with an adhesive so that the liquid supply port communicates to a liquid introduction port on a side of the second surface of the silicon substrate. | 03-14-2013 |
20140216630 | METHOD OF MANUFACTURING LIQUID DISCHARGE HEAD - A method of manufacturing a liquid discharge head in which a device substrate having an energy generating element and a supply port and a supporting member having a supply passage are bonded with each other an adhesive agent includes:

20140218445 | METHOD OF MANUFACTURING LIQUID EJECTION HEAD, AND LIQUID EJECTION HEAD - There is provided a method of manufacturing a liquid ejection head that includes a supporting member having a major surface provided with a plurality of supply paths, and a recording element substrate having a bonding surface bonded to the major surface and provided with a plurality of supply ports arranged side by side in an arranging direction in which the supply paths are arranged side by side, the supply ports having smaller widths than the respective supply paths in the arranging direction. The method includes applying a bonding agent on the major surface around each of the supply paths, spreading the bonding agent to inner side surfaces of the supply ports by pressing boundary portions between the bonding surface and the supply ports into the bonding agent applied, and bonding the bonding surface to the major surface at a bonding position where the supply ports face the respective supply paths. | 08-07-2014 |
20140362144 | FLUID PATH STRUCTURE AND METHOD OF MANUFACTURING THE SAME - A fluid path structure is manufactured by way of an aligning step of aligning a first resin part with a second resin part by inserting a projection formed on the first resin part into a corresponding hole formed in the second resin part and a welding step of welding joint surfaces of the first resin part and the second resin part, thereby forming a fluid path. The aligning step is executed so as to narrow the gap between the projection and the hole to a minimum at a base side of the projection relative to a half of the height of the hole and the welding step is executed only at the base side of the projection relative to the half of the height of the hole so as to make the lateral surface of the projection only partially contact with the lateral surface of the hole. | 12-11-2014 |
