20090009559 | LIQUID EJECTION HEAD AND METHOD FOR MANUFACTURING LIQUID EJECTION HEAD - The present invention provides liquid ejection head enables a reduction in the distance between a print medium and an ejection port formation face of the liquid ejection head on which an ejection port is formed, improving the landing accuracy of droplets ejected from the liquid ejection head. A print head according to the present invention includes an element substrate and a supporting member. A supporting portion is located in the space between the element substrate and the supporting member. Connection wiring is formed on the supporting portion. The connection wiring is provided which connects wiring inside of the supporting member provided in the supporting member to the heat generating element. | 01-08-2009 |
20100201744 | INKJET RECORDING HEAD - A liquid jet recording head includes a substrate including a plurality of discharge energy generating elements, and a plurality of ink supply ports positioned along an array direction of the plurality of discharge energy generating elements and separated from each other by beams, a plurality of ribs supported by the beams, and an orifice plate supported by the plurality of ribs, wherein the orifice plate includes discharge ports for discharging liquid droplets which enter from the plurality of ink supply ports and is provided with discharge energy by the plurality of discharge energy generating elements. | 08-12-2010 |
20110225824 | METHOD FOR MANUFACTURING INK JET RECORDING HEAD - There is provided a method for manufacturing an ink jet recording head in which a plurality of recording element substrates used for discharging ink are appropriately arranged onto a support substrate. | 09-22-2011 |
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 |
20130100208 | METHOD OF MANUFACTURING LIQUID EJECTION HEAD AND LIQUID EJECTION HEAD - A method of manufacturing a liquid ejection head includes: defining a first imaginary reference line along the longitudinal direction of a base member and measuring the distances between the first imaginary reference line and at least two liquid supply port portions of a liquid supply port row, including defining a second imaginary reference line passing the liquid supply port portion at the shortest distance from the first imaginary reference line and the liquid supply port portion at the longest distance from the first imaginary reference line respectively from among the at least two liquid supply port portions and defining the second imaginary reference line between two imaginary lines parallel to the first imaginary reference line. | 04-25-2013 |
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 |
20140333692 | LIQUID EJECTION HEAD AND METHOD FOR FABRICATING THE SAME - There is provided a liquid ejection head that can reduce trouble in alignment of a print element substrate even in the case where a high magnification optical system is used and a method for fabricating the liquid ejection head. To achieve this, an auxiliary mark that indicates a relative position with respect to a reference mark is detected and recognized, and thus the position of the reference mark is identified even in the case where the reference mark is not reflected in a camera. | 11-13-2014 |
