20090267999 | METHOD OF MANUFACTURING LIQUID-JET HEAD AND LIQUID-JET HEAD - Included are the steps of: forming piezoelectric elements on a surface of a passage-forming substrate with a vibration plate in between, and forming a penetrating portion by removing an area in the vibration plate, which area will serve as a communicating portion; forming lead electrodes and sealing up the penetrating portion with an interconnect layer; joining a reservoir forming plate to a surface of a passage-forming substrate; forming liquid passages by wet-etching; forming protection films on inner surfaces of the liquid passages; detaching and removing a protection film on an interconnect layer; and causing a reservoir portion and a communicating portion to communicate with each other by removing a corresponding part of the interconnect layer, and in accordance with the manufacturing method, while the liquid passages are being formed, the communicating portion is formed in a way that an edge of an opening of the vibration plate is located outside an edge of an opening which is close to the penetrating portion, and in a way that at least the edge of the opening of the penetrating portion is thus configured of only any one of the vibration plate and the interconnect layer. | 10-29-2009 |

20120062655 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A liquid ejecting head that includes a fluid channel formation substrate and pressure generation units. The fluid channel formation substrate is made of a silicon single crystal substrate having a crystal face orientation of. The fluid channel formation substrate has a plurality of separate flow channels that include at least pressure generation chambers demarcated by partition walls, each of the pressure generation chambers being in communication with a nozzle opening that ejects liquid drops. The fluid channel formation substrate further has a communication portion that is in communication with each of the separate flow channels. The pressure generation units are provided so as to correspond to the pressure generation chambers and generate a pressure change in the pressure generation chambers so as to cause ejection of liquid drops. | 03-15-2012 |

20090015281 | METHOD OF POSITIONING AN ANISOTROPIC CONDUCTIVE CONNECTOR, METHOD OF POSITIONING THE ANISOTROPIC CONDUCTIVE CONNECTOR AND A CIRCUIT BOARD FOR INSPECTION, ANISOTROPIC CONDUCTIVE CONNECTOR, AND PROBE CARD - The method is a method for positioning a three-layered rectangular frame-like anisotropic conductive connector in order to inspect the electrical properties of an object for inspection. The positioning is carried out in the following manner. The three-layered anisotropic conductive sheet is composed of a first anisotropic conductive sheet, a center substrate and a second anisotropic conductive sheet. Markings and through-holes are formed on the center substrate, and semi-transparent protrusions and through-holes are formed on each of the first anisotropic conductive sheet and the second anisotropic conductive sheet. The markings are identified through the semi-transparent protrusions by detecting means disposed on the side of the first anisotropic conductive sheet and the second anisotropic conductive sheet and thereby the positioning of the semi-transparent protrusions to the markings is carried out, whereby performing the positioning of the first anisotropic conductive sheet, the center substrate and the second anisotropic conductive sheet. | 01-15-2009 |
