    摘要： PROBLEM TO BE SOLVED: To provide an ink jet print head, more particularly, an ink jet print head in which an ink backflow phenomenon that occurs in an ink ejection process is effectively reduced.SOLUTION: The ink jet print head includes: a first substrate on which a first restrictor and a pressure chamber are formed; and a second substrate on which a manifold and a second restrictor are formed. The first restrictor is capable of being connected to the manifold and the second restrictor, and the second restrictor is capable of being connected to the first restrictor and the pressure chamber.

    摘要： PROBLEM TO BE SOLVED: To provide a liquid ejecting head in which problems in ejection due to the entrainment of bubbles are less likely to occur, and a method of manufacturing the same. SOLUTION: The liquid ejecting head has a nozzle substrate made of crystalline material, in which a nozzle 8 through which ink is ejected is provided by etching process. The nozzle includes a plurality of continuous nozzle sections having different diameters arranged coaxially in the direction of the thickness of the crystalline material. The nozzle sections include a first nozzle section 8a that is located nearest to the ejection side and has a first diameter D1, and a second nozzle section 8b that is continuous with the first nozzle section and has a second diameter D2 larger than the first diameter. The difference between the first diameter and the second diameter is not less than 0.1 and not greater than 0.4 relative to the first diameter. COPYRIGHT: (C)2011,JPO&INPIT

    摘要： PROBLEM TO BE SOLVED: To provide an ink-jet head capable of preventing nozzle clogging, which is caused by residual droplets, by ensuring a moving path of the residual ink adhering to nozzles by providing moving grooves.
    SOLUTION: The ink-jet head is an ink-jet head which prevents nozzle clogging caused by the residual droplets adhering to the nozzles. The ink-jet head includes a head body having a surface on which nozzles are provided and an actuator for providing a pressure to the interior of the head body. On the surface of the head body, the moving grooves for ensuring the path through which the residual droplets move are provided so as to be away from the nozzles.
