摘要： A piezoelectric actuator includes a supporting member in which pressure chambers are formed, a vibration plate which is joined to a joining section of the supporting member, a piezoelectric layer formed on the vibration plate, and an FPC provided on the piezoelectric layer. A contact section of an electrode formed on the piezoelectric layer and a terminal section of the FPC are electrically connected via a bump formed on the terminal section. A recess is formed on an upper surface of the supporting member right below the bump. While joining the piezoelectric layer and a wire member, any damage of the piezoelectric layer and any poor connection do not occur.

摘要： A substrate mounted with an electronic element thereon, comprises a base, an insulator, a fluid passage, and a pressurizer. The base is made of a metal. The insulator is made of a ceramic material and provided on one face of the base. The insulator has a heat-generating electronic element mounted on its side facing contrary to the one face. The fluid passage is formed within the base to have liquid flow therethrough, and radiates heat which has been transmitted from the electronic element via the insulator to the base. The pressurizer applies pressure to the liquid within the fluid passage. The pressurizer includes a pressurizing chamber and an actuator unit. The pressurizing chamber is formed within the fluid passage. The actuator unit changes a volume of the pressurizing chamber by displacing a portion of the insulator corresponding to the pressurizing chamber with respect to a direction perpendicular to the one face.

摘要： An apparatus for ejecting droplets comprises a reservoir, a pressure applicator, a nozzle hole, and a main droplet catcher. In the reservoir, liquid is reserved. The pressure applicator applies pressure to the liquid reserved in the reservoir. The nozzle hole communicates with the reservoir and has an ejection opening that can sequentially eject a main droplet and a satellite droplet having a volume smaller than that of the main droplet. The main droplet catcher is positioned between the nozzle hole and an ejection object so as to come into contact with the main droplet but not with the satellite droplet, to thereby catch the main droplet alone.

摘要： An ink-jet printer includes an ink-jet head which includes a nozzle, a main liquid droplet trapping section 30 which traps only a main liquid droplet, and a cover member which surrounds a space in which a satellite liquid droplet which is jetted from a nozzle at the same time when the main liquid droplet is jetted, flies. It is possible to suppress a decline in an accuracy of a landing position of the satellite liquid droplet, caused due to a change in a trajectory of flying of the satellite liquid droplet due to an effect of a flow of air in the space. Accordingly, it is possible to provide a liquid droplet jetting apparatus which is capable of controlling accurately the landing position of a very small satellite liquid droplet.

摘要： A piezoelectric layer with an individual electrode and a contact point formed thereon, and an FPC having a substrate on which a wiring is formed are in this order arranged on a surface of a channel unit having a pressure chamber. A first through hole is formed in an area, of the substrate, overlapping in a plan view with the contact point, and a second through hole is formed in another area, of the substrate, not overlapping in a plan view with the pressure chamber. An electroconductive material is filled in the first through hole, and a fixing material is filled in the second through hole. Accordingly, it is possible to electrically connect the individual electrode and the wiring of the FPC, and to mechanically connect the piezoelectric layer and the substrate of the FPC.

摘要： An ink-jet printer has a line-type ink-jet head which has a nozzle row including a plurality of nozzles arranged in an array in a scanning direction; an auxiliary head which is movable in the scanning direction and which has a plurality of nozzles arranged in an array in the scanning direction, and a pitch at which the nozzles of the nozzle row are arranged in the ink-jet head and a pitch at which the nozzles are arranged in the auxiliary head are same. Accordingly, when jetting failure occurs concurrently at nozzles among the plurality of nozzles in the ink-jet head, it is possible to complement, at one time, the failed nozzles by the nozzles in the auxiliary head.
