摘要： Disclosed herein is a piezoelectric actuator comprising a plurality of driving columns separated by grooves in which the width of each driving column in the direction of the groove width widens from the displacement output surface to the substrate. The widening of the diving column width toward the substrate realizes a piezoelectric actuator having a high strength and a high reliability capable of stably and effectively generating an output displacement.

摘要： A pressurizing unit for pressurizing ink filling a pressure chamber in response to an electric signal is constructed with a beam and a support portion. The support portion is preferably formed integrally with the beam and supports the beam at opposite end portions thereof. The support portion receives a bending force and a shearing force, with are generated at the opposite end portions by a buckling deformation of the beam when the beam is expanded in its longitudinal direction by an application of the electric signal.

摘要： A piezoelectric actuator has a base, and an array of drive columns separated by grooves and each having a top surface for outputting a displacement force. Each of the drive columns is formed in a unitary body with an underlying portion of the base by a first block of a plurality of green sheets made of a piezoelectric material and stacked together. The base has additionally a second block of green sheets stacked between adjacent two of the first block at the portion of the base underlying the groove.

摘要： The present invention provides an inkjet recording head and inkjet recording device which can eject a high viscosity ink at ordinary temperature. The inkjet recording head has a nozzle portion ejecting an ink drop; an ink flow path member including the nozzle portion; and a driving section moving the ink flow path member in an ink drop ejecting direction and an opposite direction. The driving section moves the ink flow path member in the ink drop ejecting direction, and applies inertia in the ejecting direction to internal ink by one of suddenly stopping the ink flow path member and moving the ink flow path member in the opposite direction, and makes the ink drop be ejected from the nozzle portion.

摘要： The present invention provides an ink-jet recording head. The ink-jet recording head includes a nozzle that ejects an ink droplet; an ink flow path member that includes the nozzle; a beam member connected to the ink flow path member or which includes the ink flow path member; a first drive component connected with and set at the beam member and which bends the beam member; and a second drive component that deforms the beam member so as to become convex from concave in the ink droplet discharging direction. The second drive component deforms the beam member so as to become convex from concave in the ink droplet discharging direction and the first drive component bends the beam member. Thereby, the beam member is buckling reverse deformed with the second drive component.
