摘要： An actuator for an ink jet printer includes: an ink tank comprising a thick substrate having a cavity structure and a vibrating plate covering a cavity; and a piezoelectric/electrostrictive working portion comprising an upper electrode layer, a lower electrode layer, and a piezoelectric/electrostrictive layer between the electrode layers, the piezoelectric/electrostrictive working portion being disposed on the ink tank so that the lower electrode layer contacts with the vibrating plate. The upper electrode is trimmed only in the portion where the piezoelectric/electro-strictive layer covers the vibrating plate so as to control an effective electrode area and adjust an ink jet volume to be appropriate. The upper electrode layer is trimmed with the piezoelectric/electrostrictive layer covering the vibrating plate at least near the portion to be trimmed of the upper electrode layer so as to control an effective electrode area and adjust an ink jet volume.

摘要： A method of inspecting a crack in a ceramic substrate that is not exposed on the surface. The method can detect all cracks and make objective judgement possible by expressing the inspection result as numerical data. Conductors are disposed on both faces of a ceramic substrate, wherein one of the conductors is a conductive liquid; the insulation resistance value or an electric property dependent on the insulation resistance is measured with the conductive liquid or other conductors electrically connected to the conductive liquid which are used as electrodes.

摘要： A recess is formed in a surface confronting an actuator unit of an ink supply inlet forming substrate. When a flow path unit and the actuator unit are bonded together using a fusible film, thermally expanded air is released into the recess to thereby reduce pressure. Further, by arranging the recess at a position confronting a pressure generating chamber, an air layer formed by the recess is allowed to function as a vibration shielding member.

摘要： A method of manufacturing an actuator including an ink pump section made by forming a spacer plate with a plurality of window portions formed therein, a closure plate stacked on one side of the spacer plate for covering the window portions and a connection plate stacked on the other side of the spacer plate for covering the above window portions. These plates are formed as laminated ceramic green sheets that are later fired to form an integrated body. A piezoelectric/electrostrictive operating section composed of electrodes and a piezoelectric/electrostrictive layer is then formed on the outer surface of the closure plate. Thereafter, the actuator is pasted to a holding adhesive film and the holding adhesive film is stripped from the actuator after subjecting the actuator to a given inspection, if necessary, or to cutting into a given shape, if necessary. Subsequently, the actuator is heat-treated. Then, onto this actuator, an ink nozzle member with a plurality of nozzle holes is stacked and joined. The ink jet print head has a strong adhesive joint between the actuator and the ink nozzle member and improved liquid resistance.
