摘要： A piezo-electric/electrostrictive film type chip (50) includes: a ceramic substrate (70) having a spacer plate (74) having a windows-disposed pattern (100) having a plurality of window portions (75) and a thin closure plate (72) for closing the window portions (75) which is unitarily connected with the spacer plate; and a piezo-electric/electrostrictive working portion (71) having a lower electrode (81), a piezo-electric/electrostrictive layer (82), and an upper electrode (83), each being formed in the form of a layer and laminated in this order at a closure portion of the window (75) on the outer surface of the closure plate (72) by a film formation method. A pin hole (52) for positioning is formed in or near the center of gravity of the windows-disposed pattern (100). Deterioration of positional preciseness of the pin hole and a through hole of the piezo-electric/electrostrictive actuator can be minimized, and the piezo-electric/electrostrictive actuator can be unitarily connected with an ink nozzle member with high positional preciseness.

摘要： An actuator unit for a laminated ink jet recording head includes: a first cover member for forming a vibrating member having piezoelectric vibrators on a surface thereof; a spacer for forming pressure generating chambers with a surface thereof sealed by the first cover member; a second cover member having ink jetting outlets and ink flowing inlets, each ink jetting outlet causing the corresponding pressure generating chamber to communicate with a corresponding nozzle opening of a flow path unit at one end of the pressure generating chamber, each ink flowing inlet causing the corresponding pressure generating chamber to communicate with a common ink chamber of the flow path unit at the other end of the pressure generating chamber. The actuator unit is prepared by laminating and fixing the first cover member, the spacer and the second cover member. A pitch at which the pressure generating chambers are arranged is set to a value equal to or smaller than a pitch at which the nozzle openings are arranged; widths of partition walls on outermost ends of pressure generating chambers located on the outermost ends are set to a value equal to or greater than a width of a partition wall defining adjacent pressure generating chambers and equal to or smaller than 1/2 of the nozzle opening arrangement pitch. An increase in the distance between the adjacent pressure generating chambers at the contact line between two actuator units is set to within a range of values substantially equal to the width of the partition wall.

摘要： An ink jet printer head includes a spacer including pressure generating chambers continuous to nozzle openings, ink supply paths, and reservoirs, a cover member for covering the pressure generating chambers in a sealing fashion, and pressure generating means for generating pressure in the pressure generating chambers in accordance with print data. In processing a silicon single-crystal substrate vertically oriented in (110) by anisotropic etching process, one of the walls of a path hole for forming a pressure generating chamber is aligned with one of the walls of a path hole for forming a reservoir. Walls defining the path hole for forming a pressure generating chamber, which are located in the vicinity of a nozzle opening, are connected to each other at an obtuse angle. As a result, the ink supply path serving as a narrow path for ink flow and the pressure generating chamber are formed as smooth flow paths. The walls in an area in the vicinity of the nozzle opening where ink tends to stay are substantially equally distanced from the nozzle opening. A smooth flow of ink is ensured.
