The driving portion includes a pair of thin plate portions facing each other, and a film-like piezoelectric/electrostrictive element formed on at least a part of the outer surface of at least one of the thin plate portions. A ceramic green laminate including at least one ceramic green sheet constituting one of the thin plates and at least one ceramic green sheet having at least one hole formed thereon is formed. The ceramic green laminate is sintered to produce a ceramic laminate. A piezoelectric/electrostrictive element is formed by a film formation method on the outer surface of the thin plate portion of the ceramic laminate.

摘要： A piezoelectric/elecrostrictive device comprising a driving portion to be driven by a displacement of a piezoelectric/electrostrictive element, a movable portion to be operated based on a drive of the driving portion, and a fixing portion for holding the driving portion and the movable portion. The driving portion comprises a pair of thin plate portions facing each other, and a film-like piezoelectric/electrostrictive element including at least a pair of electrode films and a piezoelectric/electrostrictive film formed at least on the outer surface of at least one thin plate portion of the thin plate portions. The fixing portion is coupled with the movable portion via the driving portion, a hole is defined by an inner wall of the driving portion, an inner wall of the movable portion, and an inner wall of the fixing portion, and at least one side of a piezoelectric operating portion of said piezoelectric/electrostrictive element in a direction in which said thin plate portion connects with said fixing portion with the movable portion is structured to exist on the fixing portion or the movable portion. A ratio a/b of the thickness a of said hole and the width b of said thin plate portion is 0.5 to 20. Since the movable portion can be largely operated, the device can be used as a displacement element which is hardly affected by a harmful vibration in operation, and superior in mechanical strength, handling property, impact resistance, and humidity resistance, and a sensor element capable of detecting a vibration of the movable portion with fine precision.

The substrate has a distal end portion extending from a proximal portion by a predetermined distance from the proximal portion for contact with the electrically resistive layer. The distal end portion has a thickness smaller than that of the proximal portion, as measured in a direction perpendicular to a direction of extension of the distal end portion. At least one return circuit electrode formed from a metal or metal alloy sheet is provided on the other major surface of the substrate remote from the recording electrode(s).

摘要： A micropipette is provided including at least one substrate, an inlet port through which a sample is delivered from the outside, a cavity to be poured and filled with the sample, an introduction hole, and an injection port for expelling the sample are formed on the at least one substrate. The substrate for forming the cavity is made of ceramics, a piezoelectric/electrostrictive element is provided for at least one wall surface of the substrate, and the sample moves as a laminar flow in the cavity. The volume of the cavity is changed by driving the piezoelectric/electrostrictive element to expell a certain amount of the sample in the cavity from the injection port. According to the micropipette, it is possible to form microspots with high accuracy and high speed. According to a dispenser including the micropipette, it is possible to efficiently dispense hundreds to ten thousands of different samples at one time and form microspots. Therefore, productivity is remarkably improved.
