摘要： A piezoelectric/electrostrictive device includes: a driving portion which is driven by displacement of a piezo-electric/electrostrictive element, a movable portion which operates on the basis of a drive of the driving portion, and a fixed portion for supporting the above driving portion and movable portion. It has a driving portion including thin plates facing each other and a thin film piezoelectric/electrostrictive element formed on the surface of at least one of the thin plates, and the above fixed portion and the above movable portion are joined by the driving portion. In this piezoelectric/electrostrictive element, the movable portion can largely be displaced, and it is not easily affected by a harmful vibration in operation, and it is excellent in mechanical strength, handling efficiency, impact resistance, and moisture resistance.

摘要： An axial-flow particle sensor has a sensor element and a housing. The outlet of fluid is placed at the opposite side of the inlet of the fluid, throughholes are formed at the circumference of the vibrating portion of the sensor element, and the vibrating portion of the sensor element is placed on the extension of the flow of the fluid so that the fluid entering from the inlet flows through the throughholes and flows out from the outlet. Two or more throughholes may be formed symmetrically with the axis. The throughhole may be formed on a ceramic substrate, or may be a gap between the ceramic substrate and the housing.

摘要： A recording head including at least one electrode, and a substrate structure for supporting each electrode. Each electrode and the substrate are held in contact with a recording medium or a planar intermediate member interposed between the recording medium and the recording head, so that an electric current is applied to the recording medium or the intermediate member. The substrate has a distal end portion extending from a proximal portion for contact with the recording medium and the intermediate member. The distal end portion has a constant thickness smaller than that of the proximal portion, as viewed in a direction perpendicular to a direction of extension of the end portion. The distal end portion is made of a material whose wear resistance is lower than that of the electrode.
