    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 piezoelectric/electrostrictive (P/E) device includes at least one actuator section secured to thin plate sections with an adhesive. The actuator section includes a multilayered member including at least three actuator films, each of which include a P/E layer and electrode films. One or more holes or recesses are formed in portions of the thin plate sections on which the P/E elements are formed. The electrode films contact upper and lower surfaces of respective P/E layers and alternately extend to opposite surfaces thereof. End surface electrodes electrically connect an electrode film that contacts one of the P/E layers and an electrode film that contacts another one of the P/E layers. The end surface electrodes are electrically connected to terminals which are provided on a surface of an outermost layer of the P/E layers, and which are separated from one another by a predetermined distance.

    摘要: A piezoelectric/electrostrictive device includes a pair of mutually opposing thin plate sections, a movable section, and a fixing section for supporting the thin plate sections and the movable section. Piezoelectric/electrostrictive elements are arranged on at least one thin plate section of the pair of thin plate sections. A hole is formed by both inner walls of the pair of thin plate sections, an inner wall of the movable section, and an inner wall of the fixing section. The piezoelectric/electrostrictive device has a mechanism for restricting amplitude of the thin plate sections. The mechanism includes a cavity portion formed in the inner wall of the movable section and a stopper member provided on the inner wall of the fixing section, wherein the forward end of the stopper member extends into the cavity portion.
