摘要： A sensor element for detecting solid particles in a fluid includes: a detecting unit including a piezoelectric film consisting essentially of a ceramic material, a first electrode coated onto at least a portion of the outer surface of the piezoelectric film, and a second electrode coated onto at least a portion of the inner surface of the piezoelectric film; a vibrating portion consisting essentially of a second ceramic material, the detecting unit being placed on the vibrating portion so that the second electrode is coated onto at least a portion of the vibrating portion; and a fixing portion for fixing the vibrating portion so that the vibrating portion may vibrate. At least one of the detecting unit and the vibrating portion contacts with a solid particle in the fluid so that the piezoelectric film converts the vibration into an electric signal. A particle sensor includes the sensor element. The sensor element and the particle sensor are excellent in particle detection precision and durability at low cost.

摘要： A sensor device adapted to detect at least one of a particle and a bubble in a fluid, includes a fluid nozzle defining a center of fluid flow; and a plurality of sensor elements for converting an impact of one of a particle and a bubble into an electrical signal, wherein a first sensor element is arranged closer to the center of fluid flow than a second sensor element. The sensor device includes a number of diaphragm sensor elements each having a sufficiently small mass for responding to a collision with the particle, and an apparatus for converting a vibration of the diaphragm portion into an electrical signal so as to detect the vibration. The multiple elements are arranged in the fluid flow stream such that different size particles will preferentially strike different elements.

摘要： A display element includes: an actuator including a piezoelectric film having a pair of surfaces and a pair of electrodes coated onto at least a portion of each of a pair of respective surfaces of the piezoelectric film; a movable flexing portion, in contact with one of the pair of electrodes, to support the actuator; a fixed portion for holding the flexing portion so that the flexing portion can move; means, connected to the actuator, for transmitting a displacement of the actuator; and a plate for transmitting light, disposed closely to the displacement-transmitting means. In this display element, a voltage is applied into the actuator through the pair of electrodes so as to control a rest position and a displacement of the actuator as well as a contact and a separation between the displacement-transmitting means and the plate so that a light emission at a predetermined position in the plate is controlled. Alternatively, a display element may include a laminated piezoelectric body having a plurality of piezoelectric layers and a plurality of electrode layers, wherein the piezoelectric layers and the electric layers are laminated. A display apparatus includes a plurality of display elements. The display element and the display apparatus have quick response, consume little electric power, have a small size, and have high brightness of a screen. Further, a colored screen does not need to increase the number of picture elements in comparison with a monochrome screen.

摘要： A ceramic compact having a patterned conductor is obtained by coating the patterned conductor with a slurry and then by hardening the slurry. The slurry is prepared by mixing a thermosetting resin precursor, a ceramic powder, and a medium. In the ceramic compact, an isocyanate- or isothiocyanate-containing gelling agent and a hydroxyl-containing polymer are reacted and hardened to produce a thermosetting resin. The hydroxyl-containing polymer is preferably a butyral resin, an ethylcellulose-based resin, a polyethyleneglycol-based resin, or a polyether-based resin.

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.
