摘要： An electron emitter includes an emitter layer formed of a dielectric material, an upper electrode, and a lower electrode. A drive voltage is applied between the upper electrode and the lower electrode, for emitting electrons. The upper electrode is formed of scale-like conductive particles on the upper surface of the emitter layer and has a plurality of opening portions. The surfaces of overhanging portions of the opening portions that face the emitter layer are apart from the emitter layer. The overhanging portions each have such a cross-sectional shape as to be acutely pointed toward the inner edge of the opening portion, or the tip end of the overhanging portion, so that lines of electric force concentrate at the inner edge.

摘要： An actuator includes a fired ceramic substrate having a space opened downward, a first electrode formed on the upper surface of the fired ceramic substrate above the space, a piezoelectric/electrostrictive body formed on the first electrode so that the volume changes with input and output of electric power, and a second electrode formed on the piezoelectric/electrostrictive body. The piezoelectric/electrostrictive body is composed of Pb(Zr1-xTix)O3 or (Li, Na, K) (Nb, Ta)O3 as a main component and contains crystals oriented along the direction of an electric field. In the actuator, the degree of orientation of the piezoelectric/electrostrictive body can be increased regardless of the orientation of the substrate on which the piezoelectric/electrostrictive body is formed.

摘要： A plate-like polycrystalline particle is produced by forming inorganic particles into a self-supported, sheet-like shaped body with a predetermined thickness, firing the shaped body, and crushing and classifying the fired shaped body by passing through a mesh having openings with a predetermined size. The inorganic particles are composed of an oxide having a perovskite structure and grow into crystal grains with an isotropic and polyhedral shape. Since grain growth in the thickness direction is limited and grain growth in the surface direction of the sheet is promoted, it is possible to obtain crystal grains having a high aspect ratio and a high degree of orientation. Therefore, in the plate-like polycrystalline particle, in most parts, the number of crystal grains present in the thickness direction of the particle at any one point is one, and a high aspect ratio and a high degree of orientation are achieved.
