摘要： A method of producing a dielectric layer made of a polycrystalline dielectric material having anisotropy in the coefficient of thermal expansion is provided, including the steps of providing a raw material powder, and heat treating the raw material powder at least to a temperature sufficient to cause a phase change from a first crystal orientation at room temperature to a different crystal orientation to provide an aggregate of oriented raw material particles having the same chemical composition as the raw material powder but having the different crystal orientation. The method also includes a step of forming a compact from the aggregate of oriented raw material particles, including a step of applying a shearing force to the aggregate and firing the compact to form the dielectric layer.

摘要： Heat-treating niobium pentoxide powder causes the powder to become agglutinated and bonded while phase transformation from an orthorhombic crystal to a monoclinic crystal occurs and resultantly bar-shaped c-axis-oriented niobium pentoxide particles, the longitudinal direction of which is identical to the c axis direction, are formed. A slurry is produced by mixing the c-axis-oriented niobium pentioxide particles with lithium carbonate and a binder and is molded as a tape by a doctor blade method to form a sheet-shaped compact. By so doing, bar-shaped or columnar c-axis oriented niobium pentoxide particles are aligned in the direction of forming the tape and in the meantime a compact filled with lithium carbonate is produced. By heating the compact, a dielectric layer including a c-axis-oriented lithium niobate polycrystalline material is produced.

摘要： One image is displayed in a period as one frame, which includes one charge accumulation period and one light emission period. In the charge accumulation period, all electron emitters are scanned, and voltages depending on the luminance levels of corresponding pixels are applied to the electron emitters which correspond to pixels to be turned on (to emit light), to accumulate charges (electrons) in amounts depending on the luminance levels of corresponding pixels in the electron emitters which correspond to pixels to be turned on. In the next light emission period, a constant voltage is applied to all the electron emitters to emit electrons in amounts depending on the luminance levels of corresponding pixels from the electron emitters which correspond to pixels to be turned on, thereby emitting light from the pixels to be turned on.
