Title: Ceramic composition
Inventor: MORI TORU
IPC: C04B35/00
Filed: 1991-01-31
Abstract: PURPOSE:To obtain the objective ceramic composition for layer-built ceramic capacitor by using a ternary composition having a composition falling within the hatched area of the figure and substituting the Pb<2+> ion with Sr<2+> ion and/or Ba<2+> ion at a prescribed ratio. CONSTITUTION:Starting raw materials consisting of PbO, WO2, MgO2, Nb2O5, ZnO, TiO2, SrCO3 and BaCO3 are compounded with each other at ratios to get a composition of formula [Pb(Mg1/2W1/2)O3]x@{9146/-28}PbTiO3]y[Pb(Zn1/3 Nb2/3)O-3]z (x+y+z=1) falling within the hatched area of the figure. The Pb<2+> ion is substituted with Sr<2+> ion and/or Ba<2+> ion at a substitution ratio of 0.01-30mol%. The obtained composition is mixed in wet state and calcined at 800-850 deg.C. The calcined product is crushed in wet state, filtered, dried and burned at 950-1050 deg.C to obtain the objective ceramic composition having high dielectric constant, small decrease of capacitance under application of DC bias and low dielectric loss and sinterable at a low temperature.

Abstract: PURPOSE:To express patterns having deepness easily and pattern by screen process printing making it unnecessary to have many plates and printing processes. CONSTITUTION:A cutting pattern 3 cut out a pattern shape on an under coat film 2 is printed by screen process and thermography. A number of lines 4 including parts having the pattern shape are printed by screen process and thermography on the cutting pattern 3.

Also, the lines 4 to be printed by screen process are colored with the same series of color as the cutting pattern 3 and the color is thicker than that of the cutting pattern 3, and widths thereof are varied partially. Differences in density occur in wide and narrow parts of the raised lines 4 so as to produce multicolor expression. Thus, the same effect as multicolor printing can be obtained by screen process printing with one color.

Abstract: PURPOSE: To reproduce a painted color with fidelity to a color intended on a computer. CONSTITUTION: A deformation beam split reflection factor on an external painted plate is measured by a deformation beam split measuring instrument (S1). A feature amount concerning deformation and a feature amount concerning wave length are extracted from the measured deformation beam split reflection factor (S2). By reproducing the original deformation beam split reflection factor while using the extracted feature amounts or by changing the extracted feature amounts, the material feeling or color of the external plate is changed and the deformation beam split reflection factor is reconstituted (S3). The image of a painting color is displayed by using the reconstituted deformation beam split reflection factor (S4). Thus, the color or material feeling can be easily controlled.
