    摘要: A colored frit prepared by fusing by heating a material composition comprising a devitrifying substance, a coloring agent and glass, and a method for manufacturing an artificial stone made by utilizing the colored frit. In the method of manufacturing artificial stones, the colored frits alone or a mixture of at least one kind of the colored frits and at least one kind of the colored frits and at least one kind of frits containing fluormicas are sintered, so that the colored frits are devitrified and the colors of the devitrified colored frits become distinctly visible to a viewer. This produces artificial stones having a wide variety of distinct colors and patterns.

    摘要: First and second semiconductor elements are formed in first and second semiconductor element forming regions which have the same thickness, include first and second semiconductor layers and are separated with dielectric isolation from each other. The thickness of the first semiconductor layer is made different between the first and second semiconductor element forming regions, so that the thickness of the second semiconductor layer becomes different between the first and second semiconductor element forming regions. Thus, the semiconductor device may have the semiconductor elements which have second semiconductor layers with different thicknesses in accordance with desired electrical characteristics for each of the semiconductor elements formed in the first and second semiconductor element forming regions, to complement a semiconductor device having the semiconductor elements each of which has independent optimum electrical characteristics.
