Abstract: When the brightness of an object is low, a sum output mode is set in causing a CCD to output pixel values accumulated therein. When the sum output mode is set, the CCD outputs the pixel values by adding up each odd number of pixel values distributed consecutively in a specified direction. As a result, a large signal component from which color information has not been lost completely can be obtained without increasing a noise component when the brightness is low. By reproducing the color information based on pixel sum values each obtained by adding up an odd number of pixel values in an overall controller, a proper color image can be obtained even if the brightness of the object is low.

Abstract: In single crystal SiC 1, growing single crystal SiC 3 is integrally formed on a surface of a single crystal hexagonal (6H type) &agr;-SiC substrate 2 used as a seed crystal. The number of micropipes 4A of the growing single crystal SiC 3 is less than that of the micropipes 4B of the single crystal &agr;-SiC substrate 2, and the thickness t3 thereof is less than the thickness t2 of the single crystal &agr;-SiC substrate 2, thereby making it possible to obtain the high quality-single crystal SiC wherein the number of the micropipes per unit area is less, thereby decreasing the distortion in the neighborhood of the micropipes. This can provide the high-quality single crystal SiC which can be practically used as a substrate wafer for fabricating a semiconductor device.

Abstract: Disclosed are a reversibly variable color pattering composition for synthetic resin articles which includes a granulated material containing (i) an olefin polymer and (ii) at least one reversibly variable color material selected from the group consisting of thermochromic materials and photochromic materials, the granulated material having been subjected to crosslinking reaction following granulation; a method of producing the same; and a shaped article having a reversibly variable color pattern as molded from a molding composition including a synthetic resin and the color patterning composition.

Abstract: Disclosed is a thermochromic color masterbatch for use in a thermoplastic resin comprising a wax having substantially homogeneously dispersed therein a thermochromic granular material which is coated with a hydrophilic high-molecular weight substance, said thermochromic granular material being a mixture of a thermochromic composition comprising an electron-donating chromogen, an electron acceptor and a solvent with a thermosetting resin.
