Title: Silicon semiconductor substrate
Inventor: TANNO YUKINOBU
IPC: H01L21/205
Filed: 1985-02-21
Abstract: PURPOSE:To realize a silicon gettering substrate free of foreign matters or of grain generation by a method wherein a polycrystalline silicon film is deposited on the substrate rear surface whose distortion has been created by etching by means of spattering using an inert gas. CONSTITUTION:One side of a silicon substrate 1is subjected to etching accomplished by means of an argon spattering unit. This treatment results in the formation of a distorted layer 2 with the surface rough on said side of the silicon substrate 1. Next, the silicon substrate 1 is treated by a CVD unit of the normal pressure type or vacuum type, when a 0.5-mum-thick polycrystalline film 3 is grown at approximately 650 deg.C. The polycrystalline film 3 contributes to the formation of a field of distortion due to particle-to-particle boundaries and to the prevention of the distorted layer 2 form being annealed due to spattering.

Title: Color discrimination system
Inventor: YOSHIDA SHIGERU
IPC: G06T7/00
Filed: 1989-02-14
Abstract: PURPOSE:To reduce the capacity of a memory required for color discrimination by inputting the color signal of a color document, outputting an area number of the plane division of a color space from two components among input color components and a section number of the division from the remaining one component, and indexing a color specification area from the area number and section number and discriminating the color. CONSTITUTION:The color signal of the color document is inputted to output the area number of the plane division of the color space from the two components among the input color components and the section number of the division from the remaining one component, and the corresponding color specification area is calculated from the area number and section number to discriminate the color. Namely, line division and two-dimensional division are both used to improve the accuracy of the color space division and the specification area is approximated in combination with a linear divided section of B. When an area is specified in a two-dimensional space of RG, the shape of the two-dimensional area is optional, to the number of colors to be discriminated can be increased. Thus, the color space is divided into the linear and two-dimensional areas, whose section numbers and area numbers are found respectively to perform the color discrimination, thereby reducing the capacity of the memory required for the color discrimination.
