Abstract: PROBLEM TO BE SOLVED: To improve the brightness and light emitting efficiency and enlarge the lighting control range to a low electric current region by constantly controlling a low electric current value at a specified ratio or higher to high electric current value obtained by heightening the electric current quantity of high frequency electric current by a duty lighting control means.

Abstract: PURPOSE:To reproduce a black color and to well keep the quality of a black line image part in a color image, by applying a developing cycle for halftone reproduction for a halftone image area in a color original, and applying a monochrome developing cycle of black color only for the black line image area. CONSTITUTION:When the optical information of an original M from an exposure system A is made incident on a color separation means D, a color separation signal is outputted from the color separation means D, and a black line image area identifying means E discriminates the black line image area based on the color separation signal. A driving control means G erases the black line area out of latent images on a photosensitive body when the developing cycle for the halftone reproduction is applied, and adversely, when the developing cycle for the black color reproduction is applied, it erases a part other than the black line image area out of the latent images on the photosensitive body K. Afterwards, a latent image area corresponding to the halftone image area of the original M is developed by a halftone reproduction developing means B, and the latent image area corresponding to the black line image area of the original M is developed by a black color reproduction developing means C. In such way, it is possible to reproduce a black color area on the original in an optimum state.

Title: Method for improving surface roughness of silicon wafer and silicon wafer having improved surface roughness
Inventor: KOBAYASHI NORIHIRO
IPC: C30B29/06
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To improve both micro-roughness and haze level of a silicon wafer at the same time by heat treating of a mirror finished silicon wafer in oxidative atmosphere to form a thermal oxide film of specified thickness on the surface thereof and then removing the thermal oxide film. SOLUTION: A mirror finished silicon wafer is heat treated in oxidizing atmosphere to form a thermal oxide film of 300 nm thick or above on the surface thereof, and then the thermal oxide film is removed thus improving the surface roughness of the silicon wafer. Heat treatment in oxidizing atmosphere is suitably conducted at a relatively high temperature of 1,100-1,300 deg.C in order to improve the haze level, while shortening the oxidation time. The thermal oxide film is suitably removed by etching the silicon wafer using an aqueous solution containing hydrofluoric acid, in order to remove the thermal oxide film easily at low cost. In this case, an aqueous solution having HF concentration of 10% or less is suitably employed.
