IPC: H01L21/205
Filed: 1991-05-31
Abstract: PURPOSE:To reduce residual stress and dislocation density of a GaAs crystal layer in a GaAs/Si wafer having a structure wherein the GaAs crystal layer is laminated on an Si substrate.

IPC: H04N1/107
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of the image-omitted areas and to prevent occurrence of failures including the second reading of an original, etc., by detecting the overlapping degree of scan areas and notifying this overlapping degree. SOLUTION: A scanner main body 1 is moved zigzag on an original to read the original image, and an overlapping detection circuit detects every overlapping part of the read original image. Then the pixel data are connected together as a large sheet of image. Under such conditions, a notification means 4 consisting of an LED attached on a side face of the main body 1 notifies the overlapping state between a scan area and the scan area of the original image that is scanned in a reciprocating scan mode as the information on an overlapping degree (size) and also includes ten pilot lamps 4a consisting of the light emitting elements such as IEDs. Then the means 4 controls the number of lamps 4a which emit the light in response to the rate of overlapping scan area value set against the reading area of a certain reading position.
