Title: Wafer positioning apparatus and method for returning wafer to original position
Inventor: SEDACHI MITSUO
IPC: H01L21/68
Filed: 1988-11-22
Abstract: PURPOSE:To make it possible to align the position of a wafer quickly and highly accurately by obtaining the operation of the theta axis of a table based on the inclination of a straight line passing two points of an orientation flat part and a deviation angle from the reference angle of the xytheta table. CONSTITUTION:A contour point P1 of a wafer which is closest to the center of gravity PG of the image pattern of a wafer is obtained from image data. The direction of a segment PG-P1 is made to be an approximate rotary angle alpha of the wafer. Windows W1, W2 and W3 are set in the vicinities of the intersections between three imaginary straight lines having the inclinations of +pi/2, -pi and -pi/2 with respect to the approximate rotary angle alpha and the contour of the wafer. The straight lines pass the center of gravity PG. The average contour points of the wafer are obtained in windows W1, W2 and W3. The amounts of deviations of the wafer in the directions (x) and (y) are obtained from the points. Of + or -pi/4 and + or -3pi/4, the direction closest to the final positioning direction (a) of the wafer is used, and the angular difference between the direction and the approximate rotary angle of the wafer is made to be the rotating amount of the wafer. Thus an xytheta table is rotated. Average contour points P5 and P6 in the windows which are set at the orientation flat part are obtained. The inclination of a straight line perpendicular to the straight line P5-P6 is made to be the rotary angle of the wafer. The angular difference between the angle and the final positioning direction of the wafer (a) is made to be a correcting amount theta for wafer rotation, and the axis thetaof the xytheta table is rotated.

Title: Concentration detecting device for color copying machine
Inventor: BISAIJI TAKASHI
IPC: G03G15/01
Filed: 1985-12-27
Abstract: PURPOSE:To detect the concentration of a color toner and a black toner with high accuracy by arranging a detecting light generating part and a detecting part which detects the concentration of a developing pattern by a light quantity which transmits the pattern holder facing each other. CONSTITUTION:In the case of detecting developing pattern 16 by a color toner, a detecting light 13 is reflected by the developing pattern 16 of high reflectance to become a reflected light 18. The light quantity detected by a detecting part 15 transmitting through a photosensitive body 10 is decreased, as the toner sticking quantity increases. In the case of detecting a developing pattern 17 by a black toner, the light quantity, which is obtained when the detecting light 13 is absorbed by the developing pattern 17 of low reflectance, passes through the photosensitive body 10 and detected by the detecting part 15, is decreased, as the toner sticking quantity increases. Namely, the black toner, same as the color toner, has a characteristic of 'toner sticking quantity-transmitted light quantity' which has a large S/N with respect to the reference value. Thus, either in the color toner or the black toner, the concentration can be detected with a high accuracy by an identical method through the use of the identical detector 15.
