Title: Pattern-correcting device
Inventor: KOIZUMI YASUHIRO
IPC: G03F1/00
Filed: 1979-04-20
Abstract: PURPOSE:To identify and correct minute defects and foreign objects highly efficiently, by emitting the light which is directed to a substrate on which a pattern is formed, and utilizing the signal obtained by sensing the light reflected from the illuminated portion. CONSTITUTION:A light source 4 emits a low-power beam 3 from the side of a Cr film, against the photomask on a substrate 1 on which a pattern 2 comprising a Cr film is formed. A light source 6 is arranged to emit a correcting laser beam 5 to the same position illuminated by the beam 3 at the back side of the substrate 1. Photosensors 7 are arranged at the vicinity of the beam 3 so that they are directed toward the illuminated portion. The outputs of the photosensors 7 control 8 the operation of the light source 6 for the correcting laser. If the beam 3 illuminates a defect 9, the output of an OR gate OG is a zero. If a foreign object 10 is illuminated, scattered lights enter the photosensor 7, and the output of the gate OG becomes a 1. Thus, the defects and foreign objects can be identified, the light source 6 is operated depending on the output of the OR gate, thereby the defects are automatically corrected and the number of the foreign objects can be counted.

Title: Script aligning device
Inventor: ITOU YOSHIO
IPC: B65H11/00
Filed: 1979-04-20
Abstract: PURPOSE: To convey thin script shees without causing crumples or bends, by introducing the sheets with a freely driven ball in the direction to be aligned, the ball being kept adequately slipping.  
     CONSTITUTION: When a script 14 is delivered skew to between a ball 8 and a weight plate 6, the ball 8 above a pinch roller 7 turns, as if having a shaft parallel to the center shaft of the roller 7, to carry the script 14 in the arrow direction until the right side of the script's tip hits a guide face 5, which causes a drag between them. The component of force produced by the drag and the thrust of script 14 makes the script 14 advanced while turning counterclockwise round the point of contact with the ball 8. Since the ball 8 giving a drive to the script 14 has no rotational shaft with minimum contact, the script 14, regardless of its thickness, slips between the ball 8 and plate 6 and is carried without deformation.
