Filed: 1987-04-17
Abstract: PURPOSE:To perform rapidly alignment of a plurality of directions and evaluation of the accuracy of alignment by putting the first pattern consisting of a plurality of unit figures which are arranged from two-dimensional point of view at prescribed intervals on top of the second pattern consisting of a plurality of unit figures which are arranged from two-dimensional point of view at intervals different from those of the first pattern, thereby comparing configurations of the above two patterns. CONSTITUTION:A quadrangle 2b which exists by being surrounded with the quadrangles 1 of the first pattern V1 is easily found out at a position which has distances as far as one line and two lines away from the central quadrangle 2a of the second pattern V2 respectively in the directions of X and Y by searching for one of the quadrangles 2 of the second pattern V2 which has the least overlap parts with a plurality of the quadrangles 1 of the first pattern V1. Thus, the second pattern V2 slips to the first pattern V1 in the negative directions of X and Y and it is easy to grasp the fact that the amounts of them are 1d and 2d respectively in the directions of X and Y. Thus, evaluation of the accuracy of alignment between upper and lower laminated thin films is rapidly performed.

Filed: 1984-05-10
Abstract: PURPOSE:To see a picture plane in a nutural state corresponding to human eyes and to accomplish long hours' use by controlling a viewing angle which a television camera views a subject in accordance with the viewing angle of a monitoring picture plane of a monitor television. CONSTITUTION:Respective output terminals of television cameras 10 and 11 are connected to a monitor television camera TV14 through a controller 13. The TV14 is provided with a distance measuring device 16, for instance, a ultrasonic sensor for measuring a distance (n) from a human body 15 in correspondence to a monitoring picture plane 17.
