Abstract: PURPOSE:To effectively utilize a light flux from a light source, to improve light converging efficiency and to uniformly illuminate a surface to be illuminated, by arranging at a part of light converging system a lens which mainly generates an introvert comatic aberration. CONSTITUTION:A light converging optical system 4 converges a light source image formed in the vicinity of the 2nd focus into a position in the vicinity of a field lens 5 and makes the image incident upon the left end face of an optical integrator 6 for forming many light fluxes with uniform light distributing characteristics. A meniscus-shaped lens 4A for mainly generating an introvert comatic aberration is arranged on a part of the optical system 4 so that the center of curvature of the lens surface is positioned in the 2nd focus direction where the light source image based upon an elliptic reflector 2 is formed. Consequently, peripheral light fluxes among illuminating light fluxes can be prevented from vignetting and utilized as illuminating light and the light converging efficiency can be improved.

Title: Priority discriminating circuit
Inventor: INOUE SAKAE

Filed: 1977-09-16
Abstract: PURPOSE: To enable a device low in priority to continue its process until the end even if a request signal from a device higher in priority arrives, and also to shorten the mean latency time by providing a control gate circuit.  
     CONSTITUTION: Request-to-use signals from respective devices are supplied to terminals 11, 12 and 13 according to priority. Then, AND circuit 51 and 52 interposed between, terminal 11 and FF31, and terminal 12 anf FF32, supplied with inversion signals of permit-to-use outputs of priorities lower than their priorities, are unable to receive request to use signals while permit-to-use outputs lower in priority are sent. Therefore, when permit-to-use signals are sent to, for example, terminal 23, circuits 51 and 52 become inhibited and are unable to receiver signals if arriving at terminals 11 and 12. In other words, the circuit can be obtained which will not interrupt the process of a device low in priority in its progress and waites until the process ends.
