Cars detection device between distance of kiyariya

摘要

(57) Abstract (Modified) Objective Cars between the distance of the carrier regarding the curve correctlyThe ku offer the device in order to detect. Constitution As for cars detection device between distance, preparing for front part of carrierAnd others the searchlight 51 which projects the light ray of multiple provisions in re radial pattern and, counterThe morphism light ray the receptor on the rear section of the 51 which absorbs light and the aforementioned carrierIt had, it has possessed with the convex reflector 52 of circular arc condition.As for sensitivity of receptor 51 from cars between distance of desire of carrier, convexThe remaining distance which pulled the radius R2 of the circular face of surface reflector 52In equal distance R1 strength of light of the dot absorbing lightIn order for it to be possible, you adjust. It projected from the succeeding carrierAs for the light ray, the front with convex reflector 52 of the carrier run counterShining, it absorbs light in receptor 51. Circular arc curved line of radius R1With projects in the contact breaker points of the circular face of R2 only the light ray which reflected lightIt absorbs light as a belt. As for cars between distance of carrier, carrierRegardless of to the direction of the fellow, always (R1+R2) it is detected,ru.
