Filed: 1981-02-18
Abstract: PURPOSE:To enable a precise measurement by arranging one end of a plurality of transmission fibers vertical to the bottom surface of a prism while a plurality of receiving fibers are arranged in pairs with the transmission fibers on the side where incident light from the other end thereof reflects in refraction on the prism. CONSTITUTION:One end of a plurality of transmission fibers 4 is arranged at the right angle to the direction parallel to the edge line 38 on the bottom surface 32 of a prism 3 while the other end thereof is bundled so that light 7 enters a light emitting element 6. This light 7 is fully reflected at the projection point on the surface 3a of a prism 3 through the transmission fibers 4 and again, fully reflected at the projection point on the surface 3b opposite thereto. Receiving fibers 5 are arranged at the point where the light thus reflected arrives in such a manner as to be in pairs with the transmission fibers 4. Therefore, for example, when the projection points corresponding to the transmission fibers 44- 4n and the receiving fibers 54-5n thus paired are immersed in a liquid, the end of the receiving fibers 51-53 lights but the end of those 54-5n does not, thereby enabling the detection of the liquid level in a liquid vessel 1 depending on the light at the end of the receiving fibers 5.

Abstract: PURPOSE:To easily decides a subject part of a subject matter by applying the Fourier transformation to the picture data after adding and compressing them for each line and obtaining a power spectrum signal in case the picture data on the subject matter is static. CONSTITUTION:An image pickup means 10 is prepared to photograph a subject matter and to acquire the picture signals, together with an addition/compression means 11 which adds and compresses the picture data, a power spectrum calculation means 12 which calculates the power spectrum of the picture data, a deciding circuit 13 which compares the power spectrum signal with the reference value, and a data output means 14 which displays the deciding result of the circuit 13. The picture data are added together in the single direction via the means 11 in case the picture data are static. The added picture data undergo the Fourier transformation for calculation of the power spectrum. This calculated spectrum is compared with the reference value for recognition of pictures. Therefore the picture data are treated in a space frequency area. Thus it is possible to surely grasp a subject part even in such a case where no difference of density is substantially produced between the subject matter and the subject part.

Filed: 1983-02-16
Abstract: PURPOSE:To prevent a program from runaway by monitoring the execution period of a processor executing prescribed arithmetic processing, executing abnormal processing when a prescribed time exceeds, and when longer time than said time exceed, executing stop processing. CONSTITUTION:A monitoring timer 2' including two timers monitors the program execution period. The setting times t1, t2 of the two timers are set up to t1<t2. If the program execution period t0 exceeds t1, a time-up signal is inputted to a terminal IN1 of the processor 1 and the processor is stopped at its operation by software. When a timer reset signal is not inputted even after passing the prescribed time and t0>t2 is formed, a time up signal is inputted to a terminal IN2 of the processor 1 and the processor 1 is stopped at its operation by hardware. Thus, the program is prevented from runaway and system down is also prevented.
