Title: Electronic circuit for controlling automatic sorting integrated mechanism by measurement group
Inventor: KOBAYASHI SONOO
IPC: G01D1/14
Filed: 1980-08-28
Abstract: PURPOSE:To realize a practical automatic sorting system of simple constitution by fitting photosensors along the scale of a measuring instrument at optional positions on the scale surface and by obtaining control signals from sensor outputs. CONSTITUTION:At respective positions A, B and C on a scale surface, photosensors SA, SB and SC are fitted to output pulses by sending the momentary interception of luminous flux based upon the passing of a pointer. Those output pulses are inputted to FFS FA, FB and FC; Q=1 and Q'=0 at the 1st pulse and Q=0 and Q'=1 at the 2nd pulse. The output Q' is supplied to a low-priority AND circuit and the output Q, only when the output A' of a high-priority FF is a 1, is the output of the post-stage AND circuit. Therefore, when the pointer starts at the 0 point and stops at a point P indicating a measured value, only an output NB is a 1 and this is the control signal of a sorting mechanism.

Title: Contour compensation circuit
Inventor: YAGI YASUO
IPC: H04N5/208
Filed: 1989-05-10
Abstract: PURPOSE:To realize proper contour compensation by weakening the contour compensation to a dark part of a video signal and strengthening the contour compensation to a comparatively light part. CONSTITUTION:A nonlinear amplifier 3 acts on a low luminance component of a video signal so as to suppress the level and on a high luminance component to increase the level. Thus, when a video signal of high brightness is supplied to a contour compensation circuit, the contour compensation is much strengthened to the high brightness part with the nonlinear amplifier 3 and the video signal with emphasized contrast of the contour pact, is obtained. Moreover, when the video signal of a low brightness is supplied to the contour compensation circuit, the contour compensation is suppressed to the low brightness part with the nonlinear amplifier 3 to obtain a video signal whose contrast of the contour part is not emphasized. Thus, the contour compensation circuit is obtained to apply contour correction in response to the brightness level of the video signal.
