Title: Video recording reproducing device
Inventor: YANO MITSUO
IPC: G11B20/02
Filed: 1991-02-04
Abstract: PURPOSE:To prevent malfunction of an AGC circuit by feeding back a voltage comparison circuit output to a gain control amplifier circuit so as to eliminate a pseudo synchronizing signal portion of a copy guard signal and extract only a horizontal synchronizing signal. CONSTITUTION:An input video signal is outputted through a gain control amplifier circuit 1 in an AGC circuit 101. Moreover, a negative pulse signal having a time width from the tail end ridge of a horizontal synchronizing signal till around a front edge of a succeeding horizontal synchronizing signal is generated by a horizontal synchronizing separation circuit 2 and an MM 3 and the horizontal synchronizing signal is gated to generate a keyed pulse and a signal superimposed with an output of the circuit 1 is peak-detected and the result is compared with a reference voltage level. The result of comparison is fed back to the circuit 1 and the circuit 1 adjusts the gain so that the detection voltage level and the reference voltage level are equal to each other. Then a pseudo synchronizing signal in existence in a copy guard signal added to the video signal is eliminated to avoid malfunction of the circuit 101.

Abstract: PROBLEM TO BE SOLVED: To obtain the suitable photometric information of a spot corresponding to a subject with memory capacity which is as small as possible based on picture element data by a range-finding sensor. SOLUTION: The image pickup area of either line image sensor 91 of the range-finding sensor consisting of a pair of line image sensors having a range- finding area in the center of a photographic image plane is divided into AF areas for range-finding AF1 to AF6 and AE areas for photometry AE1 to AE6 smaller than the AF area. Photometric information is operated for every AE area AE1 to AE6 by using picture element data outputted from the line image sensor 91, and the operated result is stored in a memory, then range-finding information is operated for every AF area AF1 to AF6 by using the picture element data. The AF area includes at least one AE area smaller in size than the AF area in the image pickup area so as to obtain the suitable photometric information of the spot corresponding to the AF area being a focusing object.

Title: Detector for initial opening of control valve
Inventor: KOGURE YOUICHIROU
IPC: F01D21/00
Filed: 1978-02-10
Abstract: PURPOSE: To prevent mulfunctioning of the detector by comparing the differential value of a signal for measuring an object to be controlled with the results from a comparator in combination of an arithmetic device for computing the head of the control valve deviated from the blind sector based on the signal and the comparator or the like for comparing the output signal and the detection signal.

The outputs of a differentiation circuit 36 for revolutions y of a turbine 5 and a device 37 for setting an allowable deviation ε 1  are fed to a comparator 38. When they are equal or the output of the differentiation circuit is larger than the other, a signal C is outputted. On the other hand, a deviation computing device 34 outputs a signal d when the deviation between the head values x 1  and x 2  becomes very large. A reset signal b is applied to an AND circuits 35 together with the signals c and d via a delay circuit 45 which outputs a circuit closing signal. With the command, a closing operation device 41 starts closing the control valve 2. The moment a comparator 39 indicates no deviation, a balance command e is sent to the controller 8.
