Title: Ac deltai type failure selection method
Inventor: MOCHINAGA YOSHIFUMI
IPC: B60M3/00
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To open the circuit breaker by executing particular vector difference calculation between a failure current vector and an electric train load current vector to judge a failure if an amplitude of vector difference exceededs the predetermined value. SOLUTION: An AC ΔI type failure selection apparatus 1 converts, when a failure is generated, a feed current of an electric train 4 into a low voltage and small current and also calculates a difference between an input load current IL of electric train and a failure current IS in terms of vector. Failure selection is performed depending on this vector difference. That is, when an electric train load current vector is defined as [IL] and a failure current when a failure is generated as [IS], vector difference [ΔI] for failure detection is obtained from the expression, [ΔI]=[IS]-[IL ]. If a value of the vector difference [ΔI] has exceeded a value preset by the AC ΔI type failure selection apparatus 1, such event is selected as 'failure'. In this case, a protection output is output to a circuit breaker to open the circuit breaker.

Filed: 1988-10-06
Abstract: PURPOSE:To suppress level variation accompanying fine stop adjustments and to adjust a stop properly and automatically corresponding to a change in lighting condition by adjusting the stop according to the value obtained by integrating a digital signal in units of a specific number of frames. CONSTITUTION:An integrator 900 detects the start point and end point of the sampling of frames constituting one image plane from a video signal and integrates and outputs the value of the output digital signal of an analog/digital converting circuit 800 between the start point of the 1st frame among a specific number of frames and the end point of the final frame. Then an aperture value control circuit 200 outputs a signal for controlling the stop of the television camera 100 according to the output value of the integrator 900. Consequently, the stop need not be adjusted following up the level variation of a fine brightness signal to eliminate an adverse influence upon encoding. The stop is adjusted adaptively corresponding to the change in lighting condition, etc., to obtain an excellent image.
