CONSTITUTION:From a reproducing video signal, an FM conversion low frequency video signal YLFM and a low frequency conversion high frequency video signal YHD are separated, by a BPF 19 and an LPF 20, respectively, the signal YLFM is demodulated to the original signal YL by an FM demodulating circuit 21, and a time base error is eliminated by a time base correcting circuit (TBC) 22. The signal YHD is converted to the original signal YH through a TBC 23, and a frequency converting circuit 33, collected to one system by an adding circuit 35, and outputted. From the signal YL, a pilot signal is extracted by a pilot extracting circuit 26, and by using a PLL 25, a sampling clock is sent to A/D converters 22-1, 23-1. On the other hand, a write signal generating circuit 24 generates address signals 29, 30 on a RAM for storing a sampling data, and sends them to RAMs 22-2, 23-2. Readout signal generating circuits 28-1, 28-2 control independently readout addresses of the RAMs 22-2, 23-2.

Title: Power feeder for electric rolling stock
Inventor: AISAKA TORU
IPC: B60L1/00
Filed: 1986-03-26
Abstract: PURPOSE:To minimize the interruption of power to a load due to wire separation, by establishing the output voltage of a power converter when the wires of a collector are reset after they are separated from, and by feeding the power to the load at the same time. CONSTITUTION:When the wire of a collector 4 is separated from during the working of power converters 1, 2, the working of the power converter 1 is stopped and the output voltage is set to be zero. Then, with the action of a voltage detector 12, a contact 12a breaks. Even if the contact 12a breaks, an excitation coil 17 is excited for TD2 hours with the action of an OFF delay timer 19 and a load contactor 8 is in a making state. When the wire is reset within TD2 hours after the wire is separated from, and the output voltage of the power converter 1 is established, the excitation coil 17 is continuously excited by the voltage detector 12. As a result, a time for the interruption of power to a load can be shortened.

In such a constitution of this image input device, a reflected light image is obtained as the difference between two times of photographing which are carried out in both emitting and non-emitting states of a light emitting part 7. A phase control part 2 changes the variation cycle and the photographing action of external light optionally or at a prescribed step. An external light effect evaluation means 9 is used to detect the optimum phase difference. The means 9 evaluates the degree of variation of the external light between two times of photographing against the current phase difference and decides the optimum phase difference based on the evaluation result.
