Title: Device for restraining railroad crossing from rumbling at power failure
Inventor: IMANARI TAKAO
IPC: B61L1/18
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To stop unnecessary rumbling of a railroad crossing while securing safety at the time when electric power fails in only in a control system and to rumble the railroad crossing when a train travelling at low speed in emergency approaches the railroad crossing on a device to carry out feeding to the railroad crossing itself and feeding to the control system such as a train detector and an automatic train control device. SOLUTION: This device starts emergency stop motion of each train by first stopping feeding to an automatic train control device from a battery part 33 at the time when a second substation 85 fails electric power. After time required for emergency stop completion passes, feeding of electric power from 2T to a 4T train detector is stopped, and rumbling of a railroad crossing is stopped by forcibly exciting a DC relay 61 by making a power failure U motion recovery contact point 67 on the side of a motion contact point. In the meantime, the F5T, F6T train detectors work by an uninterruptive electric power source, and when the train arrives in the relative territory, the railroad crossing starts rumbling.

Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to decrease crosstalks of recording signals to regenerative signals by a simple method by arranging a recording signal pair on a perpendicular bisector of a straight line connecting the regenerative signal pair to each other when the recording signals and the regenerative signals are balance circuits. SOLUTION: The coated optical fibers a, b of the recording signal pair are arranged on the perpendicular bisector connecting the coated fibers A, B of the regenerative signal pair to each other. These signal pairs are so constituted that the points a, A, B and the points b, A, B respectively constitute isosceles triangles. The magnitude of the magnetic fields that the currents flowing in the coated optical fiber (a) and the coated optical fiber (b) impart to the respective coated optical fibers A, B of the signal pair on the reproduction side is respectively equal. Since the coated optical fibers a, b of the recording signal pairs are balance circuits, the currents flowing in the coated optical fibers a, b are the same in the magnitude and are different in the polarity.  And also, the magnetic fields to be applied to the coated optical fibers A, B are the differential component of the magnetic fields by the coated optical fiber (a) and the coated optical fiber (b) and are diminished. In addition, since the coated optical fibers A, B of the regenerative signal pair are the balance circuits the influence thereof is further the differential-component and is drastically reduced. The crosstalks of the recording signals to the regenerative signals can be decreased.

Abstract: PROBLEM TO BE SOLVED: To realize a duplex controller which is capable of evading the whole system down as much as possible even when a standby side fails and can not be switched to a service side when the standby side is going to switch to the service side. SOLUTION: In the duplex controller in which each of duplex control circuits 11 and 21 is provided on the both of duplex devices, and the one of the devices is set to a service side and the other is set to a standby side according to the switch request signals that these duplex control circuits 11 and 21 output, a RS flip flop 3 is provided, and each of control means 12 and 22 and latches 13 and 23 are provided on the duplex control circuits 11 and 12.

Based on the output of the RS flip flop 3 imparted to the control means themselves, whether the switches are normally performed or not is discriminated. When the switches are normally performed, the service side is made into the state that the side does not perform a control. When the switches are not normally performed, the service side is made to continue the service state and the timing when the switches are normally performed is monitored.
