Title: Fault location estimating method, fault detecting method and its device in communication cable
Inventor: KUKIDA JUZO
IPC: H04B3/46
Filed: 1990-07-13
Abstract: PURPOSE:To estimate the fault location of a communication cable by sending a signal from the starting point of a communication line thereto and detecting the appearance of an unbalanced signal component between two core wires and earth of the communication line at the starting point resulting from the appearance of its reflection signal at the start point so as to measure the waveform. CONSTITUTION:A transmission signal is outputted to a communication line 4-5 from a transmission section 1 via a transformer 17. Moreover, a terminal of a reception section 2 is connected between a balanced neutral point of the transformer 17 and earth. If no fault is present on the communication line, since the two communication core wires are balanced with respect to earth, even when a signal is sent from the communication line 4-5, no signal is detected between a neutral point of the transformer and earth. However, when a local unbalance takes place due to a fault, a signal is detected between the neutral point of the transformer and earth depending on the degree of unbalance. When a pulse signal is used as the transmission signal, only a reflected pulse from the unbalanced point caused between both communication lines is detected as a received waveform (reflected pulse) 13 due to an insulation fault. Thus, the fault location is easily estimated from the propagation time of a rising point of the reflected pulse 13 (a time length in the vicinity of a time t2 to a time t1).

Title: Elastic sleeper support device, and elastic sleeper support structure using the device
Inventor: OKAMOTO TAKEAKI
IPC: E01D19/12
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce maintenance costs when a sleeper formed of an H beam is used relative to a wood sleeper, and to restrain levels of vibrations and noise when trains passes, by providing an elastic support device between a bridge girder and the H beam sleeper, and specifying a vertical spring constant. SOLUTION: The material and thickness of an elastic body 23 are adjusted to set a vertical spring constant to 98 MN/m or less. Therefore, an H beam sleeper is advantageous in strength in a section of a railroad bridge relative to a conventional wood sleeper, to thereby improve the durability and reduce maintenance costs. Further, an elastic body 23 of each of two elastic sleeper support devices A, A is vertically deformed to absorb vibrations, to exhibit vibration absorbing effect equal to or larger than the effect exhibited by the wood sleeper. In addition, horizontal relative movement of both plates 21, 22 is restricted by an engaged portion of each of plates 21, 22, which suppresses transverse deformation of the elastic body 23 to be generated when the train passes thereon.  Thus, vibrations and noise at the time of passage of the train can be reduced to levels equal to or less than those of the wood sleeper.
