摘要： PROBLEM TO BE SOLVED: To provide a rolling stock traveling wheel inspecting device capable of accurately grasping the wear condition of wheels, high in device durability and reducing manual assistance and labor for the maintenance of the device. SOLUTION: This rolling stock traveling wheel inspecting device is provided with a first distance sensor installed outside of a rail and measuring the distance to an outer flange face of a wheel of a rolling stock in a contactless state to output the measured result; a second distance sensor installed inside the rail and measuring the distance to the inner back face of the wheel in a contactless state to output the measured result; and a processing part for computing the flange thickness of the wheel from the respective measured results of the first and second distance sensors and distance data related to the installation of the first and second distance sensors. The first and second distance sensors are respectively installed to measure the distances to the flange face and back face of the wheel from the front side in the traveling direction of the rolling stock, below the wheel tread of the rail.

摘要： PURPOSE:To attain registration of various reservation from an kind of telephone terminal set through the use of a general public telephone line. CONSTITUTION:This equipment is provided with a circuit changeover device 43 recognizing a type of a telephone terminal set of a caller, a voice response device 42 making communication in response to the type of the telephone terminal set being a caller based on a recognition result by the circuit changeover device 43, and a MODEM 44. As a result, when a telephone set 1 being an analog transmit a signal, the circuit changeover device 43 connects the voice response device 42 to the telephone set 1 and when a signal comes from a computer 2 with a telephone function being a digital equipment, the circuit changeover device 43 connects the computer 2 to the MODEM 44. Thus, a voice guidance or a screen display guidance is provided to a reservation application party via a telephone line 3 and the reservation is received simply at any time.

摘要： PURPOSE:To exactly grasp a wear state of a flange and contrive the improvement of its endurance and the reduction of hands and labor. CONSTITUTION:A first distance sensor 1a for measuring a distance L1 up to a flange outer face 10a is arranged on the outside of a rail 11, and a second distance sensor 1b for measuring another distance L2 up to the inner face 10b of a wheel is set on the inside of the rail 11 respectively. A means for calculating the thickness (d) of a flange 102 of the wheel 10 by using an expression of d=L0-(L1+L2) from a measurement result L1 of the first distance sensor 1a, another measurement result L2 of the second distance sensor 1b and the other distance L0 between the first distance sensor 1a and the second distance sensor 1b is provided. As the result, since the flange thickness (d) can be measured in a non-contact state, a wear state of the flange 102 can be grasped exactly, endurance of the device can be improved and hands and labor can be reduced.
