    • PROBLEM TO BE SOLVED: To provide a method and an apparatus which can measure the bounce of a pantograph from a wire day and night in simple constitution. SOLUTION: The apparatus 1 for measuring the bounce of the pantograph 67 is equipped with an ultraviolet ray transmitting lens 11 which collects arc beams SL generated between a trolley wire 65 and the pantograph 67, and a photoelectric transducer 13 which receives the collected arc beams and converts them into an electric signal. The element photoelectrically converts only the ultraviolet ray. Hereby, the measuring apparatus can accurately measure the bounce of the pantographs in all vehicles running on a railway track, even if it is installed on the ground apart from the railway track where the vehicles run. Furthermore, the measuring apparatus can eliminate the influence of sunlight, and it can measure the bounce of the pantograph around the clock. COPYRIGHT: (C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a distance pulse correcting device which can reduce a mistake of measuring a distance by a compact device and to provide a running distance measuring apparatus.
      SOLUTION: When a speed generator for a vehicle generates a distance pulse in response to a rotation of a wheel, this pulse is input to a distance pulse input unit 5, and an acceleration calculating unit 6b calculates an acceleration a
      i based on this pulse. When the wheel slips or slides, the pulse output from the generator becomes abnormal. An acceleration deciding unit 7a decides whether the acceleration a
      i is abnormal or not, and detects the wheel's slip or slide. If the acceleration a
      i is abnormal, a pulse generator 8 generates a normal distance pulse based on the pulse output from the unit 5. As a result, the normal pulse is generated instead of the abnormal pulse generated at the wheel idle or slide time, and hence the mistake of measuring the distance or speed can be reduced as much as possible.
