Patent number: 11173932Abstract: Provided is a monitoring system that can find abnormality in a device that supports a vehicle body of a railway vehicle during running at an early stage. The monitoring system for the railway vehicle includes a detector and a determiner. The detector detects a pressure A1 of a first air spring, a pressure A2 of a second air spring, a pressure A3 of a third air spring, and a pressure A4 of a fourth air spring of the railway vehicle during running. The first, second, third, and fourth air springs are respectively disposed on right front, left front, right rear, and left rear sides in a running direction of the railway vehicle.

Publication number: 20060022652Abstract: A regulator circuit is provided which suppresses a variation in output voltage upon occurrence of a variation in input voltage or output current without any increase in steady-state power consumption. The regulator circuit includes a detection circuit and an auxiliary circuit in addition to an error amplifier, an output transistor, a first resistor, a second resistor, and a reference voltage source. The error amplifier, the output transistor, the first resistor, and the second resistor form a typical linear regulator. The detection circuit includes a detecting capacitor, a first transistor, and a gain control resistor, which are serially connected between an input terminal and a ground terminal. A variation in input voltage leads to a change in potential at one end of the detecting capacitor with the input voltage. This causes a transient detecting current to flow, thereby allowing for detecting a voltage variation.Type: ApplicationFiled: July 27, 2005Publication date: February 2, 2006Inventors: Kazuhiko Nishimura, Hiroki Inoue, Noburhiro Nishikawa
