  • Patent number: 11173932
    Abstract: 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. The determiner determines abnormality from a relation between a magnitude of diagonal imbalance P obtained from a formula (1) or (2) below and a mileage or elapsed time of the railway vehicle.

  • Publication number: 20060022652
    Abstract: 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.

  • Patent number: 6854709
    Abstract: Throttles (10) include a bore (1b) defined within throttle body (1a). A longitudinal axis defined within the bore serves as a throttle air flow channel. Throttle shaft (3) extends across the air flow channel and is rotatably supported by the throttle body about a rotational axis. Throttle valve (5) is coupled to the throttle shaft and opens and closes the air flow channel by rotating throttle shaft and throttle valve within the bore. The throttle valve extends perpendicularly to the longitudinal axis of the bore when the throttle valve is disposed in a fully closed position. Clearance (S) is defined between a peripheral edge (5a) of throttle valve and an inner wall of the bore when the throttle valve is in the fully closed position. The peripheral edge of the throttle valve end defines a substantially spherical surface having a radius (R) of curvature with respect to the rotational axis.

  • Patent number: 6829743
    Abstract: Supplier-specific data of material items are extracted from data of various material items used for the manufacture of a product. Tabular data having a structure that allows various pieces of environment consideration condition information about the extracted data to be input is created by using general-purpose spreadsheet software. The tabular data is laid out to locate an item whose contents are likely to change at an end of a table so as to minimize a change in data structure in the event of a change in contents of environment consideration condition items. The tabular data is provided to the supplier. Environment consideration condition information about each material item is acquired by using the tabular data containing the environment consideration condition information added to the tabular data on the supplier side.
