  • Patent number: 9945687
    Abstract: A travel route display device (1) includes a display unit (130), a topographical data storage unit (110b) that stores three-dimensional topographical data, a travel data storage unit (110c) that stores travel data relating to a travel route of a vehicle and a driving status of the vehicle on the travel route, and a control unit (120) that, when displaying the topographical data stored in the topographical data storage unit (110b) on the display unit (130), simultaneously displays, on the display unit (130), the travel route indicated by the travel data stored in the travel data storage unit (110c) in a display mode that corresponds to the driving status.
    Type: Grant

  • Patent number: 6543332
    Abstract: In this invention, an idea is adopted in which the pressure at a forward portion and a backward portion of valve device is steppingly dropped twice. The valve device of the present invention includes, on the axis of a spool 600, a first valve 710 located nearer an inlet port and a second valve 720 located nearer an outlet port. A throttling area made by the second valve 720 is larger than a throttling area made by the first valve 710. For example, of all the pressure difference equal to 120 kg/cm2 or more reauired at the forward and backward portions of the valve device, a portion in the range where the problem of an occurrence of a foreign noise is not encountered (for example, a portion ranging from 100 to 120 kg/cm2) is undertaken by the first valve 710, and the remaining portion ranging from 20 to 30 kg/cm2 is undertaken by the second valve 720.

A throttling area made by the second valve 720 is larger than a throttling area made by the first valve 710. For example, of all the pressure difference equal to 120 kg/cm.sup.2 or more required at the forward and backward portions of the valve device, a portion in the range where the problem of an occurrence of a foreign noise is not encountered (for example, a portion ranging from 100 to 120 kg/cm.sup.2) is undertaken by the first valve 710, and the remaining portion ranging from 20 to 30 kg/cm.sup.2 is undertaken by the second valve 720.
