  • Patent number: 7357650
    Abstract: A bulging wall portion, which forms a connector accommodation portion by bulging outward from a side wall, is formed in a cover plate portion of a cover. The bulging wall portion has an overhead wall formed such that it rises from the cover plate portion. A sloping wall is formed on the overhead wall such that roughly the center in the width direction of the connector accommodation portion serves as a vertex and the sloping wall slopes in downward gradients from the vertex toward both ends in the width direction. Water that flows down over the cover plate portion is caught by the overhead wall and flows downward along the sloping wall. The water is guided to both side faces on the outer sides in the width direction of the connector accommodation portion, so that it is drained off while avoiding the opening portions of the second through fourth connectors.

  • Patent number: 6374162
    Abstract: An apparatus for controlling behavior of a vehicle has an ECU (2) which estimates behavior of a yaw rate of the vehicle using a first target yaw rate, a second target yaw rate and an actual yaw rate to control the behavior of the yaw rate. The ECU (2) completes the behavior control if a completion condition is achieved during over-steering control of the vehicle. The completion condition is any one of the following matters. The steering wheel is operated to increase the steering angle. The vehicle is running straight in a stable state. The deviation between the second target yaw rate and the actual yaw rate is stable in a region lower than a preset value. The estimative brake fluid pressure is approximately identical to the fluid pressure of the master cylinder. The slip angle is small. The absolute values of the first and second target yaw rates and the absolute value of the actual yaw rate are smaller and approximately resemble to one another.

  • Publication number: 20010048539
    Abstract: The invention relates to an optical transmission system having the structure of effectively suppressing variation in cumulative chromatic dispersion in an optical fiber transmission line from a transmitter to a receiver, thereby enabling large-capacity phototransmission. The optical transmission system according to the invention monitors variation of chromatic dispersion in the optical fiber transmission line and compensates for the variation of chromatic dispersion, thereby suppressing the variation of cumulative chromatic dispersion on the whole of the optical fiber transmission line. The variation of chromatic dispersion is calculated by monitoring temperature variation of the optical fiber transmission line or by letting monitor light propagate in a dummy fiber transmission line disposed in parallel to the optical fiber transmission line.
