  • Publication number: 20120265428
    Abstract: According to the present invention, information which is associated with a motion of a vehicle can be acquired even in the case where no vehicle travels on a road. Motion information, which is associated with the motion of the vehicle on the road where the vehicle traveled, is acquired along with time information. Reference traffic information, which is traffic information on the road at a reference time which is specified by the time information, is acquired from a traffic information providing device which constantly provides the traffic information. A correlation between the motion information and the reference traffic information is specified.

  • Patent number: 6278232
    Abstract: A color cathode ray tube comprises a vacuum envelope in which there is mounted a shadow mask having a curved surface having a plurality of electron beam passing holes and a skirt extending downward from the margin of the curved surface. The shadow mask is supported by a mask frame having a substantially rectangular side wall. A shadow mask assembly constituted by fitting and securing the skirt into the side wall is set in the panel of the envelope, and the skirt is fitted and secured into the side wall by curving the middles of two or four facing sides of the skirt inward. Thereby, it is possible to provide a color cathode ray tube having the shadow mask assembly capable of obtaining a superior magnetic shielding characteristic by enlarging the effective region of the curved surface of the shadow mask.
