  • Patent number: 9937862
    Abstract: A door mirror device includes a mirror housing mounted to a mirror base, a folding mechanism for enabling the mirror housing to pivot rearward of the vehicle when a load higher than a predetermined value is applied to the mirror housing from the front side of the vehicle. The mirror housing has a first region occupying more than half of the vertical area of the mirror housing and has a second region occupying a less area than the first region. The outer surface of the second region is located in front of the outer surface of the first region. The acute angle in a plan view between the outer surface of the second region and an outer side surface of the vehicle is greater than the acute angle between the outer surface of the first region and the outer side surface of the vehicle.

  • Patent number: 5579037
    Abstract: A method and system is provided wherein the information displayed in a predetermined area containing the predetermined position on the screen corresponding to the plane position of the point of a substantially pen-shaped pointing means is displayed in an enlarged form on said display means when the distance between the point of said pointing means and the screen of said display means is less than or equal to a first predetermined value and greater than a second predetermined value, where said second value is smaller than said first predetermined value. The state where the information which was displayed in said predetermined area is displayed in an enlarged form is maintained regardless of the change of the plane position of the point of said pointing means while said distance becomes said second predetermined value or smaller.
