  • Patent number: 11970111
    Abstract: A vehicular exterior rearview mirror assembly includes a mounting arm and a mirror head at one end of the mounting arm distal from an attachment portion of the mounting arm that is configured for attachment at a vehicle. A mirror reflective element is fixedly attached at the mirror head. An innermost side of the mirror reflective element is attached at a front side of an attachment plate. The mirror reflective element moves in tandem with movement of the mirror head relative to the mounting arm when the driver of the vehicle operates an electrically-operable actuator. The attachment plate includes wall structure that extends from the front side of the attachment plate and circumscribes and spans the perimeter circumferential edge of the glass substrate and does not encroach onto and does not overlap the front surface of the glass substrate of the exterior mirror reflective element.

  • Patent number: 11970113
    Abstract: A vehicular vision system includes a forward-viewing camera located behind and viewing through a vehicle windshield, a rearward-viewing camera located at a rear of the vehicle, and a common image processor operable for processing captured image data. A video display screen is located within the interior cabin of the vehicle viewable by a driver of the vehicle. The common image processor processes first image data captured by the forward-viewing camera to detect at least one vehicle present exterior the equipped vehicle. Responsive to the vehicle being shifted into a reverse gear and while the driver is executing a reversing maneuver, video images derived from image data captured by at least the rearward-viewing camera are displayed by the video display screen.

  • Publication number: 20040253481
    Abstract: The magnetic recording medium includes a non-magnetic substrate having a front surface and a back surface. Coated on the front surface of the substrate is a lower support layer, or sub-layer, and at least one magnetic upper layer which together comprise the front coating. The magnetic upper layer contains a primary magnetic particulate pigment and a binder system therefor. The topmost magnetic upper layer is compressed, yielding a dense coating, with less than 14% porosity, and has a thickness of from about 0.02 micron to about 0.3 micron. The lower support layer comprises a nonmagnetic or soft magnetic pigment particle, and a binder system therefor. A back coating is formed on the back surface of the substrate. The magnetic medium of the invention has fewer than 400 tape dropouts per square inch at a 60% threshold, and fewer than 30 dropouts per square inch at a 40% threshold.

  • Publication number: 20040072029
    Abstract: A method for producing a magnetic recording medium includes applying a non-magnetic back coat to a substrate, applying a magnetic front coat to the substrate, in-line calendering the coated substrate using opposed rolls, at least one of the rolls being a generally compliant roll, and off-line calendering the substrate using opposed, generally non-compliant rolls. The off-line calendering optionally includes steel-on-steel calendering and the method optionally includes only one off-line calendering pass and only one in-line calendering pass. Calendering the coated substrate optionally occurs using at least one nip, the calendering including calendering the coated substrate through a final nip including generally non-compliant rolls. Other methods, and magnetic recording media produced by such methods, also are disclosed.

  • Patent number: 5628827
    Abstract: A coater incorporates a die, a reservoir, a gravure cylinder, and a doctor blade for applying coating fluid to a moving surface. The flow rate of coating fluid to the gravure cylinder is controlled to equal the rate at which coating fluid is consumed by the coating process. This eliminates the need to recycle surplus coating fluid. The coating fluid can be quickly and conveniently replaced with a solvent in the reservoir when coating is not being performed to reduce the occurrence of coating defects arising from excessive evaporation of solvent and premature solidification of coating fluid.
