  • Rear view mirror locking mechanism
    Patent number: 4441682
    Abstract: A rear-view-mirror locking mechanism for a car comprises a longitudinal arm for holding the mirror and a U-shaped supporting bar coupled with said longitudinal arm through a locking screw and two spacing plates thereof. By turning the screw to abut tightly against the surface of the longitudinal arm, the supporting bar and the longitudinal arm are locked in a fixed position, secured at the fender of the car thus holding the mirror firmly.

  • Method of forming wide, deep dielectric filled isolation trenches in the surface of a silicon semiconductor substrate
    Patent number: 4385975
    Abstract: A method of forming a wide deep dielectric filled isolation trench in the surface of a silicon semiconductor substrate by forming a wide plug of chemical vapor deposited silicon dioxide in the trench, filling the remaining unfilled trench portions by chemical vapor depositing a layer of silicon dioxide over the substrate and etching back this layer. The method produces chemically pure, planar wide deep dielectric filled isolation trenches and may also be used to simultaneously produce narrow deep dielectric filled isolation trenches.
