Abstract: A metallization or conductor or semiconductor layer formed over one major surface of a semiconductor wafer subjected to anodizing to form an anodized coating which has excellent adherence to the conductor or semiconductor layer and which is used as an etching mask when the conductor or semiconductor layer is etched.

Abstract: A steering mechanism for a vehicle comprising a first control member for operating a steering clutch and a steering brake on the left side of the vehicle, a second control member for operating a steering clutch and a steering brake on the right side of the vehicle, first link means connecting the first control member to the steering clutch and the steering brake on the left side, second link means connecting the second control member to the steering clutch and the steering brake on the right side, and a third control member and third link means connected thereto for simultaneously operating the left and right steering brakes. The first, second and third link means are made operative about vertical rod members to provide a flat compact mechanism. The third link means operates the steering brakes with a force increasing with the brake operating movement of the third control member to ensure effective braking action.
