    摘要： The present invention discloses a WC--Co alloy in which substantially only the WC particles of a surface layer or components other than metals belonging to the iron group and only the WC particles are exposed, and (a) an average particle diameter of the WC particles of the surface layer is larger than that of the WC particles of the interior, and/or (b) a surface hardness is higher than that of the interior. The WC--Co alloy itself is Used as a stock for a cutting tool or an abrasion and sliding resistant tool, or the alloy is used as a substrate and a hard carbon-layer excellent in adhesive strength is coated on the surface of the matrix.

    摘要： A zoom lens mount assembly in which a zooming cam frame is moved along the optical axis while rotating therearound and respective movable frames supporting an optical system are driven by such rotation and movement of the cam frame to effect a desired zooming. In another aspect there is provided a focussing cam frame adapted to be moved along the optical axis and to drive a movable frame provided with a focussing optical system and a program lens shutter.
