    摘要: A method for surface treatment is disclosed. The method is achieved by forming a MgO film on a metal surface through anode processing of Mg or Mg alloy in an alkaline solution. The alkaline solution includes a hydroxide, a thickening agent, and a film adjusting agent. As the method is performed, the target object is immersed in the alkaline solution, and the target object is connected to an anode with an average electric current density of 1˜5 A/dm, at a temperature of 0˜30° C., and within a time period of 10˜120 minutes to form a film of 5˜25 μm. The forming rate of the film of the method of the present invention is fast, and the formed film is of little stress.

    摘要: An umbrella frame having a pair of mounting rings and frame members which are pivotally connected to each other and to the mounting rings. A frame member having an elongated rod with a notch. A joint assembly is attached to the elongated rod and includes laterally opposed connector halves which mate to form a sleeve over the elongated rod. The sleeve has an inner boss which fits within the notch in the elongated rod when the connector halves are mated over the elongated rod. A collar slides around the mated connector halves to clamp the connector halves together over the elongated rod and to retain the inner boss within the notch in the elongated rod. Strut frame members have an end joint assembly at each end. Rib frame members have an end joint assembly at their inner ends and midpoint joint assemblies at rib midpoints. A mounting ring having a mounting base with a ring of spaced and vertically extending teeth. The frame members are received between the teeth. The teeth radially retain the frame members within the mounting base by engaging the frame member pivot lugs. A mounting cap has radially extending spaced teeth which fit between the teeth of the mounting base to retain the frame members within the mounting base. A lower mounting ring slides along the umbrella shaft to form an umbrella runner.
