The present invention relates to a container for purifying water by utilization of sunlight, comprising a first surface that is formed of a permeable layer for sunlight and a second surface that is formed of an absorbing layer for sunlight. The circuit arrangement includes a flyback converter coupled between an input for receiving a rectified alternating line voltage and an output providing power for at least one LED device. The rotary switch is connected at one end to the other end of the stalk. MACCP66 was described in the present invention. The bit lines include main bit lines and sub bit lines to have a hierarchical structure, the main bit lines are divided among a plurality of interconnection layers, and a distance between the main bit lines in one of the interconnection layers is larger than a distance between the sub bit lines. Oxygen atoms are diffused into the Ti alloy to form an oxygen diffusion layer of TiO solid solution, thereby increasing wear resistance of the valve.
