A multiple drapery rod supporting structure, comprising mounting brackets having cantilevered posts extending from the wall, and rod mounting clips which have extending tongue portions which are engaged within the ends of the rod to provide support and have a clip portion which easily snaps onto the support mounting posts. The content-based network system includes a plurality of user terminals, a plurality of access points, a plurality of content origin servers, and a transmission control device. The switching module is configured to alternately connect a capacitance across the first cell and the second cell at a switching frequency when a difference in the output voltages is greater than or equal to a first threshold. A coupling 16 is connected to the inner periphery of the internal gear 10 through helical splines 10d and 16a for purpose of power transmission.
