Abstract: The present invention discloses a switching regulator and a control circuit thereof. The switching regulator includes a boost or buck-boost power stage, a first operation circuit and a bypass circuit. The power stage controls at least one power transistor switch included therein according to a first operation signal, to convert an input voltage to an output voltage at an output terminal. The first operation circuit generates the first operation signal in response to the output voltage or a related signal thereof. The bypass circuit includes a bypass transistor and a second operation circuit. When it is required to provide power to the output terminal promptly, the second operation circuit turns ON the bypass transistor, and when the input voltage is equal to the output voltage or equal to a sum of the output voltage plus a safety offset value, the second operation circuit turns OFF the bypass transistor.

Abstract: A ring binder mechanism has a housing and hinge plates supported for pivoting movement by the housing. The mechanism has rings, each including a first ring member mounted on a first hinge plate and a second ring member. The first ring member is movable relative to the second ring member between open and closed positions. The mechanism has a travel bar and a locking element that are free of fixed connection to the hinge plates and movable in translation relative to the housing and hinge plates. The travel bar blocks pivoting motion of the hinge plates when the ring members are closed. An elongate link connects a pivotable actuating lever to the travel bar such that pivoting motion of the actuating lever produces translational movement of the travel bar. The elongate link is oriented so it extends longitudinally relative to the housing.

Abstract: A ring mechanism comprises a housing, hinge plates, and ring members mounted on the hinge plates for retaining pages on the mechanism. An actuating lever is mounted on the housing for engaging the hinge plates and pivoting them to selectively move the ring members between an open position and a closed position. A travel bar is provided to block unintentional pivoting movement of the hinge plates when they are in the closed position. The lever pivots in a direction from one lateral side of the housing toward the other lateral side of the housing, i.e., about an axis that is oriented perpendicularly to the longitudinal axis of the housing and that extends upwardly relative to the housing. A ramped surface on the lever, e.g., a helical surface or a cam surface, engages the hinge plates to drive them to their open configuration.
