    摘要： A DC converter has a transformer with loosely coupled primary and secondary windings, a main switch connected in series with the primary winding of the transformer, and a series circuit connected to ends of one of the primary winding and main switch. The series circuit includes a clamp capacitor and an auxiliary switch. The main and auxiliary switches are alternately turned on/off so that a voltage of the secondary winding of the transformer is synchronously rectified with synchronous rectifiers and is smoothed with smoothing elements, to provide a DC output. The DC converter also includes a tertiary winding tightly coupled with the primary winding of the transformer, a voltage source to supply a voltage lower than a voltage generated by the tertiary winding of the transformer, and clamp diodes to clamp the voltage generated by the tertiary winding with the use of the voltage source. The clamp diodes provide voltage-clamped signals to drive the synchronous rectifiers.

    摘要： A seal useful in sealing slide out rooms used in recreational vehicles. The seal may be used singularly or in pairs to straddle a wall through which the opening is located. A bulb is attached to the base in a cantilevered manner over the base. The bulb has an outer arcuate portion that is integrally joined to opposing sidewall portions. The sidewall portions extend into an inner wall that defines an enclosed space within the bulb portion. The bulb portion may also have a protrusion that can touch the base. A wiper extends from the base substantially co-linearly to the base and opposite the offsetting member. A locating leg extending from the base is movable between a first position and a second position. The first position has the locating leg perpendicular to the base and the second position places the locating leg parallel to the base.
