Abstract: A combined cosmetic jar and applicator storage device consisting of a structural body which provides a pair of back-to-back shallow recesses for holding a cosmetic material and an applicator, respectively. Two removable covers are carried by the body, one to close each of the recesses. The cover for one recess has a portion which telescopes into and is retained by a cooperable portion of the body, and has another portion consisting of a hinged flap which can be swung between open and closed positions to provide quick access to the applicator. Enhanced ease of use, coupled with improved function and an aesthetically pleasing physical appearance, are thus realizeable.

Abstract: An electronic stabilizer having a variable frequency soft start circuit, said circuit having a secondary coil coupled to a drive transformer of the electronic stabilizer. In the initial period when power is connected, the secondary coil may supply an induced voltage to a capacitor to generate a forward voltage to connect primary transistor to allow an inductance element to parallel the secondary coil to reduce the total inductance. The operating frequency of an LC oscillating circuit of the stabilizer hence increases. Relatively, the energy obtainable by the fluorescent lamp is reduced. The soft start circuit is further provided with a discharge loop of a secondary transistor for discharging of the capacitor to ensure that soft starts may be achieved under any conditions.
