    摘要: A driving apparatus and a driving method for a single phase motor utilizes a driving transistor unit, and an auxiliary driving transistor unit to provide two driving currents with the same direction as the single phase coil. Next, a control unit is used to control the conducting and shutting down of the driving transistor unit and the auxiliary driving transistor unit according to the location of the rotating device of the single phase motor. Thereby, the driving current on the single phase coil recirculates to reduce the vibration and noise of the single phase motor, and prevent the problem of the single phase motor not turning on.

    摘要: An AC signal producer comprises a controlling unit, a Class-D switch circuit, and a low-pass filter. The control unit receives a DC signal and produces a PWM control signal via checking reference tables. The Class-D switch circuit receives the PWM control signal and outputs a square-wave signal. The low-pass filter converts the square-wave signal into the AC signal. Thereby, disadvantages associated with the utilization of an oscillator and a transformer to convert the DC signal to an AC signal could be solved.

    摘要: An antitussive composition is provided. A pharmaceutical composition for relieving, preventing and/or treating a cough includes a sufficient amount of the Morus australis Poir extract as an active component. The effective Morus australis Poir extract is prepared by extracting the root-bark of the Morus australis Poir with water, ethanol, acetone, ethyl acetate, or a combination thereof. The crude extract can be further fractioned by ultrafiltration or reverse phase column.

    摘要: An AC signal producer comprises a controlling unit, a Class-D switch circuit, and a low-pass filter. The control unit receives a DC signal and produces a PWM control signal via checking reference tables. The Class-D switch circuit receives the PWM control signal and outputs a square-wave signal. The low-pass filter transforms the square-wave signal into the AC signal. Thereby, the defect of using an oscillator and a transformer to perform the DC to an AC function in the DC system is solved by the present invention.
