  • Patent number: 8786247
    Abstract: A charging circuit receives electric power from a solar battery, and charges a secondary battery. A charging current detection unit generates a detection signal that corresponds to a charging current supplied from a DC/DC converter to the secondary battery. A control circuit generates a reference voltage that corresponds to the detection signal. A driving unit generates a pulse signal having a duty ratio that is adjusted such that the voltage output from the solar battery matches the reference voltage, and performs switching of a switching transistor according to the pulse signal. A control circuit adjusts the reference voltage such that the reference voltage becomes greater.

  • Publication number: 20140200366
    Abstract: The present invention provides a method for reducing accumulation of solid materials when manufacturing a (meth)acrylic acid ester having low biacetyl content (less than 2 ppm) by adding an aromatic diamine under conditions which provide sufficient residence time and thorough mixing to react up to 100% by weight of the biacetyl in the crude (meth)acrylic acid ester stream, prior to separation and purification. A feedback method is also provided for reducing solids accumulation in the separation and purification equipment of such processes by measuring the biacetyl content and adjusting the aromatic diamine addition rate so that excess aromatic diamine can be minimized. A third embodiment provides a method for reversing an accumulation of solid materials during such processes, while still producing a (meth)acrylic acid ester having low biacetyl content (less than 2 ppm), by reducing or ceasing the addition rate of aromatic diamine for a period of time.

    Abstract: The invention improves the voltage regulation rate of the switching regulator in lag control. A divided output voltage divided by the first resistor and the second resistor is input to a first polarity input terminal of a comparator. A driver is used for controlling a switching transistor and a synchronous rectified transistor according to an output pulse of the comparator. A feedback circuit is used for outputting a switching signal to the reverse input terminal of the comparator according to the output pulse, wherein the switching signal is used for switching two voltage levels between the input voltage and a ground voltage.
