  • Patent number: 8345365
    Abstract: A processing unit performs a method including controlling a reading-out of data from a first storage medium at a predetermined read-out data rate to produce inputted data, and controlling a compression of the inputted data to produce first compressed data of a first compressed format. The method includes controlling a storage of the first compressed data in a second storage medium at a faster writing data rate than the predetermined read-out data rate, controlling a reading-out of second compressed data of a second compressed format from the second storage medium, and controlling a decompression of the second compressed data to produce decompressed data. The method also includes controlling simultaneously the storage of the first compressed data in the second storage medium, the reading-out of the second compressed data from the second storage medium, and audibly reproducing the decompressed data. The first compressed format is different from the second compressed format.

  • Patent number: 8249516
    Abstract: An output signal SHS is secondarily amplified by a high-frequency amplifier AMP3 and an output signal SHR is secondarily amplified by an AMP4 for which high-frequency side amplitude reducing means is taken. In this case, the AMP4 has small gain of a high-frequency region and its output SHR-2 is reduced in amplitude. However, a high-frequency noise has a frequency higher than that of a carrier wave SH and the amplitude of a noise NzB becomes smaller. The other output signal SHS is directly amplified by the wideband amplifier AMP3. The width of an SHS-2 and the width of the SHR-2 are adjusted by amplitude adjusting means throughout the whole region and then mutually added by both signals addition amplifying means again so that the amplitude of the output signal SHS is adjusted to the SHR-2, and a predetermined threshold value is set to extract the noises.

  • Patent number: 8232830
    Abstract: A highly efficient rectifier can readily replace a two-terminal diode. Its conduction losses are reduced from that of the two-terminal diode. Connected between the source and drain of a MOSFET including a parasitic diode are a micro-power converter section for boosting a conduction voltage Vds between the source and drain to a predetermined voltage, and a self-drive control section that operates based on a voltage output from the micro-power converter section. When the source and drain are conductive with each other, the micro-power converter section generates, from the conduction voltage Vds, a power source voltage for the self-drive control section, and the self-drive control section (4) continues drive control of the MOSFET.

  • Publication number: 20120187863
    Abstract: A power supply circuit drives circuits having different numbers of series-connected LEDs without changing a circuit constant or a component. An LED series circuit is connected to a power converter circuit of a power supply circuit. The power converter circuit is controlled by a control arithmetic circuit, and supplies a constant current to the LED series circuit. A voltage detection circuit detects a voltage applied to the LED series circuit. The control arithmetic circuit checks whether the LED series circuit has 40 LEDs or 20 LEDs, based on the voltage detected by the voltage detection circuit. The control arithmetic circuit holds a constant-current value table for 40 LEDs and a constant-current value table for 20 LEDs. In accordance with the detected voltage, the control arithmetic circuit selects one constant-current value table, and controls the power converter circuit based on the constant-current value table selected.
