  • Patent number: 7787342
    Abstract: The present invention provides an information processing unit with improved operability. A reading section (10) reads information recorded in an optical disk, and outputs a read signal. A DSP (20) detects the read signal and processes to a reproducible form. A quick return button selects at least one of the processing details for starting or stopping the information processing and for changing a reproducing position of the information. When a reproducing state changing section (120) recognizes a change instruction for changing a processing state for the information, a reproduction control section (52) changes the processing state by the DSP 20 based on the processing details selected with the quick return button.

  • Publication number: 20090109668
    Abstract: After the LEDs 2 (red LEDs (R), green LEDs (G) and blue LEDs (B), or white LEDs (W)) are mounted on the frame 3, without dicing the frame 3 for dividing the LEDs 2 into pieces, the tie bar is punched off to form an electric circuit. Thus, the RGB three primary color LED light source 1A or the white LED light source 1B that emits light in the state of the frame 3 can be manufactured.

  • Patent number: 7476913
    Abstract: A light emitting device has a cup portion with a bottom surface opening, and one electrode of a light emitting element is connected to the cup portion. The other electrode of the light emitting element is connected to a lead set up from an inner space to outside the cup portion using the opening of the cup portion. Each electrode and lead of the light emitting device can be electrically connected without bonding wires. This prevents shadows or light unevenness from reflecting the shape of the bonding wire, thereby enhancing light-emission efficiency. As an alternative to setting up the lead from inside to the outside of the cup portion, the lead existing outside the cup portion and the other electrode are electrically connected via the bonding wire through the cup portion's opening. Thus, light outputted outside of the light emitting device is not intercepted by the bonding wire.

  • Patent number: 7394731
    Abstract: An information playback apparatus is provided to obtain editing effects using an optical disc in the same sense as an analog record disc is manipulated. An audio editing apparatus for playing back an optical disc such as a CD is provided with a rotatable jog dial, detecting device for detecting the amount of rotation of the jog dial, and sensing device for sensing the presence or absence of a pressing force on the jog dial. When the jog dial is rotated while being depressed with a predetermined pressing force, processing for providing sound effects is performed on the playback data to be played back from the optical disc in response to the amount of rotation detected by the detecting device. It is thereby possible to provide the same feeling of operation as provided by rotating an analog record disc through hand operations to produce playback sounds.

  • Publication number: 20060146659
    Abstract: A beat density detecting apparatus and an information playback apparatus are provided to detect distinctive characteristics that music or the like has and to provide the same as a novel information volume. Playback data read out from an information recording medium, such as an optical disc, and sub-code data containing the information of an elapsed track time indicating a recording position of the playback data are provided to a beat detecting unit and a beat position detecting unit, respectively. The beat detecting unit detects the number of occurrences of a change in amplitude at each predetermined frequency of the playback data, and the beat position detecting unit detects an elapsed track time from the sub-code data. Further, a beat density computing unit finds the number of occurrences with respect to the elapsed track time as the characteristics information of a beat density.
