  • Publication number: 20100072821
    Abstract: Operating speed as well as output accuracy of a D-A converter is enhanced. With a semiconductor device including unit current sources, and unit current source switches, plural current source elements constituting each of the unit current sources are disposed so as to be evenly dispersed, thereby reducing errors of the current source element, dependent on distance while the unit current source switches are concentratedly disposed in a small region, thereby mitigating delay in operation, attributable to parasitic capacitance. In addition, with the semiconductor device including R2R resistance ladders, the R2R resistance ladder is provided on the positive and the negative of each of the unit current source switches, and the respective R2R resistance ladders are shorted with each other at respective nodes on a unit current source switch-by-unit current source switch basis, are rendered identical in length, thereby cancelling out a nonlinearity error attributable to wiring parasitic resistance.

  • Publication number: 20090136479
    Abstract: The instant invention provides methods for the treatment and prevention of viral infection, e.g., HIV infection, based on the discovery that viral replication utilizes the ubiquitination pathway of the host cell to replicate. Specifically, the invention provides methods for the treatment and prevention of viral infection, e.g., HIV infection, by modulation of ISG15 conjugation and deconjugation, e.g., by modulation of the activity or expression of UBP43 or UBEL-1.

  • Publication number: 20090073819
    Abstract: A recording apparatus includes an acquiring unit for acquiring, from an optical disc, disc-state information including at least information of an optical disc type, information of a recording format, and information indicating whether the optical disc has already been finalized, a first determining unit for determining, based on the information of the optical disc type and the information of the recording format in the acquired information, whether the optical disc type and the recording format correspond to one of predetermined combinations, a second determining unit for determining, based on the result of determination by the first determining unit and the acquired information, whether the optical disc needs to be finalized, and a display control unit for controlling, when the second determining unit determines that the optical disc needs to be finalized, display of a message representing the need of the finalization.

  • Publication number: 20080123499
    Abstract: In an image-recording device using a disk-type recording medium generated under the DVD+RW standard, a disk information-acquisition unit 250 acquires information about a disk 49, a disk-determination unit 260 determines that the disk 49 is a subject disk that is of a DVD+RW type and that stores video data generated by using a DVD menu and/or still-image data recorded onto the disk, an additional recording-control unit 220 controls additional recording performed for the disk 49 according to a result of the determination performed by the disk-determination unit 260, and a message display-control unit 270 makes a display unit 280 show a confirmation message used for shifting to a mode relating to the pros and cons of performing the additional recording and/or a message adapted to confirm that the DVD menu and the video data are updated, so that a mismatch which may occur between the DVD menu and/or the video data, and recorded image data is reduced.

  • Publication number: 20050278596
    Abstract: Components are provided including: an expected-value generating circuit that generates, upon reception of an output signal directed from the interface unit to the internal processing circuit; an expected-value signal for detecting an error in the output signal, a comparing and determining circuit that compares the output signal and the expected-value signal to determine whether these signals match with each other; and an output processing circuit that retains the determination result of the comparing and determining circuit and performs a process for externally outputting the determination result. In the case where a test pattern, which is an M-series pseudo-random-number signal, is input from a pulse generator or the like to the I/F unit for testing, a circuit based on a logic of generation of such an M-series pseudo-random-number signal is provided in the expected-value generating circuit.
