Abstract: To provide a current detecting device capable of reducing lowering of responsiveness and variations in responsiveness among the phases. The current detecting device includes a plurality of bus bars that extend in the same direction and parallel to one another and are disposed at fixed intervals in the width direction of the bus bars, a plurality of current sensors disposed corresponding to the plurality of bus bars respectively, and a plurality of output terminals disposed corresponding to the plurality of bus bars respectively and wherein each output terminal is connected to one of the plurality of current sensors wherein the plurality of output terminals are disposed so that the distances between each of the output terminals and the corresponding bus bar are substantially constant.

Abstract: Disclosed is a method for mass-producing 4?-ethynyl d4T (4?-ethynyl-2?,3?-didehydro-3?-deoxythymidine) by a simpler process at low cost. Specifically disclosed is a method for producing 4?-ethynyl d4T, which is characterized by comprising a step for introducing a triple bond-containing group into a furfuryl alcohol derivative or a levoglucosenone, by reacting the furfuryl alcohol derivative or levoglucosenone with a certain compound, and a step for reacting a compound represented by the formula (III), which is obtained by the aforementioned step, with thymine.

Abstract: An optical disk device includes a reproduction component, an output component and a control component. The reproduction component directs a laser beam at an optical disk that is loaded in the optical disk device with the optical disk storing a plurality of audio data streams in a plurality of different acoustic qualities. The reproduction component reproduces one of the audio data streams. The output component outputs the one of the audio data streams to an amplifier. The control component acquires from the amplifier first audio format information indicating audio formats to which the amplifier corresponds, and acquires from the reproduction component second audio format information indicating audio formats of the audio data streams stored in the optical disk. The control component determines the one of the audio data streams with an audio format that belongs to both the first audio format information and the second audio format information.

Abstract: In an optical disk reproducing device for reproducing the video/audio information recorded on an optical disk wherein a setup menu is displayed for setting various kinds of functions of the optical disk reproducing device and a function is selected from the displayed setup menu, assuming that an instantaneous reproduction has been selected by the selecting means, when the optical disk is loaded in the optical disk reproducing device to reproduce the video/audio information, without an opening screen and a menu screen set for the optical disk being displayed, the video/audio information is reproduced from a first chapter included in a first title of the video/audio information recorded on the optical disk.

Abstract: A disk reproducing apparatus that includes: an acquisition unit that acquires predetermined information recorded on an optical disk; a determination unit that determines whether or not the predetermined information has speaker information; a first audio output unit that, when the predetermined information has the speaker information, outputs the audio signal based on the speaker information; a display unit that, when the predetermined information has no speaker information, displays a user setting screen for setting a number of audio signal output channels; a setting unit that selects an output channel on the user setting screen and sets a number of audio signal output channels; and a second audio output unit that outputs the audio signal based on the setting of the number of output channels set by the setting unit.

Abstract: If a media display key is depressed while the player stops the operation, playable media information is read from a flash ROM by a first media display processing unit and displayed on a display device. With the media display key being not depressed, if the optical disk is loaded, disk kind information is read out from the optical disk by a media determining unit. If it is determined by the media determining unit that the disk kind information read is not contained in the playable media information, the fact that the optical disk loaded is not playable is displayed on the display device by a playable/non-playable display processing unit. The playable media are displayed on the display device by a second display processing unit.
