Abstract: There is provided a device having a reading unit that reads TOC data and audio data sets from a compact disk, a conversion unit that transcodes the audio data sets read by the reading unit to generate transcoded audio data sets, and a generation unit that generates a file or file group including the TOC data read by the reading unit and the transcoded audio data sets generated by the conversion unit, the file or file group having order information specifying order of the transcoded audio data sets as originally recorded on the compact disk.

Abstract: An MPEG conversion system for converting digital video signals transferred from a digital video camera to a personal computer into MPEG data and saving into a data storage apparatus is disclosed. When an intermediate working area for the conversion is entirely occupied, the camera is stopped. After the position of the tape at this time is read and memorized, the tape is rewound to a prescribed position. When the working area has a vacancy, the camera is started and, when the tape exactly reaches the memorized position, the writing of the digital video signals into the working area is resumed. The digital video signals are then converted into MPEG data. Images of a high quality are produced without frame drops or excessive occupation of the disk space even when a low speed personal computer is used. MPEG data can be obtained automatically by leaving the apparatus standing without manipulation for a prescribed time.

Abstract: An apparatus for MPEG conversion which converts digital video signals transferred from a digital video camera to a personal computer into MPEG data and writes converted data into an apparatus for keeping data, wherein the transferred digital video signals are temporarily written into a working area or, when the conversion cannot keep up with the transfer of the digital video signals, a portion of the digital video signals which cannot be processed by a real-time conversion into MPEG data is written into the working area while the conversion is conducted, and the digital video signals written into the working area are converted into MPEG data and then written into the apparatus for keeping data, the apparatus for MPEG conversion comprising: means for stopping transfer of the digital video signals by sending a command to the digital video camera when a capacity of the working area is completely occupied and means for starting transfer of the digital video signals by sending a command to the digital video camera

Abstract: A geared electric motor is provided with an armature having an armature shaft supported within a motor yoke and a gear casing attached to said motor yoke by a radial ball bearing having an outer ring fixed to the gear casing and an inner ring fixed to the armature shaft of the armature using a stop ring and a push nut. A commutator is mounted on the armature shaft and a plurality of brushes carried by brush holders are in sliding engagement with the commutator. The brush holders are mounted on a brush holder base connected by elastic bushings to a brush holder base setting member which in turn is secured to the gear casing in engagement with the outer ring of the ball bearing to locate the outer ring in the gear casing.
