  • Patent number: 7925364
    Abstract: Provided is an audio reproduction device capable of immediately starting to reproduce audio data, particularly compressed audio data, from an arbitrary point in a forward or a backward direction at an arbitrary speed. In the case where data, to be reproduced, which is stored in a storage device is compressed data, the compressed data is temporarily stored in a RAM. Then, the stored compressed data is decoded by a decoder, thereby extracting a segment of PCM data. The segment of PCM data is supplied to a PCM data buffer formed in a RAM via a reproduction controlling microcomputer. Based on an operation of a rotational operation element, the PCM data stored in the PCM data buffer formed in the RAM is reproduced by a reproduction processing circuit, thereby reducing a rapid change in reproduction speed.

  • Patent number: 7676615
    Abstract: A content data storage apparatus that enables content data on a plurality of client apparatuses to be individually updated according to the preferences or the like of users. Content data on a memory card is stored in association with client content management information for managing the content data and client content identification information for identifying the content data in management units. When client content identification information stored on a memory card connected to an input/output unit matches any storage content identification information stored on a hard disk, a control unit updates the content data of the memory card based on content data included in management units identified by this storage content identification information.

  • Patent number: 6171030
    Abstract: A vehicular soil treating machine having a base carrier with a crawler type vehicle drive, an upper rotary body rotatably mounted on the base carrier, and an excavation means mounted on the upper rotary body and equipped with a soil excavating bucket. Provided on the base carrier is an elongated continuous soil processing trough having a predetermined length in the longitudinal direction of the base carrier and internally provided with a tumbling/mixing means for uniformly mixing additive soil improving material into sand and soil which is fed from the excavation means. A soil hopper is provided over one end of the continuous processing trough, and an additive feed means is located behind the soil hopper to feed additive soil improving material to the continuous processing trough.
