    • An audio data recording/reproduction system which is simple in configuration, convenient and safe to use, and an audio data recording medium therefor is to be provided. A music data recording medium is configured in which power information correlated to the average sound pressure power of audio data matching music pieces (music programs) is recorded, appended to each of the music pieces (music programs). In the audio data recording/reproduction system, its encoding unit is provided with a power information generating section which, receiving digital audio data matching a music piece (music program), generates power information correlated to the average sound pressure power of the audio data, and records in the recording unit the generated power information made relevant to compressed data resulting from the compression of the digital audio data; and its decoding unit extracts the power information, restores the original digital audio data from the compressed audio data, and outputs the data adjusted on the basis of the power information, or outputs the restored digital audio data and the power information.
    • 提供一种简单的结构,方便和安全使用的音频数据记录/再现系统及其音频数据记录介质。 配置音乐数据记录介质,其中记录与音乐片段(音乐节目)相匹配的音频数据的平均声压力相关的功率信息,附加到每个音乐片段(音乐节目)。 在音频数据记录/再现系统中,其编码单元设置有功率信息产生部分,其接收与音乐片段(音乐节目)匹配的数字音频数据,产生与音频数据的平均声压功率相关的功率信息, 并且在记录单元中记录与由数字音频数据的压缩产生的压缩数据相关的生成的功率信息; 并且其解码单元提取功率信息,从压缩音频数据恢复原始数字音频数据,并输出基于功率信息调整的数据,或者输出恢复的数字音频数据和功率信息。

    • A signal discriminator comprising:a plurality of sets of dual divided magnetic cores having different characteristics;a case made of a synthetic resin having a hinge capable of opening and closing the case and a latch means, of which inner portion is divided into sections by a plurality of partition plates, said sections respectively accommodating the plurality of sets of dual divided magnetic cores; andpress-contacting means interposed and retained between the case and the plurality of sets of dual divided magnetic cores, which press the plurality of sets of dual divided magnetic cores when the case is closed and latched by the latch means, thereby uniformly press-contacting respective divided faces of the plurality of sets of dual divided magnetic cores.
    • 一种信号鉴别器,包括:具有不同特性的多组双分割磁芯; 由具有能够打开和关闭壳体的铰链的合成树脂制成的壳体和其内部由多个分隔板分成多个部分的闩锁装置,所述部分分别容纳多组双分割磁芯 ; 以及夹持并保持在所述壳体与所述多个双分割磁芯组之间的按压接触装置,当所述壳体关闭并且通过所述闩锁装置锁定时,所述多个组合的双分割磁芯被按压,从而均匀地压接 所述多组双分割磁芯的各自的分割面。
