    • In a coin sorting device having a fundamental function for judging whether or not a deposited coin is included in a true-coin kind, an additional function is provided to judge about whether or not the deposited coin is included in a false-coln kind. The true-coln kind is represented by a first coin datum memorized in a first memory part (27). The false-coin kind is represented by a second coin datum memorized in a second memory part (28). The additional function is achieved in response to the second coin datum and a third coin datum representative of a coin which is deposited as the deposited coin into the coin sorting device. The fundamental function is achieved in response to the first and the third coin data.
    • 在具有用于判断所存放的硬币是否包含在真实硬币种类中的基本功能的硬币分类装置中,提供附加功能来判断所存放的硬币是否包含在虚假类型中。 真实种类由存储在第一存储器部分(27)中的第一硬币数据表示。 假币类型由存储在第二存储器部分(28)中的第二硬币数据表示。 响应于第二硬币数据和代表硬币的第三硬币数据被作为存放的硬币沉积到硬币分类装置中来实现附加功能。 响应于第一和第三硬币数据实现基本功能。

    • A sound mixing apparatus includes mixing processing units 11 to 1k provided according to sampling frequencies. Each of mixing processing units 11 to 1k adds up input sound signals of the same sampling frequency to generate a first added-up sound signal, converts the sampling frequency of the first added-up sound signal into a sampling frequency processable by the other mixing processing units, and supplies sound signals that are converted to the sampling frequency, to the other mixing processing units, adds up, to generate a second added-up sound signal, the first added-up sound signal generated by itself and the first added-up sound signals that are converted to a sampling frequency processable by itself and that are supplied from the other mixing processing units.

    • A sound data decoding apparatus based on a waveform coding method includes a loss detector, sound data decoder, sound data analyzer, parameter modifying section and sound synthesizing section. The loss detector detects whether a loss exists in a sound data. The sound data decoder decodes the sound data to generate a first decoded sound signal. The sound data analyzer extracts a first parameter from the first decoded sound signal. The parameter modifying section modifies the first parameter based on a result of the detection of loss. The sound synthesizing section generates a first synthesized sound signal by using the modified first parameter. Thus, a deterioration of sound quality is prevented in the error compensation of sound data.
    • 一种基于波形编码方法的声音数据解码装置,包括损失检测器,声音数据解码器,声音数据分析器,参数修正部分和声音合成部分。 损失检测器检测声音数据中是否存在损失。 声音数据解码器对声音数据进行解码以产生第一解码声音信号。 声音数据分析器从第一解码声音信号中提取第一参数。 参数修改单元根据损失检测的结果修改第一个参数。 声音合成部通过使用修改的第一参数来生成第一合成声音信号。 因此,在声音数据的误差补偿中防止声音质量的恶化。
