摘要： The present invention is a method for reclaiming a silicon wafer in which a thin film has been formed on its surface, at least, comprising a thin-film removing step for removing the thin film having been formed on the silicon wafer and a mirror-polishing step for mirror-polishing at least one side of the thin-film-removed silicon wafer, wherein, before performing the mirror-polishing step, gettering-site forming treatment for applying damage load to at least one side of the silicon wafer is performed and then the silicon wafer is subjected to heat treatment, thereby impurities inside the silicon wafer are reduced. Thereby, there is provided a method for reclaiming a silicon wafer, in which a thin film such as a metal thin film having been formed on a silicon wafer can be removed, and impurities having diffused inside the wafer can be also reduced, thereby silicon wafers having very little metal contamination can be stably obtained.

摘要： A data reproduction apparatus is provided to supply audio data without sound skipping caused by positional deviation in read position, while avoiding an increase in circuit area. In one embodiment, the data reproduction apparatus includes a reading unit for optically reading data recorded on a recording medium. A first signal processing circuit produces a format data signal based on the data read by the reading unit. A second signal processing circuit performs a demodulation process on the format data signal to produce a demodulated format data signal including main data and subcode data. The second signal processing circuit also subjects the main data signal to a decoding process to produce a reproduced data signal. A buffer memory temporally stores the reproduced data signal. A shockproof controller controls the writing and reading of the reproduced data signal into and from the buffer memory. An operation controller causes the shockproof controller to stop the writing of the reproduced data signal in the buffer memory and causes the reading unit to repeat the reading of the data associated with the interrupted format data signal when the format data signal produced by the first signal processing circuit is interrupted. Further, when one of the operation controller and the shockproof controller receives the subcode data signal from the second signal processing circuit, the shockproof controller restarts the writing into the buffer memory of the reproduced data signal associated with the repeated reading of the data associated with the interrupted format data signal.
摘要翻译：提供数据再现装置，以便在避免电路面积的增加的同时提供音频数据，而不会由于读取位置的位置偏差而导致声音跳过。在一个实施例中，数据再现装置包括用于光学读取记录在记录介质上的数据的读取单元。第一信号处理电路基于由读取单元读取的数据产生格式数据信号。第二信号处理电路对格式数据信号执行解调处理，以产生包括主数据和子码数据的解调格式数据信号。第二信号处理电路还使主数据信号进行解码处理，以产生再现的数据信号。缓冲存储器暂时存储再现的数据信号。防震控制器控制将再生数据信号写入和读出缓冲存储器。操作控制器使得防震控制器停止对缓冲存储器中再现的数据信号的写入，并且当由第一信号处理产生的格式数据信号时，读取单元重复读取与中断格式数据信号相关联的数据电路中断。此外，当操作控制器和防震控制器中的一个接收到来自第二信号处理电路的子代码数据信号时，防震控制器重新开始向缓冲存储器写入与重复读取与数据相关联的数据相关联的再现数据信号中断格式数据信号。

摘要： In a valve actuation apparatus of a multi-cylinder engine employing a drive shaft rotatably arranged to extend over a plurality of cylinders, a drive cam attached to the drive shaft, and a motion transmitter provided for each of the cylinders for converting a rotary motion of the drive cam into an oscillating motion, a rockable-cam structural member is provided for each of the cylinders in a state where a shaft is inserted through inner peripheries of the rockable-cam structural members, for operating engine valves by the transmitted oscillating motion. A plain bearing is provided in at least one axial position between the axially-spaced rockable-cam structural members. An inner periphery of the plain bearing is in contact with an outer periphery of the shaft, whereas an outer periphery of the plain bearing is in contact with an inner periphery of a bearing portion mounted on the engine.
