    • A gas generator includes a container having an outer shell; a gas initiator disposed in the container; an igniter for igniting the gas initiator; and a partition disposed in the outer shell for dividing the container into a plurality of gas initiator chambers and having a positioning member for positioning the igniter in an inserting direction of the igniter into the partition. The igniter can be positioned inside the partition with high accuracy.
    • 气体发生器包括具有外壳的容器; 设置在容器中的气体引发器; 用于点燃气体引发剂的点火器; 以及设置在所述外壳中的隔板,用于将所述容器分成多个气体起动器室,并具有用于将所述点火器沿所述点火器的插入方向定位到所述隔板中的定位构件。 点火器可以高精度地定位在分区内。

    • An optical disc recording apparatus records a digital content onto an optical disc so that the perfect copying of the digital content is difficult without proper authorization. The optical disc recording apparatus includes a formatter for generating a channel signal corresponding to primary digital information, a secret key storing unit for prestoring secondary digital information, a pseudo random number generator for generating a pseudo random number series, an XOR for logically inverting the pseudo random number series according to each bit of the secondary digital information, a PE modulator for generating a PE modulation signal according to the logically inverted pseudo random number series, a phase modulator for modulating the phase of each edge of the channel signal by a fixed slight time according to the value of the PE modulation signal, and a recording channel for forming recording marks on a DVD according to the modulated channel signal.
    • 光盘记录装置将数字内容记录到光盘上,使得在没有适当授权的情况下数字内容的完美复制是困难的。 光盘记录装置包括用于产生对应于主数字信息的信道信号的格式器,用于预存次数字信息的秘密密钥存储单元,用于产生伪随机数序列的伪随机数发生器,用于逻辑反转伪随机数序列的伪异或 根据第二数字信息的每一位的随机数序列,用于根据逻辑反相伪随机数序列产生PE调制信号的PE调制器,用于通过固定的微调对通道信号的每个边沿的相位进行调制的相位调制器 根据PE调制信号的值的时间,以及根据调制信道信号在DVD上形成记录标记的记录通道。
