    • A collecting unit is disposed on an exhaust passage of a semiconductor processing apparatus to collect by-products contained in an exhaust gas. The collecting unit includes a trap body detachably disposed inside a casing and configured to collect a part of the by-products. The trap body includes fins arrayed in a flow direction of the exhaust gas and having a surface on which a part of the by-products is deposited and trapped. The collecting unit further includes a receiving mechanism disposed inside the casing and configured to receive a part of the by-products that peels off from the trap body or an inner surface of the casing to prevent this part from being deposited on a bottom of the casing. The receiving mechanism is configured to allow a part of the by-products held thereon to be in contact with a cleaning gas from above and from below.
    • 收集单元设置在半导体处理装置的排气通道上以收集废气中所含的副产物。 收集单元包括可拆卸地设置在壳体内并被构造成收集一部分副产物的捕集体。 捕集体包括排列在废气的流动方向上的翅片,并且具有一部分副产物被沉积并被捕获的表面。 收集单元还包括设置在壳体内部并被配置为接收从捕获体或套管的内表面剥离的一部分副产品的接收机构,以防止该部分沉积在壳体的底部 。 接收机构构造成允许其上保持的副产物的一部分与来自上下的清洁气体接触。

    • A video signal recording/reproducing device has at least a frequency modulating unit which FM modulates information to be recorded on an optical disk memory, a laser driving pulse generating unit for generating a laser driving pulse derived from the frequency-modulated signal generated by the frequency modulating unit and for modifying the duty factor of the laser driving pulse in accordance with the linear velocity of the optical disk memory where recording is taking place; and a recording unit for controlling the laser power during recording to an optimum value in accordance with the linear velocity of the optical disk memory where recording is taking place. This arrangement enables reduction of the minimal length of recording bits resulting in reproduced signals of a level sufficient for obtaining reproduced images of a fine quality addition enables increase of the recording capacity of the optical disk memory.
    • 视频信号记录/再现装置至少具有调制要记录在光盘存储器上的信息的频率调制单元,激光驱动脉冲产生单元,用于产生由频率产生的频率调制信号导出的激光驱动脉冲 并且用于根据正在进行记录的光盘存储器的线速度来修改激光驱动脉冲的占空因数; 以及记录单元,用于根据正在进行记录的光盘存储器的线速度将记录期间的激光功率控制到最佳值。 这种布置能够减少记录位的最小长度,从而产生足以获得精细质量附加的再现图像的再现信号,从而能够增加光盘存储器的记录容量。
