    • A method for low-speed reproducing in a video cassette recorder (VCR) having a pair of main heads for normal-speed reproducing and at least a pair of additional heads neighboring said main heads is disclosed. A period which is regularly repeated from an envelope waveform of a video signal reproduced by said main heads is detected.

    • A Siemens type CVD reactor device is provided. One or more radiation shields are disposed between a rod filament and a cooled wall in the reactor. The radiation shield absorbs radiant heat emanating from the heated polysilicon rod during the CVD process, gets heated above 400° C., re-radiate the absorbed heat toward both of the polysilicon rod and the cooled wall, so as to provide thermal shielding effect to the cooled wall. The net energy loss of the polysilicon rod is reduced as much as the amount of energy emitted toward the polysilicon rod from the radiation shield, such that considerable amount of electrical energy of the CVD reactor is reduced and saved. The energy reduction rate goes up much higher if using multiple layered radiation shields, low shielding emissivity, and low thermal conductivity together. The purity of the manufactured polysilicon can be maintained by using thermal shielding material that is stable in a high temperature such as graphite, silicon carbide-coated graphite, and silicon.
    • 提供了西门子式CVD反应器装置。 一个或多个辐射屏蔽设置在反应器中的棒状细丝和冷却壁之间。 辐射屏蔽在CVD过程中吸收从加热的多晶硅棒发出的辐射热,被加热到400℃以上,将吸收的热量再次辐射到多晶硅棒和冷却壁两者,以便提供热屏蔽效应 冷却的墙壁。 多晶硅棒的净能量损失与从辐射屏蔽向多晶硅棒发射的能量的量减少一样多,使得可以减少并节省大量的CVD反应器的电能。 如果使用多层辐射屏蔽,低屏蔽辐射率和低热导率,能量减少率就会上升得更高。 制造的多晶硅的纯度可以通过使用在高温下稳定的热屏蔽材料来维持,如石墨,碳化硅涂覆的石墨和硅。

    • A capstan phase control method during slow playback and the servo system of a VCR adopting the same, for phase-controlling a capstan motor so that a slow motion picture can be viewed without having noise during slow playback of the VCR. The capstan phase control method and the servo system employing the same, sets a sampling frequency of a reference control signal corresponding to desired slow playback on the basis of a head switching signal, judges whether a phase of the reference control signal having the set sampling frequency is identical with that of the control signal read via a head from the tape, and controls the phase of the capstan motor so that the phase of the read control signal is identical with that of the reference control signal on the basis of the judgement result. Accordingly, since the capstan motor can be phase-controlled and speed-controlled during slow playback, a tracking control can be performed so that noise does not appear on a screen. Thus, a slow motion picture without having noise can be provided.
