    • A novel thin film transistor (TFT) structure for minimizing parasitic capitances on both the drain and source electrodes. According to a first embodiment, a triple gate TFT is provided with an open gate structure in which the source and drain electrodes are non-overlapping with the top gate electrode. A pair of bottom gate electrodes being aligned respectively with the first gap between the gate and source and the second gap between the gate and drain. According to a second embodiment of the invention, a full transfer TFT switch is provided having a source, a drain, a bottom gate and semi-conductor layer therebetween, and a partial top gate overlapping a portion of the drain and a portion of the semiconductor layer for creating a generally triangular-shaped charge density distribution in the semiconductor layer for moving channel electrons toward the source electrode.

    • The invention is concerned with a means of compensating for film shrinkage in a continuous film motion telecine apparatus. A measure of the film shrinkage is obtained by deriving a signal representing the angular speed of a roller in non-slipping contact with the film, the film being driven at a constant frame rate by, for example, a smooth capstan servo-controlled to maintain the constant frame rate. The roller whose angular speed is measured may be the drive capstan itself or a separate roller. The signal so derived is dependent on the film shrinkage and thus is used to automatically control a registration adjusting means to compensate for such shrinkage.
    • 本发明涉及一种在连续薄膜运动电视电影装置中补偿薄膜收缩的方法。 通过导出表示与膜非滑动接触的辊的角速度的信号来获得膜收缩的量度,膜通过例如伺服控制的平滑绞盘以恒定的帧速率驱动,以维持 恒定帧速率。 测量角速度的辊可以是驱动绞盘本身或单独的辊。 所得到的信号取决于膜收缩,因此用于自动控制配准调节装置以补偿这种收缩。
