    • Power supplying unit to be used for supplying power to such a load as the motor for driving a submerged pump that scoops liquid out of a tank storing low temperature liquid like LNG and so forth. The power supplying unit has a ceramic sleeve fixed to the flange, a penetrating conductor inserted into this ceramic sleeve, and the ceramic sleeve and the penetrating conductor are coupled air-tightly to each other inside the flange (inside the tank) sealed outside the flange with a bellows of semi-mountain construction in cross section. The bellows has an elasticity and is mounted, when the ceramic sleeve and the penetrating conductor are linearly expanded at the maximum temperature during practical or normal use, or at the temperature slightly higher than the said level. The bellows is mounted between the ceramic sleeve and the penetrating conductor in a state where it is displaced to its maximum length due to its self elasticity. The bellows has been structured in such that it may absorb the reaction force being generated, when the penetrating conductor has linearly expanded, as a compression onto the side of ceramic sleeve for preventing it from acting as an tensile stress.

    • An image recording apparatus for recording an image corresponding to an original on a photosensitive recording medium by irradiating light onto the original and converging light from the original onto the photosensitive recording medium. The apparatus includes a lens unit vertically movably supported by the frame, a plurality of position setting holes arrayed in a vertical direction of the frame, position setting means provided on the lens unit and capable of being inserted into one of the position setting holes for fixing the lens unit to the frame, urging means provided on the lens unit for urging the position setting means toward the frame to project the position setting means, actuating means provided on the lens unit for actuating the position setting means so that the position setting means retracts and moves away from the frame against urging force of the urging means when electric current is supplied to the actuating means. The apparatus further includes control means for controlling the actuating means so that when an error is detected during movement of the lens unit, electric current to the actuating means is cut off to project the position setting means by the urging force of the urging means and to fix the lens unit to the frame.
    • 一种图像记录装置,用于通过将光照射到原稿上并将来自原稿的光会聚到感光记录介质上,将与原稿对应的图像记录在感光记录介质上。 该装置包括由框架上下移动地支撑的透镜单元,沿着框架的垂直方向排列的多个位置设定孔,设置在透镜单元上的位置设定装置,能够插入到固定位置设定孔 透镜单元到框架,设置在透镜单元上的推动装置用于将位置设定装置推向框架以突出位置设定装置,设置在透镜单元上的致动装置,用于致动位置设定装置,使得位置设定装置缩回 并且当电流被供应到致动装置时,抵抗推动装置的推动力而远离框架移动。 该装置还包括用于控制致动装置的控制装置,使得当在透镜单元的移动期间检测到误差时,切断对致动装置的电流,以通过推动装置的推动力使位置设定装置突出,并且 将镜头单元固定到框架上。
