    • In a copying apparatus having an original-supporting surface capable of supporting thereon a thick original and a sheet-original exposure and transport portion, the original-supporting surface and the exposure surface of the sheet-original exposure and transport portion are formed separately and independently of each other or formed integrally with each other. The apparatus further includes an optical system for directing the image of an original to a photosensitive medium, and various copying process means. When an original on the original-supporting surface is to be copied, the optical system scans the original while moving along the original-supporting surface. When a sheet original is to be copied, the optical system is fixed to correspond to the exposure surface spaced apart from the original-supporting surface and the sheet original is passed through the sheet-original transport portion for scanning.
    • 在具有能够在其上支撑厚原稿和原稿曝光和输送部分的原稿支撑表面的复印装置中,原稿曝光和输送部分的原始支撑表面和曝光表面分别独立地形成 或彼此一体形成。 该装置还包括用于将原稿的图像引导到感光介质的光学系统,以及各种复印处理装置。 当原始支撑表面上的原稿被复制时,光学系统沿着原始支撑表面移动时扫描原稿。 复印原稿时,光学系统被固定成与原始支承面间隔开的曝光面相对应,片材原稿通过纸张原稿传送部分进行扫描。

    • A rotary vane compressor comprises a cylinder having two closed ends defining a cylinder chamber in which is rotatably mounted a rotor. The rotor carries a plurality of radially movable vanes which move radially into sliding contact with the inner surface of the cylinder chamber during rotation of the rotor to compress a refrigerant gas. The rotor is rotationally driven by a rotor shaft rotatably mounted by bearings in the cylinder ends. To prevent destruction of the ozone layer, a refrigerant containing no chlorine, such as HFC-134a (1,1,1,2-tetrafluoroethane; CH.sub.2 FCF.sub.3) is used, and to compensate for the inferior lubricating properties of the chlorine-free refrigerant, the bearings are provided with a manganese phosphate coating of 10 .mu.m-15 .mu.m thickness to prevent cohesion and seizure of the mutually contacting surfaces of the bearings and rotor shaft.
    • 旋转叶片压缩机包括具有限定汽缸室的两个封闭端的气缸,其中可旋转地安装有转子。 转子承载多个可径向移动的叶片,其在转子旋转期间径向地与气缸室的内表面滑动接触以压缩制冷剂气体。 转子由转子轴旋转驱动,该转子轴通过圆筒端部中的轴承可旋转地安装。 为了防止破坏臭氧层,使用HFC-134a(1,1,1,2-四氟乙烷; CH 2FCF 3)等不含氯的制冷剂,为了补偿无氯制冷剂的润滑性差, 该轴承设置有10μm-15μm厚的磷酸锰镀层,以防止轴承和转子轴相互接触的表面的内聚力和卡滞。
