    • An exposure device comprising a table having a plane on which an original is placed, a light emitting device for emitting a light on the original placed on the plane, a scanning device for scanning the original on the plane while the emitting device is being moved along the plane, and a light adjusting device for adjusting the quantity of light emitted from the emitting device. The light adjusting device includes a shutter adapted to narrow the path of light emitted from the emitting device and adjust the quantity of light, an urging member for urging the shutter in a predetermined direction, an operating member for operating the shutter against the urging force of the urging member, when the emitting device is being moved and the shutter abuts against the operating member, and a holding device for holding the shutter, which has been moved to a predetermined position by the operating member, until the shutter abuts against the operating member again.
    • 一种曝光装置,包括具有放置原稿的平面的台,用于在放置在平面上的原稿上发射光的发光装置,用于在发射装置移动时在平面上扫描原稿的扫描装置 平面以及用于调节从发光装置发出的光量的调光装置。 调光装置包括一个适于缩小从发射装置发射的光的路径并调节光量的快门,一个用于沿预定方向推动挡板的推动部件,一个操作部件,用于克服该挡板的作用力 当所述发射装置被移动并且所述快门抵靠所述操作构件时,所述推动构件以及用于保持已被所述操作构件移动到预定位置的所述快门的保持装置,直到所述快门抵靠所述操作构件 再次。

    • A position in which an image of a second document is inserted into an image of a first document is designated by operating an operation panel. A scanner unit reads the image of the first document and a printing unit prints the read image of the first document on paper. That area of the first document image to be printed by the printing unit in which the image of the second document is inserted is masked. Paper on which the first docment image has been printed and an ink ribbon are set back to a position at which the printing operation for the first document image is started before the second document image is printed. The scanner unit reads the second document image and the printing unit prints the second document image read on a designated area of the paper on which the first document image has been printed by using ink of that portion of the ink ribbon which has not been used for printing the first document image.
    • 通过操作操作面板指定将第二文档的图像插入到第一文档的图像中的位置。 扫描器单元读取第一文件的图像,并且打印单元将第一文档的读取图像打印在纸上。 被插入第二文档的图像的打印单元要打印的第一文档图像的区域被遮蔽。 在打印第二文档图像之前,已经打印了第一文档图像的打印纸和墨带被设置回到第一文档图像的打印操作开始的位置。 扫描仪单元读取第二文档图像,并且打印单元通过使用未被使用的墨带的那部分的墨水打印在已经打印了第一文档图像的纸张的指定区域上读取的第二文档图像 打印第一个文档图像。

    • A method for the preparation of a novel recombinant DNA, which comprises (1) cleaving with an endonuclease a temperate phage DNA having an endonuclease-sensitive region not in the DNA segment participating in the replication of phage DNA and the integration of phage DNA into a host chromosome but at least in the DNA segment carrying genetic information for the coat protein production and another DNA carrying intended genetic information, (2) adding DNA-ligase to the mixture of both cleft DNA's, and (3) recovering from the mixture a phage DNA having its coat protein producing ability deleted by the replacement of the DNA segments carrying genetic information for the coat protein production with a DNA fragment carrying the intended information.
    • 一种制备新的重组DNA的方法,其包括(1)用核酸内切酶切割温和的噬菌体DNA,所述温带噬菌体DNA具有参与噬菌体DNA复制的DNA片段中不具有内切核酸酶敏感区域,并将噬菌体DNA整合到 宿主染色体,但至少在DNA片段中携带外壳蛋白生产的遗传信息和携带预期遗传信息的另一个DNA,(2)向裂解DNA的混合物中加入DNA连接酶,和(3)从混合物中回收噬菌体 通过用携带预期信息的DNA片段替代携带用于外壳蛋白生产的遗传信息的DNA片段,缺失其外壳蛋白产生能力的DNA。
