    摘要: An electrophotographic photosensitive drum is for a process cartridge detachably mountable to a main assembly of an electrophotographic image-forming apparatus. The process cartridge includes a charging roller for electrically charging the photosensitive drum and a developing roller for developing a latent image formed on the drum. The drum includes a drum helical gear, mounted to one end of the cylinder, for transmitting a rotational driving force to a transfer roller provided in a main assembly, and for transmiting a rotational driving force to the charging roller and the developing roller. A shaft portion is provided at a central portion of the drum helical gear at a position where it is completely overlapped with teeth of the drum helical gear with respect to a longitudinal direction of the cylinder. A gap is provided between the teeth and a peripheral surface of the shaft portion.

    摘要: A fin-tube type heat exchanger has parallel heat transfer tubes and a stack of a plurality of plate fins mounted on the tubes. Heat exchange is conducted between a first fluid flowing through the tubes and a second fluid flowing through the stack across each of the fins. Each fin has flat tube-mounting portions spaced in the longitudinal direction of the fin and formed with tube-mounting holes and a louver section disposed between each adjacent pair of tube-mounting portions. The louver section has elongated slats extending longitudinally of the fin and having side edges each spaced from an adjacent side edge of an adjacent slat. The slats are classified into two groups in respect of the cross-sectional shape. The slats of one group have generally flat cross-sections to reduce the resistance of the fin to the flow of the second fluid through the stack and are disposed in planes offset from the plane of the tube-mounting portions. The slats of the other group have V-shaped or inverted V-shaped cross-sections to increase stiffness of the fin in the longitudinal direction thereof.

    摘要: A magazine for holding a plurality of articles, such as cartons, which are to be singularly withdrawn at a downstream end, and a method of feeding articles. The magazine includes guides, spaced apart by a distance greater than the width of the cartons in their folded condition, thereby creating a gap between an inner guide surface and one of the edges of the cartons. A pair of stoppers project from the inner guide surfaces and are spaced apart by a distance less than the width of the cartons, to thereby hold the most downstream carton in a position to facilitate its withdrawal at the discharge end of the magazine. A feed roller projects from one inner guide surface toward the other inner guide surface upstream of the discharge end. At least one carton is engaged between the roller and the other inner guide surface to isolate a predetermined number of folded cartons downstream of the feed roller from a second predetermined quantity of folded cartons upstream of the feed roller. Further, due to the engagement of the edges of the most downstream carton and the stoppers, as the carton is withdrawn from the magazine, the carton is more fully opened to thereby facilitate its subsequent complete opening. A supply conveyor is provided upstream of the guide surfaces. The supply conveyor and the feed roller can be driven synchronously in response to the sensing of a reduction in the quantity of cartons in the downstream portion of the magazine.
