    • 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.
    • 电子照相感光鼓用于可拆卸地安装到电子照相成像设备的主组件上的处理盒。 处理盒包括用于使感光鼓充电的充电辊和用于显影形成在感光鼓上的潜像的显影辊。 滚筒包括安装在滚筒一端的滚筒螺旋齿轮,用于将旋转驱动力传递到设置在主组件中的转印辊,并将旋转驱动力传递到充电辊和显影辊。 在滚筒斜齿轮的中心部分处设置有一个轴部分,该位置与滚筒螺旋齿轮的齿相对于气缸的纵向方向完全重叠。 在齿与轴部的周面之间设有间隙。

    • 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.
    • 翅片管型热交换器具有平行的传热管和安装在管上的多个板翅片的堆叠。 在流过管的第一流体和跨过每个翅片流过堆叠的第二流体之间进行热交换。 每个翅片具有在翅片的纵向间隔开的扁平管安装部分,并且形成有管安装孔和布置在每个相邻的一对管安装部分之间的百叶窗部分。 百叶窗部分具有从翅片纵向延伸的细长板条,并且具有与相邻板条的相邻侧边缘间隔开的侧边缘。 板条在横截面形状上分为两组。 一组的板条具有大致平坦的横截面,以减小翅片对通过堆叠的第二流体的流动的阻力,并且设置在从管安装部分的平面偏移的平面中。 另一组的板条具有V形或倒V形横截面,以增加翅片在其纵向上的刚度。

    • 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.
