摘要： In a roller chain in which a plurality of rolling bodies is disposed between a roller and a bushing, between a bushing and a pin, or between a roller and a pin, the rolling bodies include at least one carbon-impregnated ceramic rolling body, or at least one carbon-coated steel rolling body. Preferably, the carbon-impregnated or carbon-coated rolling bodies are disposed in an alternating configuration with steel rolling bodies.

摘要： A method and system for relaying a file object used in a gateway computer allowing the change of various parameters settings, dependent on particular networks, in a simple manner. The method and system further allowing reference of a file object referred to when a client computer was first connected to a certain network even when the client computer is then connected to another network in a simple manner. The method and system provides for relaying a file object in accordance with any of a plurality of control structures corresponding to a plurality of networks, respectively. The gateway computer includes storage for storing a file object. Each of the plurality control structures has an address of a representative gateway computer to which a client computer is connected. The method of relaying the file object includes the steps of receiving an event, when the event is a request for switching between the control structures, switching various parameters in accordance with that one of the control structures to which switching is requested, when the event is a request for getting the file object transmitted by the client computer, reading and relaying to the client computer the file object from either one of an upstream computer and the storage, and storing the relayed file object in the storage.
摘要翻译：一种用于中继在网关计算机中使用的文件对象的方法和系统，其允许以简单的方式依赖于特定网络来改变各种参数设置。即使当客户端计算机以简单的方式连接到另一个网络时，该方法和系统还允许引用客户端计算机首先连接到某个网络时所引用的文件对象。该方法和系统提供分别根据与多个网络对应的多个控制结构中的任何一个中继文件对象。网关计算机包括用于存储文件对象的存储。多个控制结构中的每一个具有与客户端计算机连接的代表性网关计算机的地址。中继文件对象的方法包括以下步骤：当事件是在控制结构之间切换的请求时，接收事件，根据请求切换的控制结构中的一个切换各种参数，当事件为请求获取由客户端计算机发送的文件对象，从上游计算机和存储器中的任一个读取和中继到客户端计算机的文件对象，并将中继的文件对象存储在存储器中。

摘要： A cylindrical roller bearing includes a plurality of cylindrical rollers disposed between a circular outer race and a circular inner race without using a retainer. The inner and outer races are devoid of annular flanges extending radially from opposite axial ends of the races for controlling the position of the cylindrical rollers in an axial direction. A pair of thrust bearing plates are disposed on the opposite sides of the outer race for controlling the positions of the outer race and the cylindrical rollers in the axial direction. One or more of the cylindrical rollers are formed shorter than the other cylindrical rollers. With this arrangement, a skew of one or more of the cylindrical rollers, which may occur when the outer race is subjected to an axial load, is taken up by circumferential gaps formed between the shorter cylindrical roller and adjacent cylindrical rollers at opposite ends of the shorter cylindrical roller. Thus, rotation of the outer race is stable and abrasion between the end faces of the cylindrical rollers and the thrust bearing plates can be suppressed.
摘要翻译：圆柱滚子轴承包括多个圆柱滚子，其设置在圆形外座圈和圆形内座圈之间，而不使用保持器。内圈和外圈没有从座圈的相对轴向端部径向延伸的环形凸缘，用于控制圆柱滚子在轴向上的位置。一对推力轴承板设置在外圈的相对侧上，用于控制外圈和圆柱滚子在轴向方向上的位置。一个或多个圆柱滚子形成得比其它圆柱滚子更短。通过这种布置，当外圈承受轴向载荷时可能发生的一个或多个圆柱滚子的歪斜被在较短的圆柱滚子和邻近的圆柱滚子之间形成的周向间隙吸收，较短的圆柱滚子。因此，外圈的旋转是稳定的，并且可以抑制圆柱滚子的端面与止推轴承板之间的磨损。

摘要： A cantilever shaft assembly includes a steel pipe firmly secured at one end to a wall surface of a stationary support member, and a core shaft made from a synthetic resin and having a body portion removably fitted in the steel pipe and an end portion located outside the steel pipe. The end portion forms a free end of the cantilever shaft assembly and rotatably supports thereon a rotating member such as a driven sprocket. The core shaft and the steel pipe are locked and held together by a locking device such as a pin or a key. The cantilever shaft assembly is light in weight and can be easily repaired at a low cost when the end portion of tne synthetic resin core shaft is damaged or worn out.
摘要翻译：悬臂轴组件包括：一端牢固地固定在固定支撑构件的壁面上的钢管，以及由合成树脂制成的芯轴，并且具有可拆卸地装配在钢管中的主体部分和位于外侧的端部钢管。端部形成悬臂轴组件的自由端，并且在其上可转动地支撑有诸如从动链轮的旋转构件。芯轴和钢管通过诸如销或钥匙的锁定装置锁定并保持在一起。悬臂轴组件重量轻，当合成树脂芯轴的端部损坏或磨损时，可以以较低的成本轻易修理。
