A method, system and computer-usable medium are disclosed for initiating a session in a virtual world. An instant messaging system (IMS) comprises a registry of IMS user identifiers cross-referenced to their corresponding virtual world user identifiers. A first IMS user implements a virtual world invitation module as a result of an IMS session to invite a second IMS user to participate in a virtual world session. The first IMS user selects the IMS user identifier of the second IMS user, followed by selection of a target virtual world and a virtual world identifier. Once completed, the invitation is sent the IMS user identifier of the second IMS user, who receives the invitation and signifies their acceptance or declination. If accepted, the cross-referenced virtual world user identifiers of the first and second IMS users are used to log them into the agreed-upon virtual world venue and initiate a virtual world session.

A drive transmitting mechanism configured to rotate the photosensitive drum of a color copier has a driving shaft, a driven shaft, and first and second coupling members. The first coupling member has a projection extending in a diametrical direction. The first coupling member is attached to the driving shaft, with amount of freedom to oscillate in a direction intersecting at right angles to the lengthwise direction of the projection. The second coupling member has a recess in which the projection is fitted.
