  • Publication number: 20160330250
    Abstract: A control system includes controllers controlling a session between communication terminals. Each controller includes a state management unit, first and second updating units, and a receiver. The state management unit manages state information of each terminal indicating a state of connection between the terminal and the controller. When the state of connection between a first terminal and the controller is changed, the first updating unit updates state information of the first terminal. When the state of connection between a second terminal and another controller is changed, the receiver receives, from the other controller, changed state information of the second terminal indicating a state of connection between the second terminal and the other controller after being changed. The second updating unit updates the state information of the second terminal based on the received changed state information. The controller controls the session between the terminals based on the state information.

  • Patent number: 9454099
    Abstract: An image forming apparatus includes a lid pulling mechanism that includes a hook to open a toner discharge opening by pulling, from the bottle head section, a lid member that is in contact with a bottle head section of a toner bottle to close the toner discharge opening, and the lid pulling mechanism pulls the lid member in a direction inclined upward with respect to a virtual line that extends in a horizontal direction. Therefore, the distance is decreased between the lid member and the bottle head section and above the toner discharge opening through which air easily passes; thus, intake of air from the outside to the inside of the bottle head section is prevented. Furthermore, it is possible to prevent the occurrence of spread of toner from the inside of the bottle head section to the outside of the container.

  • Publication number: 20160277414
    Abstract: A management device manages information of a task having been executed by users cooperatively. An electronic data access unit accesses electronic data by using authentication information of a corresponding user. A management unit manages, for each task, task information in which pieces of authentication information of the users having participated in the task are associated with access destination information. A receiver receives a request, from a user, for access to the electronic data. When the electronic data access unit needs the authentication information of a user different from the requester user having participated in the task same as the task in which the requester user has participated to access the electric data as a target of the request, the electronic data access unit acquires the authentication information of the different user based on the task information and accesses the electronic data using the acquired authentication information of the different user.
