  • Publication number: 20200353447
    Abstract: Provided is, for example, an exhaust gas-purifying three-way catalyst which is suppressed in particle growth due to sintering of a catalytically active component on a carrier in exposure to a high temperature and thus is enhanced in purification performance, and a method for producing the same, as well as an integral structure type exhaust gas-purifying catalyst using the same. The exhaust gas-purifying three-way catalyst of the present invention includes a composite particle which contains a base material particle having a pore size of 100 to 650 nm as measured by a mercury intrusion method and a catalytically active particle of a platinum group element supported on the base material particle, in which a content proportion of the catalytically active particle is 0.001 to 30% by mass in total in terms of metal of the platinum group element, based on a total amount of the composite particle.

  • Patent number: 10372385
    Abstract: Provided is a management server that is used in constructing a high-quality test environment. The management server is an operating server that is connected via a network to an image forming apparatus registered as a management target, and that remotely manages the image forming apparatus. The management server includes a data-collection unit, a connection-receiving unit, and a data-relay unit. The data-collection unit receives collection-target data from the image forming apparatus and accumulates that data in a database. The connection-receiving unit receives a connection with a test sever having the same functions as self server. The data-relay unit also transmits the collection-target data received by the data-collection unit to the test server, the connection of which is received by the connection-receiving unit. Therefore, the collection-target data is accumulated in the test server in the same way as in the management server, and can be used as test data.

  • Publication number: 20180349071
    Abstract: Provided is a management system that, recovers the image forming apparatus to being online by remote control from the management server. The image forming apparatus management system includes a message-receiving apparatus for receiving control instructions from the management server via a communication path (mobile telephone network) that is separate from a network. The management server detects an image forming apparatus of which the connection with a server-communication unit becomes offline as an offline apparatus. Then, the management server transmits a control instruction to the message-receiving apparatus via the communication path for causing the offline apparatus to recover the connection with the server-communication unit to online.

  • Patent number: 9928351
    Abstract: A license management server manages a license to perform a service of remote maintenance related to one or more image forming apparatuses installed in a customer's site. The maintenance server includes a maintenance unit and a history management unit. If the license management server notified of expiration of an expiration date of the license defined by a contract, the maintenance unit stores history information acquired from the one or more image forming apparatuses corresponding to the expired license into a storage unit, and stops the service. If the license management server notified of grant of the license by a re-contract, the history management unit obtains the history information about the one or more image forming apparatuses corresponding to the granted license from the storage unit, and passes the obtained history information to the maintenance unit. By using the passed history information, the maintenance unit resumes the service.

  • Publication number: 20170017910
    Abstract: A license management system includes an image forming apparatus and a license management server. The license management server includes a group management database, a license management database, a time zone information table, a group management unit, and a license management unit. The group management database stores information indicating an organization to which the license is assigned. The information relates to a group to which the image forming apparatus belongs. The license management database stores information on the license for the group. The time zone information table describes information on a working hour in a time zone where the group is present. When the one working hour ends, the license management unit that re-assigns the license from the group in the ended working hour to the group in another working hour based on the time zone information table, the license management database, and a current time.
