  • Patent number: 11044319
    Abstract: An equipment analysis support apparatus includes an equipment constraint information storage unit that stores equipment constraint information which is a correspondence relationship between each process constituting work performed using a plurality of pieces of equipment and a constraint to be imposed on the equipment in each process; a work process information acquisition unit that acquires work process information which is information on a process of the work currently in progress; a configuration information generation unit that, when it is determined that a current work state is changed, specifies a constraint to be imposed on the equipment in the changed work state and generates a configuration of analysis processing of the equipment satisfying the specified constraint based on the acquired work process information and the equipment constraint information; and a processing execution unit that performs processing necessary for analysis of the equipment based on the generated configuration.

  • Patent number: 9647910
    Abstract: Methods and apparatuses for managing a service system virtually built are provided. A management server assigns identifiers that are unique to a service system to components used to build the service system, and records connections of the components and the time of building the service system. When detecting a change in the connections of the components, the management server records the changed connection and the time of the change, collects monitoring information and monitoring times from a data center, and records the monitoring information associated with the monitoring times. When receiving information designating a time from a terminal, the management server identifies and outputs the configuration of the service system and the monitoring information at the designated time based on the identifiers of the components associated with the designated time.

  • Publication number: 20150172148
    Abstract: A management server assigns identifiers unique to a service system to components used to build the service system, and records connections between the components assigned the identifiers associated with a time of the building the service system. When detecting a change in the connections of the components included in the service system, the management server records the changed connection associated with a time of the change of the connection, collects monitoring information indicating operation conditions of the components and monitoring times from a data center, and records the monitoring information associated with the monitoring times. When receiving information designating a time from the management terminal, the management server identifies and outputs the configuration of service system and the monitoring information at the designated time based on the identifiers of the components associated with the designated time.

  • Patent number: 7977844
    Abstract: An inductor-type synchronous machine having an axial gap structure, which has a shaft portion at the center thereof, the machine includes: a field-side stator which has a yoke made of a magnetic material and a field body protruding from the yoke in an axial direction of the shaft portion to form an N pole and an S pole in a radial direction; a rotor which has N pole inductors disposed so as to be opposed to the N pole formed by the field body and S pole inductors disposed so as to be opposed to the S pole formed by the field body; and an armature-side stator in which an armature coil is disposed so as to be opposed to the N pole inductors and the S pole inductors.
