  • Backup system, method therefor, and program
    Patent number: 11977450
    Abstract: Backup system and method that can determine a backup destination in consideration of disaster are provided. There are provided: a data acquisition unit 110 that acquires disaster information, network information, and node information; a replication group construction unit 130 that generates, based on the disaster information, and the like, replication group information including association information between a first node that stores original data and one or more second nodes that are candidates for backup destination of the original data, and saves the replication group information in a storage unit 120; a replication destination node calculation unit 140 that, when executing backup of the original data, calculates the second node as backup destination from the replication group; and a replication processing unit 230 that replicates and stores the original data into the storage of the second node.

  • Continuously-variable transmission for vehicle
    Patent number: 8620539
    Abstract: A continuously-variable transmission for a vehicle includes a belt-type continuously-variable transmitting mechanism connected to a drive source and configured to continuously vary a speed ratio of the belt-type continuously-variable transmitting mechanism; an auxiliary transmitting mechanism provided in series with the belt-type continuously-variable transmitting mechanism and configured to attain a plurality of shift steps for a forward running of the vehicle; and a speed-increasing gear mechanism provided upstream from the auxiliary transmitting mechanism and configured to increase an input rotational speed of the auxiliary transmitting mechanism.
