  • Patent number: 10767706
    Abstract: A frictional engagement element includes: a first piston, a second piston, a first urging member for urging the first piston in a direction of releasing a friction plate, and a second urging member for urging the second piston in the direction of releasing the friction plate with an urging force larger than the urging force of the first urging member. One of the first and second pistons has a communicating hole for connecting an engaging hydraulic chamber with an opposite hydraulic chamber and the other of the first and second pistons has a valve part for closing the communicating hole. The difference in travel distance between the first and second pistons in motion due to the different urging forces of the first and second urging members causes the valve part to open the communicating hole.

  • Patent number: 10296429
    Abstract: A storage subsystem comprises one or more volumes, and multiple nodes having multiple control packages interconnected via an intra-node communication path, wherein the control packages of different nodes are interconnected via an inter-node communication path having a lower transmission path capacity than the intra-node communication path. When the host computer accesses a volume, access is enabled via any of at least two or more control packages out of the multiple control packages, and the priority for issuing access requests to the relevant volume is determined in each of the control packages. When the storage subsystem detects failure, it changes the priorities determined for the control packages according to the failure occurrence portion, and notifies the same to the host computer. The host computer determines the control package being the issue destination of the access request based on the notified priority.
