摘要： A metal seated floating ball valve for in-line repair has a valve body, a ball mounted in the valve body, a stem connected to the ball, and a bonnet connected to the valve body. The floating ball valve further has a first seat and a second seat adjacent the ball mounted in the valve body, an energizing ring mounted in the valve body proximate the first seat and in series with the first seat and the second seat, and a valve seat bias mounted in the valve body proximate the energizing ring and in series with the energizing ring. The energizing ring may have a slot near the upper end and a wedge surface along the lower end.

摘要： A disk control device stores write requests from a cache memory or reads commands from a host in a queue for a disk drive in chronological order. When the number of write requests stored in the queue for the disk drive is greater than a predetermined value, the storage location of write requests is changed to a queue for an extra disk drive, and the write requests are stored in the queue for the extra disk drive. When the number of write requests stored in the queue for the disk drive becomes smaller than a predetermined threshold, the write requests stored in the extra disk drive are written back to the disk drive.
