Title: Storage device system and its control method
Inventor: MORISHITA NOBORU
IPC: G06F12/16
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To replace a storage medium without requiring operator's operation and stopping the operation of the storage device system which uses a portable storage medium whose update frequency is limited. SOLUTION: A storage controller 2 controls the update frequency by updating medium update frequency control information 251 each time a medium 331 is rewritten or controls the rest of reserved blocks. When the update frequency exceeds a threshold or when the number of remaining blocks decreases below a threshold, a reserved medium copying process 263 copys the contents of the medium 331 to a backup medium 332. Then the backup medium 332 is stored in a storage 33 instead of the copy-source-medium 331, which is ejected to an ejection slot 35. As a backup medium loading process 264 is started by a maintenance terminal 4, the backup medium 332 loaded in a loading slot 34 is stored in the storage 33 to perform replenishment with the backup medium 332.

A pressure regulator 6 supplies only required fuel out of filtered fuel to a supply passage 12 and returns unrequired fuel to the tank 1. The required fuel is supplied to the delivery pipe 4 of an engine part 10 through a check valve 8 and then injected from fuel injection valves 5. At this time, the check valve 8 is opened and closed according to the differential pressure of fuel, and closed according to the stop of the engine 10. Therefore, fuel pressure on the rear part of the check valve 8 is raised to the set pressure or more of the pressure regulator 6 in restarting of the engine 10.
