Patent number: 9699210Abstract: A data processing device, that includes: a first storage device; and a processor configured to execute a procedure. The procedure includes: receiving write data to be written to a second storage device provided at a computer, outputting the write data to the second storage device, and duplicating and outputting the write data; executing control that writes the duplicated write data to the first storage device that is separate from the second storage device; executing virus countermeasure processing related to virus infection, on the write data stored in the first storage device; and in a case where the write data is output while executing the virus countermeasure processing, suspending the virus countermeasure processing and prioritizing execution of the control that writes the duplicated write data to the first storage device.Type: GrantFiled: March 24, 2015Date of Patent: July 4, 2017Assignee: FUJITSU LIMITEDInventors: Tomohiro Miura, Syouichi Kamio, Satoru Fukuda, Kaoru Iguchi, Yoshikazu Takahashi

Patent number: 6279716Abstract: An apparatus for movably supporting an article includes a plurality of raising units arranged in a row on a mount, with their outer side surfaces contacting with those of adjacent ones. Each raising unit includes a lifting member including a piston and a ball disposed on top of the piston. A casing has a cylinder bore which is formed therein to open upward and in which the lifting member is disposed to be vertically movable. A pressure chamber is formed beneath the piston. A portion of the ball can protrude through the opening when the lifting member is raised. An air path extends from one to opposite side surfaces of the casing through the pressure chamber. When compressed air is supplied to the pressure chamber of the raising unit at one end of the row, it is also supplied to the pressure chambers of the remaining raising units.Type: GrantFiled: January 25, 2000Date of Patent: August 28, 2001Assignees: SR Engineering Company, Limited, Iguchikiko Seisakusho Company, LimitedInventors: Fuminori Kayatani, Yukinobu Iwasaki, Hidenori Kono, Kaoru Iguchi
