Patent number: 10148518Abstract: A management apparatus transmits a plurality of probe packets with different hop count limits to a remote computer of interest. Then, on the basis of responses to the probe packets, the management apparatus produces path data that indicates a path from the management apparatus to the remote computer. The management apparatus obtains type data from the remote computer and intervening computers on the path to the remote computer. This type data indicates whether each of the remote computer and intervening computers is a physical computer or a virtual computer. When the type data indicates that the remote computer is a virtual computer, the management apparatus determines a host physical computer that is hosting the remote computer, on the basis of the type data and path data.Type: GrantFiled: March 7, 2016Date of Patent: December 4, 2018Assignee: FUJITSU LIMITEDInventors: Yuu Masuda, Hisashi Tsujide, Yoshio Oki, Yoshihiro Kimura, Toshiyuki Utsumi

Patent number: 9973388Abstract: A processor of a server information management apparatus detects an added server to a management target system. Also the processor specifies an attribute of the added server based on a communication state of the added server, first management information related to the added server, and second management information related to a communication destination server of the added server. Therefore, it is possible to precisely determine an attribute of a server which is added to a business system.Type: GrantFiled: April 14, 2015Date of Patent: May 15, 2018Assignee: FUJITSU LIMITEDInventors: Yoshio Oki, Hisashi Tsujide, Yuu Masuda, Ryuichi Kawahara, Masayuki Sakemoto, Haruhiko Tachibana, Toshiyuki Utsumi, Hiroyoshi Okada

Patent number: 9808894Abstract: A swash plate fulfils the basic properties required for a swash plate, which are stable boundary lubricating state by lubricating oil, without forming a metal spray coating layer comprising a copper type or aluminum type material on the surface of a substrate 3a forming the swash plate 3 of the swash plate type compressor as an intermediate layer. The substrate 3a of the swash plate 3 comprises a disk-shaped steel sheet formed by pressing a rolled steel sheet into a disk shape, and both surfaces of the disk-shaped steel sheet are ground. Thus, resin coating layers 10 containing fluororesin, which has superior seizure resistance, can be strongly fixed to the substrate without the need to form a metal spray coating layer on the surface of the substrate. This improves the durability of the swash plate type compressor using carbon dioxide gas as a refrigerant.Type: GrantFiled: April 14, 2014Date of Patent: November 7, 2017Assignee: NTN CorporationInventors: Naonari Tanigawa, Yoshio Oki

Patent number: 9422927Abstract: A swash plate, for a swash plate compressor, which is excellent in resistance to the occurrence of seizing in a condition where an extreme pressure is generated owing to local contact between the swash plate and a shoe which slides thereon and in a condition where lubricating oil is depleted, capable of preventing cavitation-caused erosion of a resin film when the swash plate is operated at a high surface pressure and a high speed in the presence of the lubricating oil and the swash plate compressor having the swash plate. A swash plate (3) for a swash plate compressor is so constructed that inside a housing (1) where a refrigerant is present, the refrigerant is compressed and expanded by converting a rotational motion of the swash plate (3) mounted perpendicularly and obliquely on a rotational shaft (2).Type: GrantFiled: September 21, 2011Date of Patent: August 23, 2016Assignee: NTN CORPORATIONInventors: Naonari Tanigawa, Yoshio Oki, Norikazu Muneda
