Publication number: 20180018238Abstract: A file management apparatus accommodates removable storage media that store index data for use by a file system. The file management apparatus is used to read and write in these removable storage media. An information processing apparatus obtains and holds index data of each removable storage medium from the file management apparatus, and uses the index data to distinguish files recorded in the removable storage media. The file management apparatus determines the right time to make a backup of index data, based on a recovery time objective that specifies a duration of time for recovery from a system failure, and sends out a timing message indicating the determined right time. In response, the information processing apparatus causes the file management apparatus to make a backup in a specified removable storage medium.Type: ApplicationFiled: July 11, 2017Publication date: January 18, 2018Applicant: FUJITSU LIMITEDInventors: Daisuke Tomii, Ryoichi Asahi, Masaki Ikegame, Tomoya Yamashita, Tetsuya KUSANO

Patent number: 7135518Abstract: Curable compositions capable of giving a cured article excellent in weatherability and flam retardancy. (1) One of the curable compositions comprises an organic polymer having at least one crosslinkable hydrolysable silyl group and phyllosilicate. It has enhanced weatherability due to incorporation of the phyllosilicate, and has further enhanced weatherability because the bleeding of an ultraviolet absober and a light stabilizer is inhibited. (2) The other composition comprises 100 parts by weight of a urethane resin, epoxy resin, and/or modified polysulfide resin and 0.1 to 100 parts of weight of a phyllosilicate. It has enhanced weatherability due to incorporation of phyllosilicate, and has further enhanced weatherability because the bleeding of an ultraviolet absorber and a light stabilizer is inhibited.Type: GrantFiled: September 25, 2002Date of Patent: November 14, 2006Assignee: Sekisui Chemical Co., Ltd.Inventors: Akihiko Bandou, Masaya Kobayashi, Yukihiko Murayama, Takuto Ikeuchi, Tetsuya Kusano, Hideyuki Takahashi, Kouji Yamauchi, Takahiro Futamura, Satoshi Kusuda
