Publication number: 20090090435Abstract: A process for producing a magnetic powder which is sufficiently reduced in core losses such as iron loss and hysteresis loss and has sufficient strength; and a process for producing a dust core. The process for magnetic powder production comprises using a magnetic-material powder produced by water atomization as a raw powder and subjecting the powder to spheroidizing in which a mechanical impact is applied to the powder to spheroidize the powder particles. After the spheroidizing, the powder is subjected to a grain enlarging treatment in which the powder is annealed at a temperature not lower than the austenite transformation point. The process for dust core production comprises compacting the magnetic powder thus produced.Type: ApplicationFiled: May 29, 2007Publication date: April 9, 2009Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, FINE SINTER CO., LTD.Inventors: Eisuke Hoshina, Toshiya Yamaguchi, Kazuhiro Kawashima

Patent number: 5590272Abstract: A disk controller itself performs the serial inspection process in the following way. It divides a track into a current track group directly available for an external computer and a spare track group available for the disk controller independently of the external computer before registering the groups in it. It also automatically selects a track available in the spare track group as an alternative track. It further copies to the alternative track data recorded on a current track to be inspected. In turn, the disk controller writes a test pattern on the current track. With this, it detects a defect position on a surface of a recording medium of the current track. It also registers the defect position detected on the surface of the recording medium to the current track. It further copies the data having been copied on the alternative track to the current track.Type: GrantFiled: December 21, 1992Date of Patent: December 31, 1996Assignee: Hitachi, Ltd.Inventors: Tomohiro Murata, Kenzo Kurihara, Kazuhiro Kawashima, Mitsuaki Niida
