Patent number: 7167950Abstract: The present invention carries out cache management in such a manner that the management region required for cache management does not increase, and neither does the performance decline. It is possible to combine use of both a hierarchical directory method and a hash directory method, in order to manage cache data. In a hierarchical directory method, the desired data is retrieved by referring to respective tables T1 to T7, in succession. In a hash directory method, the desired data is reached by referring to a hash table T10 and tables T4 to T7. Access conflicts between the respective methods are avoided by using the EDEV number and a portion of the VDEV number for a hash key. By combining use of both of these methods, it is possible to respond to cases where the storage capacity of the storage system has been increased, without having to raise the management region, and without causing a decline in performance.Type: GrantFiled: May 21, 2004Date of Patent: January 23, 2007Assignee: Hitachi, Ltd.Inventors: Takashi Sakaguchi, Sachiko Hoshino, Yasuyuki Nagasoe

Patent number: 6488309Abstract: An airbag module has a housing, a multiple stage gas generator, a gas bag and a gas bag cover. In an inoperative state the gas bag lies in a folded condition next to the gas generator. Only one gas bag layer extends over the generator so that after ignition of the gas generator, the gas bag is drawn successively out from a housing by the gases discharged from the generator. The gas bag cover is formed so that after opening the gas bag cover increasingly greater forces are required to unfold the gas bag from a predetermined time point onwards and so that an outer part of the gas bag only unfolds in the event of the greater forces.Type: GrantFiled: June 6, 2001Date of Patent: December 3, 2002Assignee: Takata-Petri AGInventors: Axel Malczyk, Falk Ose, Takashi Sakaguchi
