Patent number: 8135991Abstract: A flash memory is made to store a same boot program in a plurality of blocks in it. When a flash memory controller receives an access command for accessing the storage region storing the boot program from a CPU (Step S101), it outputs the read out data to the CPU only when the corresponding block is not faulty according to the determination (Steps S105, S106) made on the basis of the ECC contained in the data read out from the corresponding page and the determination (Step S109) made on the basis of the block information also contained in the data read out from the corresponding page. If, on the other hand it is determined that the block is faulty, the flash memory controller reads out the boot program stored in the next block (Steps S106, S103) and determines once again that the block is faulty or not faulty.Type: GrantFiled: January 27, 2005Date of Patent: March 13, 2012Assignee: Sony CorporationInventors: Yoshito Katano, Tadashi Yoshida, Kazuhiro Sako

Publication number: 20110048225Abstract: On a protrusion-formation portion of a rod guide, there are provided a first annular protrusion for supporting a radially outer side of a lid body and a second annular protrusion for supporting a radially inner side of the lid body. Accordingly, when an upper end side of an outer cylinder is caulked, the first annular protrusion provided to the rod guide is allowed to sandwich and fix the radially outer side of the lid body between the first annular protrusion and the caulked portion. Further, although the lid body is strongly pressed to the rod guide with use of a presser at the time of caulking the upper end side of the outer cylinder, a pressing force acting onto the lid body can be received by the second annular protrusion. As a result, the lid body is prevented from being permanently deformed. With this structure, the lid body can be formed to have a small thickness dimension.Type: ApplicationFiled: August 31, 2010Publication date: March 3, 2011Inventors: Tadashi YOSHIDA, Masahiro Ashiba
