  • Publication number: 20130177791
    Abstract: An electrical storage apparatus 1 includes a plurality of battery modules 10 and cooling passages A, B for cooling each of the battery modules 10. The cooling passage A is configured so as to cool all battery modules 10 mounted in the electrical storage apparatus 1 at all times during charging. The cooling passage B is configured so as to cool only a new battery module 10a as a replacement during charging. This enables the battery module 10a having a temperature during charging higher than that of a battery module 10 yet to be replaced to be subject to forced cooling, thereby preventing performance of the battery module 10a from being degraded.

  • Patent number: 8135991
    Abstract: 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.

  • Publication number: 20110048225
    Abstract: 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.
