    • In order to protect the user security data, provided is a memory card capable of preventing the data leakage to a third party not having the access authority by imposing the limitation on the number of password authentications and automatically erasing the data. In a system comprised of a multimedia card and a host machine electrically connected to the multimedia card and controlling the operations of the multimedia card, a retry counter for storing the number of password authentication failures is provided and the upper limit of the number of failures is registered in a register. When passwords are repeatedly entered once, twice, . . . and n times and the retry counter which counts the entries reaches the upper limit of the number of failures, the data is automatically erased so as not to leave the data in the flash memory.

    • A method for manufacturing a sealed battery according to one embodiment of this invention includes a first step of using an outer can 15 having an opening, and a sealing plate 16 having a flange provided with a groove 22 around or on a part of a fitting face of the sealing plate 16 with the outer can 15, and inserting the sealing plate 16 into the opening of the outer can 15 so that a top face of the outer can 15 is approximately flush with a top face of the flange of the sealing plate 16, and a second step of welding together the outer can 15 and the sealing plate 16 by radiating a high energy ray to the fitting portion therebetween. The invention thus makes it possible to provide a method for manufacturing a sealed battery in which a weld formed by welding a sealing plate fitted into an opening of an outer can of a battery with a laser or other high energy rays has a large breaking strength, and a sealed battery manufactured thereby.

    • In technology for enabling the replacement of part of an operating program of a controller by a modified program on a nonvolatile memory, the present invention prevents tampering and leak of storage information within the nonvolatile memory and the controller. At power-on reset, an encrypted alternative program, if present, is transferred from a nonvolatile memory to a volatile memory, and decrypted when actually executed. A long wait is not required until data processing by a data processor is enabled after the exit from the reset processing. Since the alternative program once decrypted is held in the volatile memory so as to be reusable, it does not need to be decrypted each time it is executed. Since the alternative program is encrypted, even if the nonvolatile memory is physically separated from the controller to illegally dump the alternative program, it is difficult to analyze the data.
    • 本发明在非易失性存储器中通过修改程序使控制器的一部分操作程序更换的技术中,防止非易失性存储器和控制器内存储信息的篡改和泄露。 在上电复位时,加密的替代程序(如果存在)从非易失性存储器传输到易失性存储器,并在实际执行时进行解密。 在复位处理退出后,数据处理器的数据处理才能进行长时间的等待。 由于一旦解密的替代程序被保存在易失性存储器中以便可重用,因此在每次执行时不需要被解密。 由于替代程序被加密,即使非易失性存储器在物理上与控制器分离以非法地转储替代程序,因此难以分析数据。

    • A sealed cell having a safety mechanism is provided. The safety mechanism has a non-resealable valve structure formed in a sealing plate that seals the cell. The valve structure is broken as soon as the internal pressure reaches or exceeds a predetermined value so as to permit the internal gas to be released outside. The valve structure has at least one dome protruding toward the interior of the cell, which in turn has at the periphery thereof a break groove for facilitating the breakage of the valve structure. This makes the valve structure highly responsive to the internal pressure and causes to form a break-opened orifice of a sufficient area at the time of operation in response to the increased internal pressure. The valve structure is not unnecessarily broken by the impacts of, for example, dropping. As a result, the safety of the sealed cell is significantly improved.
    • 提供具有安全机构的密封电池。 安全机构具有密封电池的密封板中形成的不可重新密封的阀结构。 一旦内部压力达到或超过预定值,阀结构就会断裂,从而允许内部气体释放到外部。 阀结构具有朝向电池内部突出的至少一个圆顶,其圆周上还具有用于促进阀结构断裂的断裂凹槽。 这使得阀结构对内部压力具有高度响应性,并且导致响应于增加的内部压力而在操作时形成足够面积的断开孔。 阀结构不会由于例如落下的影响而不必要地破坏。 结果,密封电池的安全性显着提高。
