    • An authentication system determines if a counterfeit ineligible unit is installed in a main device. When connected with a battery pack, a notebook PC generates and combines a random number and a function determination signal using a signal combining unit and transmits same to the battery pack. A first function calculation unit calculates the function of the random number. The battery pack has a signal separation unit to separate the combined signal into the random number and function determination signal, and a second function calculation unit to calculate the function of the random number for transmitting back to the notebook PC. A comparison unit compares the calculation results by the first and second function calculation units to determine whether the connected battery pack is an authorized one and denies connection if the pack is an unauthorized one.
    • 验证系统确定假设的不合格单元是否安装在主设备中。 当与电池组连接时,笔记本电脑使用信号组合单元产生并组合随机数和功能确定信号,并将其发送到电池组。 第一函数计算单元计算随机数的函数。 电池组具有信号分离单元,用于将组合信号分离成随机数和功能确定信号;以及第二功能计算单元,用于计算用于发送回笔记本PC的随机数的功能。 比较单元将第一和第二功能计算单元的计算结果进行比较,以确定所连接的电池组是否是授权的,并且如果该组件是未授权的,则拒绝连接。

    • A battery has an organic electrolyte, a negative electrode having at least one metal out of alkaline metal and alkaline metal alloy, and a positive electrode including a conductive core having at least one metal out of porous metal plate and metal mesh, wherein an active material covers the core. At least a part of one side of the core is exposed from the active material at a position confronting the negative electrode, and the width of narrowest part of the metal is greater than the thickness of the negative electrode. In this constitution, the discharge reaction is delayed in the exposed portion of the core of the positive electrode. By this delay in discharge reaction, the electric connection of the negative electrode is maintained up to the end of discharge. Hence, voltage drop at the end of discharge is suppressed. As a result, the battery having an excellent discharge capacity up to the end of the discharge is obtained.
    • 电池具有有机电解质,具有碱金属和碱金属合金中的至少一种金属的负极和包含导电芯的正极,所述导电芯具有多孔金属板和金属网中的至少一种金属,其中活性物质 涵盖核心。 核心的一侧的至少一部分在与负极相对的位置处从活性物质露出,金属的最窄部分的宽度大于负极的厚度。 在该结构中,放电反应在正极的芯的露出部分延迟。 由于放电反应的这种延迟,负极的电连接被维持直到放电结束。 因此,放电结束时的电压降被抑制。 结果,获得了直到放电结束时具有优异的放电容量的电池。

    • A method of attaching a battery cell in an apparatus acted upon by centrifugal force avoids an extreme decline in discharge capacity of the battery cell when acted upon by the centrifugal force. The battery, of the type including a positive polarity material and a negative polarity material which are placed in opposition in a thickness direction of a battery case with an intervening separator disposed therebetween, and a liquid electrolyte packed inside the battery case, is mounted in the apparatus, oriented such that a negative polarity material side of the battery cell faces generally in a direction in which the centrifugal force acts on the apparatus, and an angle of inclination of a thickness direction of the battery cell is within a range of 0 to about 60 degrees relative to the direction of the centrifugal force.
    • 将电池单元安装在由离心力作用的装置中的方法避免了由离心力作用时电池单元的放电容量的极大下降。 包括正极性材料和负极性材料的类型的电池被安装在电池壳体的厚度方向上,并且在电池壳体之间设置有介于其间的隔板,并且包含在电池壳体内的液体电解质 装置,使得电池单元的负极性材料侧大致面对离心力作用于设备的方向,并且电池单元的厚度方向的倾斜角度在0至约的范围内 相对于离心力方向60度。
