    • In the nonaqueous electrolyte secondary battery, the positive electrode active material is composed of a mixture of a lithium-cobalt composite oxide containing at least both zirconium and magnesium, and a lithium-manganese-nickel composite oxide containing at least both manganese and nickel. The nonaqueous electrolyte includes fluoroethylene carbonate and dimethyl carbonate as a nonaqueous solvent and further includes an additive expressed by General Formula (1), which having a capability to form an SEI surface film, and a higher oxidation resistance than that of VC. Thus, the negative electrode active material is unlikely to react with the organic solvent. Therefore, decomposition of the organic solvent is suppressed. Thus the battery having a long cycling life even when it is charged at a positive electrode charging potential of 4.4 to 4.6 V based on lithium and having a high residual capacity after storage at high temperature in a charged state is provided.
    • 在非水电解质二次电池中,正极活性物质由至少含有锆和镁两者的锂 - 钴复合氧化物和至少含有锰和镍两者的锂 - 锰 - 镍复合氧化物的混合物构成。 非水电解质包括氟代碳酸亚乙酯和作为非水溶剂的碳酸二甲酯,并且还包括具有形成SEI表面膜的能力和比VC更高的抗氧化性的由通式(1)表示的添加剂。 因此,负极活性物质不可能与有机溶剂发生反应。 因此,有机溶剂的分解被抑制。 因此,电池具有长的循环寿命,即使在基于锂的正极充电电位为4.4〜4.6V下充电,并且在充电状态下在高温下保存后具有高剩余容量。

    • Second transistors working as temperature-monitoring elements are disposed in the vicinity of the respective first transistors (HBT cells) connected in parallel to amplify an RF signal and at positions where their thermal environments are substantially the same. Each of the second transistors is connected between its collector and its base to thereby constitute a diode through which the current rises as the temperature increases. The collectors of the second transistors are connected with a DC power supply through respective first resistors, and their emitters are grounded through respective second resistors. Further, their bases are connected with the bases of the respective first transistors through respective first inductors.
