    • An antiferroelectric liquid crystal composition having a chiral smectic CA* phase composed by blending liquid crystal composition-constituting compounds having the same direction of inclination of optic axis produced by application of an electric field and/or comprised of a mixture of two enantiomers of a liquid crystal material; one having the stereosense (+) and the other having the stereosense (−). The stereosense is defined so that, when the molecule is viewed so that the bond between the core group and the asymmetric carbon is behind the asymmetric carbon atom, the stereosense is (+) if the remaining three groups (or atoms) are arranged clockwise in order of length of the groups (or, if the groups are the same length, in order of their volume), and the stereosense is (−) if the groups are arranged counter clockwise.

    • A battery capacity measuring device in accordance with the present invention has a fully-charged state detector (80e), a detected current integrator (80a), a divider (80b), and a corrector (80c) incorporated in a microcomputer (80). The fully-charged state detector detects that a battery is fully charged. The detected current integrator integrates current values that are detected by a current sensor during a period from the instant the battery is fully charged to the instant it is fully charged next. The divider divides the integrated value of detected current values by the length of the period. The corrector corrects a detected current using the quotient provided by the divider as an offset. Furthermore, a remaining battery capacity calculating system comprises a voltage detecting unit (50), a current detecting unit (40), an index calculating unit, a control unit, and a calculating unit. The voltage detecting unit detects the voltage at the terminals of a battery. The current detecting unit detects a current flowing through the battery. The index calculating unit calculates the index of polarization in the battery according to the detected current. The control unit controls the output voltage of an alternator so that the index of polarization will remain within a predetermined range which permits limitation of the effect of polarization on the charged state of the battery. When the index of polarization remains within the predetermined range, the calculating unit calculates the remaining capacity of the battery according to the terminal voltage of the battery, that is, the open-circuit voltage of the battery.
    • 根据本发明的电池容量测量装置具有完全充电状态检测器(80e),检测电流积分器(80a),分配器(80b)和结合在微型计算机(80)中的校正器(80c))。 完全充电状态检测器检测到电池已充满电。 检测到的电流积分器将从电池完全充电到其下一次完全充电的时间段内的电流传感器检测到的电流值进行积分。 分频器将检测到的当前值的积分值除以周期的长度。 校正器使用由分频器提供的商作为偏移来校正检测到的电流。 此外,剩余电池容量计算系统包括电压检测单元(50),电流检测单元(40),索引计算单元,控制单元和计算单元。 电压检测单元检测电池端子处的电压。 电流检测单元检测流过电池的电流。 索引计算单元根据检测到的电流来计算电池中的偏振指标。 控制单元控制交流发电机的输出电压,使得偏振指标将保持在预定范围内,这允许限制极化对电池充电状态的影响。 当偏振指数保持在预定范围内时,计算单元根据电池的端子电压,即电池的开路电压来计算电池的剩余容量。

    • According to a manufacturing method for a fuel cell, an insulating member having a plurality of communication holes therein is disposed on a side of a gas diffusion layer, which is formed by stacking a layer made of a carbon fiber and a water-repellent layer, where the water-repellent layer is provided, the gas diffusion layer and the insulating member are sandwiched by a pair of electrodes, and a pair of contact pressure plates are disposed on respective rear surfaces of the pair of electrodes so as to sandwich the pair of electrodes so that the gas diffusion layer is pressurized by the pair of contact pressure plates. When a voltage is applied to the pair of electrodes while maintaining the pressurized state, an electric current flows through a protrusion portion of a carbon fiber which comes in contact with the electrode on the water-repellent layer side via the communication holes of the insulating member, so that the protrusion portion of the carbon fiber is burned and removed by Joule heat. When it is detected that no electric current flows between the electrodes, application of a voltage to the pair of electrodes is stopped, and the pressure in the pressurized state is decreased to a normal pressure state.
    • 根据燃料电池的制造方法,具有多个连通孔的绝缘部件设置在通过层叠由碳纤维和拒水层构成的层而形成的气体扩散层的一侧, 在其中设置防水层的情况下,气体扩散层和绝缘构件被一对电极夹持,并且一对接触压力板设置在该对电极的各个后表面上,以夹持该对电极 电极,使得气体扩散层被一对接触压力板加压。 当在保持加压状态的同时对一对电极施加电压时,电流通过绝缘构件的连通孔流过与斥水层侧的电极接触的碳纤维的突出部分 ,使得碳纤维的突出部分通过焦耳热被燃烧和去除。 当检测到电极之间没有电流流动时,停止向一对电极施加电压,并且加压状态下的压力降低到正常压力状态。
