摘要： 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.

摘要： A method of manufacturing a fuel cell. An insulating member has a plurality of communication holes 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, the protrusion portion of the carbon fiber is burned and removed by Joule heat.

摘要： 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.

摘要： 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.
