    • In a hybrid vehicle of the invention, when a voltage level E of a low-voltage battery exceeds a preset alert reference value Eth1 (step S115), fueling control activates a negative pressure pump with a preset amount of power consumption for standard fuel vapor treatment (step S125). When the voltage level E of the low-voltage battery exceeds a low charge reference value Elow but is not higher than the preset alert reference value Eth1 (steps S115 and S120), the fueling control activates the negative pressure pump with a smaller amount of power consumption (step S130). When the voltage level E of the low-voltage battery is not higher than the low charge reference value Elow (step S120), the fueling control inactivates the negative pressure pump (step S135). Such control enables at least a voltage of the low charge reference value Elow to be reserved in the low-voltage battery even after regulation of internal pressure of a fuel tank. This effectively prevents an insufficiency of electrical energy by the regulation of the internal pressure of the fuel tank.
    • 在本发明的混合动力车辆中,当低压电池的电压电平E超过预先设定的警报基准值Eth1(步骤S115)时,加油控制以标准燃料蒸气处理的预定的功耗量激活负压泵 (步骤S125)。 当低压电池的电压电平E超过低电荷参考值Elow但不高于预设警报参考值Eth1(步骤S115和S120)时,加油控制以较小的功率量激活负压泵 消耗(步骤S130)。 当低压电池的电压电平E不低于低充电基准值Elow(步骤S120)时,加油控制使负压泵失活(步骤S135)。 这种控制使得即使在调节燃料箱的内部压力之后,也能够将低电荷参考值Elow的至少一个电压保留在低电压电池中。 这通过调节燃料箱的内部压力来有效地防止电能不足。

    • An electronic watermark data insertion apparatus comprises an insertion information memory (39) for preliminarily storing insertion information for designating electronic watermark data to be inserted block by block and an electronic watermark data insertion unit (33) for inserting, on the basis of the insertion information, the designated electronic watermark data from an electronic watermark data table (37) in a quantized image block by block. An electronic watermark data detection apparatus comprises an electronic watermark date extracting unit (45) for extracting the image data having a biased frequency region projecting in dependency on the inserted electronic watermark data block by block and an electronic watermark data detection unit (50) for calculating a statistical similarity between the extracted data and the electronic watermark data stored in an electronic watermark data table (48). An electronic watermark data accumulator (51) accumulates the statistical similarity for a predetermined time interval to produce an accumulated addition result which is reset after the elapse of the predetermined time interval or when the accumulated addition result exceeds the a predetermined threshold value. A determining unit (52) determines that the electronic watermark data is detected when the accumulated addition result exceeds the predetermined threshold value.

    • The A/D converter has first and second PPDC circuits (pulse-phase-difference coding circuits). The first PPDC circuit performs A/D conversions on the reference voltage and on the voltage signal amplified by an amplifier in an alternating sequence, the amplifier using the reference voltage as a potential base thereof. The second PPDC circuit performs A/D conversions always on the reference voltage. The A/D-converted data set of the voltage signal outputted from the first PPDC circuit is corrected depending on the difference between the A/D-converted data set of the reference voltage outputted from the second PPDC circuit when the first PPDC circuit A/D-converts the reference voltage and the A/D-converted data set of the reference voltage outputted from the second PPDC circuit when the first PPDC circuit A/D-converts the voltage signal.
