    • A color image pickup apparatus includes a photo-to-electric conversion section subjected to progressive scanning. A first delay circuit defers an output signal of the photo-to-electric conversion section. A first adder combines the output signal of the photo-to-electric conversion section and an output signal of the first delay circuit. A second delay circuit defers the output signal of the first delay circuit. A second adder combines the output signal of the photo-to-electric conversion section and an output signal of the second delay circuit. A third delay circuit defers an output signal of the first adder. A first subtracter implements subtraction between the output signal of the first adder and an output signal of the third delay circuit. A fourth delay circuit defers an output signal of the second adder. A second subtracter implements subtraction between the output signal of the second adder and an output signal of the fourth delay circuit. A first sign change circuit inverts a sign of an output signal of the first subtracter. A first selector periodically and alternately selects one of the output signal of the first subtracter and an output signal of the first sign change circuit. A second sign change circuit inverts a sign of an output signal of the second subtracter. A second selector periodically and alternately selects one of the output signal of the second subtracter and an output signal of the second sign change circuit. Two different color-difference signals are generated in response to an output signal of the first selector and an output signal of the second selector.

    • A blow-by gas passage abnormality detecting system for an internal combustion engine detects, only under the condition that the running state of the engine is idle, a leakage of a blow-by gas coming from a blow-by gas passage for returning the blow-by gas produced in the engine to an intake passage, on the basis of a parameter varying with a change in the air flow to be sucked into the engine. The abnormality such as leakage or clogging in the blow-by gas passage is detected if the ISC opening of an idle speed control valve measured as a load amount at an idle time of the engine is smaller than a predetermined value. Alternatively, the abnormality may be detected by detecting the blow-by gas pressure in the blow-by gas passage downstream of a PCV valve by a gas pressure sensor.
    • 用于内燃机的窜气通道异常检测系统仅在发动机的行驶状态怠速的情况下检测来自用于返回吹气的窜气通道的窜气的泄漏 - 基于随着要吸入发动机的空气流的变化而变化的参数,在发动机中产生的气体到进气通道。 如果在发动机空转时测量为负载量的怠速控制阀的ISC开度小于预定值,则检测到窜气通道中的泄漏或堵塞等异常。 或者,可以通过气体压力传感器检测PCV阀下游的窜缸气体通道中的窜气压力来检测异常。
