    • The present invention reduces exhaust emissions at startup, provides improved fuel pressure control performance in a low-load region, and detects high-pressure fuel system abnormalities. Disclosed is a high-pressure fuel system control device which includes a high-pressure pump for pressurizing fuel and discharging the pressurized fuel to a fuel rail, an injector for injecting the fuel stored in the fuel rail, and a fuel pressure sensor for measuring the pressure of the fuel stored in the fuel rail, and controls the high-pressure pump and the injector in accordance with an output generated from the fuel pressure sensor. The high-pressure fuel system control device includes a homo-elasticity coefficient estimation section for estimating a homo-elasticity coefficient of fuel in accordance with a pressure change which occurs when a fuel discharge amount of the high-pressure pump is not smaller than a predetermined value; a fuel pressure estimation section for estimating fuel pressure within the fuel rail in accordance with the homo-elasticity coefficient and control target values for the high-pressure pump and the injector; and a fuel control section for correcting an injection pulse of the injector in accordance with the fuel pressure estimated by the fuel pressure estimation section.

    • A microcomputer control section is such that, when switching is mode from a plain sheet mode to a sheetboard/OHP mode by the operation of a corresponding keys on an operation panel, the microcomputer control section changes the control temperature of an upper roller to an equivalent bit value so as to vary that control temperature from 150.degree. C. to 160.degree. C. during which time the microcomputer control section, confirming the surface temperature of an upper roller from a detection signal of a sensing section through an A/D conversion section, turns an upper lamp heater ON through a lamp control section if the surface temperature of the upper roller is below 155.degree. C. and, effecting continued confirmation of the surface temperature of the upper roller from the detection signal of the sensing section through the A/D conversion section, turns the upper lamp heater OFF through the lamp control section when the surface temperature of the upper roller increases above 160.degree. C., so that a sheetboard/OHP sheet-ready (copyable) state is displayed on a liquid-crystal display section on an operation panel.
    • 微型计算机控制部通过操作面板上的对应的键的操作切换为从普通纸模式到纸板/ OHP模式的模式时,微型计算机控制部将上辊的控制温度变更为等效 以便将控制温度从150℃改变到160℃。在此期间,微计算机控制部分通过A / D转换部分从感测部分的检测信号确认上辊的表面温度 如果上辊的表面温度低于155℃,则通过灯控制部分将上灯加热器打开,并且通过A检测部分的检测信号继续确认上辊的表面温度 / D转换部分,当上辊的表面温度升高到160℃以上时,通过灯控制部分关闭上灯加热器,使得 在操作面板上的液晶显示部分显示刨花板/ OHP薄片准备(可复制)状态。
