摘要:
Around a heat roller, a center thermistor (20c) as a first temperature sensor is placed within the range of ±45° from a portion where maximum heat is generated by an IH coil, and a front thermistor (20f) as a second temperature sensor is placed within the range of ±45° from a portion where minimum heat is generated by the IH coil. A main CPU (201) performs fixing control on the basis of sensing temperatures from these two thermistors (20c, 20f). This can prevent an increase in the cost and uniformize the heat distribution of a fixing roller.

摘要:
There is provided a control apparatus for a cylinder injection internal combustion engine which suppresses fuel pulsation caused by cam phase deviation and thereby prevents internal combustion engine exhaust deterioration, so that the reliability of a high-pressure fuel system using a high-pressure fuel pump is improved. The control apparatus for a cylinder injection internal combustion engine includes a high-pressure fuel pump that raises the pressure of fuel and discharges the fuel to a fuel rail, and a fuel pressure sensor that detects a pressure of fuel stored in the fuel rail. The control apparatus controls the high-pressure fuel pump based on the fuel pressure detected by the fuel pressure sensor. The control apparatus further includes a cam phase estimation means for estimating a phase of a cam shaft of the internal combustion engine which drives the high-pressure fuel pump, and based on the phase estimation value calculated by the cam phase estimation means, corrects the amount of controlling the high-pressure fuel pump.

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.

摘要:
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.
