摘要： An IC power protection circuit functions as a surge protection circuit and reverse connection protection circuit. The IC power protection circuit includes an error amplification circuit, positioned and integrated within an integrated circuit and a transistor positioned as a stand-alone element that is separate from the integrated circuit. The integrated circuit includes a sensor signal processing circuit that processes a signal of a sensor. A transistor protects the integrated circuit against a surge voltage from a battery terminal. A resistor is positioned between an output terminal of an error amplifier and a base terminal of the transistor to provide reverse connection protection. Another resistor is connected between a ground and a connection point between the above resistor and the output terminal to provide overvoltage protection for the integrated circuit. A starting resistor is connected between a collector and base of the transistor.

摘要： A thermal flow sensor which is fabricated at a low cost and has improved reliability. Over a cavity (7) formed in a semiconductor substrate (2), at least a heating resistance (4) is formed near the center of the cavity with an electrical insulation film interposed between the heating resistance and the cavity. The temperature (Th) of the heating resistance (4) is controlled to be higher than the medium temperature (Ta) by a constant temperature ({Th=Th−Ta). A distance (Ws) in the direction of airflow from an upstream end of the heating resistance (4) to an upstream end of the electrical insulation film lying over the cavity and the constant temperature (ΔTh) satisfy the following relationship: ΔTh/Ws≦800 (° C./mm) Thus, a thermal flow sensor is provided which can prevent deposition of floating fine particles, such as carbon particles, caused by the thermophoretic effect, can be fabricated at a low cost, and has high reliability.

摘要： An exhaust recirculation control system of the internal combustion engine computes an oxygen concentration in total intake air containing recirculation exhaust gas in a cylinder and the ratio between an oxygen quantity in the total intake air and a fuel injection quantity (oxygen quantity/fuel injection quantity ratio). The computed values are compared with target values which are pre-set according to engine operating conditions and, based on the result of the comparison, at least an EGR valve or a fuel injection quantity. In order to perform such a control with high accuracy, a correcting means corrects a recirculation exhaust gas mass flow signal from a gas mass flowmeter on the basis of a predicted exhaust gas component concentration. And, by using the corrected recirculation exhaust gas mass flow, oxygen concentration in total intake air containing the recirculation exhaust gas in the cylinder and the ratio between the oxygen quantity in the total intake air and the fuel injection quantity (target oxygen quantity/fuel injection quantity ratio) are computed to perform EGR control.

摘要： A thermal type air flow meter that makes it possible to precisely and easily determine whether a sensor element is a non-defective or a defective by screening is provided. First and second diaphragm sections composed of an electrical insulating film are formed in a semiconductor substrate. A heating resistor and a resistor for intake air temperature sensor are disposed on them to obtain a sensor element for thermal type air flow meters. The length of the short sides W1 of the rectangular first diaphragm section is made substantially equal to the length of the short sides of the second diaphragm section rectangular as well. Thus, the pressures applied to each of the diaphragm sections are substantially identical with each other in pressurization during screening.

摘要： A hot-wire type air flow meter for an internal combustion engine has an exothermic resistor film provided on a thin portion formed on a silicon substrate and a control circuit for controlling a voltage to be applied to the resistor film or a current to be supplied. The resistor film is arranged in a suction pipe of the internal combustion engine and heat is emitted to an air through the resistor film. In the case where a liquid droplet is deposited onto the resistor film, the control circuit controls the applied voltage to a value smaller than a voltage which is applied to the resistor film at the time of measuring a maximum specified measuring range or controls the supply current to a value smaller than a current flowing in the resistor film at the time of measuring the maximum specified measuring range.

摘要： A fixing apparatus includes a fixing roller, a heat roller, a seamless fixing belt, a pressure roller, a supporting roller, and a pressure applying member. The heat roller includes a fixing heat source. The seamless fixing belt is extended between the fixing roller and the heat roller. The pressure roller pushes the fixing roller via the fixing belt to form a second fixing-process area. The supporting roller contacts inside the fixing belt and winds the fixing belt around a surface of the pressure roller to form a first fixing-process area upstream of and next to the second fixing-process area. The pressure applying member applies a pressure to the heat roller in a direction opposite to an ejection of the recording sheet from the second fixing-process area to adjust a fixing pressure of the first fixing-process area.
