摘要： A lean burn internal combustion engine has a basic fuel injection amount calculated and multiplied by a lean correction factor, the resulting amount controls the air fuel ratio of the engine. The lean correction multiplied by factor is calculated from a first map based on intake pressure and engine speed. However, when the degree of opening of the throttle valve is larger than a predetermined value, a second correction map based on the degree of opening of the throttle valve and engine speed is used to obtain the lean correction factor. When the second correction map is employed, an ignition timing map based on the degree of opening of the throttle valve and engine speed is used to obtain an ignition timing; instead of the usual ignition timing, based on intake pressure and engine speed.

摘要： An air-fuel ratio control device for an engine, by which the air-fuel ratio of the air-fuel mixture supplied to the engine is changed. The device set the air-fuel ratio to a lean mixture when the engine load is lower than a set load value and predetermined set speed, and when the engine load become higher than the set load value, or the engine speed exceeds the set speed, the device switches the air-fuel ratio from a lean mixture to a rich mixture to obtain higher engine output. The set load value is varied in accordance with the engine speed such that it is reduced as the engine speed is increased.

摘要： An air-fuel ratio control device comprising a memory which stores the relationship between the degree of opening of the throttle valve and the absolute pressure in the intake passage, which pressure is produced when the engine is in a cruising state. When a difference between the blunt value of the actual absolute pressure in the intake passage and the absolute pressure stored in the memory exceeds a fixed value, the air-fuel mixture is changed from the mixture for the stoichiometric air-fuel ratio to a lean mixture.

摘要： A lean burn internal combustion engine wherein a basic fuel amount is calculated from a map based on the intake pressure and the engine speed, and a lean correction factor, which is multiplied by the basic fuel amount, is calculated from a lean map based on the intake pressure and engine speed. A second lean map based on the throttle opening and engine speed is provided for obtaining a lean correction factor when the degree of opening of the throttle valve is larger than a predetermined value. A lean sensor is provided for obtaining a signal indicating the air fuel ratio for carrying out a feedback control. The lean sensor is provided with a heater for controlling the temperature of the sensing element of the heater. A basic map for the heater power, which is based on the intake pressure and engine speed, is provided, and a correction map for the heater power is provided for reducing the heater power from the value obtained from the basic map when the lean map based on the intake pressure and engine speed is employed for obtaining the lean air-fuel mixture, to prevent thermal damage to the sensor element.

摘要： In an internal combustion engine, a vibration period and a vibration amplitude are measured and the detected vibration period is compared with a natural vibration period prestored in accordance with a driving condition of the vehicle. If the detected vibration period is equal to the natural vibration period under the driving condition at which the vibration period is detected, it is determined that surging due to a torque variation of the engine is occurring. In this condition, the torque variation is controlled to be a predetermined value by increasing an air-fuel ratio or decreasing an amount of EGR when the detected vibration amplitude is smaller than a predetermined value, and the torque variation is controlled to a predetermined value by decreasing an air-fuel ratio or increasing an amount of EGR when the detected vibration amplitude is larger than a predetermined value, and accordingly, the driveability and emission rate are improved.

摘要： A device for determining an activated condition of the oxygen sensor of a lean sensor for an electric-controlled fuel injection internal combustion engine. When the engine is under a fuel cut operation, the output level from the oxygen sensor is compared with a first predetermined threshold level or with a second predetermined threshold level which is lower than the first threshold level. A determination of the activated condition of the oxygen sensor is obtained when the output level from the oxygen once exceeds the higher first level, or when the output level from the oxygen sensor consecutively exceeds the higher first level twice, whereby a positive and quick determination of the activated condition of the oxygen sensor can be obtained.

摘要： When a user commands a microprocessor, using a remote control, to output information about a video and audio signal output device itself to a monitor device, the microprocessor superimposes, on video signals decoded by a decoder, video signals of a terminal connection information image for displaying, on the monitor device, color images corresponding to output signals from respective output terminals of red (R), green (G) and blue (B) in a VGA terminal or a BNC terminal so as to form and output combined video signals to the monitor device. Thus, e.g. if the monitor device has multiple video signal input terminals for inputting output signals from the respective output terminals of R, G and B, and if no signal is input from one of the input terminals, the user can confirm the input terminal, from which no signal is input, by just watching the screen of the monitor device without confirming the actual connection of the input terminals.

摘要： Defects in element forming regions on which memory cells of a non-volatile memory are formed are to be diminished to reduce leakage current. End portions of element forming regions with non-volatile memory cells formed thereon are extended a length D by utilizing the region which underlies a dummy conductive film, whereby a stress induced from an insulating film which surrounds the element forming regions is concentrated on the extended region. As a result, defects do not extend up to the regions where memory cells are formed and therefore it is possible to reduce leakage current in the memory cells.

摘要： A TV receiver comprises: a tuner connected to a unidirectional antenna or a smart antenna; a reception control unit for outputting, to the tuner, a channel control signal to command a channel, and outputting, to the smart antenna, a receiving direction control signal to command a receiving direction; and an antenna selection switch for a user to select the either antenna. The reception control unit switches its control mode between a unidirectional antenna mode and a smart antenna mode. In the unidirectional antenna mode, the reception control unit outputs a channel control signal to the tuner. In the smart antenna mode, the reception control unit outputs the channel control signal and the receiving direction control signal to the tuner and the smart antenna, respectively, for controlling the TV signal reception. This TV receiver can properly switch the antenna control mode, depending on the kind of antenna selected by the user.
