    摘要： An air-fuel ratio control apparatus is applied to an internal combustion engine including a variable lift mechanism which changes a lift amount of an intake valve. An oxygen sensor, which outputs a signal indicating an oxygen concentration in exhaust gas, is provided downstream of an exhaust gas purification catalyst in an exhaust passage of the internal combustion engine. Air-fuel ratio control is performed to correct the fuel injection amount command value using the correction amount that is set based on the value output from the oxygen sensor. The relationship among the deviation of the correction amount from its reference value, the learned small lift value, the learned medium lift value, and the lift amount is learned. The learned deviation value is calculated based on the lift amount, using the learned relationship. Then, the fuel injection amount command value is corrected by the correction amount including the calculated learned deviation value.

    摘要： If it is determined that an engine has been started, an engine coolant temperature is detected. If the engine coolant temperature is equal to or lower than a threshold value, the catalyst quick warm-up control is started to retard ignition timing, and a signal indicating a command to increase an operate angle is transmitted to a VVLA controller. When a VVT hydraulic pressure is increased to a predetermined value, a signal indicating a command to decrease the operate angle is transmitted to the VVLA controller, and a signal indicating a command to advance open timing of an intake valve is transmitted to a VVT controller so that the open timing of the intake valve is not changed. If the engine coolant temperature is equal to or higher than a threshold value, the catalyst quick warm-up control ends, and the ignition timing is returned to normal timing.

    摘要： A semiconductor device capable of suppressing a threshold shift and a manufacturing method of the semiconductor device. On a high dielectric constant insulating film, a diffusion barrier film for preventing the diffusion of metal elements from the high dielectric constant insulating film to an upper layer is formed. Therefore, the diffusion of the metal elements from the high dielectric constant insulating film to the upper layer can be prevented. As a result, a reaction and bonding between the metal elements and a Si element in a gate electrode can be suppressed near a boundary between an insulating film and the gate electrode.
