Abstract: A mold is provided which is capable of producing a sound fiber-reinforced composite article utilizing a die-casting process. A cavity in the mold includes a composite article forming area in which a formed product of fiber is located, a molten metal storing area located adjacent the composite article forming area to fill a molten metal into the formed product of fiber, and a molten metal flow slackening area for reducing the turbulent flow of the molten metal from gates to introduce it to the molten metal storing area. Thus, the flow of the molten metal introduced into the molten metal storing area, is brought into a substantially laminar flow state, so that the inclusion of air in the molten metal flow is inhibited. Therefore, the molten metal in the molten metal storing area can be smoothly filled into the formed product of fiber under pressure.

Abstract: In accordance with an output of an oxygen concentration sensor 16, an air-fuel ratio correction coefficient KO2 is periodically set to values respectively corresponding to a leaner air-fuel ratio and a richer air-fuel ratio with respect to a theoretical air-fuel ratio (steps S22 to S28). Based on an output of an oxygen concentration sensor 16, a NOx amount counter nNOx is counted up, and the amount of NOx absorbed by a NOx absorbent catalyst is estimated. When the value of the NOx amount counter nNOx reaches a preset value NSAT, an air-fuel ratio of an air-fuel mixture is set to be further richer than the richer air-fuel ratio.

Abstract: In a steering control system for a motor vehicle, the magnitude of the steering assist torque is reduced from a normal value by a value depending on the ratio of the steering angle to a maximum permissible steering angle which is determined according to the frictional coefficient between the road surface and the road wheels so that excessive steering, which may otherwise occur on a slipper road surface, can be avoided. Additionally, the value by which the steering assist torque is reduced is increased with an increase in the steering speed so that a certain damping effect may be achieved in the system. This is particularly beneficial in preventing any ill effect which may arise when the steering wheel has a large mass of inertia, for instance by being equipped with an air bag system.
