摘要： A fuel injection control apparatus includes a computing unit that calculates a pulse width for a pulse signal which drives the valve of a fuel injector, based on the operational state of the internal combustion engine and fuel pressure detected by a fuel pressure sensor. After a valve-opening command has turned on and a high valve-opening current has been supplied to open the fuel injector valve, a fuel injector driving signal waveform command unit discharges the current and supplies a small hold current Ih2 to maintain the injector's valve-open state. After the elapse of a predetermined rapid-discharge starting time from the turn-on of the valve-opening command, the fuel injector driving signal waveform command unit rapidly discharges the current until the hold current Ih2 has been reached.

摘要： To provide a fuel injection control apparatus capable of reducing the minimum quantity of fuel injection without reducing the maximum quantity of injection.For fuel injector valve opening, a driving circuit 56 supplies an electric current from a high-voltage power supply VH to the fuel injector 53, then after valve opening, switches the high-voltage power supply VH to a low-voltage power supply LV, and retains the open state of the valve. A microcomputer 57 is adapted such that for opening the valve of the fuel injector, the microcomputer, after supplying the current from the high-voltage power supply to the injector 53, discharges the current rapidly for a decrease below a first current level Ihold1 at which the open state of the valve cannot be retained, and then controls the supply current to the injector 53 so as to supply a current of a second current level Ihold2 at which the open state of the valve can be retained.

摘要： A mask is formed of an upper part, a lower part opposing the upper part and having a form generally similar to that of the upper part, and a connection part for connecting a lower edge of the upper part and an upper edge of the lower part. The left edges of the upper and lower parts are joined, and the right edges of the upper and lower parts are joined, while the upper edge of the upper part and the lower edge of the lower part are not joined. The connection part has a folding portion located between the upper part and the lower part, and is bent relative to the lower edge of the upper part and the upper edge of the lower part, so that the connection part does not protrude outwardly over the lower edge of the upper part and the upper edge of the lower part. Breathing can be made easily in the mask.
