Title: Electronic control fuel injection method
Inventor: IYODA HISAO
IPC: F02D41/12
Filed: 1983-06-24
Abstract: PURPOSE:To eliminate an abrupt drop of an engine speed and prevent an engine stall from occurring by increasing the fuel injection quantity when the fuel injection is resumed during deceleration. CONSTITUTION:An electronic control circuit 40 sets a fuel augmentation permission flag F1 for resumption only when the fuel injection is being stopped during deceleration, and it subtracts the currently calculated engine speed Ne from the previously calculated engine speed NeOLD based on the output of a crank angle sensor to determine a decrease  Ne of the engine speed. A flag F2 is set only when  Ne is a predetermined value Le or more, and the engine speed NeOLD value is replaced with the Ne value. Next, the asynchronous injection injecting the fuel not in synchronization with a crank angle is performed only when the injection is not stopped with a throttle switch 29 set on and the flags F1, F2 are set, then the flags are reset. The asyncyronous injection is performed once to increase the fuel injection quantity when the fuel injection is resumed after its stop by controlling the injection in this manner, thus an engine stop can be prevented.

Abstract: PURPOSE:To increase reverse voltage resistance while obtaining a high-speed switching response characteristic by shortening the lifetime of a small number of carriers, irradiating the electron beams of low energy to the surface of a semiconductor and annealing only a section in the vicinity of the surface. CONSTITUTION:Radiation such as X-rays or electron rays having the high  energy of not less than 0.5MeV acceleration voltage for example, the electron rays of 1.5MeV acceleration voltage is irradiated to a P<+>-N junction diode in planar structure in which a P<+> layer is formed by selectively diffusing the boron of high concentration to an N type silicon substrate. Accordingly, the semiconductor device, which has the high-speed switching characteristic and the reverse voltage resistance thereof is hardly degraded, is manufactured by annealing only the section in the vicinity of the surface of 100mum or thinner while the lifetime of a small number of carriers in the N type substrate is left as it is shortened. The electron beams of low energy are irradiated as a means for annealing only the section in the vicinity of the surface.
