Title: Fuel injection control device of internal combustion engine
Inventor: HASEGAWA JUN
IPC: F02D41/34
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To set fuel injection timing on the delay angle side rather than normal fuel injection timing to be set after complete explosion in cases where it is judged by a complete explosion judgement means that it is before complete explosion. SOLUTION: An injector 1 to inject and supply fuel to an air intake port 3 is arranged on an air intake pipe 11 of an engine 10. An ECU 30 discriminates whether the engine 10 is in a starting state before complete explosion or not and sets injection starting timing at the delay angle side rather than normal injection starting timing (for example, 60 deg. CA before air intake TDC) to be set after complete explosion in cases where it is judged that it is before complete explosion. At this time, the ECU 30 compares valve opening time of an air intake valve 1.6 in a following combustion cylinder and fuel injection time in the following combustion cylinder in the same way with each other, and when the valve opening time of the air intake valve 16 is longer as a result of comparison, the injection starting timing by the injector 1 is made previously specified timing (for example, 30 deg.  CA after air intake TDC). Additionally, as a result of comparison, when the fuel injection time is longer, the injection starting timing by the injector 1 is transferred to the spark advance angle side.

Title: Microprocessor system
Inventor: HIGUCHI RYOHEI
IPC: G06F15/78
Filed: 1990-03-27
Abstract: PURPOSE:To hold a state that is set right before the execution of an instruction is interrupted by cutting off the clock signal inputted to a timer and stopping the operation of the timer during a debugging job. CONSTITUTION:When the execution of an instruction is stopped during a break or single step operation, one of both inputs of a 2-input OR gate 13 is set at a high level. Thus an S RFF 14 is set and the output 17 of the FF 14 is set at a high level. Then the output of a 2-input NOR gate 18 is set at a low level. As a result, the output of a 2-input AND gate 19 is set at a low level regardless of the state of a system clock 20. Then a timer 1 stops its time counting action. When a system is reset from a debugging action, a processor 3 sets the reset input 16 of the FF 14 at a high level and resets the FF 14. As a result, the outputs of the FF 14 and the gate 18 are set at low and high levels respectively. Thus the timer 1 can restarts its time counting action.
