Title: Ignition plug abnormality detecting device for internal combustion engine
Inventor: IKUTA KENJI
IPC: F02P15/00
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To rapidly detect abnormality of an ignition plug due to smoldering during operation. SOLUTION: In this device, from the output voltage of a current detecting circuit to detect a leakage current between the electrode of an ignition plugs, a leakage resistance value Rn is calculated at a step 103 and a decision level correction factor C is set according to an engine operation state at steps 104-110. By multiplying the decision level correction factor C by the leakage resistance value Rn, the leakage resistance value Rn is corrected according to an engine operation state and a leakage resistance value RN after correction is determined at a step 111. When a state (a state that smoldering is detected) that the leakage resistance value RN is lower than a smoldering decision value R1 is continued, for example, 100 cycles, it is decided that abnormality of an ignition plug occurs, and an alarm lamp is lighted ON at steps 112 and 113.  When a state of RN>R2 is continued, for example, 100 cycles during lightening ON of an alarm lamp, it is decided that a smoldering state is restored, the alarm lamp is lighted OFF at steps 114 and 115.

Title: Detecting device for autocorrelation degree
Inventor: ISHIZAKA KUNIMASA
IPC: G06F17/15
Filed: 1987-07-09
Abstract: PURPOSE:To detect the autocorrelation degree in response to a TV signal by forming an integration circuit with an increase/decrease counter and its control circuit for reduction of the circuit constitution and securing the variable threshold value of a comparator as well as the variable delay value, by integrating the information by the integrator based on the absolute value of the difference between two digital signals. CONSTITUTION:An 8-bit TV signal 101 and an input signal 102 having a large autocorrelation degree with the signal 101 are inputted and an absolute value converting circuit 2 converts the difference signal into the absolute value to supply this to a terminal A. This absolute value is compared with the threshold value of a terminal B. The output of a comparator 3 is set at 'H' with B<A. This output is inputted to a 6-clock delay circuit 4 containing 6 pieces of 1-bit data latch circuits 7. Then the circuit 4 is totally reset when an up-down counter 6 is reset. The input signals X and Y to be inputted to the circuit 4 are supplied to a counter control circuit 5. Then the counter 6 performs the addition when signals X and Y are set at H and L and then the subtraction vice versa and otherwise stops its counting action respectively. Thus the autocorrelation degree is detected based on the output 103 of the counter 6.
