摘要： PURPOSE:To generate the rotary angle pulses having a smaller angle under the state the number of rotary angle reference bodies, which are equally spaced around the outer surface of the rotary body and whose passage is detected by a sensor, is made smaller. CONSTITUTION:A latch circuit 8 receiver binary coded counted outputs immediately before the reset from a counter 7, with the outputs being shifted by every (n) bits to the lower position. A down counter 9 presents the latch output, sequentially counts down the clock pulses, and executes the repeating operaions of generating the pulse output when the counted value reaches the preset value. The shifting amount of the bit is set so that an expression X=360 deg./thetaX2n is satisfied and X becomes the minimum value of an integer, where X is the number of the rotary angle reference bodies, theta is the intended unit detecting angle, and (n) is the shifting amount of the bit in the counter output. In this way, the rotary angle pulse having the fine unit rotary angle can be generated by using the smaller number of the rotary angle reference bodies.

摘要： PURPOSE:To eliminate the influence of the firing noise by blocking the input to the firing control section by means of the firing control signal and the output from the mono-multi circuit including the firing noise production area while not reaching to the referential position signal generating area. CONSTITUTION:The OR gate 10 is feeding the signals D, E from the firing control section 7 to the monostable multivibrator circuit 11, thereby it is triggered for every falling of the signals D, E and the output will provide the predetermined time L. The time T where said circuit 11 will be L is set in the range from the start of the firing of the signals D, E to the completion of the noise production except the production interval of the referential position signals B, C. Consequently when the output from the circuit 11 is L for the time interval T, the AND gates 8, 9 are closed to disable the input of the noise from the referential pickup sensors 2, 3 into the firing control section 7. Consequently the stable firing control can be performed reliably without the influence of the firing noise.

摘要： PURPOSE:To enable to move a motorcar in case the trouble or the like of a microcomputer by a method wherein an ignition signal having a proper ignition timing based on the standard position pulse of the rotation of an engine and a crank angle detecting pulse is outputted from the microcomputer automatically. CONSTITUTION:The standard position detecting pulse So is outputted at a time when the protruded part of a magnetic disc on a crank shaft is passing a standard position sensor and it is offeringly inputted into the microcomputor 4. On the other hand, at every time when 180 pieces of protuberances of another magnetic disc on the same shaft is passing a crank angle sensor, the crank angle detecting pulse S1 is outputted, then, the frequency of the pulse S1 is multiplied two times and is turned to the pulse S2 while the pulse S2 is inputted into an input terminal T1 at every time when the crank shaft is rotated once. In the microcomputor 4, a control pulse S5, making an energy accumulating time for an ignition coil 14 constant, is outputted by the detecting pulse So and the multiplied pulse S2 and thereby determining the ignition timing. Further, when the microcomputor or the like is abnormal, the ignition timing is determined based on a pulse S3 determined by a counter 7 counting the frequency multiplied pulse S2 and a decoder 8.

摘要： PURPOSE:To make ignition energy sufficient at the time of high speed driving by a method wherein electrification time to an ignition coil is changed according to a revolution by providing an electronic driving circuit. CONSTITUTION:An ignition spark is generated through a driving circuit 9 and by setting a flip-flop 1 with a base pulse input A, and a condenser 4 is charged up to supply voltage Vcc. An angle pulse B is obtained through an angle pulse input 20 through which voltage of the condenser 4 is discharged by fixed quantity as shown in C. When voltage of the condenser 4 comes to the voltage to be fixed by a function generator 7 according to a revolution, the flip-flop 1 is reset and electrification to an ignition coil 91 is started. Therefore, output Q as shown in a figure D is interruption time of an electric current of the ignition coil and output Q as shown in a figure E is electrification time, which are fluctuated according to the revolution. Then, the output Q varies to a direction a as shown in the figure E and ignition energy does not become insufficient.

摘要： PURPOSE:To enable the ignition timing to be detected accurately in an ignition timing detector for use in an internal-combustion engine by an arrangement wherein a signal indicative of the time between an ignition signal and a crank angle signal is detected and computed for correction. CONSTITUTION:A signal (A) is generated at a reference crank position. Flip- flops 1, 4 are reset in accordance with the signal (A). The flip-flop 1 is triggered by an ignition signal C. Therefore, pulses D, G indicate a phase difference between the reference signal (A) and the ignition signal C. A signal E which is a logical sum of this signal and the crank angle signal is obtained by an AND gate 2. A pulse I indicative of a phase difference between the ignition signal C and a nearest crank angle signal is obtained by the flip-flop 4 and an exclusive OR gate 5. An arithmetic circuit 6 corrects the signal E with the signal I. This arrangement detects the ignition timing with a high accuracy.
