摘要： PURPOSE:To facilitate the manufacture, maintenance and storage by dividing an engine ignition timing control device into an input-output part and a control part comprising the single body of a unit control unit or the aggregate of unit control units each having a minimum capability for controlling one ignition coil. CONSTITUTION:In a series 6 cylindered engine of a motorcycle in which ignition is made in 3 groups set up by dividing 3 standard position sensors and 6 ignition coils in respective group, standard position pulses supplied to the input ports A1-A3 of an input-output unit 1 are supplied to the CPUs 11 of respective unit control units 10a-10c as a parallel signal. Further, a crank angle pulse and a negative pressure signal from an A-D converter 4 are also supplied to the CPU11 of the each unit control unit. The CPU11 sends an optimum ignition signal after counting crank angle pulses, the signal is supplied to each of drivers 5a-5c via a selector 12, and drives each of ignition coils 6a-6c connected to the output terminal of said driver, allowing ignition plugs 7a-7c to be ignited.

摘要： PURPOSE:To maintain operation of an engine by interpolating the standard position pulse for which output is missed, with other standard position pulse free from fault and the crank angle pulse, when the output of the standard position sensor which is used for engine ignition control is missed. CONSTITUTION:When a standard position sensor 1a is down, generation of differential pulse C1 is suspended, and reset for a counter 11 by the pulse C1 is suspended, and the count value rises to 61. When a decoder 13 detects the count value and generates a signal D, the coincidence with the set outputs of flip-flop circuits 15a-15c is required at AND-gates 14a-14c, but the circuits 15a-15c are triggered by the differential outputs C1-C3 in normal time and operated in succession, so in this case, coincidence only in the AND-gate 14a is required, and an output signal E1 is generated. As the signal E1 is nearly synchronized with the differential pulse C1 in suspension, the standard position pulse F1 is interpolated by transmitting the signal E1 through an OR-gate 16a.

摘要： PURPOSE:To make assembling and storage advantageous by dividing an ignition timing control device into an input-output part and a control part as units, by forming the control part such that it can correspond to various engines and by making it possible to ignite and control all the engines with only the change of the input-output part. CONSTITUTION:When classifying the engines of carts into standard position sensor numbers and output driver numbers in every kind of machines, the sensor number of 1 and the driver number of 2 are provided in the series 2 cylinders of a crank, the sensor number of 2 and the driver number of 2 in the series 2 cylinders, series 4 cylinders of a crank, and the sensor number of 3 and the driver number of 3 in the series 6 cylinders. Accordingly, in the first case it is good to combine the input-output unit 1a and control unit 2 of only a driver 6a, in the second case to combine the input-output unit 1b and control unit 2 of drivers 6a, 6b, and in the third case to combine the input-output unit 1c and control unit 2 having drivers 6a, 6c, so that it is possible to make the control unit 2 having many expensive parts such as CPU9 common.

摘要： PURPOSE:To make it possible to prevent engine operating failure by providing a signal processing circuit for delivering false pulses as an ignition control signal when either one of first and second reference position pulses is disappeared. CONSTITUTION:Transistors TR1, TR2 are turned of and off, respectively, by ignition control signals S14, S15 due to reference position pulses S7, S8 so that ignition plugs #1, #4 and the ignition #3, #2 are ignited, alternately. Estimating that the pulses S7 are not delivered, caused by the breaking of wire in a magnetic sensor SN1, since the ignition control signal S15 sets a flip-flap circuit 16 in this case, the output signal S18 of the flip-flap circuit 16 is at high level but the inverted signal S19 is at low level so that a counter 7 counts crank angle pulses. However, a signal S10 becomes rectangular pulses, since the counter 7 is not reset, so that a differential signal S11 during the rise time of the rectangular signal is delivered from a circuit 9, and a signal S12 is delivered from an AND circuit 10 since both signals S11, S18 are at high level, thereby the ignition control signal S14 is delivered without disappearing.

摘要： PURPOSE:To generate signals varying in the level proportional to the frequency by changing a gain of an amplifier through a light receiving element with the control of the intensity of light generated by means of a frequency voltage converter, a voltage-current converter or the like. CONSTITUTION:A DC voltage inversely proportional to the frequency of clocks So from an oscillator 1 is generated with a frequency-voltage conversion circuit 10 and a level converting circuit 20 while a current corresponding thereto is fed to an LED of a photoisolator 40 through a voltage-current converter 30. A strong light inversely proportional to the frequency of the clocks So from the LED of the isolator 40 is received by a light receiving element Rx which feed back controls an amplifier 7 to control the gain of the amplifier 7 through the varying of the resistance value of the element Rx. Thus, the signal varying in the level in proportion to the frequency of the clocks So can be generated from the amplifier 7 and used as a pseudo signal for simulating the rotation of the car engine ranging from the low to high speed.

摘要： PURPOSE:To prevent occurrence of a knocking, by detecting occurrence of the knocking and shifting ignition timing of an engine from a reference signal to the timing when a piston reaches its top dead center. CONSTITUTION:When an engine causes a knocking, a control signal of analog quantity, in accordance with a level of the knocking, is input to a terminal 30, and an analog-digital converter 32 outputs a digital signal thetac having a prescribed data value. As a result, the first and second down couters 13, 15 and an up counter 43, latch circuit 44 and ROM46 are operated to output a signal from an igniter driver circuit 16. Accordingly, ignition timing can be automatically shifted in accordance with the level of a knocking, that is, a rotary speed of the engine.

摘要： PURPOSE:To simplify the scanning driving circuit of a printer unit to record information by converting character information signals, which are read in horizontal and vertical scanning speeds of a high-speed TV receiver, into the scanning speed of a low- speed printer. CONSTITUTION:When picture data to form signals for displaying luminus points of a TV receiver scanning the screen regularly is converted into the scanning speed of printer PRT which prints and records it, coincidence circuit 12 which detects coincidence between printer display line counter 15, which counts printer display lines, and TV display line counter 11 and memory 3 where write data is inputted are provided. Then coincidence between counters 11 and 15 is detected to output a read/write signal to the output of gate 13, and gate 7 is controlled by this signal to write and store one-horizontal line components of picture data into memory 3 in the scanning speed of the TV receiver. This stored picture data is read in the scanning speed of printer PRT and is applied to printer PRT, and this scanning is repeated to record character information, which is read in a high speed, onto printer PRT.
