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 the over-rotation and enhance maneuverability by a method wherein an ignition circuit is made to be inoperative by a misfire circuit at the time of over-rotation, said misfire circuit being made to be inoperative by an operation signal of a brake lever. CONSTITUTION:At the time of over-rotation, a backward voltage generated by a pluser coil 2-2 exceeds the voltage of a Zener diode 14, so that a transistor 15 is turned ON and a capacitor 16 is charged. The charge on the capacitor 16 turns a transistor 17 on so that a thyristor 18 is made to conduct, causing the ignition circuit to be inoperative. At the time of engine starting, a transistor 21 in a flip- flop (FF) 19 is ON, and when a brake lever switch 7-1 is turned ON, a transistor 20 in the FF 19 is turned ON and a transistor 25 is turned ON, whereby the thyristor 18 is made to be inoperative so that the misfire circuit cannot operate. Accordingly, the over-rotation can be prevented, and the running can be enabled by merely operating the brake lever.

摘要： PURPOSE:To prevent idle ignition by disabling function of ignition drive means from the time point when intermediate pulse in three pulses to be produced upon rotation of crank shaft by predetermined angle against the referential position is produced until the time point when first pulse will disappear CONSTITUTION:Upon rotation of crank shaft 1, approximately sinusoidal pulsating signals A, B are produced sequetially from electromagnetic pickups 4, 5 while upon rotation of cam shaft 25, approximately sinusoidal pulsating signal C is produced from an electromagnetic pickup 28. Said signal C is produced during the interval after extinction of said signal A corresponding with the compression dead center until production of said signal B corresponding with the exhaust top dead center. Said signal C is fed to a diode 29, a resistor 30 and a capacitor 31 to produce positive recharging pulse D which will cause turning on of transistor Tr32 to recharge a capacitor 33 and upon exceeding of the recharged voltage over predetermined level, Tr42 is turned on thus to disable turning on of Tr11, Tr17.

摘要： PURPOSE: To simplify the construction of a crank angle detector by detecting the shape at a specified angle pitch provided on a rotor and one shape different therefrom to perform a logical processing of resultant outputs.
CONSTITUTION: Projections 10aW10h at an equal angle pitch of a magnetic rotor 10 rotating integral with the rotation of a crank and one projection 10i different in the phase relationship therefrom are detected with an electromagnetic pickups 3 and 4 to trigger monostable multivibrators 11 and 12. AND gates 13 and 14 to which outputs of the monostable multivibrators 11 and 12 are applied are respectively controlled by the output of the monostable multivibrator 11 and the output of the monostable multivibrator 12 via an inverter 15 and produce an output corresponding to the upper dead point and an output corresponding to each crank angle respectively. The arrangement of using only one rotor in stead of two for detecting the upper dead point and the crank angle simplifies the construction of the detector for the crank angle including the dead point.
