    摘要： A frequency demodulator includes an analog-to-digital converter for converting an inputted FM signal into a digital signal. A 90.degree. phase shifter is used to phase shift the converted digital signal. The phase shifted signal and the converted signal are utilized to determine the results of tan.sup.-1 (X/Y). X represents the converted signal, and Y represents the phase shifted signal. The result from the calculation is delayed for a period of time equal to one sampling cycle. The frequency demodulator also includes a subtractor for subtracting the delayed signal from the calculation result. A discontinuity corrector corrects any discontinuity in an output from the subtractor, and a reversal phenomenon compensator compensates the output from the discontinuity corrector when the output from the discontinuity corrector exceeds a predetermined range of levels. These levels correspond to an appearance of discrete lines of black or white color on a reproduced picture.

    摘要： Disclosed is a fuel control apparatus in an internal combustion engine. When the running mode the engine is changed into acceleration again from deceleration after acceleration, the fuel becomes too rich if the conventional continuous correcting factor is used. In order to properly reduce the quantity of fuel supply in that case, the number of engine revolutions is counted from a point of initiation of deceleration to a point of initiation of acceleration again to thereby calculate a proper value of the continuous correcting factor corresponding to the count, so that fuel is supplied to the internal combustion engine with a quantity corrected by the thus calculated value of the continuous correcting factor.

    摘要： A fuel is injected based on the rpm of the engine and the suction air rate. The fuel injection amount is corrected depending on a map of fuel injection share correction coefficient prepared in advance and determined by data such as a throttle valve opening and the rpm of the engine so that amounts of fuel injected will be even at the respective cylinders. The fuel injection share correction coefficient is for correcting fuel deviation due to construction of suction passage to with the respective cylinders or for correcting fuel deviation due to arrangement of two injectors in one bore with respect to the throttle valve shaft.

    摘要： In a method for performing magnetic recording and reproducing an apparatus is used which includes a magnetic head carried by a piezo-electric movable element, the position of the magnetic head is detected such that reproduction signals are maximized within the range of transverse movement of the magnetic head, i.e., the range of less than 1/3 of the track width is detected. Their corresponding pattern signals are inputted as renewed successively. The result of this method is that a good reproduction image can be obtained even from a magnetic tape having locally different record levels, following any track curvature change with time, without deteriorating the quality of image during reproduction.
