摘要： PURPOSE:To certainly prevent erroneous indication or the movement of an indicator by forcibly indicating zero with the lowering of the voltage of the power supply of a signal processing circuit to predetermined voltage or less. CONSTITUTION:Signals changing by the characteristics of a SIN.COD wave or the like are outputted to cross coils 1a, 1b crossing each other at a definite angle from a pair of the cross coil driving AMPs 2a, 2b of the final stage of a signal processing circuit 3 corresponding to quantity to be measured. An indicator 5 is operated in connection with a movable magnet 4 whose angular displacement is determined by the synthetic magnetic field generated in the coils 1a, 1b. When the voltage of the power supply of the circuit 3 lowers to a predetermined value at this time, a detection circuit part 7 is operated and an control signal is outputted to the AMPs 2a, 2b from a control circuit part 8. By this constitution, the output signal setting the magnet 4 to a position where the indicator 5 indicates zero is forcibly outputted to the coils 1a, 1b from the AMPs 2a, 2b and the erroneous indication or indication movement of the indicator 5 is certainly prevented.

摘要： PURPOSE:To handle a low frequency input and a high frequency input by varying a subtraction period and varying an addition value in inverse proportion to the period. CONSTITUTION:Every time a pulse signal (a) generated by the specific quantity variation of an object of measurement is inputted, a constant value is added to an operand value and a specific value is subtracted at a specific period; and the indication of a display part 3 is determined according to the result and the display part is driven. At this time, the switch 16 of a conversion part 1 compares the arithmetic processing result or the period of the pulse signal with a preset value and sends a switching signal to a timing pulse generation part 12 according to the result. Then the generation part 12 make the arithmetic processing signal period long by increasing the frequency division ratio of reference pulses at the time of the low frequency input to perform the subtraction processing smoothly and also sends the reciprocal signal of the frequency division ratio to a constant generation part 11 to output a division addition signal which is decreased by the extension of the arithmetic processing signal period. For the high frequency input, the arithmetic processing signal period is made short by decreasing the frequency division ratio to perform the subtraction processing speedily and the division addition value is increased in inverse proportion to the arithmetic processing signal period.

摘要： PURPOSE:To handle a low frequency input and a high frequency input by deciding whether an arithmetic processing result if larger or smaller a set value and whether the input period of a pulse signal is longer or shorter than a set period by a decision part, and varying an arithmetic processing period according to the comparison results. CONSTITUTION:Every time the pulse signal (a) generated by the specific quantity variation of an object of measurement is inputted, a constant value is added to an operand value and a specific value is subtracted at a constant period; and the indication of a display part is determined according to the result and the display part is driven. At this time, the decision part 16 of a conversion part 1 decides whether the arithmetic processing result is larger or smaller than the set value and whether the input period of the pulse signal (a) is longer or shorter than the set period. Then a timing pulse generator 12 switches the arithmetic processing period between a long and a short period corresponding to the low frequency input and high frequency input according to the decision results.

摘要： PURPOSE:To easily set a frequency dividing ratio which is displayed with a fraction by constituting a main part of two arbitrary coefficient output devices and two adders. CONSTITUTION:The title divider is composed of two arbitrary coefficient output devices and two adders. The arbitrary coefficient output device is composed of two presetting counters 1 and 2, synchronized with an input pulse signal and inputs the set numerals to respective adders I and II. An adder I always receives the input of a counter 1, successively adds an input numerals and at the prescribed time, the numeral is re-written to the numeral of an adder II. The adder II always adds the added result of the adder I and the numeral of a counter 2 and clears the everytime added result. When the overflow occurs at either of the adders I or II, a carry bit signal is taken out through an OR circuit 3. Simultaneously, the added numeral of the adder I is re-written by the added result of the adder II. From the counted value of the counters 1 and 2, the arbitrary frequency dividing wave can be obtained.

摘要： PURPOSE:To set a constant K in the relationship theta=K.R for determining the indicating theta of an indicating instrument in relation to the number of revolutions R of engine to a value which is not changed by increasing or decreasing the number of cylinders, namely by the pulse rate. CONSTITUTION:The relationship theta=K.P can be converted into the following equation: theta=K.(1/(P.T)) (where P: pulse rate, T: TA pulse period), where P.T can be regarded as the time required for one revolution of an engine. Count value (n) determined by the number of cylinders is added from a count value output circuit 2 to a period counter 3 for every sampling signal of fixed period T (SK) outputted from a sampling clock circuit 1 to calculate a counting value N. The addition is performed in nearly in one cycle period of the engine, and in the following period, a counting value N of the period counter 3 is reset so as for the operation to be performed again. The counting value N becomes equal to P.T. Besides, the value N can be represented by the following equation: N=(T/T(SK)).n, and the value remains the same regardless of the number of cylinders. That is, because the relationship for P.T is similarly established, a constant K can be definitely set as K=theta.N.
