Abstract

PURPOSE: To secure a strong impression to the sensibility of the measurer by giving the different color to the display segment from the color given before the readings reaches the fixed level in case the readings becomes higher or lower than the fixed level.
CONSTITUTION: When the fuel tank is filled about 60%, the signals sent from the sensor part are supplied to the A/D converter or counter 4. And the output is turned to the signal which is decoded through decoder 5 to emerge at output terminal 56 in the form of logic "1" along with the voltage applied to segments 1W6 showing 60% via the higher priority circuit. Thus all segments have the green light emission. In this case, transmission gate 7 conducts and transmission gate 8 becomes noncorductive to actuate diode chip G1. Then when the remaining amount of the fuel tank becomes about 10%, the digital signals corresponding to the analog amount turns only output terminal 51 to logic "1". As a result, gates 7 and 8 feature the opposite states to the above, and diode chip R1 gives the red light emission only to the lowest-rank segment. Thus a small residual amount of the fuel can be impressed strong.
