Abstract: PURPOSE:To automatically compensate a display error due to change in the amount of magnetization by updating and storing the amount of magnetization obtained from the center point of an arc passing through memory decision coordinate points when their number exceeds a specific value. CONSTITUTION:Every time when an automobile drives for a specific time or a specific distance, an amount of change DELTAtheta(m) in a detection advance direction theta(m) is obtained. Then, when the amount of change DELTAtheta is equal to or within an amount of reference change thetas, coordinate points Vx and Vy indicated by detection X-axis and Y-axis direction constituents Vx and Vy at that time are extracted as memory candidate coordinate points.

Abstract: PURPOSE:To disconnect power supply to a D/A converter without inviting any DC output by making the difference between two inverters to zero by fixing the inputs of the two inverters to '1' or '0' upon detecting the disconnection of the power supply. CONSTITUTION:When power supply is disconnected at time tau, the output of a power supply disconnection detector 2 becomes '1' and the clock signals of D-flip flops 4 and 5 respectively fall at time tau1 and tau2, and then, an output terminal Q outputs '0'. As a result, AND gates 6 and 7 always output '0' after the time tau1 and tau2. The signals of the gates 6 and 7 are respectively supplied to the (+) and (-) terminals of a differential amplifier 14 through D-flip flops 8 and inverters 10 and 11 and 12 and 13. Namely, the input voltages at the (+) and (-) terminals are '0' and the output of the amplifier 14 also become '0'.
