Abstract

PURPOSE:To reduce greatly and dispersion of the set time, by decreasing the resistance value of the fixed resistor parallel to the variable resistor and the allowance value of the above resistance value against the full resistance value of the variable resistor and its allowance value. CONSTITUTION:Charging circuit A charges capacitor 5 after power switch 2 is turned on, and this charging voltage ec varies according to the time. And now if the connection is given between terminals S1 and S0 of selection switch 12, set voltage ed supplied to comparator 13 becomes equal to sliding terminal voltage ed1 of variable resistor 9. And ed<ec is obtained after a fixed time and according to the level of voltage ed1, and thus output voltage V0 of comparator 13 becomes the L level. And relay 17 is turned off after timer time T according to voltage ed1. Here if the full resistance value of the variable resistor is set to Rv, the allowance value of dispersion is set to + or -Kv, resistance value of fixed resistor 7 parallel to the variable resistor is set to RF, and its dispersion allowance value is set to KF respectively, the dispersion of time T can be reduced extremely by securing RF<= (Rv/n)(RF/Kv).
