Car speed detection device Circuit drawing

The rating electric power of the resistors that are not designated is 1/8W.
The resistance voltage of the electrolytic capacitors that are not designated is a 10V. Even it over is OK. The form becomes big.

As for resistor R15, R26 and also R27, refer to the page of the "Adjustment of Car speed detection device", because adjustment may be necessary.

There are the following things in the compatible kind of the voltage comparative device (uPC319).
Because these things are same entirely even the pin arrangement the pattern drawing is possible use as it is.

    LM319 : National Semiconductor Corp.
    LM319 : Singnetics Corp.
    NJM319 : JRC ( Japanese company )
    AN1319 : Natioanl ( Japanese company )
