    ESI format?

    Hello, Is anyone familiar with ESI format of 2D drawing? Additionally, is there any suitable converter from DXF to ESI format? This type of drawing file is pretty old and I have met it at a Norwegian oxy-acetyline CNC cutting machine.

    Voltage Regulator

    I have seen that on PCBs of Fanuc CNC Power Supply, Spindle/Servo Amplifiers they only use AN78xxF regulators. It also seems that this type of regulator is, also, extremely stable at operation, producing very little noise/ripple.
