An offset adjustment amplifier receives a differential error signal representative of the difference between offset voltages of the first and second operational amplifiers and generates offset adjustment signals that are applied to input stages of the first and second operational amplifiers to adjust their respective offset voltages so as to equalize them. Advantageously, the central common area includes a pool in a courtyard. The coupling section has first to fourth circumferential elongated slots in communication with the proximal ends of the first to fourth slits. is applied to the dried web such that the latex comprises less than about 3% by weight of the dry weight of the web.
