An electrolytic polishing apparatus for electrolytic-polishing a conductive film subject to formed on a substrate including a resistance measuring unit for measuring the resistance of the film. To estimate the estimated value, an oscillator counter counts pulses of a reference clock supplied from an independent oscillator while a reading counter counts pulses of the receiving clock. A method of manufacturing a fluid dispensing subassembly includes forming a body pressure chamber from a body plate or a set of plates including a body plate, and adhesively bonding a diaphragm plate to at least the body plate of the fluid dispensing subassembly. The server device generates an updated secure keying data set with a second version identifier and sends, to the member devices, a key push message that includes the updated data set. The analogue circuit arrangement realizing the method comprises a by-pass input for receiving the three-state signal, whereby the signal represents justification events upwards andor downwards, filtering means for filtering the pulse signal, and adding means for adding the filtered pulse signal to the output signal of the loop filter, whereby the added output signal controls the loop oscillator.
