The present invention provides a photoresist composition comprisinga resin which comprises a structural unit represented by the formula :wherein Q1 and Q2 independently represent a fluorine atom etc. A first network is coupled to a sensor array and communicates data. In another configuration, two or more reed switches, each acting independent of one another are simultaneously activated by a single magnetic field. The rotor assembly includes locking bars having pins directed radially towards the combination post. As the substrate advances past the deposition aperture a layer is formed, potentially from bolt end to bolt end.
