Fluid pressure is supplied from a pressure source in a separate path to each of these openings. The opening, which has the slot disposed thereover, has a different pressure in its path from the pressure source than the other openings so that the location of the slot, if it is in the surface of the substrate disposed next to the openings, can be ascertained.
