In one illustrative example, a method of making a read sensor of a magnetic head involves forming a barrier structure which surrounds a central mask formed over a plurality of read sensor layers; etching the read sensor layers to form the read sensor below the mask; and depositing, with use of the mask and the barrier structure, hard bias and lead layers to form around the read sensor. The method includes the steps of operating the engine without injecting water into the gas flow of the engine, injecting water at a first flow rate into the gas flow for power augmentation once engine full power is about reached, and injecting water into the engine at an increased second flow rate for evaporative cooling of engine components downstream from the high pressure compressor. The drinks dispenser is therefore modular in construction, with the frame providing the structural strength of the dispenser and the cover fulfilling the aesthetic requirements. Based on a result of the determination, the attribute of pixels in the extracted image area is changed by a change unit. The tones in each group of tones are uniformly spaced with one symbol being transmitted on each tone. The rocker panel or side sill may be made by gas-assisted injection molding wherein a mold including a mold cavity having the desired final shape, including one or more channel cavities, is provided.
