Disclosed herein are water purifying system and apparatus for simultaneously making ice and cold water using one evaporator, which can make cold water in various forms only by changing the system and make ice of a predetermined amount by using cold water of less than a predetermined temperature as raw water for ice-making, thereby saving energy. The methods and apparatus employ a tag element associated with each object-to-be-located, and interrogation system for searching one or more spatial regions for such tagged items, as well as mechanisms for identifying objects within the interrogated region. A laminated illuminator film may be provided that uses a laminated optical film structure to direct light from a fiber optic input. The horizontal portions, slant portions and vertical portions define a pair of locking apertures, respectively. The resist composition has a high sensitivity, high resolution and minimized LER.
