The TAN HAND is a product designed to make the application of suntan oillotion easy and cleaner. In the first aspect, the wavelength variation data is provided to control systems that control focus by moving apparatus components including, for example, the mask table, the substrate table or optical elements of the projection optical system. The manufacturing method of the color filter substrate comprises: coating a common electrode layer on a base substrate for forming the color filter substrate; and forming common electrodes of different thicknesses for the color filter substrate units of different sizes by a patterning process. The disconnect switch can connect the utility to the location upon a command from the server and confirmation from a customer. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required.
