A gemstone fluorescence measuring device according to the invention generally includes an ultraviolet emission chamber, a UV radiation source, and a light meter assembly. The feed water is cathodically electrolyzed in the cathode chamber to produce alkaline electrolyzed water and is anodically electrolyzed in the anode chamber to produce electrolyzed water whose pH is modified. Preferably, the data consists of audio data of the song, lyrics data of the song and image data relating to the song and the copyright information is allotted respectively to the audio data, lyrics data and image data. Parity data is calculated for reconstructing an object upon occurrence of a storage device failure. By forming the resistive element through the wafer, a resistive element, such as a large resistive element, can be formed on the wafer that requires very little silicon surface area.
