A gold wire having a non-pure gold core member and a layer of pure gold coating covering the non-pure gold core member. A main bus transmits and receives data to and from the cache memory and the processor. The light source unit can include a light source, and a converting part for converting light from the light source to a narrow width light. Selectivity of product formation can be achieved by varying one or more of the temperature, pressure, catalyst, flow rates and also by varying the ratios of aromatic substrate to acylating or alkylating agent. The linkage is adapted for sequential reciprocation of at least a portion of each of the objects through its respective port so that the mice emerge from and return into the cheese in a circular sequence that entices the cat. The movable body spectrum measuring apparatus further includes a data transfer device which acquires reconfigured spectrum data by reconfiguring the measured spectrum data so that selected information as predetermined information is selected from the information contained in the measured spectrum data.
