The invention relates to a micro fluid chip that leads liquids supplied from a plurality of liquid supply ports, respectively, to a minute flow passage, performs mixing and reaction of the liquids in the minute flow passage, and obtains a liquid having been processed from a liquid discharge port. The present invention relates to a nozzle and nozzle device for atomisation, in particular a micro-machined reinforced nozzle plate, that may produce small liquid droplets in air or into a liquid with a narrow droplet size distribution and to make small air bubbles into a liquid and to methods of making the same. 0m, wherein the mixing ratios of the coloring pigment, the amorphous organic high polymer and the fine particles are confined to 20-60 parts by weight, 40-70 parts by weight and 1-30 parts by weight, respectively. Also, in each routing message sent from source nodes to target nodes via various paths, a plurality of bits, preferably two bits, are used for the number of mesh nodes operating in the path in the energy-saving mode or are battery-operated when the remaining bits of the routing-message are used for the path metric.
