    Abstract: In the case of passing a reagent in a reaction channel in a microchip, which carries a reactant capable of reacting with the reagent on the wall thereof, and bringing the reactant into contact with the reagent so as to carry out a reaction, the reagent is efficiently passed to the reactant to thereby promote the progress of the reaction. In carrying out the reaction as described above, the reagent (30a) is passed in such a manner that the periphery of the gas/liquid interface at the front end of the reagent moves forward and backward along the wall face of the reaction channel (10). After the completion of the reaction between the reagent (30a) and the reactant, another reagent (30b), which is to be reacted with the reactant capable of reacting with the reagent that is carried on the reaction channel, is passed into the reaction channel (10) while providing a gas in the front edge side thereof. In carrying out the reaction, the reagent (30b) is passed in such manner that the periphery of the gas/liquid interface at the front end of the reagent moves forward and backward along the wall face of the reaction channel (10).

    Abstract: A fuel cell device has a small and compact structure as a whole. The fuel cell device employs a fuel cell (e.g., direct methanol fuel cell of an MEA structure) using liquid fuel. Diluted liquid fuel is prepared by diluting the liquid fuel (methanol-contained liquid in the case of DMFC) with dilution liquid, and is supplied to the fuel cell. A first pump unit stacked on the fuel cell supplies the diluted liquid fuel to the fuel cell while diluting the liquid fuel by mixing the liquid fuel and the dilution liquid together. A second pump unit stacked on the fuel cell collects liquid (water usable as dilution liquid in DMFC) produced by an electrochemical reaction in the fuel cell.

    Abstract: An ink-jet recording device (1) comprises a first wall member or partition (24a) adjacent to an ink material (38a) and a second wall member or partition (24b) adjacent to an ink material (38b). An elasticity of the first wall member (24a) is different from that of the second wall member (24b). Arranged adjacent to the first and second wall members (24a, 24b) are first and second piezoelectric members (34), respectively. Once the piezoelectric members (34) are biased, they deform to force the adjacent ink materials through the wall members (24a,24b), ejecting ink droplets of different sizes. This ensures the ink-jet recording head to print a halftone image with a high gradation.
