Abstract: A fluid controlling method includes, sending an inner fluid, and sending an outer fluid coaxially with the inner fluid, wherein one of the inner fluid and the outer fluid includes a corkscrew flow that flows spirally, and wherein the inner fluid and the outer fluid are in contact with each other.

Abstract: A reaction method using a microreactor, comprises: forming, in a microchannel, an at least two-layered laminar flow in n kinds (n is an integer of 3 or more) of a fluid 1, a fluid 2, . . . , and a fluid n at least two kinds of which are mutually incompatible; and pulsating at least one kind of the fluids.

Abstract: A microreactor device comprises: a microchannel that sends one or more fluids; and a section that isolates vibrations to a first portion of the microchannel.

Abstract: A micro fluidic device comprises a micro channel in which a plurality of fluids form laminar flows and are supplied, wherein an inner wall of the micro channel comprise a protruding part that is substantially parallel to the flows of the fluids and protrudes in directions substantially vertical to interfaces formed by the plurality of fluids.

Abstract: A microchannel device includes; a microchannel that forms two or more different fluids as a multiphase flow, and a section shape of the multiphase flow having in at least one portion a first shape in which plural polygons are two-dimensionally arranged, and adjacent to one another, a second shape in which a polygon is inscribed in one of a circle and an ellipse, or circumscribes one of a circle and an ellipse, or a third shape in which at least plural circles and polygons are two-dimensionally arranged, and adjacent to one another.

Abstract: A laminated structure includes: a plurality of first electroconductive films each having a prescribed hardness; and a plurality of second electroconductive films each having a hardness that is lower than the prescribed hardness. The first and second electroconductive films are laminated alternately.

Abstract: A fluid controlling method includes, sending an inner fluid, and sending an outer fluid coaxially with the inner fluid, wherein one of the inner fluid and the outer fluid includes a corkscrew flow that flows spirally, and wherein the inner fluid and the outer fluid are in contact with each other.

Abstract: A microfluidic device includes a processing layer and a temperature control layer. The processing layer applies a predetermined process to a subject fluid. The temperature control layer is disposed adjacent to the processing layer to give a predetermined temperature environment to the processing layer.

Abstract: A microstructure includes first and second plates. The first plate defines a recess. The second plate is bonded to the first plate to block an opening of the recess to thereby form a closed vacuum space or a closed space filled with inert gas.

Abstract: In a coin configuration detection method and a coin identification sensor that magnetically detect the coin configuration, coin configuration detection is enabled to be accurately performed. Moreover, in a coin identification apparatus, the coin identification accuracy is improved. In a coin configuration detection method (coin identification sensor 1) that magnetically detects the configuration of a coin 2 to identify the kind and/or the authenticity of the coin 2, a magnetic flux change in the vicinity of the surface of the coin 2 is detected by a detection coil 7 in which a coil central line is along the surface of the coin 2 and a coil peripheral surface is locally opposed to the surface of the coin 2 while an AC magnetic field along the surface of the coin 2 is generated in the interior of the coin 2 and/or in the surface space of the coin 2. Moreover, the coin identification apparatus identifies the coin 2 based on the detection signal of the coin identification sensor 1.
