A fine channel device including a fine channel provided with at least two inlet ports for feeding fluid, inlet channels communicated with the inlet ports, a confluent portion communicated with the inlet channels, a branch portion communicated with the fine channel, from which at least two outlet channels are branched to feed predetermined amounts of fluid, and outlet ports communicated with the outlet channels. The fine channel is provided with a plurality of partition walls arranged along a boundary formed by at least two kinds of fluid fed from the inlet ports so as not to cause mutual contamination of fluid. Furthermore, the plurality of partition walls are spaced apart at intervals in a flowing direction of fluid.

Fine channel device and a chemically operating method for fluid using the device

A fine channel device for performing a chemical treatment or for producing fine particles, capable of supplying a liquid to the fine channels evenly and producing products in a large quantity is provided. The fine channel device includes a storage space having a circular or polygonal recess for temporarily storing fluid, and supply channels formed in a radial direction from the storage space. A small chemical plant includes a plurality of the fine channel devices as fundamental constituents and a mechanism to supply at least one fluid and a mechanism to recover products produced.

Fine channel device, desksize chemical plant and fine particle producing apparatus employing them

An information measuring apparatus having a fine channel device comprises at least one detector for measuring information supplied from a plurality of measuring portions formed in the fine channel device, a position-holding/determining means for holding and positioning the fine channel device, a rotating means for rotating the fine channel device at a predetermined angle, a position-determining means for positioning the measuring portion and the detector, wherein information supplied from the measuring portions in the fine channel device is measured successively by rotating the fine channel device at the predetermined angle, whereby information from the measuring portions is stably and efficiently measured.
