Abstract: The present invention provides a method for classifying fine particles, the method comprising: introducing a fine particle dispersion in which fine particles are dispersed in a liquid medium into an inlet of a microchannel having the inlet and a recovery portion; and delivering the fine particle dispersion, which has been introduced through the inlet, to the recovery portion in laminar flow, wherein delivering the fine particle dispersion includes classifying the fine particles using the difference in sedimentation speed or floatation speed among the fine particles in the fine particle dispersion. The present invention also provides a device used in the method for classifying fine particles.

Abstract: A simulation condition input apparatus inputs information required for simulation analysis on a system including plural element members. The apparatus includes a display unit, a specifying unit and an input unit. The display unit displays the plural element members on a screen with geometrical shapes corresponding to the element members. The specifying unit specifies a contact portion between at least one set of the element members, which is an information input target, on the screen of the display unit. The input unit displays a new window screen and inputs information about a contact state of the contact portion specified by the specifying unit.

Abstract: An icon generating device includes a mode selecting section and an icon generating section. The mode selecting section allows a user to select one display mode for each data file from among a plurality of display modes. The icon generating section generates icon data of each data file, for displaying an icon of each data file in the display mode selected for each data file. The icon generating section outputs the generated icon data of each data file.

Abstract: Disclosed is a method of delivering a fine particle dispersion in the state of laminar flow from an inlet port to an outlet port of a microflow channel having the inlet port and the outlet port, the fine particle dispersion containing fine particles having a volume average particle size of from about 1.5 ?m to about 1000 ?m dispersed in its liquid medium, the specific gravity of the fine particles being from approximately 0.10 to 0.99 times that of the liquid medium, wherein the microflow channel is disposed such that the outlet port is disposed above the inlet port in the buoyant force direction, and the angle of the flow channel from the inlet port to the outlet port is set to from approximately 0 to 45° relative to the buoyant force direction, and wherein the fine particle dispersion is introduced into the inlet port and the introduced fine particle dispersion is delivered to the outlet port. Also disclosed is a device for delivering the fine particle dispersion.

Abstract: The present invention provides a method for treating fine particles contained in a first fluid comprising: feeding the first fluid containing the fine particles and a second fluid to generate two laminar flows; migrating a diffusible substance contained in the first fluid into the second fluid at an interface between the first fluid and the second fluid in the laminar flows; and separating the laminar flows into the first fluid containing the fine particles and the second fluid in a diverging region.
