摘要:
A microfabricated sheath flow structure for producing a sheath flow includes a primary sheath flow channel for conveying a sheath fluid, a sample inlet for injecting a sample into the sheath fluid in the primary sheath flow channel, a primary focusing region for focusing the sample within the sheath fluid and a secondary focusing region for providing additional focusing of the sample within the sheath fluid. The secondary focusing region may be formed by a flow channel intersecting the primary sheath flow channel to inject additional sheath fluid into the primary sheath flow channel from a selected direction. A sheath flow system may comprise a plurality of sheath flow structures operating in parallel on a microfluidic chip.

Air stream transfer apparatus capable of preventing particles in a transfer passage from adhering to an object to be processed and removing the particles. The apparatus is characterized in that a transfer face and a transfer passage partition both constituting a transfer passage are made of an electroconductive material and each have a thin insulating layer on the surface; a planer dust collecting electrode is opposed to an object to be processed; means is provided for bringing the dust collecting electrode and the face to be cleared of dust close to each other while jetting air; and means is provide for applying voltages between the transfer face and the dust collecting electrode and between the transfer passage partition and the dust collecting electrode. Another apparatus is characterized in that a transfer face and a transfer passage partition both constituting a transfer passage are made of an electroconductive material and each has a thin insulating layer on the surface; means for transferring a pre-charged semiconductive plate-shaped body a float along the transfer passage is provided; and the semiconductive plate-shaped body is used as a dust collecting electrode.

A swirl chamber (16) interposed at covergence of plurality of divergent pneumatic forwarding tubes (11,12) and communicating with the tubes (11,12). Intramural of the chamber (16) transporter capsule (15) caused to perform a complex motion, the motion being predominantly a swirling swerve, by means of mechanical, electromagnetic, magnetic and/or pneumatic forces caused to act on the capsule (15), thereby accomplishing a desired change in direction of longitudinal travel of the capsule (15). The chamber (16) defined by means of enlargement in transverse dimension of the tubes (11,12), dimensions of the chamber (16) being sufficient to accommodate the complex motion.
摘要:
A semiconductor wafer handling apparatus and method for transferring a wafer, one of whose faces has been already polished, from a wafer holder, which holds the wafer with the wafer's polished face facing downward, to a wafer cassette submerged in water contained in a water tank; the apparatus includes a wafer receive assembly and a water tank and the wafer receive assembly has a flat surface and is adapted to swing between an up-facing position at which the flat surface faces upward and a down-facing position at which the flat surface faces downward, and the wafer receive assembly is provided with ejection nozzles which eject water with a force sufficient to keep the wafer floating, and the water tank contains a wafer cassette to receive the wafer, and is capable of forcing the wafer which is left to sink in the water to enter the wafer cassette; whereas the method comprises: dropping the wafer from the wafer holder with the polished face facing downward onto a thin water layer formed over the wafer receive assembly; swinging the wafer receive assembly together with the wafer through an angle of about 180 ° so that the wafer is turned upside down and brought in the water tank, whereupon the wafer sinks through the water with the polished face facing upward; and forcing the wafer to enter the wafer cassette.
