The fluid mixing element in accordance with this invention forms a first internal flow channel whose starting end opens on an end surface of one end part and whose terminal end opens on an end surface of the other end part and a second internal flow channel whose starting end opens on a side peripheral surface of a middle part and whose terminal end opens on an end surface of the other end part. It is possible for the fluid mixing element to securely mix a first fluid flowing in a main flow channel with a second fluid flowing in a sub-flow channel by the use of a pipe with a short length with a simple arrangement.

A pressure difference generating apparatus includes a first pipe, a second pipe and a third pipe. The first pipe have a first inlet. The second pipe disposed inside of the first pipe has a conical inlet runner, a conical outlet runner and a neck portion between the conical inlet runner and outlet runner. The third pipe has a third conical outlet portion extending into the conical inlet runner. A first fluid and a second fluid flow into the first pipe and the third pipe separately in different flow rates. A negative pressure generated between the third conical outlet portion and the conical inlet runner allows at least part of the first fluid to flow into the conical inlet runner, then the neck portion, then the conical outlet runner, and finally out of the second pipe with the second fluid.

A combined-blade open flow path device is a fluid flow path device where flow paths are adjacent to each other. The combined-blade open flow path device comprises a substrate configured to constitute a bottom portion of the flow paths; and blades erected on a surface of the substrate, the blades being configured to constitute side walls of the flow paths, wherein the blades are erected in groups, each of the groups extending from an upstream side to a downstream side in a flow direction of a fluid with a space between each of the blades in the flow direction of the fluid in each of the groups for making conduction of the fluid between the adjacent flow paths possible, and wherein one end of one of the flow paths is configured to be in contact with the fluid and is configured to make a flow of the fluid possible.

In certain embodiments this invention provides a pulsed-laser triggered microfluidic switching mechanism that can achieve a switching time of 70 s. This switching speed is two orders of magnitude shorter than that of the fastest switching mechanism utilized in previous FACS.

Embodiments of the device relate to a modular injector (100) for injecting a gas into a processing chamber (42), comprising at least two adjacent injectors (1), each injector comprising an inlet for receiving a gas wave or a gas flow, a flow shaping section (2) having left and right sidewalls that diverge according to a divergence angle relative to a propagation axis of the gas, for expanding the gas in a direction perpendicular to the propagation axis, and an outlet for expelling the gas. The modular injector forms an equivalent large injector having an equivalent large outlet which includes the outlets of the adjacent injectors and expands the gas over the equivalent large outlet.

A method of fabricating an elastomeric structure, comprising: forming a first elastomeric layer on top of a first micromachined mold, the first micromachined mold having a first raised protrusion which forms a first recess extending along a bottom surface of the first elastomeric layer; forming a second elastomeric layer on top of a second micromachined mold, the second micromachined mold having a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer; bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.

A fan assembly for creating an air current is described, the fan assembly having a nozzle, a system for creating an air flow through the nozzle and a filter for removing particulates from the air flow, the nozzle having an interior passage, a mouth for receiving the air flow from the interior passage, and a Coanda surface located adjacent the mouth and over which the mouth is arranged to direct the air flow, wherein the fan provides an arrangement producing an air current and a flow of cooling air created without requiring a bladed fan, i.e. air flow is created by a bladeless fan.

An electrochemical cell system includes a fluid manifold having a layered structure. The fluid manifold includes at least one conduit layer having a first side and a second side. The at least one conduit later has at least one conduit channel.
