Abstract:
Plastic microfluidic structures having a substantially rigid diaphragm that actuates between a relaxed state wherein the diaphragm sits against the surface of a substrate and an actuated state wherein the diaphragm is moved away from the substrate. As will be seen from the following description, the microfluidic structures formed with this diaphragm provide easy to manufacture and robust systems, as well readily made components such as valves and pumps.

Abstract:
The invention relates to the production of a micromechanical component, comprising a substrate (10), made from a substrate material with a first doping type (p), a micromechanical functional structure arranged in the substrate (10) and a cover layer for the at least partial covering of the micromechanical functional structure. The micromechanical functional structure comprises regions (15; 15a; 15b; 15c; 730; 740; 830) made from the substrate material with a second doping type (n), at least partially surrounded by a cavity (50; 50a-f) and the cover layer comprises a porous layer (30) made from the substrate material.
Abstract:
The present invention provides a micropump comprising a silicon substrate (38), which is sandwiched between glass substrates (39, 40) and which is formed with a diaphragm (36) and a valve, the valve including a valve membrane (50) and a valve member (35) for controlling fluid flow through a through-hole (34a) in the valve membrane, the valve member engaging one of the glass substrates. The diaphragm and the valve membrane are disposed closer to the glass substrate engaged by the valve member than to the other glass substrate.
Abstract:
PROBLEM TO BE SOLVED: To provide a turbomolecular pump that can produce a high vacuum against a high exhaust pressure, also can be used in an instrument where an application may be portable, hand held or space limited. SOLUTION: A radial turbomolecular vacuum pump includes a rotor made from a silicon rotor surface comprising monolithically fabricated micro blades, and a stator made from a silicon stator surface comprising corresponding monolithically fabricated grooves. The micro blades and grooves are arranged in multiple rings, and the rotor and stator disks are placed in proximity, creating interdigitated stator and rotor blade rings. The interdigitated stator and rotor blade rings form a multi-stage compression in a radial direction. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a system to fabricate and actuate microstructure created from various layers adhered by an ON/OFF valve, a switch valve, and a pump. SOLUTION: A method of fabricating an elastomeric structure, comprises : a process where a first micromachined mold has a first raised protrusion which forms a first recess extending along a bottom surface of a first elastomeric layer 20; a process where a second micromachined mold has a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer 22; a process where the bottom surface of the second elastomeric layer 22 is bonded onto a top surface of the first elastomeric layer so that a control channel 32 is formed in the second recess between the first and second elastomeric layers; and a process where the first elastomeric layer 20 on the top of a planar substrate such a flow channel is formed in the first recess between the first elastomeric layer and the planar substrate.
