| 20140079605 | FLOW PASSAGE CONTROL MECHANISM FOR MICROCHIP - A channel control mechanism for a microchip has a laminated structure formed of members including elastic members, and includes: a sample reservoir for packing a sample therein; a reaction reservoir in which mixture and reaction of the sample are performed; and a channel formed in a middle layer of the laminated structure, for bringing the sample reservoir and the reaction reservoir into communication with each other. The channel control mechanism performs the reaction and analysis in such a manner that the sample is delivered into the reaction reservoir through the channel. A shutter channel (pressurizing channel) is provided in a layer different from a layer in which the channel is formed so that the pressurizing channel partially overlaps the channel. The channel is closed through applying a pressurized medium to the shutter channel (pressurizing channel), and the channel is opened through releasing a pressure of the pressurized medium. | 03-20-2014 |

| 20160082439 | SPRING-LESS MULTI-POSITION MICRO-FLUIDIC VALVE ASSEMBLY - A springless rotary shear that produces compression forces by utilizing the stiffness properties of polymer seals. The valve is designed to produce an effective spring load, with inherent sealing force, by deflecting polymer elements whose response depends on stiffness that is governed by each component's elastic modulus and geometry. A stator seal protrudes thousandths of an inch beyond a stator seal housing. When a stator is fastened down to the stator seal housing the clamping forces are transmitted to the stator seal, rotor seal, shaft adapter, bearings and housings, and the assembly is deflected to a flush position, resulting in a sealing force between the rotor and stator seal. The transmitted sealing force is as a function of the stiffness of each component and the protrusion distance of the stator seal above the mating surface prior to fastening the stator. | 03-24-2016 |
