摘要： PURPOSE: To provide a liquid outflow control valve of low price and small power consumption by fixing both ends of a beam opening/closing a through hole by curving according to change of temperature on a base plate formed with the through hole, and controlling the curved displacement of the beam by a temperature control means. CONSTITUTION: A super small sized valve device 10 for controlling a fluid flow is provided with a base 12 having a through hole (outlet orifice) 26 forming a first flow route, and a beam 72 arranged so that the flexible middle part is piled on the hole 26 is fitted to the vicinity of the base plate 12. The beam 72 generates curved displacement as a result of heat expansion, and the hole 26 is opened/closed by the curved displacement of the beam 72. For controlling heating of the beam 72, heating resistances 96, 98 as a temperature controlling assembly is provided, and they are integratedly sandwiched between the first base plate 12 and a dish-like second base plate fitted to the lower part through a peripheral combined layer 68.

摘要： PURPOSE: To provide an integrated pressure/flow regulator which can regulate the pressure of a fluid with high accuracy. CONSTITUTION: The pressure at an output port 648 is regulated by bringing condenser plates 666 and 668 closer to each other or farther from each other in accordance with the pressure change at the port 648 by utilizing the deflection of a diaphragm 674 caused by the pressure change.

摘要： PURPOSE: To improve air characteristics and heat characteristics of a microminiature valve by arranging a monocrystal substrate having plural main surfaces, a flow via and a valve seat, an armature interfering with a flow of fluid and plural displacement means for displacing the armature between opening and closing positions. CONSTITUTION: In this microminiature valve 10, a monocrystal substrate 12 is provided with opposed plural main surfaces 38, 30, a flow via 14 extending in the other main surface 30 from one main surface 38 and a valve seat 28 including a seat surface having the inner periphery forming an orifice to the flow via 14 by extending from a plane of one main surface 38. An armature 18 is provided with a plane having a closing position and an opening position for disturbing a flow of fluid to the flow via 14 from the orifice by contacting with the seat surface of the valve seat 28. The armature 18 is selectively displaced between the opening and closing positions by plural displacement means 20, 22. By the way, an inclined inside surface for increassing the cross-sectional area as the flow via 14 separates from the seat surface is formed on the valve seat 28.

摘要： PURPOSE: To obtain reliable fluid control in an atmosphere, wherein there is an electrical noise and vary the focal length with high precision by providing a light-transmissive substrate and a specific light-transmissive substance. CONSTITUTION: The pattern of a resistance heater of a Pyrex(R) wafer 420 has some spacer bored without any obstacle to an optical path, which passes through the wafer 420, a substance confined to a thin-film chamber 422, and a thin film 424. The Pyrex(R), the substance confined to the film chamber 422 and the substance of the thin film 424, all have refractive indexes. Then the focal length of the lens can be varied by varying the curvature of the lens, and this is attained by raising or lowering the temperature of the substance confined to the thin film 422 and varying the curvature of the silicon nitride thin film 424. Namely, the varifocal lens can modulate the quantity of light which is incident on an optical fiber guide by controlling the temperature of the substance, confined to the thin-film chamber 422.

摘要： PURPOSE: To provide a microvalve that can be closed positively and be assembled easily. CONSTITUTION: This microvalve, which comprises a sculptured silicon substrate 10 held between two cover layers 31 and 32 each consisting of one or more layers, has a valve plate 20 positioned to have surfaces respectively facing these two cover layers 31 and 32 in the region of an inlet 33 and an outlet 34 in a generally symmetrical fashion. The valve plate 20 is connected to the silicon substrate 10 by webs 15, and is shaped as a closure member near the inlet 33 and/or the outlet 34. Electrodes 35 and 36 are provided on the respective cover layers 31 and 32 opposite the valve plate 20 so that the microvalve can be electrostatically actuated with the valve plate 20 serving as counter electrode for these electrodes 35 and 36.

摘要： PURPOSE: To enable mass production by disposing two valve plate members to face each other, providing a valve seat on one valve plate member, and providing a valve member on the other for achieving high precision tightness by complementary formation of them even when the two valve plate members are of a relatively low precision. CONSTITUTION: A valve member 12 and a valve port 14 of the same size and of mutually complementary form are provided on a valve plate member 10 of machining starting material. A separation layer 16 is then formed on the valve plate member 10, a cover plate is provided on the valve plate 10, and a die 18 is formed in a casting method, for example, so its form is a correct replica of the valve plate member 10. The separation layer 16 is removed, a back surface of the die 18 is polished, and a valve member 20 and a valve part 22 are formed, where the valve part 22 has the same form as the valve port 14. Orientation of corresponding sealing surfaces of the valve plate members 10, 20 is correctly formed by the sealing surface of the valve plate 10 to achieve high precision matching, thereby the valve plate member 10 can be manufactured at a relatively low precision.

摘要： Methods and systems for processing polynucleotides (e.g., DNA) are disclosed, A processing region includes one or more surfaces (e.g., particle surfaces) modified with ligands that regain polynucleotides under a first set of conditions (e.g., temperature and pH) and release the polynucleotides under a second set of conditions (e.g., higher temperature and/or more basic pH). The processing region can he used to, for example, concentrate polynucleotides of a sample and/or separate inhititors of amplification reactions from the polynucleotides Microfluidic devices with a processing region are disclosed.
