    Abstract: PURPOSE: A phase-shift driving type micro pump and a method for manufacturing the same are provided to fabricate the phase-shift driving type micro pump through a simple micro-machining technique. CONSTITUTION: A phase-shift driving type micro pump includes a pair of manual valves and a phase-shift driver. The manual valves are formed by overlapping two wafers having an aluminum flap valve. The aluminum valve has a cantilever shape having a thickness of few micrometers. The phase-shift driver includes a driving thin film(8) and a micro heater(7). An operating liquid chamber(3) is formed at a lower portion of the driving thin film(8). The micro heater(7) is formed at a lower substrate(10). A heater and a wire are covered with an insulation layer. Two injection ports(6) are provided to inject operating liquid into the lower substrate(10).

    Abstract: マイクロバルブ・デバイスは、本体と、本体に対して移動するように支持されたバルブ要素と、バルブ要素を正常な移動範囲で移動させるようにバルブ要素に動作可能に接続されたアクチュエータとを含む。 移動制限構造は、バルブ要素およびアクチュエータのうちの少なくとも一方と動作可能に協働して、破壊応力の限界を超えることによって本体、バルブ要素、またはアクチュエータが破壊するのを防止するために、バルブ要素またはアクチュエータが正常な移動範囲の外に移動する距離を効果的に制限する。 こうした移動制限構造を有するマイクロバルブを形成する方法も開示する。

    Abstract: PROBLEM TO BE SOLVED: To provide a microelectromechanical system (MEMS) valve device having advantages of quick operation, large valve force and large displacement while consuming minimal power. SOLUTION: The MEMS valve device includes a substrate 20 having an aperture 70 formed therein, a substrate electrode 40, and a movable membrane 60 located on the aperture 70 and having an electrode element layer 62 and biasing element layers 64, 66. At least one resiliently compressible dielectric layer 50 is provided to ensure electrical isolation between the substrate electrode 40 and the electrode element layer 62 of the movable membrane 60. In operation, voltage difference is established between the substrate electrode 40 and the electrode element layer 62 of the movable membrane 60 to move the movable membrane 60 relative to the aperture 70 to thereby controllably adjust the portion of the aperture 70 covered with the movable membrane 60.
