Abstract:
PURPOSE: A vacuum gauge using carbon nanometer tubes is provided to exactly measure a vacuum pressure by allowing electrons to be emitted. CONSTITUTION: A vacuum gauge using carbon nanometer tubes includes a vacuum vessel(100), a base, a carbon tube layer(300), a grid(400), and a collector. The vacuum vessel(100) has a connection port in such a manner that gas molecular is introduced. The base is formed on an inner surface of the vacuum vessel(100). The carbon tube layer(300) has a plurality of carbon nano-tubes and emits electrons according to applying negative voltage. The collector is arranged on the grid(400) by a predetermined interval and collects positive ions stemmed from impact of electrons.

PURPOSE: An apparatus and a method for diagnosing safety of a bridge are provided to simply and effectively diagnose the bridge and to conveniently repair and maintain the bridge. CONSTITUTION: A bridge consists of a plurality of bridge upper plates connected to each other. Lower portions of the bridge upper plates are supported by a pier. An elastic supporter(300) is positioned between the pier and the bridge upper plates so as to apply flexibility to the bridge upper plates when external force is applied to the bridge upper plates. The elastic supporter(300) elastically supports the bridge upper plates against vertical load applied to the bridge upper plates. The elastic supporter(300) has upper and lower plates(310,320) and a supporting member(340) interposed between the upper and lower plates(310,320).
Abstract:
PURPOSE: A force compensating apparatus having a dual coil structure is provided to maximally utilize mechanical characteristics by precisely compensating for an error generated during a measurement process. CONSTITUTION: A force compensating apparatus includes a magnetic force generation module(30) having a first coil(32) and a second coil(33). Current is applied to the first and second coils(32,33) through an open-loop and a control loop, respectively. A leverage(20), which is varied depending on load applied to a weight pan(10), is compensated by means of magnetic force generated from the first coil(32). A main rod is fixed at a lower portion of the weight pan(10). One end of the leverage(20) linked to a side of the main load. First and second support rods(11,12) are positioned at upper and lower portions of the leverage(20) in parallel to each other.
