  • Publication number: 20190374939
    Abstract: A liquid separation device comprises a tubular container and a piston. The tubular container has an accommodating space for storing a liquid. A front end of the tubular container is gradually reduced to form a conical body. A column is protruded from a front end of the conical body. An opening is formed at a rear end of the tubular container. The piston is movably placed inside the tubular container from the opening and is made of flexible and elastic material which will expand and tighten the tubular container. A fixing column is disposed on the piston to facilitate the pressure on the fixed column to control the movement of the piston.

  • Publication number: 20190341389
    Abstract: A semiconductor device includes: active regions arranged in a first grid oriented substantially parallel to a first direction; and gate electrodes arranged spaced apart in a second grid and overlying corresponding ones of the active regions, the second grid being oriented substantially parallel to a second direction, the second direction being substantially orthogonal to the first direction. The first gaps are interspersed correspondingly between neighboring ones of the active regions. For a flyover intersection at which a corresponding gate electrode crosses over a corresponding active region and for which the gate electrode is not functionally connected to the corresponding active region, the gate electrode does not extend substantially beyond the corresponding active region and so does not extend substantially into a corresponding one of the first gaps.

  • Patent number: 10352698
    Abstract: Disclosed is a composite hydrological monitoring system, in which a counterweight component and a test component are respectively connected to both opposite ends of a strip and a plurality of sensors are disposed at different vertical positions. Accordingly, the scour depth can be measured by sensing the location of the counterweight component, whereas the water level and/or flow velocity can be determined by signals from the sensors. When the counterweight component moves downward with sinking of the riverbed, the strip would be pulled down and thus causes the test component to present a change in mechanical energy. Accordingly, the sinking depth can be measured by sensing the change of the mechanical energy. Additionally, since the water level variation would cause signal changes of the sensors arranged in a row along a vertical direction, the change of water level can be determined accordingly.

  • Patent number: 7762158
    Abstract: A self-locking device for a table elevating screw includes a rotatable disk disposed on a screw having a nut thereon, a wedged body disposed on the rotatable disk, an outer cover moveably disposed on the rotatable disk and the wedged body and a stop plate disposed on the outer cover. When the rotatable disk rotates in relation to the screw in a direction or a reverse direction, the wedged body ascends or descends in relation to the rotatable disk, maintaining a gap between the stop plate and the outer cover or generating a frictional force therebetween. By the frictional force occurred when the screw rotates in a single direction, the self-locking device can achieve a precise self-locking device for the screw in a lifting/lowering positioning task.
