Abstract:
Provided is a hollow-fiber membrane module comprising a submodule inside which raw water is circulated and water treatment is carried out, and a piping unit which is connected to the submodule and through which the raw water and air and treated water flow, such that flow rates can be increased and energy consumption can be minimized through the circulation of a fluid.
Abstract:
In an anisotropic conductive adhesive containing a conductive particle, the conductive particle includes a resin particle that is provided with a cavity formed therein and a conductive layer surrounding a surface of the resin particle. The cavity is formed by mixing the resin particle with a reactant and partially removing the reactant from the resin particle. Thus, the conductive particle may readily absorb an external pressure, thereby providing an improved malleability to the conductive particle.
Abstract:
Disclosed herein are an automatically replaceable apparatus for collecting byproducts in semiconductor producing equipment and a control method thereof. The apparatus includes several trap units mounted to a vertical shaft at regular angular intervals and rotating in response to a driving direction of a servo motor. Upper and lower plates support the vertical shaft, and connect byproduct inlet and outlet ports, cleaning-water supply and discharge ports, and dry-gas supply and exhaust ports to the respective trap units. Trap and plate coupling means are extended at normal times to air-tightly seal gaps between the upper and lower plates and the trap units, and contracted when the trap units are rotated in a predetermined direction for the replacement. The servo motor is mounted to a lower surface of the lower plate and rotates the trap units within a predetermined angular range. A control unit controls the operation of the components.
Abstract:
A slide type portable communication terminal capable of automatically slide-moving a display unit on a body unit upwardly or downwardly according to a user's desired mode such as a general mode or a camera activation mode. The terminal comprises a body unit, a display unit slidably mounted at a front surface of the body unit, a guide unit operating with the display unit and the body unit for guiding slide-movement of the display unit, a driving unit for moving the display unit, and a switching unit for sensing motion of the display unit and controlling the driving unit to move the display unit, wherein upon the switching unit sensing the display unit being manually moved in a desired direction, the switching unit controls the driving unit to automatically drive the display unit in the desired direction.
