An apparatus for operating an auto-shutter in an air-conditioner is provided, which includes an external casing in which a louver frame having an exit is installed in the inner portion of the upper end thereof, an auto-shutter movable between an opened position opening the exit and a closed position closing the exit, and a shutter driver driving the auto-shutter. The shutter driver includes a driving motor which is rotatable forwardly and backwardly, a screw-rod shaped rotational rod which is coupled with the driving motor and thus rotates, a bushing which is coupled with the rotational rod and ascends and descends along with the rotational rod, a slider one end of which is coupled with the auto-shutter and the other end of which is coupled with the bushing, an angular rotating unit which makes the driving motor and the rotational rod rotate by a predetermined angle when the auto-shutter moves from the opened position to the closed position, and a rotational rod guider which guides and supports rotation of the rotational rod, wherein guide rails are formed on both side surfaces in the louver frame in order to guide the auto-shutter. Also, the shutter driver may include a driving motor which is provided to provide a driving force for opening and closing and moving the auto-shutter and is rotatable forwardly and backwardly, a screw-rod shaped rotational rod which is coupled with the driving motor and thus rotates, a bushing which is coupled with the rotational rod and ascends and descends along with the rotational rod, and a slider one end of which is coupled with the auto-shutter and the other end of which is coupled with the bushing, wherein guide rails are formed on both side walls in the louver frame in order to guide the auto-shutter. Likewise, without employing an auto-shutter driving system which is opened and closed by the rack-and-pinion mutual operation in a conventional rack and pinion structure, the auto-shutter is opened and closed by a new system having a shutter driver which includes a screw-rod shaped rotational rod, a bushing, a slider, and a driving motor, thereby driving the auto-shutter more effectively in view of driving power used.

A lithium ion secondary battery is provided. The lithium ion secondary battery generally comprises an electrode assembly, a container for accommodating the electrode assembly; and an electrolyte. The electrode assembly comprises two electrodes having opposite polarities and a separator. The separator comprises a porous membrane comprising clusters of ceramic particles. The porous membrane is formed by bonding the particle clusters with a binder. Each particle cluster is formed either by sintering or by dissolving and re-crystallizing all or a portion of the ceramic particles. The ceramic particles comprise a ceramic material having a band gap. Each particle cluster may have the shape of a grape bunch or a lamina, and may be formed by laminating scale or flake shaped ceramic particles.

An output driver has an output multiplexor and an output current driver. The output multiplexor receives a data signal and outputs a q-node signal. The output current 5 river receives the q-node signal and drives a bus based on the q-node signal. The output multiplexor processes the data signal in various ways to generate the q-node signal. The output current driver is responsive to current control bits to select a amount of output drive current. In addition, the output multiplexor is controlled such that the output impedance of the output current driver is maintained within a predetermined range.

A central control system for airconditioner(s) and a method for controlling the same. The central control system can centrally control a plurality of airconditioners connected to the same communication network. In the system, a protocol converter connected to a central controller converts a communication standard of a signal communicated between the airconditioners and the central controller into another communication standard, acquires connection state information by scanning connection state information of individual airconditioners, and transmits the acquired information to the central controller, such that a manager can correctly monitor an airconditioner state using the central controller, resulting in the implementation of a reliable control system.

An SOI MOSFET having a body contact for preventing the floating body effect is provided. The body contact is a trench perforating a body and a buried oxide layer to a semiconductor substrate. The trench is filled with a conductive material to electrically connect the body to the semiconductor substrate. Impurity ions are implanted into a predetermined region of the semiconductor substrate in contact with the lower portion of the body contact to form an ohmic contact. In the SOI MOSFET, an additional metal interconnection line is not needed to supply power to the body. Also, malfunction of a circuit due to stray capacitance of a contact can be prevented.
