Disclosed is a method for making a film assembly used in a PDP filter positioned on the front surface of a PDP, a film assembly manufactured by the method, and a PDP filter using the film assembly. The method includes providing a roll of an EMI film formed on a surface of a long transparent polymer resin film with a predetermined spacing and mounting the wound roll of the EMI film on a first feed roller; providing a roll of at least one long transparent functional film capable of covering at least partially the effective screen portions of the EMI film and mounting the wound roll of the functional film on a second feed roller which is spaced a predetermined distance from the first feed roller; and integrating the EMI film with the functional film by feeding them into a gap between the first and second compression rollers.

Disclosed is a tension resistant structure. The tension resistant structure includes a TCP/COF (tape carrier package/chip on film) tape having first and second sprocket holes formed at upper and lower ends of the TCP/COF tape while forming an interval of a predetermined pitch therebetween and supporters provided at both sides of the first and second sprocket holes of the TCP/COF tape so as to absorb tension being applied to the TCP/COF tape. The supporters are installed at both sides of the TCP/COF tape, so the TCP/COF tape made from Upilex/Kapton is prevented from being cut off while the TCP/COF tape is being fed or retrieved.

Disclosed are a server system for performing communication over a wireless network and a communication method thereof. The server system comprises at least one client device and a server device for performing a state monitoring operation or a control operation for the client device over the wireless network. When a data packet is sent, the server device begins to send a following packet by variably applying a transmission rate according to a network transmission state when a leading packet has been completely transmitted. Because a transmission rate can be set appropriately to the network state, the number of unnecessary retransmissions can be reduced. Therefore, transmission delay can be avoided and stable and rapid wireless communication can be achieved.

Techniques and circuit configurations for fine phase adjustments, for example, in a delay-locked loop (DLL) circuit are provided. Multiple phase signals may be generated from a single current source by selectively coupling one or more delay elements to an output node of the current source. The delay elements may vary the timing of a signal generated by switching the current source.

摘要:
A method for characterizing deposited film on a substrate within a processing chamber during processing is provided. The method includes determining voltage-current characteristic for a probe head when measuring capacitor is set at a first capacitance value. The method also includes applying RF train to the probe head when measuring capacitor is set at a capacitance value greater than first capacitance value. The method further includes providing an initial resistance value and an initial capacitance value for the deposited film. The method yet also includes employing initial resistance value, initial capacitance value, and voltage-current characteristic to generate simulated voltage-time curve. The method yet further includes determining measured voltage-time curve, which represents potential drop across the deposited film for one RF train. The method more over includes comparing the two curves. If the difference is less than predefined threshold, employ initial resistance value and initial capacitance for characterizing the deposited film.
