A syndiotactic polystyrene composition is improved which exhibits improved crystallization rate. The improved syndiotactic polystyrene composition contains (a) a syndiotactic polystyrene; and (b) a nucleating agent which is selected from the group consisting of two types of compounds represented by the following formulas, respectively: ##STR1## In Formulas I and II, the radicals R.sub.1 and R.sub.2, which can be the same of different, are C.sub.1 to C.sub.5 alkyl groups, X is a halogen group, preferably a bromide group, and n is an integer from 1 to 5. In the present invention, the nucleating agent is provided at 0.01 to 5 part, by weight, per 100 parts, also by weight, of the syndiotactic polystyrene resin. An example of Formula I compound is 2-hydroxybenimidiazole, and an example of the Formula II compound is bis(phenylbromide) methane.

An output buffer of a source driver is disclosed. The output buffer includes a buffer input, a buffer output, a differential input stage, a bias current source, an output stage, a compensation capacitor, and a comparator. The output stage and the comparator are both operated between an analog supply voltage (AVDD) and a ground voltage (AGND). The comparator compares an input voltage and an output voltage and outputs a control signal to the bias current source according to the compared result to control a bias current outputted by the bias current source to enhance the slew rate of the output buffer.

A multi-chip stacked package primarily comprises a chip carrier, a first chip disposed on the chip carrier, a plurality of die-attaching bars, a second chip stacked on the first chip by the adhesion of the die-attaching bars, and a plurality of bonding wires electrically connecting the first chip to the chip carrier. The die-attaching bars are formed on the first chip in a specific pattern and have an adhesive surface away from the first chip for adhering the second chip. The bonding wires have a loop height lower than the adhesive surface in a manner that specific sections of the bonding wires are embedded in the corresponding die-attaching bar from the adhesive surface. Accordingly, the die-attaching bars can modify and fasten the bonding wires in advance to avoid collapse and deformation of the bonding wires during stacking of the second chip and encapsulating processes.

A method for manufacturing a quantum-dot element utilizes a reaction chamber for evaporating or sputtering at least one electrode layer or at least one buffer layer on a substrate. A substrate-supporting base is located inside the reaction chamber for fixing the substrate. An atomizer has a gas inlet and a sample inlet. More specifically, the gas inlet and the sample inlet feed the atomizer respectively with a gas and a precursor solution having a plurality of functionalized quantum dots, and thereby form a quantum-dot layer on the substrate. The method for manufacturing a quantum-dot element forms a quantum dot layer with uniformly distributed quantum dots and integrates the processes for forming the quantum-dot layer, the buffer layer, and the electrode layer together in the same chamber.

The present invention relates to a mobile jamming attack method applied in a wireless sensor network (WSN) and method defending the same. The mobile jamming attack method is a power exhaustion denial-of-service attack, possesses mobility and self-learning capability and is unable to be defended with existing defending scheme due to its attack to the routing layer of the WSN; the mobile jamming defending method employs multi-topologies scheme to defend the mobile jamming attack so that the affected area is reduced, the base station can still receive reply packets under the attack, and the jammed area can be roughly located and the track of the mobile jammer can be traced.

A method for manufacturing a quantum-dot element is disclosed. The method includes the following steps. First, a deposition chamber having at least one atomizer and a substrate-supporting base is provided. The atomizer is connected to a gas inlet and a sample inlet. Afterwards, a sample solution is prepared composed of a plurality of functionalized quantum dots dispersed in a solvent. Simultaneously, a substrate is placed on the substrate-supporting base in the deposition chamber. Finally, the sample solution and a gas are transferred into the atomizer through the sample inlet and the gas inlet respectively for generating quantum-dot droplets, which subsequently deposit on the substrate in the deposition chamber. The quantum-dot element manufactured by the present invention has a uniform distribution of quantum dots that have a small size and, therefore, the quality of the quantum-dot element can be substantially improved.

A repairing method of a liquid crystal display panel having a gravity defect includes steps of removing the sealant outside the liquid crystal injection hole and providing a first pressure to the liquid crystal display panel. Next, a second pressure is continuously provided to the liquid crystal display panel, and the sealant in the liquid crystal injection hole is removed. Then, a third pressure is continuously provided to the liquid crystal display panel for pressing the liquid crystal out through the injection hole, and the flowed liquid crystal is cleaned out. After that, the liquid crystal injection hole is sealed with a fresh sealant and a fourth pressure is continuously provided to the liquid crystal display panel. Finally, the fresh sealant is cured and the fourth pressure is removed.

A method for generating header and transition flags using the DPD technology and an optical device using the same are disclosed. The method first sets a first and a second threshold levels. Then, the method generates a phase difference signal, i.e. starting a phase detection function to generate a phase difference signal. The method generates a first transition flag signal and a second transition flag signal, wherein the first transition flag signal is enable if the phase difference signal is greater than a first threshold level and the second transition flag signal is enable if the phase difference signal is smaller than the second threshold level. The method then generates a first header flag signal and a second header flag signal according to the transition flag signal. The first header flag signal is enable if the first transition flag signal becomes enable before the second transition flag does, and the second header flag signal is enable if the second transition flag signal becomes enable before the first transition flag does.
