A liquid crystal display is provided. The liquid crystal display includes a pixel array having a plurality of pixels in a matrix on a substrate. First and second pixels are adjacent to each other along a first direction. The first and second pixels each include first and second switching elements. A first common gate line extends in a second direction different from the first direction and is commonly connected to the first and second switching elements. First and second data lines extend in the first direction and are connected to the first and second switching elements, respectively.

The hydrocarbon-assisted, selective catalytic reduction of NOx constituents in lean-bum engine exhaust is benefited by passage of the exhaust over a staged catalyst bed comprising a first stage of an alumina-supported silver catalyst for oxidation of NO to NO2 and partial oxidation of added hydrocarbon to an aldehyde. Downstream of the silver catalyst is a second catalyst selected for the reaction of hydrocarbon and aldehyde species with NO2 to reduce it to nitrogen. Gamma-alumina and BaY zeolite are examples of suitable second stage catalysts.

A thermistor, which is to be mounted on a PCB, for protecting other circuit elements is disclosed. Electrode patterns separately formed on both surfaces of a film resistance element are respectively shaped into two parts which are engaged to each other with a non-conductive gap interposed therebetween. Thus, a Tombstone phenomenon caused by asymmetric structure may be fundamentally prevented. Grooves are formed in both sides of the thermistor, and connection portions for electrically connecting the electrodes formed on both surfaces of the thermistor are formed through the inside of the grooves or through the sides except the grooves. Thus, though a crack arises in the connection portion, it is possible to prevent the crack from being propagated to the entire connection portion along the side of the thermistor.

A thermistor of which resistance is changed depending on temperature and a secondary battery to which the thermistor is attached are disclosed. The thermistor is attached to an object via a lead which is made of different kinds of materials. The lead is configured so that a part of the lead to be united to the thermistor electrode is mainly made of the same material as the electrode and a part of the lead to be united to the object is mainly made of the same material as the surface of the object. Thus, the thermistor may be simply attached to the object only using the ultrasonic welding, thereby remarkably reducing junction inferiorities.

The present invention relates to a display device, and more particularly to a display device in which gate lines and a main gate driver can be repaired. The display device includes a plurality of pixels respectively including a switching element, a gate line connected to the switching element, and first and second gate drivers respectively including a plurality of stages that are interconnected and sequentially generate output signals. Any one of the stages of the first gate driver and any one of the stages of the second gate driver are connected to the same gate line. In this manner, gate drivers that generate the same output are disposed in one gate line on the left and right sides. It is therefore possible to repair disconnected gate lines without using a laser.

摘要:
The present invention relates to a preparation method using a fusion expression partner. The method includes preparing a polynucleotide encoding a fusion expression partner selected from the group consisting of SlyD (FKBR-type peptidyl prolyl cis-trans isomerase), Crr (glucose-specific phosphotransferase (PTS) enzyme IIA component), RpoS (RNA polymerase sigma factor), PotD (Spermidine/putrescine-binding periplasmic protein), and RpoA (RNA polymerase alpha subunit), and an expression vector linking a polyDNA fragment of a heterologous protein, preparing a transformant by introducing the expression vector into a host cell, inducing the expression of a recombinant protein by culturing a transformant, and obtaining the expression. In the preparation method of the recombinant protein, the heterologous protein may enhance the water-solubility and folding of the recombinant protein, overcome the limitations about the water-solubility and folding which the conventional fusion expression partners have, and be used widely in the production of pharmaceutical and industrial proteins.
