Abstract: A scan driver includes: a first transistor having a first electrode coupled to an output scan line, a second electrode coupled to a first power line, and a gate electrode coupled to a first node; a second transistor having a first electrode coupled to a first clock line, a second electrode coupled to the output scan line, and a gate electrode coupled to a second node; a third transistor having a first electrode coupled to the first node, a second electrode coupled to a first input scan line, and a gate electrode coupled to a second clock line; and a fourth transistor having a first electrode coupled to the second node and a second electrode and a gate electrode, which are coupled to a second input scan line, wherein the first input scan line and the second input scan line are different from each other.

Abstract: An apparatus for manufacturing a display device includes a plurality of working tables, a plurality of arm modules, and a rotator. The plurality of working tables are spaced apart from each other in a first direction and are configured to support a target board. The plurality of arm modules are arranged in the first direction and spaced apart from the plurality of working tables in a second direction intersecting the first direction. The rotator is connected to the plurality of arm modules and configured to rotate about a rotation axis extending in the first direction.

Abstract: The present invention relates to a signal sequence peptide for the improvement of extracellular secretion efficiency of a heterologous protein in E. coli. More particularly, the present invention relates to a gene construct for the improvement of extracellular secretion efficiency of the said heterologous protein in E. coli, which comprises a polynucleotide encoding a recombinant protein composed of the heterologous protein linked to C-terminal of the signal sequence peptide represented by SEQ. ID. NO. 3. The present invention contributes to the improvement of extracellular secretion efficiency of a recombinant protein, so that it can be effectively applied to the production of a recombinant protein.

Abstract: A computer having a main board provided with a BIOS-ROM for booting the computer and a CPU. A removable storage unit having a casing, a readable and writable memory accommodated in the casing and having a data storing part and a code storing part, and a plug provided at the casing for transmitting data to/from the memory to the computer. The computer also having an interface part provided at the main board and to which the plug of the removable storage unit is removably connected; and a controller controlling the booting of the computer when a user code output from the code storing part and received through the interface part is equal to a unit code stored in the BIOS-ROM. With this configuration, the present invention provides both security and additional storage to the computer.

Abstract: A power supply apparatus and method in a computer system, which can protect an auxiliary memory device and data stored in the auxiliary memory device, are provided. The power supply apparatus in a computer system having an auxiliary memory device includes a power switch for switching on or off power supplied to the computer system, a power controller for generating a power off signal when it is detected that the power switch is turned off and drive active signals generated by the auxiliary memory device are deactivated, and generating a power on signal when it is detected that the power switch is turned on, and a switch mode power supply for converting alternating current power into direct current power and supplying the converted power to each apparatus included in the computer system, when the power on signal is received from the power controller, and cutting off the direct current power to the each apparatus, when the power off signal is received from the power controller.

Abstract: A portable computer comprises a housing, a microphone holder mounted in the housing so as to be inserted into or projected from the housing, a groove formed in the housing to receive the microphone holder, and a microphone mounted on the free end of the microphone holder, wherein the microphone holder is projected from the groove when using the microphone. The microphone may be used with the microphone holder received in the groove. Preferably, the microphone holder may be made of a flexible material. The microphone holder may further comprise a first holder attached to the housing in the groove by a hinge, and a second holder attached to the first holder by a hinge to be folded over the first holder. In this case, the microphone is mounted on the free end of the second holder.

Abstract: An enhanced feature connector for an overlay board transmits and receives digital data from a video graphics array (VGA) feature connector and analog data from a video graphics array connector using a single connector. The overlay board uses an enhanced feature connector for receiving both video graphics array digital feature data and analog red, green, blue (R.G.B.
