A method for forming dual gate electrodes using a damascene gate process is disclosed. A disclosed method comprises: growing a first gate oxide layer on a semiconductor substrate; performing a thermal treatment for a first gate oxide layer; removing a predetermined part of the first gate oxide layer until the top surface of the semiconductor substrate is exposed; growing a second gate oxide layer as a thin oxide layer on the exposed semiconductor substrate, thereby making the first gate oxide layer as a thick oxide layer; depositing polysilicon on the entire surface of the semiconductor substrate and forming dummy gates through a photolithography and an etching processes; forming sidewall spacers on the lateral faces of the dummy gates; forming source and drain regions in the substrate under both sides of the dummy gates; removing the dummy gates and the second gate oxide layer; forming an insulating layer where the second gate oxide layer is removed; performing a thermal treatment for the insulating layer; filling polysilicon for gate electrodes where the dummy gates were removed; and planarizing the resulting structure until the gate electrodes are exposed.

The present invention relates to a composition containing sHSPs for prevention of protein degradation and a composition for two-dimensional (2-D) gel electrophoresis. Furthermore, the present invention relates to the improved method of 2-D gel electrophoresis, which is characterized by using sHSPs. According to the present invention, decreasing of protein spots was prevented in the 2-D gel electrophoresis, thereby obtaining 2-D gel with much more protein spots.

A method and apparatus for detecting a defective disk for a hard disk drive. The method includes placing a disk into a tester so that a first side of the disk is adjacent to a first head of the tester and a second side of the disk is adjacent to a second head. First data is read from the first side of the disk, and second data is read from the second side of the disk. The disk is then flipped so that the second side is adjacent to the first head and the first side is adjacent to the second head. Third data is read from the first side. Fourth data is read from the second side. A first area between a curve generated from the first data and a curve generated from the third data is calculated. Likewise, a second area is calculated between a curve generated from the second data and a curve generated from the fourth data. An average of the first and second areas is then calculated and used to detect a defective disk.

The object of this invention is to provide a device for regulating the flow rate of an intravenous medical solution during an injection using an intravenous drip unit. The device has a housing (10) mounted to a hose (300) to allow the flow of the solution from a solution container (200) into the vein, and a control member (20) rotatably assembled with the housing to regulate the flow rate of the solution. The housing has first and second seats (11, 12) communicating with inlet and outlet ports, and the control member has first and second bosses (21, 22) seated in the first and second seats. An arc-shaped solution path (23), a radial channel (24) and an annular groove (25) are formed on the control member to regulate the flow rate of the solution in accordance with an adjusted angle of the control member relative to the fixed housing.

A method for dynamic in-situ characterization of in-plane and out-plane thermal drift of a hard disk drive head suspension is provided. A first data track is written. Amplitude and amplitude modulation of the write data signal are measured and track center is determined. Data tracks are then written for a selected time period. Amplitude and amplitude modulation of the write data signal is measured and a new track center of a last data track is determined. Any difference between the track center of the first data track and the track center of the last data track represents in-plane drift. The amplitude and amplitude modulation of the two write data signals is compared and any difference between the measured values is proportional to out-plane drift.

The present invention relates to a method for producing middle-chain-length polyhydroxyalkanoate (MCL-PHA) using a maoC gene. The producing method of MCL-PHA according to the present invention comprises the steps of transforming a microorganism with the maoC gene to give a transformant, the microorganism being deleted of a fadB gene and containing a PHA synthase gene; culturing the transformant in medium containing a C6-10 carbon source; and obtaining PHA consisting of monomers with 6-10 carbon atoms. When the maoC gene whose function has not yet been established is used according to the present invention, high quality PHA with a higher number of carbon atoms than the prior PHA can be produced at a higher efficiency.
