Abstract: PURPOSE: A method for forming a thin film transistor is provided to maintain interface among a buffer oxide film, an amorphous silicon layer, and a first silicon oxide film, and improve the interface characteristics of the buffer oxide film and the amorphous silicon layer. CONSTITUTION: A buffer oxide film(202), an amorphous silicon layer, and a first silicon oxide film are sequentially deposited on an insulating substrate(200) in a vacuum state. An active layer(205) is formed by etching the amorphous silicon layer and the first silicon oxide film. A second silicon oxide film and a conductive film for generating a gate are sequentially formed on the buffer oxide film to cover the residual first silicon oxide film. A gate(213) is formed by etching the conductive film. A gate insulating film(216) is formed by etching the residual first silicon oxide film and the second silicon oxide film. An LDD(Lightly Doped Drain) area(205a) and a source/drain area(205b) by injecting ion into the amorphous silicon layer. The amorphous silicon layer including the LDD area and the source/drain area is crystallized. A passivation film is formed with contact holes exposing the source/drain area.

Abstract: PURPOSE: A feeding pipeline is provided to prevent in an early stage disorders of a drive motor caused by overloading, and to provide a predetermined tension to a disc wire without limiting the tension adding position of the disc wire and to detect the wire breaking in the early stage even when a wire breaking occurs. CONSTITUTION: Drive units for driving each of disc wires are installed on several line corners. A tension-giving device(A) is installed with a stretchable pipe assembly(22) comprised by connecting between an inner pipe(20) and an outer pipe(21) with a shock absorber(23). The device A gives tension to the disc wire through a drive gear of the drive unit by moving the outer pipe in the elongation direction(T) by pressure of the shock absorber when it is put in the middle of the line. When the outer pipe moves more than a certain distance in the elongation direction of the pipe assembly, a limit switch detects the broken state of the wire and stops all drives of the drive gears.

Abstract: PURPOSE: An assembling method of a seat rail for a vehicle and a processing apparatus for assembling are provided to prevent failure or deformation of a bearing by assembling the bearing in forming the uniform rolling groove through simple process. CONSTITUTION: A seat rail of a vehicle is formed by assembling an upper rail, a lower rail and a bearing. The lower rail is placed inside the upper rail before assembling the seat rail, and a fitting rod(30) is inserted forcibly to the insertion position of the bearing ball. A rolling groove is formed longitudinally in the upper rail and the lower rail to move the ball of the bearing, and the bearing is combined. The fitting rod with the same diameter as the bearing ball is made of material stronger than the upper rail and the lower rail. The ball of the bearing is combined accurately at the regular pressure.
