A manufacturing method of an array substrate includes the following steps. A gate electrode and a gate insulator layer are successively formed on a substrate. A semiconductor layer, an etching stop layer, a hard mask layer, and a second patterned photoresist are successively formed on the gate insulator layer. The second patterned photoresist is employed for performing an over etching process to the hard mask layer to form a patterned hard mask layer. The second patterned photoresist is employed for performing a first etching process to the etching stop layer. The second patterned photoresist is then employed for performing a second etching process to the semiconductor layer to form a patterned semiconductor layer. The etching stop layer uncovered by the patterned hard mask layer is then removed for forming a patterned etching stop layer.

A thin film transistor (TFT) including a gate, a gate insulator, an oxide semiconductor channel layer, a source, and a drain is provided. The gate insulator covers the gate, while the oxide semiconductor channel layer is configured on the gate insulator and located above the gate. The oxide semiconductor channel layer includes a first sub-layer and a second sub-layer located on the first sub-layer. An oxygen content of the first sub-layer is lower than an oxygen content of the second sub-layer. The source and the drain are configured on a portion of the second sub-layer. In addition, a fabricating method of the above-mentioned TFT is also provided.

A reversible ratchet mechanism for ratchet tools comprises a positioning portion the middle section of which is formed with a concave U groove. Two sides of the U groove are each formed with a receiving groove to which a wedge flake is wedged. An elastic part is provided in the U groove to elastically push open the wedge flakes. A reversible ring is set around the positioning portion, the inner circumference of which is formed with two stoppers that may drive the wedge flakes to turn. A ratchet is set around the positioning portion, the inner side of which is formed with a gear wedging the wedge flakes. Thus, when turning an angle, the reversible ring may drive one of the wedge flakes to release from the gear and thus make the ratchet clutch in a direction.

A lead frame structure comprises a side rail, a first paddle, a second paddle, a plurality of leads, and an downset anchor bar. The first paddle is connected to the side rail via at least one first tie bar, and the second paddle is connected to the side rail via at least one-second tie bar. The first paddle and the second paddle separated from each other are used to define an area to support a chip. These leads set on the side rail expends toward to the chip supporting area. One end of the downset anchor bar is connected to the side rail, and the other end of the downset anchor bar has a protrusion portion which is between the first paddle and the second paddle and is downset from the side rail.

A ratchet wrench able to automatically adjust engaging tooth number according to extent of torsion includes a ratchet block having two ends respectively extending to form an extension portion able to be optionally pushed and stuck between a ratchet ring and the resisting surface of a ratchet moving groove. The engaging surface of the ratchet block is a concave arcuate surface, and the ratio of the radius of the concave arcuate surface and the radius of the ratchet ring is between 1.017 and 1.033. Thus, when the ratchet block bears high torsion, the extension portion will be pushed toward the ratchet ring and the resisting surface of the ratchet moving groove to be pushed by the resisting surface to increase mutually engaging tooth number of the ratchet block and the ratchet ring, thus enabling the ratchet block to automatically adjust engaging tooth number according to extent of torsion.
