  • Patent number: 7833813
    Abstract: The present invention provides a method of manufacturing a TFT array panel in a cost-effective manner. The method includes: forming thin film transistors each having a gate electrode, a source electrode, and a drain electrode; forming an insulating layer on the thin film transistors; forming a first conductive layer electrically connected to the drain electrodes on the insulating layer; forming a second conductive layer on the first conductive layer; forming a photoresist layer including first portions and second portions thinner than the first portions; selectively etching the second conductive layer with a first etchant by using the photoresist layer as an etch blocker; and selectively etching the first conductive layer with a second etchant by using the photoresist layer and the second conductive layer as etch blockers.
    Type: Grant

  • Patent number: 6647658
    Abstract: A novel “Y” shaped fishing rod support for a novel semi-automatic fishing is comprised of, including but not limited to, an anchoring pole, a straight means of partially cut-out metal pipe consisting the upper part of the fishing rod support, a fishing rod holder guide, a fishing rod holder pivotally engaged in between the “Y” shaped cleavage that is formed between the upper part of the fishing rod support and the fishing rod holder guide, a spring which connects the fishing rod holder and the vertical upper part of the fishing rod support, and an electric trigger operated by a fisherman. The lower part of the straightening means is constructed of a narrow metal pipe. The upper part of the straightening means is constructed of a metal pipe, which is larger in diameter than the metal pipe consisting the lower part of the straightening means.
