摘要： Provided is a fabricating method of a pattern, which includes preparing a first substrate having a first width and a first thickness, stretching the first substrate and preparing a second substrate having a second width and a second thickness, forming a base layer made of a material of a pattern which will be formed on the second substrate, removing a predetermined region of the base layer and forming a first pattern having a first line width and a first height on the second substrate, and removing a tensile force applied to the second substrate to restore the second substrate back to being the first substrate and forming a second pattern having a second line width and a second height on the first substrate. Fineness of a line width can be achieved by forming the first pattern in a state in which the substrate is stretched, contracting a line width of the first pattern while restoring the stretched substrate, and forming the second pattern having a contracted line width on the restored substrate such that high integration can be achieved.

摘要： Disclosed are a charge sensitive amplifier capable of minimizing a variation in a signal voltage of an output signal by applying a bias direct current to a gate of a feedback transistor, and a radiation sensor including the same. According to the charge sensitive amplifier and the radiation sensor including the same, it is possible to minimize a variation in a signal voltage of a charge sensitive amplifier output signal by applying a current, which is formed by mirroring a current bias circuit designed to be insensitive to PVT variations, to a gate of a feedback transistor. Furthermore, it is possible to reduce a variation in charging time and enable high-speed sensing by charging the signal voltage to the level of a common voltage VCOM by using a constant current supplied through a bandgap reference (BGR) circuit.

摘要： The present invention relates to a MIG welding system including: operating a vision module and a welding device; capturing a thermal image of a welding part using an IR thermal camera connected to the vision module, converting the image into a video signal, and transmitting the video image to the vision module; detecting whether there is slag through the vision module; determining whether the detected slag is fixed when the slag is detected through the vision module; and analyzing the position of the slag and calculating a coordinate value when it is determined that the detected slag is fixed. Even if the slag is not checked with the naked eye, the operator can determine the position of the fixed slag which is not checked with the naked eye through the calculated coordinate values.
