Title: Multi sampling tube device having the suction sampling tube
Inventor: KIM YOUNG IL
IPC: G01N1/14
Filed: 2005-12-23
Abstract: A multi sampling tube device expanding a suction type oxygen sampling tube is provided to detect the concentration of exhaust gas by changing the structure of the suction type sampling tube for simultaneously measuring the concentration of oxygen in a furnace. A multi sampling tube device expanding a suction type oxygen sampling tube includes a flow induction pipe(40), an SUS protection pipe, a Zr oxygen sensor(13a), and a Zr oxygen sensor(13b). The flow induction pipe generates a negative pressure by a suction generating high speed flow. The SUS protection pipe generates an induced compulsory flow to suck the exhaust gas in the interior of the furnace through the negative pressure generated in the flow induction pipe. The Zr oxygen sensor measures the concentration in the SUS protection pipe.

Title: 3d self-measurement system for the curved surface
Inventor: WOO SANG HYUK
IPC: G01B11/24
Filed: 2005-12-29
Abstract: A 3D self-measurement system for a curved surface is provided to enable accurate measurement by outputting error information through comparison of measured data with a CAD drawing of a curved member. A 3D self-measurement system for a curved surface includes a first measuring instrument(100), a second measuring instrument(200), a multi-axis robot(300), a location checking device(400), and a data processing unit(500). The first measuring instrument performs first measurement of low precision for generating a measuring route, and generates the measuring route required for secondary measurement by modeling a surface of a curved member from first measurement data. The second measuring instrument performs measurement of high precision with moving along the measuring route generated by the first measuring instrument, and generates a mold line from the modeled data by modeling the surface of the curved member through the measurement data of high precision. The multi-axis robot moves the second measuring instrument along the measuring route. The location checking device checks locations of the first and second measuring instruments in real time. The data processing unit calculates error data of the curved member by comparing image data and location data inputted from the first and second measuring instruments with pre-inputted CAD data of the curved member.
