Abstract: Methods and apparatus for finishing an edge of a glass sheet are described. The edge of the glass sheet is finished using two grinding wheels mounted on spindles so that the edge of the grinding wheels chamfer the edge of the glass sheet during relative movement of the grinding wheels and the glass sheet.

Abstract: A device for gripping a substrate without contact with which the substrate can be more securely transported. In the device, a housing cap has an air inlet in the upper surface and a lower opening, the lower opening communicating with the air inlet such that air introduced through the air inlet exits through the lower opening. A contour of the lower opening in its vertical cross section is convexly rounded such that the introduced air is guided along a horizontal undersurface of the housing cap. A nozzle is disposed in an inner hollow space of the housing cap, and has an inclined surface such that the width of the nozzle gradually decreases in the direction from the undersurface of the nozzle to the upper surface of the nozzle adjacent to the air inlet. The undersurface of the nozzle is at a predetermined distance from the inner surface of the housing cap. An ultrasonic shaker applies ultrasonic vibration to the housing cap.

Abstract: Disclosed herein is a quantitative analysis method for measuring a target element in a specimen using laser-induced plasma spectrum. More particularly, the present invention relates to a method for analyzing a composition ratio of a target element by calculating peak intensities when peaks overlap each other in a spectrum, and a method for selecting a peak of a wavelength at which the highest precision and reproducibility are secured through linearity of a correlation plot of the peak intensities and a value by dividing a standard deviation value of calibration curve data (peak intensity ratios) by a slope when an internal standard method is used for quantitative analysis of a target element.

Abstract: An apparatus and a method for inputting a character using user's motion is provided. When a user's hand makes a motion, a character input pattern is recognized from the motion, a character to be input is determined by comparing the recognized character input pattern with character input pattern information which predefines various character input patterns and corresponding characters, and the determined character is displayed.
