Abstract: Disclosed is a test socket for inspecting an electronic device that is particular about properties. The test socket for inspecting electric properties of a subject includes a plurality of probes configured to be retractable in an inspection direction; a probe supporter configured to support the plurality of probes so that first ends of the plurality of probes protrudes to contact with an object contact point of a subject; and a printed circuit board (PCB) configured to be placed beneath the probe supporter, be mounted with electronic parts, be formed with holes through which second ends of the plurality of probes pass, include at least one first pad with which at least one second end of the plurality of probes comes into contact and at least one second pad formed on an opposite side to the first pad, and be formed with electric paths extended from the first pad and the second pad and connected to the mounted electronic parts.

Abstract: A test device for testing electric properties of an object. The test device includes an object support unit configured to support an object; a cover unit configured to include a cover body coupled to the object support unit and a pusher supported by the cover body so as to move toward and away from the object; and a pressure adjuster configured to include a multi-stage adjusting cam which is rotatably provided in the cover body while contacting the pusher and has a multi-stage contact pressing portion with contact radii varied depending on rotated angles so that the pusher can be in a moving-back position and be positioned at a plurality of pressing distances from the cover body, and an operation unit which operates the multi-stage adjusting cam.

Abstract: Disclosed is a touch screen panel, including: a glass substrate including an active area and a non-active area; enhancement layers formed on upper and lower surfaces of the glass substrate; sensing patterns disposed on a surface of one of the enhancement layers in the active area; and sensing lines disposed in the non-active area, and electrically connected with the sensing patterns. Here, a side surface of the glass substrate may include a plurality of blunt areas depressed in a shape of a curved surface.

Abstract: A glass-reinforcing composition and method of using the same, the composition including 1 weight % to 20 weight % of hydrofluoric acid, 0.1 weight % to 5 weight % of ammonium fluoride, 1 weight % to 20 weight % of an inorganic acid, an organic acid, or 1 weight % to 10 weight % of an organic acid salt, and a remainder of water.
