Abstract: Disclosed herein is a composition for plasma electrolytic oxidation (PEO) treatment of magnesium alloy products, which contains a sodium hydroxide (NaOH) solution as a main component, the composition comprising, based on the weight of sodium hydroxide contained in the sodium hydroxide solution: 1-20 wt % of sodium fluoride (NaF); 1-15 wt % of trisodium phosphate (Na3PO4); 1-10 wt % of sodium pyrophosphate (Na4P2O7); 1-20 wt % of aluminum hydroxide (Al(OH)3); 1-20 wt % of sodium fluorosilicate (Na2SiF6); 1-10 wt % of potassium hydroxide (KOH); 1-15 wt % of potassium acetate (C2H3O2K); and 1-10 wt % of rare earth metal powder. The disclosed composition can form a firm, dense and uniform oxide film on the surface of a magnesium alloy product.

Abstract: A slide type communication terminal designed to allow a sliding operation to be smoothly completed by means of a driving unit and a travel-enlarging member. In the communication terminal having a first body and a second body, a driving unit includes a motor and a pinion connected to the motor. A first hinge has a rack gear meshed with the pinion and a travel-enlarging member connected to the rack gear. A second hinge has a contact member protruded therefrom to contact the travel-enlarging member. Rotation of the pinion in response to the drive force of the driving unit is converted into a linear movement of the rack gear, and a distance of the linear movement of the rack gear is enlarged by means of the travel-enlarging member, so that the second body fixed to the second hinge is slid to an enlarged travel distance.

Abstract: An inclined-type mobile communication terminal for opening/closing a main body using a link apparatus is provided. The inclined-type mobile communication terminal includes a first main body, a second main body, a driving unit, and a link unit. The driving unit is fixed to the first main body and provides a driving force required for moving the second main body. The link unit includes a driving link and a driven link. The driving link has its one side fixed to an output terminal of the driving unit and is rotated by the driving force of the driving unit, and has its other side rotatably connected with the second main body to move the second main body. The driven link connects the first and the second main bodies so as to guide a movement of the second main body using rotation of the driving link.

Abstract: A method of compensating sensor data and a method of evaluating an interlock of an interlock system, in which an allowable variation between sensors varying depending on a driving time for a set of equipment, an RF time, the number of wafers, etc. is minimized, thereby enhancing detection reliability of a defective wafer.

Abstract: A method of compensating sensor data used in an interlock system comprises setting a predetermined drift upper limit and a predetermined drift lower limit, creating a reference pattern information about a reference model, creating a sensor pattern information about the sensor data, determining whether the sensor pattern information satisfies the drift upper limit and the drift lower limit, calculating a drift offset according to the reference pattern information and the sensor pattern information when the sensor pattern information satisfies the drift upper limit and the drift lower limit, and compensating the sensor data according to the calculated drift offset.
