Disclosed is a method of fabricating an automotive seat cover leather. The method includes a preparing process, a tanning process, a neutralizing process, a retanning process, an elastic material adding process, a dyeing/fatliquoring process, and a surface fixing process. After the leather has gone through the tanning process and neutralizing process, the retanning process adds a tanning agent to the leather. The elastic material adding process adds a silicon-based elastic material to induce elasticity in the retanned leather. The dyeing/fatliquoring process adds a dye to the leather in which the elastic material has been added and adds an anion fatliquoring agent to the leather to provide flexibility. The surface fixing process fixes the elastic material, dye, and fatliquoring agent on and in the leather.

A lithium rechargeable battery in which an anti-rotation groove is integrally formed with a lower recess of a safety vent at a lower surface of a cap plate, and an insulating plate and a terminal plate rest in the anti-rotation groove so that the terminal plate is prevented from rotating when a cap assembly is assembled is provided. In addition, instead of the anti-rotation groove, a resting recess is formed on a lower surface of the cap plate, and the insulating plate and the terminal plate rest in the resting recess, so that the terminal plate is prevented from rotating when the cap assembly is assembled.

A method of forming a semiconductor device having an offset spacer may include forming a gate electrode on a semiconductor substrate. An etch stop layer including a nitride may be formed on the entire surface of the semiconductor substrate having the gate electrode. First spacers may be formed on the sidewalls of the gate electrode. The first spacers may be formed of a material layer having an etch selectivity with respect to the etch stop layer. The etch stop layer may be exposed on the semiconductor substrate on both sides of the gate electrode. Lightly-doped drain (LDD) regions may be formed in the semiconductor substrate using the gate electrode and the first spacers as an ion implantation mask. Second spacers may be formed on the first spacers. Accordingly, a semiconductor device having an offset spacer may be provided.

The present invention relates to a network-based robot system and an executing method thereof. According to an exemplary embodiment of the present invention, predefine environment information is expressed in a universal data model (UDM) described by a linkage that shows a relationship among nodes, each node being an object of a virtual space abstracted by a real physical space. The universal data model is updated based on the context information, event occurrence information is transmitted to a task engine when the context information data value is changed, and the task engine executes a corresponding task through reasoning and invokes an external service. The robot can better recognize the context information by utilizing the external sensing function and external processing function. In addition, the robot system can provide an active service by reasoning the recognized context information and obtaining high-level information.

An overlay mark includes at least one hole array formed on a semiconductor substrate and at least one linear trench adjacent to the hole array. The hole array may be formed adjacent to the linear trench along a predetermined direction. When alignment errors among patterns formed at predetermined portion of the semiconductor substrate are detected, the overlay mark may provide a contrast of light with a desired width and a high level so that alignment errors of patterns formed on the semiconductor substrate may be accurately detected and corrected using the overlay mark.

A method for anti-stain treatment of fabric is disclosed. The method for anti-stain treatment of fabric includes: immersing fabric in an aqueous solution containing a telomerized perfluoroalkyl acrylate copolymer, and a crosslinking agent, such as an isocyanate crosslinking agent; dehydrating the immersed fabric; drying the dehydrated fabric; heat treating the dried fabric; and coating the heat-treated fabric with a flame retardant, such as an acrylic flame retardant, to provide flame retardancy. The method provides a car seat fabric having superior stain resistance, water repellency and oil repellency without degradation of other properties required for the car seat fabric, such as flame retardancy, lightfastness, frictional coloration, or the like. The method is widely applicable to commercially applicable car seat fabrics, including flat woven, flat tricot, double raschel, or the like.
