Abstract: The present invention relates to a one-directional Velcro comprising a hook and a loop by using the principle of the moment of force, the principle of the inclination-friction and elasticity, etc. An existing fastening tool such as a Velcro tape, an automatic length adjustment buckle, a rotation hook-type buckle, and a saw-type short length adjustment buckle is hard to miniaturize while maintaining strong fastening force. A fastening device which can be satisfactorily used for various technology fields is rear. According to the present invention, a hook needle set (16) mostly made of a high strength and high elasticity alloy material is joined to a buckle frame (31) having a safety protrusion (65) and is formed to be joined to not only a common fabric loop but also an arch-type loop (22) of the present invention according to the thickness and the size of the hook needle. An end portion of a needle tip (14) is formed as short as possible. The surface of the needle tip is processed by high frequency heat treatment and thus is round, sleek, hard, and elastic, and yet is not easily curved or bent. When the hook needles and the loops interact with each other, the hook needles slide between randomly twisted threads, are joined, and do have plastic deformation. Therefore, the one-directional Velcro and loop can be industrially used for various technology fields such as various garments, bags, hats, tents, products for leisure sports and mountain climbing, military products, medical devices for measuring blood pressure, fastening devices, etc.

Abstract: The present invention relates to a method and an apparatus for controlling a cylinder deactivation pattern of an engine. The method for controlling a cylinder deactivation pattern of an engine, which includes a plurality of cylinders and selectively deactivates some of the cylinders, comprises the steps of: (a) setting first and second cylinder deactivation pattern driving modes having different cylinder deactivation patterns such that some of all cylinders in the engine are switched to a deactivation state during operation; (b) performing an all-cylinder driving mode which sprays fuel to all cylinders in the engine at the same time when the engine is started; (c) switching to the first cylinder deactivation pattern driving mode set in step (a), when a required torque value from a driver is smaller than a preset reference torque value during the all-cylinder driving mode, and accumulating first cylinder deactivation pattern driving time; and (d) switching to the second cylinder deactivation pattern driving mode set in step (a), when the first cylinder deactivation pattern driving time accumulated in step (c) is longer than a preset first reference driving time. Therefore, according to the present invention, a warm-up driving time for a cooled cylinder can be reduced, which results in an improvement in fuel efficiency. Also, it is possible to prevent the engine from being driven at a specific cylinder deactivation pattern, which effectively prevents a deactivated cylinder from being cooled down excessively.
