Abstract: An exhaust gas denitrifying system having a noise-reduction structure includes a reactor in which a chemical reaction that converts nitrogen oxides included in exhaust gas into nitrogen by denitrifying the nitrogen oxides using a catalyst takes place. The reactor includes a catalytic filter unit coated with a catalyst and provided with a plurality of through-holes through which exhaust gas passes; and a noise-reducing unit for removing noise from the exhaust gas denitrified by the catalytic filter unit. The reactor denitrifies the nitrogen oxides, and simultaneously reduces the noise, thus reducing the size of the exhaust gas denitrifying system.

Abstract: Disclosed herein are a clothes dryer and a control method thereof in which a drying time is adjusted according to wool content during a drying cycle of a wool course. Wool content of woolen textiles is judged by sensing a dryness of the woolen textiles during a drying cycle of a wool course, and a drying time is adjusted according to the wool content, thereby minimizing contraction or deformation of the woolen textiles while satisfying the range of a target dryness set by wool mark standards. Further, only a high-capacity heater is driven during the drying cycle of the wool course, thereby allowing an internal temperature of a rotary drum to keep the optimum temperature without contraction or deformation of the woolen textiles.

Abstract: Disclosed is a pen-shaped optical mouse. The optical mouse has an optical fiber on the optical path of illuminating light, and an optical fiber bundle on the optical path of reflected light, respectively. The optical system of the optical mouse is realized irrespective of the optical paths and their lengths, showing a good image-transmitting feature to transmit good image to an image sensor. An image is input to the image sensor through an end of an optical tip where the image directly contacts a reflecting surface, which enhances the accuracy of the pen-shaped optical mouse since there is no change in the location of a mouse pointer or a focal length in spite of the change in the angle between the pen-shaped optical mouse and the reflecting surface.
