Abstract: The present invention relates to a cutting tip for a cutting tool, which is used in cutting or drilling a brittle workpiece such as stone, bricks, concrete, and asphalt and has an excellent cutting speed and a long lifetime, a method of manufacturing the cutting tip, and a cutting tool including the cutting tip. The cutting tip includes an abrasive material and a sintered bonding material, wherein the bonding material is formed of a metal matrix; the metal matrix includes a phase II and/or pore having a certain size at a certain volume fraction; and the phase II is one of a non-metallic inclusion and ceramic. According to an aspect of the present invention, there is provided a cutting tip having excellent cutting speed and a long lifetime at a much lower price.

Abstract: The present invention relates to a method for producing a knitted neck collar, and more particularly to a knitted neck collar prevented from drooping, wherein, when producing a neck collar using a knitted material, a narrow band having excellent elasticity and return force is inserted in the neck collar to prevent the neck collar from drooping, a method for producing the same, and a garment having the same. By the method for producing a knitted neck collar according to the present invention, it is possible to provide a knitted neck collar prevented from drooping even when a garment having the knitted neck collar is repeatedly put on and taken off and washed, thereby maintaining the original shape of the knitted neck collar, due to the fact that an elastic member having the same circumference as a distal end of the knitted neck collar is inserted in the neck collar and can be reliably positioned in the neck collar along the distal end of the neck collar.

Abstract: A display device that does not suffer from blurring or reduction in brightness is presented. The device includes a plurality of pixels, a scan driver, a signal controller, and a data driver. Each pixel includes a light-emitting element and a driving transistor that outputs a driving current to the light-emitting element. The scan driver supplies a scan signal to the pixels. The signal controller generates a first output image signal representing a brightness higher than a reference brightness and a second output image signal representing a brightness lower than the reference brightness. The data driver converts the first output image signal and the second output image signal into a first and second data voltages and alternately supplies the two data voltages to the pixels. This way, the same images are displayed with a first period and a second period having a different brightness levels, achieving an impulsive effect between frames.
