摘要： A method and an apparatus for marking an identification mark on a wafer. After the wafer is aligned, a laser beam is radiated onto a predetermined portion on the wafer so that the identification mark is engraved on the wafer. While the laser beam is being radiated, a gas blows towards the predetermined portion on the wafer so as to remove the particles which are created on the surface on the wafer caused by the radiation of the laser beam. A collecting and exhausting section is provided to collect and exhaust the gas that is mixed with the particles.

摘要： A rotor reducing stress concentration generated by centrifugal force, the rotor having interference fit between a reinforcing ring and the external circumference of a rotor cylinder or rotor cylinder having a hole, wherein the rotor preliminarily rotates at high speed so that the rotor is plastic-deformed in advance, so that less plastic-deformation occurs even when the rotor rotates at high speed compared to the case where plastic deformation is not performed in advance.

摘要： Disclosed is a large capacity hollow-type flywheel energy storage device. The energy storage device includes a hollow shaft, a vacuum chamber receiving the hollow shaft, a flywheel having a predetermined weight and disposed at an inner edge of the vacuum chamber, and a hub connecting the flywheel to the hollow shaft and disposed in the vacuum chamber to be rotatable together with the flywheel. A superconductive bearing and an electromagnet bearing are disposed inside and outside the hollow shaft, respectively, such that magnetic forces thereof can be shielded from each other. Thus, magnetic interference between the superconductive bearing and the electromagnet bearing is shielded by the magnet shield interposed therebetween, thereby preventing rotation loss by stabilizing a structural mechanism during rotation while improving design adaptability.

摘要： Provided is a flywheel structure of an apparatus for storing energy (particularly electric power), and more particularly, to a flywheel structure of an energy storage apparatus, which allows stable operation since upper and lower thrust collars are installed on an upper and lower faces of a rotor or a hub of the flywheel, respectively and the system thus can be balanced after assembly is completed in a state that all parts including the thrust collars are assembled and which can control vibration effectively since axial displacement is controlled at upper and lower sides of the center of gravity. To this end, the present invention provides a flywheel structure of an energy storage apparatus comprising a central shaft connected to a bearing for restricting a radial direction and an electric motor, a rotor of a high strength for storing rotational energy, a hub for connecting the central shaft and the rotor, and a thrust collar mounted on the central shaft, wherein upper and lower thrust collars are installed on upper and lower face of the rotor or the hub, respectively.
