PURPOSE: An anti-reflection film, a polarizing plate, and an image display device are provided to improve a brightness uniformity and achieve a low cost and a low reflectance, by improving components of a high refractive index layer, which constitutes the anti-reflection film.

CONSTITUTION: An anti-reflection film comprises a clear hard coating layer, a medium refractive index layer, a high refractive index layer, and a low refractive index layer over a transparent support. The high refractive index layer contains titanium oxide and binder as main component. The high refractive index layer has a refractive index of about 1.70 to 1.85 and a layer thickness of about 40 to 70 nanometers. The medium refractive index layer has a refractive index of about 1.55 to 1.70, and the low refractive index layer has a refractive index of about 1.35 to 1.45.

PURPOSE: A method and a system for enforcing a security policy through a security VM(Virtual Machine) are provided to enforce security of a message received through the network, transaction received by a transaction processor, and an application offering an API(Application Program Interface).

CONSTITUTION: An instruction repository(128) stores instructions enforcing the security policy. A data repository(129) stores data of the security policy. A parameter repository stores parameter of a system call. A processor engine(127) determines whether the system call violates the security policy by executing the instruction of the instruction repository with the data of the data repository and the parameter of the parameter repository. The instruction enforcing the security policy is compiled from high level language representation of the security policy.

PURPOSE: An apparatus and a method for exposing images are provided to detect meandering generated by migration of a recording stage, and compensate distortion of image depicted on a recording medium by irradiating light beam from the medium of the stage, and relatively displacing the recording head and the stage to expose image on the medium.

CONSTITUTION: The exposure apparatus comprises: a detection part that detects position meandering in a migration direction and a crossing direction to a stage face of a recording stage which is generated by migration of the recording stage; a memory part that memories and stores displacement data of the position meandering detected by the detection part; a shifting part that shifts individual image pixels formed by image data based on the displacement data remaining in the memory part; and an exposure control part that governs the exposure to a recording medium based on the image data of the shifted image from the shifting part. The exposure method comprises the steps of: pre-memorizing the displacement data for position meandering detected by the detection part in the memory part; shifting image pixels formed by the image data on the basis of the displacement data; and controlling exposure to the recording medium based on the shifted image data.

PURPOSE: A perpetual mobile is provided to produce cheap, efficient and clean energy, so that oil prices can be stabilized, extraordinary phenomena such as global warming and abnormal climate can be prevented, and destroyed environment can be recovered.

CONSTITUTION: A perpetual mobile comprises a major gear(1), a minor gear(2), a balance weight(4), a minor static gear(3), and a major static gear(5). Four or more minor gears including the balance weight are symmetrically mounted to the major gear having a wheel form. As the major gear planarly rotates, the minor gears are accordingly rotated. As the major gear is three-dimensionally rotated, the minor gears adjust a position of the balance weight, so that center of gravity thereof is continuously biased to a certain direction, thereby keeping rotation of the perpetual mobile. A centroid displacing rotation board is constructed by combining the major and the minor gears, the balance weight, and the minor static gear. One or more centroid displacing rotation boards are connected to enable both planar rotation and three-dimensional rotation.

PURPOSE: A method for manufacturing a UHF(Ultra High Frequency) RFID(Radio Frequency IDentification) tag is provided to realize a fast bonding process by quickly and simply bonding an antenna to a chip, and integrate many chips by making volume of the tag, as multiple short UHF antennas, instead of a loop antenna widely occupying a substrate, are directly bonded to the chip.

CONSTITUTION: The chip having multiple bumps at an upper side is placed to an upper part of the substrate(102). While installing a cutter between the bumps, an edge of the cutter is placed to the specific height of the upper part of the substrate(106). After the cutter cuts the UHF antenna extended to a lengthwise direction by making the UHF antenna moved down to a cutter side in a state crossing the UHF antenna over the edge, a cut part is connected to the bump by continuously descending the edge(110).
