| 20110053094 | METHOD FOR FABRICATING ROLLER MOLD FOR NANOIMPRINTING - A method for fabricating a roller mold is provided, including providing a roller substrate, wherein the roller substrate is a cylinder and has a curved surface. An inorganic resist layer is formed over the curved surface of the roller substrate. A laser exposure device is provided for irradiating the inorganic resist layer with a focused laser, causing phase change of the inorganic resist layer at exposed regions. The inorganic resist layer in the exposed regions is removed to form a nano-pattern over the roller substrate. | 03-03-2011 |

| 20100002568 | High-density information storage apparatus - A system is provided. The system includes an information storage medium including a substrate and a plurality of pit trains formed on the substrate at a track pitch between 0.64 and 0.67 micrometers. The system further includes a pickup head having a numerical aperture of around 0.6 and a wavelength of around 650 nanometers. The system has a tangential tilt margin between 0.54 and 0.68 degrees, and a radial tilt margin between 0.68 and 0.83 degrees when a jitter of the system is about 10%. | 01-07-2010 |
| 20100033281 | PRECISE MULTI-POLE MAGNETIC COMPONENT - A method is provided to manufacture a precise multi-pole magnetic component for using in magnetic encoders. A special layout of the circuit pattern is designed and formed on a printed circuit board (PCB). Alternate and regular magnetic field is induced according to Ampere's law after a current flowing through the circuit on the PCB. The multi-pole magnetic component with fine magnetic pole pitch is achieved by forming the high-density circuit patterns on a substrate using the PCB technology. | 02-11-2010 |

| 20080203504 | Magneto-resistance transistor and method thereof - A magneto-resistance transistor including a magneto-resistant element which may function as an emitter and a passive element which may function as a collector. The base may be interposed between the passive element and the magneto-resistant element, thereby coupling the passive element with the magneto-resistant element. A magnetic field of a given strength may be applied to at least a portion of the magneto-resistant transistor, the given strength determining a resistance in the at least a portion of the magneto-resistant transistor. Thus, by adjusting the given strength of the magnetic field, the resistance may be adjusted. Therefore, different emitter current inputs may be achieved with a fixed voltage. Further, a base current may vary with a controlled variation of the emitter current input. | 08-28-2008 |
