    摘要： Provided is a method of fabricating a nanoimprint mold which can form sub-100 nm fine pattern structures. The method includes forming patterns on a first substrate using an E-beam lithography (EBL) process, and transferring the patterns formed on the first substrate to a second substrate using a nanoimprint lithography (NIL) process to complete an NIL mold. Accordingly, the method can easily fabricate the nanoimprint mold at low costs on a quartz or glass substrate, which is not suitable for an EBL process to produce sub-100 nm patterns, by utilizing the advantages of the EBL process with a resolution of tens of nanometers.

    摘要： A superconducting rotating machine having a cooler for a rotator is provided. The superconducting rotating machine includes a rotator wound with a superconducting coil, a stator enclosing the rotator and separated therefrom by a predetermined gap, the cooler having a cold head directly attached to the rotator and at least one compressor connected with the cold head, and a flexible coupling disposed between the cold head and the compressor and enabling a cryogenic refrigerant to flow therein. The cold head is directly connected to the rotator, and the cold head and the compressor are driven using the flexible coupling, so that it is possible to prevent vibration of the compressor and enhance cooling efficiency by thermally separating the cryogenic cold head from the compressor.

    摘要： An apparatus and a method for driving a voice coil actuator of a camera are disclosed. In the apparatus for driving a voice coil actuator of a camera, when an input shaping execution unit generates a shaping signal using a resonance frequency of the voice coil actuator to output a drive control signal subjected to input shaping, a drive circuit unit controls an operation of the voice coil actuator connected to a rear end according to the drive control signal using the shaping signal as an initial input. The shaping signal is used for removing resonance of the voice coil actuator and may be one of a 2-step shaping signal, a multi-step shaping signal having 4 or more steps, a linear shaping signal, a toggle shaping signal and the like.

    摘要： Provided is a high-temperature fuel cell separator. The fuel cell separator includes a fuel gas flow path containing hydrogen, an oxidant gas flow path containing mainly an oxygen component being supplied from an oxygen/nitrogen separator of a system and participating in electrochemical reactions, and a cooling gas flow path containing a nitrogen component to remove heat produced upon power generation of a fuel cell. Such a configuration provides a high-temperature fuel cell separator which is capable of improving efficiency of an overall fuel cell system through improved performance of a fuel cell stack due to increased oxygen partial pressure and which is also capable of improving reliability of the fuel cell stack through inhibition of the occurrence of a high-temperature region resulting from heat produced upon power generation of a fuel cell, by means of a flow of cooling gas containing a nitrogen component.
