Disclosed is an anode for a lithium secondary battery. The anode includes a current collector in the form of a wire and a porous anode active material layer coated to surround the surface of the current collector. The three-dimensional porous structure of the active material layer increases the surface area of the anode. Accordingly, the mobility of lithium ions through the anode is improved, achieving superior battery performance. In addition, the porous structure allows the anode to relieve internal stress and pressure, such as swelling, occurring during charge and discharge of a battery, ensuring high stability of the battery while preventing deformation of the battery. These advantages make the anode suitable for use in a cable-type secondary battery. Further disclosed is a lithium secondary battery including the anode.

The present invention relates to a scanning microscope using an I/Q-interferometer. The scanning microscope includes an I/Q-interferometer which demodulates the phase change and amplitude change induced on the probe beam to provide the I- and Q-signals, an XY scanner, a scanner driver, a precision motion stage controlling the displacement of the sample along the direction parallel to the direction of the probe beam, a motion stage driver, a focusing/collimating device, and a computer. The computer transfers control commands to the scanner driver for scanning the XY scanner, receives I- and Q-signal provided from the I/Q-interferometer, processes the I- and Q-signal to obtain the corresponding phase and amplitude values at each scanning point, calculates error signal for maintaining constant phase during the scanning, and transfers commands to the motion stage driver for the precision motion stage to compensate for phase changes caused by surface morphology during the scanning.The scanning microscope performs a multilayer scanning or a constant phase scanning to extract information for the surface or inside of the sample.

The present invention relates to a polynucleotide that is active to an acetyl glutamate synthase and acetyl ornithinase which are associated with ornithine or arginine biosynthesis from Corynebacterium glutamicum. The present invention also relates to a polypeptide encoded by said polynucleotide, a recombinant vector comprising said polynucleotide, to a transformant obtained by introducing said recombinant vector to a host microorganism for producing L-ornithine or L-arginine, and transforming the recombinant vector, and to a method for producing L-ornithine or L-arginine by culturing said transformant. The activity of the transformant of the present invention to an acetyl glutamate synthase and acetyl ornithinase is increased as compared to an intrinsic activity, and thus L-ornithine or L-arginine can be produced, at a high yield rate, from the transformant of the present invention.

Disclosed herein is a system and method for managing identity. The system includes a mobile terminal, a web server, and a service terminal. The mobile terminal includes a smart card on which a management server for managing user identity is mounted. The web server generates the user identity and provides the generated identity to the management server over a wired/wireless network. The service terminal receives a required identity from the mobile terminal using Near Field Communication (NFC).
摘要:
A two stage reciprocating compressor includes a casing. A first compressing unit is disposed in the casing and includes a first piston and a first cylinder, the first compressing unit being driven by a reciprocating motor to linearly reciprocate the first piston in the first cylinder to suck in and compress gas. A second compressing unit is disposed in the casing and includes a second piston and a second cylinder, the second compressing unit being driven by vibration of the first compressing unit to linearly reciprocate the second piston in the second cylinder to suck in and compress gas. A vibration transfer member transfers the vibration from the first compressing unit to the second compressing unit. The first and second compressing units extend in parallel and face in the same direction, the second compressing unit being located adjacent to a suction passage of the first compressing unit.
