Provided is a microelectromechanical system (MEMS) actuator in which a cantilever piezoelectric actuator and a comb actuator are combined to perform dual shaft drive. The MEMS includes: a stationary comb fixed on a substrate; a movable comb disposed separately from the substrate; and a spring connected to the movable comb and the substrate to resiliently support the movable comb, wherein the movable comb includes a piezoelectric material layer in a laminated manner to be perpendicularly moved by a piezoelectric phenomenon and laterally moved by an electrostatic force to the stationary comb, whereby the MEMS actuator can be used in a driving apparatus of an ultra-slim optical disk drive since the movable comb is made of a piezoelectric material to simultaneously perform focusing actuation to a Z-axis as well as planar actuation.

Provided are a structure for an optical device and method of fabricating the same. The structure includes: a light scattering layer producing nanoparticles due to externally provided thermal energy; a protective layer protecting the light scattering layer; and a capping layer disposed between the light scattering layer and the protective layer. As the light scattering layer is formed of nitride-oxide, an energy gap is increased to make the structure suitable for a high-speed electronic circuit, and a desired stoichiometric ratio can be easily obtained. Also, the capping layer prevents crystalline mismatch, thus the non-uniformity of elements is inhibited to maintain a stoichiometric state. As a result, a high-integrated high-speed electronic circuit, which is excellent in uniformity and reproducibility, can be easily embodied.

A local SONOS structure having a two-piece gate and a self-aligned ONO structure includes: a substrate; an ONO structure on the substrate; a first gate layer on and aligned with the ONO structure; a gate insulator on the substrate aside the ONO structure; and a second gate layer on the first gate layer and on the gate insulator. The first and second gate layers are electrically connected together. Together, the ONO structure and first and second gate layers define at least a 1-bit local SONOS structure. A corresponding method of manufacture includes: providing a substrate; forming an ONO structure on the substrate; forming a first gate layer on and aligned with the ONO structure; forming a gate insulator on the substrate aside the ONO structure; forming a second gate layer on the first gate layer and on the gate insulator; and electrically connecting the first and second gate layers.

The present invention relates to an apparatus for focusing particle beams using a radiation pressure capable of obtaining the same flow amount and a narrower particle beam width with respect to the particle size and a higher numeral density. It is possible to form the particle beams by applying the radiation pressure to the particles with respect to the flow condition that cannot form the particle beams with respect to the set particle sizes. There is provided an apparatus for focusing particle beams using a radiation pressure, comprising an orifice part that is provided at a predetermined portion of the flow tube, and a lens having a hole with a predetermined diameter for thereby focusing the particle flow into a particle beam and applying a radiation pressure to the flow particles; and a light source supply part (A) provided at a portion opposite to the discharge outlet of the mixing tube.

Described herein are inbred B6 ES cell lines that exhibit high developmental capacities and have a number of advantages over ES cell lines already available. First, they can be used for gene targeting and have a high percentage of germline transmission when injected into diploid host blastocysts (˜50-80%). Second, these ES cell lines can successfully be used to generate live pups by tetraploid blastocyst complementation, producing a high percentage (15-20%) of mice that are entirely inbred B6 ES cell derived. Third, these ES cells lines can be used to rapidly generate mice that are homozygous for a gene of interest. These advantages indicate that the inbred B6 ES cells provided here facilitate the rapid generation of inbred B6 mouse models in a cost-effective and efficient manner.
