There are provided a hydrodynamic bearing assembly and a spindle motor including the same. The hydrodynamic bearing assembly includes: a sleeve including a shaft hole to have a shaft rotatably installed therein; and a cover member covering the shaft hole at a lower portion of the shaft hole in an axial direction, wherein an inner surface of the sleeve is provided with depression parts depressed in an outer diameter direction between upper and lower portions of the sleeve and portions in which radial bearings are formed, such that the portions in which the radial bearings are formed are provided with bearing closure adhesion parts allowing the portions in which the radial bearings are formed to be closer to the shaft than portions other than the portions in which the radial bearings are formed.

Hydrodynamic bearing assembly and spindle motor including the same

Provided herein is a plasma display panel. The plasma display panel comprises a front substrate, a rear substrate opposite to the front substrate and having address electrodes formed thereon, a lattice-shaped partition wall formed between the front substrate and the rear substrate, a phosphor applied to a discharge space partitioned by the partition wall, and a plurality of scanning electrodes and common electrodes formed in intersection regions of the partition wall and extending perpendicular to the front substrate. The plasma display panel has a sufficient aperture ratio, and thus has enhanced light emitting efficiency. The scanning electrodes and the common electrodes formed in the intersection regions of the partition walls have a vertical construction, thereby effectively preventing the phosphor from being damaged by the plasma. Discharge uniformly occurs at the outer periphery of the discharge cell, thereby inducing effective excitation of the phosphor.

Plasma display panel with display electrodes formed in intersecting portions

Disclosed herein is a laminated filter with improved stop band attenuation, which is adopted in devices using a radio frequency, such as communication systems and/or broadcasting systems. The laminated filter forms cross capacitive coupling as feeding lines of input lead and/or output lead are coupled to a resonator pattern, and enhances an attenuation characteristic of stop band. Also, the laminated filter is minimized if feeding lines of the input lead and output lead are aligned in different layers, and the positions of the attenuation poles are easily controlled by adjusting the feeding line length.

The present invention relates to a test pattern for measuring a contact resistance and method of manufacturing the same. In order to confirm that a contact resistance suitable for a semiconductor device before an actual process for manufacturing the device is performed, the present invention designs a test pattern for measuring the contact resistance depending on a design rule of a line contact actually applied to an actual device. At this time, a first line contact region and a second line contact region are formed between a word line so that a line contact region can form a pair; a plurality of sources are formed in the first line contact region and a plurality of sources are formed in the second line contact region wherein neighboring sources are connected by diffusion layers so that the first line contact region and the second line contact region can be electrically connected; and a plurality of line contact patterns are formed so that the plurality of the sources can be electrically connected by every two in each of the first and second line contact regions wherein the line contact pattern formed in the first line contact region and the line contact pattern formed in the second line contact region are alternately positioned. Therefore, the present invention can allow current for measuring the resistance sequentially along the first line contact region and the second line contact region to measure the line contact resistance in which the contact resistance in every source portion is considered.
