Abstract: A method for forming a dual polygate of a semiconductor device is provided to improve the characteristic and reliability of the semiconductor device by using an SOG(Spin-On Glass) layer instead of a mask pattern. A gate insulating layer(112) is formed on a semiconductor substrate(100) including a PMOS region and an NMOS region. An N+ polysilicon layer(114) is formed on the gate insulating layer. An SOG layer for exposing the PMOS region is formed on the N+ polysilicon layer. The N+ polysilicon layer exposed by the SOG layer is changed into a P+ polysilicon layer(118). The SOG layer is removed. A metal-based layer(120) and a hard mask layer(122) are formed on the N+ polysilicon layer and the P+ polysilicon layer. The hard mask layer, the metal-based layer, the N+ polysilicon layer, the P+ polysilicon layer, and the gate insulating layer are etched.

Title: Lens barrel
Inventor: HAYASHI KUNIHIKO
IPC: G02B7/04
Filed: 2004-09-30
Abstract: A lens barrel that is small-sized and can be produced at low cost by compactly constructing an inside lens mechanism. In the lens barrel, the number of shafts can be reduced because a guide shaft (61) serves as the common guide shaft. Further, a guide shaft (63) is formed only in a movement region of a zoom movement body (22) and a coil unit (70) is disposed in a space behind the region. Accordingly, the entire lens barrel can be compactly constructed. On the other hand, the guide shaft (61) and a guide shaft (62) are constructed separately, and this results that the length of a sleeve section (21a) of the zoom movement body (22) and the length of a sleeve section (41a) of a focus movement body (42) are sufficient and that a slide length of each movement body is sufficient. As a result, the lens barrel is compact, and accurate and stable operation of each movement body can be realized.

Title: Method for forming wavy nanostructures
Inventor: SMIRNOV VALERY KONSTANTINOVICH
IPC: H01L/
Filed: 2004-10-08
Abstract: The inventive method for forming a wavy nanostructure consists in spraying a semiconductor material by means of a flux of molecular nitrogen N2+ ions in such a way that a periodic wavy nanostructure is formed on a material surface and the crests of said nanostructure waves are oriented in a perpendicular direction with respect to the incidence plane of ions. In order to increase the nanostructure amplitude, the additional spraying is carried out by means a flux of O2+ ions on a ionic-bombardment plane which coincides with the plane of bombardment by the nitrogen N2+ ions. The O2+ ion bombardment energy and angle are selected such that the wavelengths of formable wavy nanostructures coincide at a single irradiation by N2+ and O2+ ions. Three variants for forming an ordered wavy nanostructure for arsenide, gallium and silicon structures are also disclosed.

Title: Energized restraining gasket for mechanical joints of pipes
Inventor: COPELAND DANIEL ALBERT
IPC: F16L13/04
Filed: 2003-10-15
Abstract: The present invention may be basically described as a gasket for converting a standard mechanical joint into a restrained mechanical joint without the need for altered configuration of the bell, spigot, or gland of the joint, and without the need for additional fittings or devices. In the practice of the present invention, a standard mechanical joint's bell and gland configuration can be employed to connect a spigot end of one pipe length to the bell end of another pipe length in a restrained relationship, with the restraint based on forces superior to rubber-to- pipe friction. In more particular discussion of the embodiments taught, the invention includes forming the gasket to fit within the bell in such a manner that a void, or gutter, exists during rest, into which void the gasket compresses, which in turn influences the rotational motion of the segment. In this manner, the configuration of the gasket influences the timing and extent of rotation throughout the process of securing the gland to the bell.

Inventor: GUPTA ALOK KUMAR
IPC: H04L5/06
Filed: 2005-01-28
Abstract: A timing estimation system and methodology are provided. In particular, a first pilot is employed in conjunction with three acquisition stages. In the first stage, an attempt is made to observe the leading edge of the correlation curve associated with the first pilot symbol. In the second stage, a determination is made to confirm a leading edge was detected in the first stage by attempting to observe a trailing edge of the correlation curve. Furthermore, during this second stage, a frequency loop is updated to account for frequency offset. The third stage is for observing the trailing edge of the curve if it was not already observed in stage two. Upon detection of receipt of the first pilot, a second pilot can subsequently be employed to acquire fine symbol timing.
