Title: Apparatus and method for a focus position lock device for a projection television lens assembly
Inventor: MITCHELL JOHN DAVID
IPC: G03B21/14
Filed: 2000-05-15
Granted: 2001-05-01
Abstract: An apparatus and method for locking a focus position of lens assembly without causing the lens cell to tilt, comprising: a spacer interposed between the lens cell and the focus mount. The spacer is received into a sleeve that is integral with the focus mount. The sleeve projects radially outward from the focus mount such that the spacer can be raised and lowered radially with respect to the focus mount. The spacer has a cylindrical body with a radial flange at one end. Moreover, the spacer has a cylindrical body with a radial flange at one end. Moreover, the spacer has two ridges that extend downward from a lower surface of the flange, each of which is received into a corresponding groove on the sleeve, thus, reventing the spacer from rotaing within thw sleeve. The spacer also has an upwardly raised rim xtending from an upper surface of the flange. The rim is slidably secured into a slot of the focus mount, which prevents lateral movement of the spacer. Further, a bolt is coupled to the opening within the spacer, such that one end of the bolt is disposed and secured within the spacer and the other end of the bolt extends radially outward through the slot of the focus mount. A nut is secured onto the bolt. After focusing the lens cell assembly, the nut is tightened onto the bolt in order to maintain focus of the lens cell assembly. The tightening of the nut brings an upper surface of the flange of the spacer into frictional engagement with an interior surface of the focus mount, which prevents the tilting of the len cell within the focus mount, thus, maintaining a focus position of the lens assembly.

Title: Bullets for use in training exercises
Inventor: HSIUNG JEN-CHOU
IPC: F42B5/02

Granted: 2001-04-21
Abstract: This invention provides an assembly of a bullet structure, that can be implemented in the training exercises of military and police training, while the exercises can be performed in a highly realistic manner without causing any injures. The assembly includes a bullet, a bullet end plate, a C-clip, and an ammunition cartridge. The bullet is assembled to a support stand of the bullet endplate. The bullet end plate is pressed into the ammunition cartridge. The C-clip is pressed into a bottom recess of the bullet end plate. When the kindling is triggered to ignite the firing agent, part of the combusted and expanded air rapidly penetrates the passageway of the bullet end plate and then drives the bullet forwards. The remaining power is used to restrict the ammunition cartridge such that when the ammunition cartridge recedes, the C-clip expands outwards to impede the ammunition cartridge so as to eject the bullet shell in a smooth manner.

Title: Manufacturing method for eliminating defect of antimony ion implantation region
Inventor: GU WEN-YU
IPC: H01L21/265
Filed: 2001-03-15
Granted: 2004-03-11
Abstract: The present invention is provided to eliminate pit or bubble defect on the antimony ion implantation region when implanting antimony ions on a semiconductor wafer due to the required driving process after implantation. Such a defect will cause dislocation or stack defect in the subsequent process, and thus result in problems of leakage current increasing and reduced yield rate. The method comprises the steps of: first implanting antimony ions into a defined silicon wafer surface; next, after the step of implanting antimony ions, heating the silicon substrate to a first temperature; decreasing the first temperature and holding a constant temperature, and directing oxygen into a reacting chamber; and heating the silicon substrate to a second temperature and closing the gas directed to the reacting chamber, thereby eliminating pit or bubble defect on the antimony ion implantation region due to abnormal oxidization and steps, reducing dislocation and stack defect, and avoiding the generation of leakage current.

Title: Copper alloy interconnections for integrated circuits and methods of making same
Inventor: DUBIN VALERY M
IPC: H01L23/532
Filed: 2001-10-29
Granted: 2005-08-21
Abstract: Formation of copper alloy interconnected lines on integrated circuits includes electroplating copper onto a seed layer wherein the concentration of the doping element or elements in the copper is controlled such that the core portion of the copper interconnect line has a low concentration of the doping element or elements, while surface portions of the copper interconnect line have higher concentrations of the doping element or elements. Copper alloys are plated at different current densities to provide doping element rich interfaces. In this way, electromigration resistance can be improved by having relatively higher doping concentrations at surface portions of an interconnect line while the desired low electrical resistivity of the interconnect is maintained by keeping the interior portions of the interconnect with a substantially lower doping concentration.
