Abstract:
The present invention is a method of metal polishing and oxidation film process applied on a metal workpiece. The process comprises (a) providing the metallic workpiece in an electrolysis polishing liquid; (b) a temperature control device controlling a liquid temperature of the electrolysis polishing liquid; (c) a voltage supply device to exercising an operating voltage between the metallic workpiece and the electrolysis polishing liquid; (d) polishing the surface of the metallic workpiece and forming an oxidation layer by regulating the temperature control device and the voltage supply device; and (e) determining a film thickness of the oxidation layer formed on the metallic workpiece according to an operation time, wherein the film thickness is related to a roughness and a color displayed on the metallic workpiece. The metallic workpiece may be dyed together during the polishing process without adding any dyes. The present invention further provides a system of alloy oxidation film process.

Abstract:
An information monitoring and updating method and system for a transport stream is provided. First, a transport stream is received. The transport stream includes a program specific information (PSI) table, and the PSI table is divided into a plurality of sections. Next, by setting a first filtering parameter of a monitor-section filter, the header of each section of the PSI table is filtered out and is then checked whether to be a latest version or not. When all the section headers of the PSI table are of the latest version, each section of the PSI table is filtered by setting a second filtering parameter of a table-section filter.
Abstract:
System and method for improving immersion scanner overlay performance are described. One embodiment is a method of improving overlay performance of an photolithography immersion scanner comprising a wafer table having lens cooling water (“LCW”) disposed in a water channel therein, the wafer table having an input for receiving the LCW into the water channel and an output for expelling the LCW from the water channel. The method comprises providing a water tank at at least one of the wafer table input and the wafer table output; monitoring a pressure of water in the water tank; and maintaining the pressure of the water in the water tank at a predetermined level.
Abstract:
A heat dissipation apparatus includes a retention module (10), a heat sink (20) disposed on the retention module, a fastening cover (23) covering the heat sink, and a plurality of fasteners (30) connected with the retention module and the fastening cover for mounting the heat sink onto a heat generating electronic component (50). The fastener includes a fastening member (31) and an operating member (32). The fastening member has a first end (313) engaged with the retention module and a second end (311) opposed to the first end. The operating member includes a resilient pressing portion (321) pivotably connected with the second end of the fastening member and contacting with the fastening cover, and an operation portion (322) connected with the pressing portion.
Abstract:
A security apparatus for motor vehicles is disclosed, and is featured in integrating all the components into one body as an all-in-one form and in filling resin into the housing of the security apparatus so as to completely cover an electric circuit unit and the interior surface of a siren. The present invention is alternately featured in providing a metal cover covering the externally-exposed surface of the siren for protecting the siren; providing fastening elements each of which has a head hole of special pattern, thereby preventing the security apparatus from being unlawfully dismantled; and providing several detecting modes and power-saving modes, so as to effectively and reliably provide the antitheft function for motor vehicles.
