摘要： A magnetic write head for use in a data recording system having first and second magnetic pole, the first pole having a P1 pedestal. An electrically conductive coil passes through a space between the first and second poles for inducing a magnetic flux through the yoke formed by the first and second poles. A bi-layer insulation layer disposed between the poles includes a layer of photoresist for preventing voids and a layer of alumina formed thereover to provide a structural brace to prevent recession of the P1 pedestal during manufacturing operations such as soda blast.

摘要： A method for chemical mechanical polishing (CMP) wafers having high aspect ratio surface topography. A wafer is positioned on a plate. A polishing pad is coupled to a platen. A polishing solution (e.g., slurry) is added between the polishing pad and the wafer. CMP is performed on the wafer by creating a relative movement between the polishing pad and the wafer. The polishing pad removes substantially all residual material from the channels. To accomplish this, the polishing pad has a compressibility of at least 5% at a polishing pressure of about 4 psi.
摘要翻译：一种具有高纵横比表面形貌的化学机械抛光（CMP）晶片的方法。晶片位于板上。抛光垫联接到压板。在抛光垫和晶片之间添加抛光溶液（例如浆料）。通过在抛光垫和晶片之间产生相对移动来在晶片上执行CMP。抛光垫基本上从通道中去除所有残留的材料。为了实现这一点，抛光垫在约4psi的抛光压力下具有至少5％的压缩率。

摘要： A method of manufacture of magnetic heads which include CoFe elements using CMP is presented. The method includes providing a slurry of Al2O3, adjusting the concentration of H2O2 in said slurry to within a range of 6-12% by volume and balancing mechanical polishing action. The balancing is done by adjusting the table speed of a mechanical polisher to within a range of 55-90 rpm, and adjusting polishing pressure to within a range of 5-7 psi. Also a magnetic head having elements made of CoFe material made by this method is disclosed.

摘要： Unique digital signatures of sensitive or restricted image files are calculated and stored in a database. A hook routine hooks an open or read command when an application opens an image file in order to check for a restricted digital signature of that image file. If present, a digital watermark is added to the image before the application edits that image. A user may then modify the image. A hook routine also hooks a close or write command in order to check for a digital watermark. If present, the digital watermark is removed and a new digital signature for the revised image is calculated. The digital signature for the revised image is then uploaded to a database associated with a DLP server software product, and then pushed periodically down to endpoint DLP client products.

摘要： A utility lighter includes a handle casing, a gas releasing valve, a bendable extension arm, a torch nozzle, a piezoelectric unit and an actuation device. The bendable extension arm has an upper end and a lower end extended from the handle casing, wherein the extension arm has a deformable receiving channel which is extended from the lower end to the upper end and is adapted to be curved when the extension arm is selectively bent between the upper end and the lower end. The torch nozzle is provided at the upper end of the extension arm to communicate with the gas releasing valve through the receiving channel for releasing the gas through the torch nozzle when the actuation device is actuated to depress the piezoelectric unit. The result is that a torch flame is generated at the torch nozzle at a distance from the handle casing.

摘要： A method for work hardening gold contact pads is disclosed. The method includes providing gold contact pads, providing lapping pads, and placing the lapping pads in contact with the gold contact pads to create a contact interface. A liquid medium is then applied to the contact interface while moving the lapping pads relative to the gold contact pads. The liquid medium is preferably a particulate-free pH neutral liquid, which makes water a good choice. Also disclosed is a gold pad having a work hardened surface.
