Title: Improved tinning process
Inventor: JANG SHENG-CHIAN
IPC: C25D3/30
Filed: 2003-01-07
Granted: 2005-01-11
Abstract: An improved tinning process comprises adding a pre-plating step prior to the tinning process in order to deposit a uniform thin tin layer on a to-be-plated surface at a milder rate, prior to entering the main tank for tinning. Since the deposition rate of the pre-plating is slower, the tin grains deposited on the surface are smaller and the stacking of the thin tin layer is denser and smoother. Thus, the pre-plated surface during the tinning process not only can obtain a uniform tin surface but also can reduce the amount of use of organic additives such as a tinning surfactant or a surface smoothening agent, etc. or even eliminate such a use.

Title: Method for producing organic electroluminescence element and the organic electroluminescence element made thereby
Inventor: MASUICHI MIKIO
IPC: H05B33/22
Filed: 2003-04-23
Granted: 2004-12-01
Abstract: Provided are a method for producing an organic electroluminescence (EL) element and a product made thereby. By this method, the mixing of organic EL materials applied onto the partitioned spaces formed on a substrate can be prevented. After a hole conveying material 8 has been selectively supplied to each element space SP, a hole conveying layer is formed by drying the material with heat-treatment applied to substrate 2 thereby the material 8 may be prevented from staying on the top of partition. Further, a liquid-expellent treatment is applied to the tops of partitions. More particularly, a layer 12 containing fluorine is formed on the tops of partitions as liquid-repellent. After such treatment, the organic EL material 14R is supplied to the partitioned space. At this time, the movement of the material to the neighbor space will be stopped by the layer 12, therefore the mixing of organic EL material having plural colors can be prevented effectively.

Title: Head/data request in 3D graphics
Inventor: HUANG HIS-LIN
IPC: G06T1/20
Filed: 2003-11-18
Granted: 2005-01-11
Abstract: A method for efficiently processing graphics data for graphics primitives, the graphics data including vertex coordinate information and vertex attribute data. Coordinate information, in the form of homogeneous coordinates, of the graphics primitive determines whether the graphics primitive is to be rendered. If the primitive is to be rendered, then attribute data associated with the location information is retrieved. However, if the data is not to be rendered, then the location information is discarded. By only retrieving parameters for a primitive that is rendered, performance is increased. In one embodiment, the attribute data is fetched before it is known whether or not the graphics primitive is to be rendered, and if not, the prefetch is aborted, and new location information is fetched.

Title: Method and apparatus for local and distributed data memory access (""DMA"") control
Inventor: SPENCER THOMAS VINCENT
IPC: G06F/
Filed: 2004-05-19
Granted: 2006-07-01
Abstract: An apparatus for local direct memory access control includes a processor unit for generating a direct memory access designator when needed data is not available and continuing processing which does not require the unavailable data. A memory access designator holder receives the memory access designator, and a local data memory access controller performs a data memory access transaction in accordance with the content of a descriptor. Staging registers hold components of a data memory access designator and transfer the components to a selected portion of the data memory access designator holder. The data memory access controller transfers the contents of the staging registers to the data memory access designator holder when one of the staging registers is written to by the processor unit. The processor unit stalls if a write to the staging register occurs when the data memory access designator holders contain a data memory access designator, and ceases the stall when one of the plurality of data memory access designator holders ceases to contain a data memory access designator.
