Title: Dichroic polarizing film, optical polarizer device, and method of making the same
Inventor: WILLIAMS BRIAN HOWARD
IPC: G02B5/30
Filed: 1999-07-20
Granted: 2005-11-11
Abstract: A dichroic polarizing film is made, for example, by, first, dissolving polyvinyl alcohol and a second polymer, such as, polyvinyl pyrrolidone or a sulfonated polyester, in a solvent. The ratio of polyvinyl alcohol to second polymer is between about 5:1 to 100:1 by weight. The film is coated on a substrate, dried, and then stretched to orient at least a portion of the film. The film incorporates a dichroic dye material, such as iodine, to form a dichroic polarizer. This polarizer may be used in conjunction with a multilayer optical film, such as a reflective polarizer, to form an optical polarizer. The multilayer optical film may contain two or more sets of polyester films, where at least one of the sets is birefringent and orientable by stretching. The polyvinyl alcohol/second polymer film and the multilayer optical film may be simultaneously stretched to orient both polymer films.

Title: Manufacturing method of terminal insulating sleeve
Inventor: LIOU CHING-JIE
IPC: H01R4/70
Filed: 1999-09-17
Granted: 2001-09-21
Abstract: The present invention relates to a kind of manufacturing method for terminal insulating sleeve, in which the insulating sleeve of connection wire terminal can be manufactured by low cost equipment and method such that the processing cost is lowered. In addition, the present invention has the effects of easily inserting and gathering the electric wire to clamp copper wires. The present invention mainly forms a straight tube by pulling a tube and cutting it off instead of using the ejection molding. One end of the straight tube is reamed so as to form a large aperture portion and a small aperture portion. The joining position between large aperture portion and small aperture portion is compressed to form a contracting neck portion that has a slant flange at the inner surface. The present invention adopts the manner of pulling a tube and compressing molding such that it is capable of manufacturing through the use of inexpensive equipment without using the plastic ejection machine and expensive molds for ejection molding. Additionally, a contracting neck portion, which cannot be reached by ejection molding, can be obtained by this invention. Furthermore, due to the formation of contracting neck portion, the problem of blocking copper wires caused by the thickness of terminal clamping sleeve can be palliated such that copper wires are easily gathered up and suitably inserted into the clamping sleeve to further enhance the completely clamped effects.

Title: Processing chamber with rapid wafer exchange
Inventor: WHITE ANTHONY
IPC: H01L21/26
Filed: 1999-11-09
Granted: 2001-05-01
Abstract: An apparatus for processing substrates includes a chamber, a substrate transfer element for transferring a substrate to and from the chamber, and a substrate support for receiving and holding a substrate within the chamber. The apparatus also includes multiple pins positioned and configured to be received by respective holes in the chamber bottom and moveable between a retracted position and an extended position. A pin actuation system is provided for moving the pins between the retracted position and the extended position. The pin actuation system controls the velocity at which the pins move and varies the speed of the pins by accelerating or decelerating at particular points during the pin cycle. A reduction in the cycle time is facilitated by accelerating the lift pins to relatively high speeds and then slowing the pins down prior to their arrival at locations where the substrate or wafer may be damaged. The throughput of the chamber can be increased, the likelihood of damage to the substrate can be reduced, and bouncing of the substrate while supported by the pins can be reduced.

Title: System and method for providing an accurate estimation of received signal interference for use in wireless communications systems
Inventor: SINDHUSHAYANA NAGABHUSHANA T
IPC: H04B1/7113
Filed: 2000-05-10
Granted: 2001-11-01
Abstract: A system for providing an accurate interference value signal received over a channel and transmitted by an external transceiver. The system includes a first receiver section for receiving the signal, which has a desired signal component and an interference component. A signal extracting circuit extracts an estimate of the desired signal component from the received signal. A noise estimation circuit provides the accurate interference value based on the estimate of the desired signal component and the received signal. A look-up table transforms the accurate noise and/or interference value to a normalization factor. A carrier signal-to interference ratio circuit employs the normalization factor and the received signal to compute an accurate carrier signal-to-interference ratio estimate. Path-combining circuitry generates optimal path-combining weights based on the received signal and the normalization factor. In the illustrative embodiment, the system further includes a circuit for employing the accurate interference value to compute a carrier signal-to-interference ratio. An optimal path-combining circuit computes optimal path-combining weights for multiple signal paths comprising the signal using the accurate interference value and provides optimally combined signal paths in response thereto. A log-likelihood ratio circuit computes a log-likelihood value based on the carrier signal-to interference ratio and the optimally combined signal paths. A decoder decodes the received signal using the log-likelihood value. An additional circuit generates a rate and/or power control message and transmits the rate and/or power control message to the external transceiver.

Title: A linear guide way
Inventor: WU CHING-SHAN
IPC: F16C29/06
Filed: 2000-05-24
Granted: 2001-04-11
Abstract: Conventional linear guide ways are difficult to manufacture when the dimension is smaller, and have the problems of peeling-off between metal and plastic and temper deformation of material, if manufactured by plastic injection molding method. For the linear guide way of this invention, a spring leaf is used to join the guide block body and an end cap. Because the elastic force of the spring leaf relates to the deformation amount and the slight change in deformation amount does not result in dramatic change in elastic force, a elastic force between the end cap and the guide block body can continuously be maintained while the guide block of the linear guide way of this invention is put to use, so as to prevent gaps to be formed between the guide block body and the end cap, and to eliminate the problem of peeling-off of plastic material. Further, the assembly of using spring leaf to join is easy and manufacturing cost is low.

Title: Nickel alloy films for reduced intermetallic formation in solder
Inventor: CHALCO PEDRO ARMENGO
IPC: H05K3/24
Filed: 2000-06-29
Granted: 2001-10-21
Abstract: A method is provided for forming a solder joint to a pad, in which the thickness of the intermetallic layer formed by nickel in contact with solder is significantly reduced. A first layer of nickel is provided on the pad; a second layer of a noble metal (preferably gold) is then provided overlying the first layer. The first layer and the second layer are then annealed, thereby forming an alloy layer including nickel and the noble metal between the first layer and the second layer. Contacting the second layer with a molten solder (where the solder includes tin) then causes the noble metal to dissolve in the solder and the solder to subsequently wet the alloy layer, forming an intermetallic layer including nickel, the noble metal and tin. Only a thin intermetallic film grows, thus improving the reliability of the solder joint.
