Abstract:
An illumination system including a beam splitter, a first lamp, a second lamp, a first reflector, a second reflector, and a light uniforming element is provided. The first and the second lamp emit a first beam and a second beam to the beam splitter, respectively. A part of the first beam reflected by the beam splitter and a part of the second beam passing through the beam splitter constitute a third beam, and the other part of the first beam passing through the beam splitter and the other part of the second beam reflected by the beam splitter constitute a fourth beam. The first reflector and the second reflector reflect the third beam and the fourth beam, respectively. The light uniforming element is disposed on transmission paths of the reflected third beam and the reflected fourth beam.
Abstract:
A layout structure of ball grid array is provided. The layout structure includes: a substrate having a margin area; a plurality of solder ball pads laid on the substrate; a plurality of interconnection vias each electrically coupled to a corresponding one of the plurality of solder ball pads; and at least one of the plurality of interconnection vias arrayed on the margin area so that no interconnection vias are arrayed between one of the plurality of interconnection vias and an edge of the margin area.
Abstract:
A pad is adapted for selectively receiving a first surface mounted component (SMC) and a second SMC on a printed circuit board. The first SMC and the second SMC include a number of footprints respectively. The pad includes a first portion for receiving the first SMC, a second portion for receiving the second SMC. Configurations and sizes of the first portion and the second portion are same with the ones of the footprints of the first SMC and the second SMC respectively. The second portion is overlapped with the first portion. The pad can selectively receive one of the first SMC and the second SMC.
Abstract:
A soft thin laminated substrate including a plastic substrate, an alloy copper layer overlaid on the plastic substrate and a copper foil overlaid on the alloy copper layer. The alloy copper layer is an alloy of copper metal and at least one of nickel, chromium, manganese, molybdenum, iron and phosphorus. The alloy copper layer serves as a tie-coating of the copper foil, whereby the copper foil can tightly attach to the alloy copper layer to associate with the plastic substrate and form the soft thin laminated substrate.

Substituted 2-phenyl-4-quinolone-3-carboxylic acid derivatives and their salts were synthesized. The results of preliminary screening revealed that these compounds are potent in killing solid tumor cancers.
Abstract:
The present invention relates to a handover method of a mobile IPv6 communication network capable of reducing the handover interrupt time, the packet loss rate, and the load of the home agent. The mobile station is a single or a multimode physical access terminal, and monitors a link situation to obtain a network handover initiation. After obtaining initiation information, the mobile station sends handover information including link information of a new access router to a current access router and the current access router returns network information of the new access router, and the mobile station starts a network layer handover of the mobile IPv6 before the link layer handover. Data sent from the communication end to the mobile station is directly sent to a new care-of address of the mobile station. In order to reduce the packet loss, the new access router stores data sent to the mobile station before the mobile station and the new access router establish their connection. After the connection between the mobile station and the new access router is established, data stored in the router is transmitted to the mobile station. In order to reduce the load of the home agent, the home agent only manages the position of the mobile station and is not in charge of packet's encapsulation and forward. The establishment of the connection between the communication end and the mobile station is completed by querying the position of the mobile station from the home agent.
Abstract:
The invention publishes a kind of drug complex with cholagogue and lithontriptic effect and its preparation method; the invention also publishes a kind of quality-control method of a kind of drug complex soft capsule. The invention drug complex is composed by the main materials of mint oil and herit oil. The aforementioned drug is mixed uniformly according to certain proportion, and can be added into conventional accessories to prepare into clinically accepted forms of drug, such as pill, tablet, orally-taken liquid preparation, capsule, granule et al. To control the drug quality according to the quality-control method of the soft-capsule-form drug publicized in the invention, good product stability and high repeatability can be acquired; The invention drug complex has distinct cholagogue, lithontriptic, anti-inflammation, analgesic effect through the pharmacological experiment.

Abstract:
A method for fabricating a mixed-mode device. A first gate oxide layer and a second gate oxide layer are formed. The polysilicon layer is used as a mask to pattern the gate oxide layers. Additionally, a top electrode is formed during the first gate oxide layer is patterned. A bottom electrode is formed during the second gate oxide layer is patterned. The first gate oxide layer and the second gate oxide layer are formed by a single oxidation operation, thus thicknesses of the first gate oxide layer and the second oxide layer can be effectively controlled.
Abstract:
A cord-winding device for a blind assembly having no pull cord includes a base seat defining a slide channel and having a bottom side configured to removably mount the blind, assembly thereto, and an adjustment unit including a slide seat mounted slidably in the slide channel, a plurality of rollers mounted on the base seat and the slide seat, respectively, and a constant force spring having first and second ends respectively fixed to the base seat and the slide seat. A lift cord winds around the rollers and extends through the base seat. The lift cord is configured to extend through the blind assembly after extending through the base seat so as to fee positioned to the base seat and the blind assembly.
