Title: Method and system for channel allocation in multi-frequency wireless network
Inventor: TSAI HSIEN-MING
IPC: H04W36/04
Filed: 2001-10-02
Granted: 2003-08-01
Abstract: The invention relates to a method and system for channel allocation in multi-frequency wireless network. The system comprises a channel allocation center, a micro-cell base station, a macro-cell base station and a mobile station. When a mobile station attempts to create a connection or proceed a handover, the channel allocation center employs the repackaging on demand method of the invention to allocate wireless channels of micro-cell base station or macro-cell base station for mobile station to operate. The repackaging on demand method consists of the following procedures: first allocating an idle micro-cell channel, if there is no available micro-cell channel, then allocating an idle macro-cell channel; if no available macro-cell channel, then proceeding repackaging. The repackaging transfers the connection of another mobile station from macro-cell to another micro-cell and retakes the occupied macro-cell channel for further allocation to the mobile station. If there is not any connection for repackaging, the mobile station is blocked or terminated in the end. The invention can reduce the call blocking rate and call handover rate of mobile station in multi-band wireless network to improve customer satisfaction of mobile station.

Title: Manufacturing method for semiconductor substrate
Inventor: NAGAI SEIJI
IPC: C30B29/38
Filed: 2002-03-29
Granted: 2004-05-01
Abstract: The subject of the present invention is to use cheaper silicon as the bottom substrate to produce high quality semiconductor crystals with smaller dislocation, no cracks and poly-crystal blocks (high temperature reaction portion). The solution of the present invention is to use the reaction stop layer (crystal material B) to prevent the reaction of Si and the GaN family semiconductor (semiconductor crystal A), such as GaN. The bottom substrate (Si substrate) is formed with a reaction stop layer composed of SiC or AlN with melting point and heat endurance higher than the semiconductor crystal A. Even when the crystal A is in the condition of crystal growth at high temperature and in a long period, it will not form the high temperature reaction portion near the silicon interface. Moreover, the void or film can release the stress applied on the reaction stop layer. Thus, the present invention can form the reaction stop layer without cracks in the longitudinal direction, because it can more firmly break the bottom substrate and the semiconductor crystal A for preventing the occurrence of high temperature reaction portion; furthermore, using the stress releasing effect can also suppress the dislocation density of semiconductor crystal A as low as possible.

Title: CMOS tapered gate and synthesis method
Inventor: CURRAN BRIAN W
IPC: G06F17/50
Filed: 2002-04-18
Granted: 2003-07-11
Abstract: A high-performance gate library is augmented with tapered gates. The widths of the stacked devices are varied to reduce the delay through some of the input pins. For example in a tapered NAND gate the bottom devices in the NFET stack are have longer widths than the top device to achieve smaller top input to output pin delay at the expense of larger bottom input to output pin delay. The method of using synthesis algorithms modifies the input net to gate pin connections and swaps traditional non-tapered gates with tapered gates to improve the delay of the timing critical paths. The latest arriving gate input net is swapped with the net connected to the top pin. The gate is then converted to a tapered gate provided the paths through the bottom gate input(s) that are not timing critical.

Granted: 2006-08-11
Abstract: A pressure vessel having a removable closure head in a high radiation environment is closed by placing the closure head having a flange over and spaced from the flange of a pressure vessel body containing fissile material. The closure studs are installed in closure stud holes of the pressure vessel body flange. Transition nut members of hydraulic nut assemblies are threaded onto the closure studs. Hydraulic hoses are connected between the hydraulic nut assemblies and a pressure source. The pressure source simultaneously pressurizes the hydraulic nut assemblies to simultaneously apply a uniform force to the closure studs sufficient to seat the spaced apart closure head flange on the pressure vessel body flange and to elongate the closure studs. The hydraulic nut assemblies are locked in place over the closure head flange while the force is applied to the closure studs and the closure studs are elongated. The hydraulic pressure on the hydraulic nut assemblies is released while the hydraulic nut assemblies are locked in place over the closure head flange and the closure studs are elongated. The hydraulic nut assemblies may remain connected with the hydraulic hoses after the pressure vessel has been returned to on-line operations and is generating thermal power. The hydraulic hoses connected with the hydraulic nut assemblies may be vented while generating thermal power in the pressure vessel.
