Title: Computer-aided method to partition of on electronic circuit
Inventor: UTZ WEVER
IPC: G06F17/50
Filed: 1997-11-07
Granted: 2001-04-21
Abstract: A partition of an electronic circuit is constructed, in which the electronic circuit is mapped on a graph (102) and weighted-values are assigned to the edges of the graph (103). The weighted-values describe the necessary computing expense to evaluate the electrical describing-values for each element, which is represented by said edge, of the electronic circuit. It will be verified in the iterative method: outwards from previous iterative steps together grouped edges, a sum of said weighted-values of the edges may be resulted through addition of another edge, whether said sum-value locates between a lst threshold-value and a 2nd threshold-value. If this is the case, then it will be also verified whether the number of connections of the elements within the partition with elements outside the partition will be enlarged through the addition of some new edges. If this is not the case, then this edge is accepted in the partition.

Granted: 2001-01-11
Abstract: A description is provided of a cooler (1) for cooling particulate material which has been heat-treated in an industrial kiln such as a rotary kiln (3) for manufacturing cement clinker, which cooler comprises an inlet end (4), an outlet end (5), end walls (6, 7), side walls (8), a bottom (9) and a ceiling (10), at least one supporting surface (11) for supporting the material to be cooled, means (11a, 12) for injecting cooling gas into the material, and means (14) for conveying the material forward across the supporting surface from the inlet end to the outlet end where an inlet section is fitted in the inlet end for receiving the material from the kiln and for distributing this material on the supporting surface. The cooler is peculiar in that it comprises in the inlet section means (20) for distributing the material which is received from the kiln crosswise the cooler in direction towards the side walls of the cooler. It is hereby obtained that it will be possible to extend the width of the cooler without having to extend the inlet section correspondingly due to the fact that the material can be distributed in a better and more uniform manner also in the width direction of the cooler. Besides the wear rate of the moving parts is reduced because the velocity of the conveying means can be reduced and, furthermore, a better heat exchange between the clinker and the cooling gas in the inlet zone is achieved because the thickness of the protective layer of the stationary clinker on the inlet surface can be better adapted.

Title: Coordinating different types of messages sent to mobile radios in a mobile communications system
Inventor: MULLER WALTER
IPC: H04W52/02
Filed: 2000-03-03
Granted: 2002-07-01
Abstract: The present invention coordinates paging, network restriction, and other network-based communications (e.g., mobile measurement requests for 0&M) in a mobile telecommunications network. Paging messages, network messages, and other messages may be consolidated in one message so that the mobile need only power up once to retrieve the various information provided in the one message. In one example, non-limiting embodiment, paging groups of mobile stations and network access restriction groups of mobile stations are merged into a single set of paging and network access restriction groups to which different mobile stations belong. A mobile station therefore need only process one message in order to be informed about paging and network access restriction information pertinent to that mobile station. In the example mobile groups embodiment, that one message corresponds to its consolidated paging and network access group, and the single paging and network access group message is transmitted during a specified time interval associated with the group. As a result, an idle mobile station belonging to that group need only leave a power savings sleep mode to receive that message during the specified group time interval. Otherwise, the idle mobile station can return to the power savings sleep mode to conserve its battery life.

Abstract: The present invention is a high frequency semiconductor soldering method which employs the high frequency heating theory to conduct the soldering process in semiconductor packaging that is different from the conventional soldering process using the soldering furnace. Because the high frequency heating is fast that it can heat a local area up to six or seven hundred degree C in a very short time period, it can be applied in the manufacturing process for those packaging material with less durability under high temperature operation.

Title: ""C"" block roll bending
Inventor: DITTMAR ROBERT WILLIAM
IPC: B21B31/20
Filed: 2000-05-08
Granted: 2002-01-21
Abstract: A work roll bending system for profile control of continuous metal strip during rolling which is especially useful for retrofitting an existing rolling mill absent such feature to provide it with roll bending capabilities. The advantage of the system is its compactness in the vertical direction which facilitates its positioning between housing posts of the rolling mill where space in the vertical direction is often limited. Bending wings for exerting bending forces to work roll chocks with use of hydraulic cylinder and piston assemblies extend from the chocks in an intermeshing manner to allow wings from top and bottom work roll chocks to occupy the same horizontal plane without interference during at least some roll gap settings. That bending wing arrangement also allows for elimination of a ""layer"" of hydraulic cylinder and piston assemblies which also reduces space requirements in the vertical direction.
