Title: Microfluidic chip
Inventor: GOETZEN REINER
IPC: B01L3/00
Filed: 2004-11-17
Granted: 2010-05-25
Abstract: The invention relates to a microfluidic chip for biological, chemical and medical analysis. Cavities and channels, which connect these cavities to one another and which transport, based on the capillary effect, liquids required for carrying out analysis and synthesis, are arranged inside said microfluidic chip. At least one of the cavities is a reaction chamber. The microfluidic chip is characterized by having a layered construction made of light-curing hydrophilic plastic material based on a 3-D layer model and by having a covering layer made of a hydrophobic material. In the layered body made of hydrophilic material, channels that come from different cavities and do not intersect lead to the at least one reaction chamber.

Title: Method and apparatus for group communication with end-to-end reliability
Inventor: LIU ZHEN
IPC: H04L12/26
Filed: 2005-04-29
Granted: 2010-07-20
Abstract: The present invention addresses scalability and end-to-end reliability in overlay multicast networks. A simple end-system multicast architecture (Fig. 3) that is both scalable in throughput and reliable in an end-to-end way is used. In this architecture, the transfers between nodes use TCP with backpressure mechanisms to provide data packet transfers between intermediate nodes (16) having finite-size forwarding buffers (22). There is also a finite~size backup buffer (24) in each node to store copies of packets which are copied out from the receiver window (20) to the forwarding buffers (22). These backup buffers (24) are used when TCP connections are re-established to supply copies of data packets for the children nodes (18) after their parent node fails, maintaining a complete sequence of data packets to all nodes within the multicast overlay network. The architecture provides end-to-end reliability, tolerates multiple simultaneous node failures and provides positive throughput for any group size and any buffer size.

Abstract: Many herbicidal compositions have been developed and practically used.  However, types of weeds to be controlled are also many, and their emergence extends over a long period. Accordingly, it is desired that a herbicidal composition be developed which has a wider herbicidal spectrum and which is highly active and has a long lasting effect. As a result of a research to solve such problems, the present inventors have found it possible to obtain a highly practical herbicidal composition by a combined use of (A) 2-(4,6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl)-N,N-dimethylnicotinamide or its salt and (B) N2-tert-butyl-6-chloro-N4-ethyl-1,3,5-triazine-2,4-diamine or its salt, and thus have accomplished the present invention.
