IPC: C08F8/12
Filed: 2000-09-28
Abstract: The present invention is a method of making acrylonitrile copolymers having multi block structure comprising acrylic acid, acryl amids and acrylamidine hydrophilic groups in hydrophilic blocks and residual nitrile groups in hydrophobic blocks, by partial hydrolysis of polyacrylonitrile to a predetermined hydrolysis conversion at which the hydrolysis is self terminating, by a process that improves quality and reduces product heterogeneity. It includes forming a first reaction mixture which includes polyacrylonitrile dissolved in an aqueous reactive solvent containing sodium thiocyanate; forming a second reaction mixture comprising a reaction catalyst of the general formula MY dissolved in an aqueous reactive solvent containing sodium thiocyanate; mixing the reaction mixtures of steps (a) and (b) above to form a master reaction mix; dividing the reaction mix into a plurality of physical reaction compartments so as to increase outer surface area relative to volume as compared to outer surface area of a single reaction compartment to enhance cooling efficiency and to reduce undesirable center core thermal effects; and, heating the divided master reaction mix to a predetermined reaction temperature range and maintaining the temperature range for a predetermined time sufficient for completion of a predetermined level of hydrolysis at which the resulting copolymer solution is substantially stable at ambient temperature. The invention also includes hydrogel products resulting from the method.

Abstract: The present invention relates to the requirement of security in an ad hoc network. More particularly it relates to the problem within ad hoc networks, not having on-line connections to a particular server for getting desired public keys or certificates, required to create trust relations. Within an ad hoc communication network, some of the nodes have a mutual trust relation to each other, thus constituting a trust group. An additional node within the network is being a candidate node for joining the trust group. An X-node is identified, being a member of a trust group and having a trust relation with the candidate node. The X-node distributes trust relations between the members of the trust group and the candidate node. <IMAGE>

Title: プラズマ表示パネル
IPC: H01J11/12
Filed: 2000-10-27
Abstract: (57)【要約】
放電電圧を低め、プラズマの体積を大きくして放電効率を向上させたプラズマ表示パネルである。プラズマ表示パネルは、上部基板の各画素の第１、第２の電極に電気的に接続され、第２の基板に向かって伸びた、金属材料からなる不透明なフェンスタイプ電極を含む。その結果、個々の画素の放電の間、発生されるプラズマの損失が最小化され、放電電圧が低められる。また、電極面積が大きくなり、プラズマの発生空間が増大し、プラズマのエネルギー損失が減少することにより、安定的な放電が行われる。更に、隔壁により、単位画素が個別化されることによって、隣接する画素の相互作用が防止され、画素のサイズを小さくして高画質の画面を得ることができる。
