    • A process for producing a powdered carboxyl-containing polymer comprising mixing a solution of a water-insoluble polymer containing a carboxyl group per molecule in a hydrophilic organic solvent (e.g., ethanol) and an aqueous solution of a dispersant comprising a neutralized copolymer of a carboxyl-containing unsaturated monomer and a (meth)acrylic ester to precipitate the water-insoluble polymer. Fine polymer particles free from adhesion or agglomeration are obtained efficiently. Since any residual unreacted carboxyl-containing monomers are dissolved out in water as a precipitating solvent, the resulting powdered polymer has a reduced residual content of the unreacted monomers which may be poisonous and is therefore useful as a base resin of cosmetics or a coating resin for applications involving contact with the skin.
    • 一种制备含羧基聚合物聚合物的方法,包括将每分子含有羧基的水不溶性聚合物的溶液在亲水性有机溶剂(例如乙醇)中和包含羧基中和的共聚物的分散剂水溶液 的不饱和单体和(甲基)丙烯酸酯以沉淀水不溶性聚合物。 有效地获得没有粘附或聚集的细聚合物颗粒。 由于任何残留的未反应的含羧基的单体作为沉淀溶剂溶解在水中,因此所得的粉末状聚合物具有降低的可能是有毒的未反应单体的残留量,因此可用作化妆品的基础树脂或用于 涉及与皮肤接触的应用。

    • The present invention enables connection between a wireless sensor node and a service server while reducing load on the wireless sensor node.The wireless sensor node transmits a router solicitation message to a gateway apparatus; the gateway apparatus analyzes the message to extract the discrete information of a device or service, searches for a service server based on such information and acquires the configuration information necessary for execution of a service application of the wireless sensor node; the gateway apparatus multicasts the received router solicitation message into a link; a router within the link receives the router solicitation message, and multicast a router advertisement message which contains the prefix information of an address, etc. into a link; the gateway apparatus sets the acquired configuration information in the router advertisement message and transfers the resultant message to the wireless sensor node; and the wireless sensor node analyzes the message.

    • In a continuous casting process for steel, a molten core inside a strand is stalled at a specific point Q in a pass line of the strand to form a cored portion including no molten steel in the strand downstream of the specific point Q, and the cored portion is rolled by a pair of rolls under pressing into a solid strand in the latter half of a strand drawing stroke. The resulting solid strand comprises a skin formed of a chill crystal and the interior formed of a columnar crystal by addition of proper casting temperature. A through continuous casting/rolling process in which the above improved continuous casting process is combined with a subsequent hot rolling process is also disclosed. A drastic increase in the casting efficiency, an improvement in quality, and an equipment capable of freely adjusting a casting thickness can be resulted so that direct coupling between continuous casting and rolling is achieved and near-net-shaping of various steel materials is promoted.
