摘要： A dope is produced from TAC and a mixture solvent whose main compound is dichloromethane. The dope is cast from a casting die onto a casting drum. In an upstream side from the casting die, a decompression chamber having air pipes is provided. The difference from the ordinate pressure to the pressure inside the decompression chamber is −2000 Pa to −10 Pa. An air is fed through the air pipes into the decompression chamber. Thus the pressure fluctuation in the decompression chamber is reduced, and the pressure becomes almost constant in the widthwise direction. Therefore, the entrained air and another air are prevented from entering into the decompression chamber, which makes the shape of the bead of the discharged casting dope stable. When having self-supporting properties, the casting film is peeled as a film from the casting drum and dried to be a TAC film without thickness unevenness.
摘要翻译： 由TAC和主要化合物为二氯甲烷的混合溶剂制备涂料。 将涂料从铸模铸造到铸造鼓上。 在铸模的上游侧设有具有空气管的减压室。 减压室内的纵坐标压力与压力的差异为-2000Pa〜-10Pa，空气通过空气管进入减压室。 因此，减压室中的压力波动减小，并且压力在宽度方向上变得几乎恒定。 因此，防止了夹带的空气和另一空气进入减压室，这使得排出的浇注涂料的珠的形状稳定。 当具有自支撑性质时，将流延膜从流延鼓中剥离成膜，并干燥成TAC膜而没有厚度不均匀。

摘要： In the case where multiple slide hopper is used for simultaneous multilayer bead coating of photosensitive material, streak defect is occasionally cause, particularly in the case of coating photothermographic material, especially when the outermost layer includes materials capable of increasing optical density such as toner it more frequently happens. It is found that streak defect is restrained when meniscus curvature of upper side bead becomes less than 7.2 mm−1. This condition can be kept by selecting a proper value of clearance between the web surface and the lip of the slide hopper, that is from 0.10 mm to 0.40 mm, and a proper value of pressure in a lower side of the bead, that is from −100 Pa to −700 Pa.

摘要： A dope is cast onto a casting drum from a casting die while forming a casting bead. Oxygen concentration at the vicinity of the casting bead is set to 0 vol % or more and less than 10 vol %, and a static electricity applying electrode applies static electricity between the casting drum and the casting bead. An intervening film forming device supplies intervening film forming liquid onto the casting drum to form an intervening film. A compression chamber decompresses a downstream area from the casting bead. Thereby, it is possible to form the casting bead having a stable shape, and enhance the extent of adhesion between a casting film and the casting drum. Accordingly, it is possible to enhance the extent of adhesion between the casting drum and the casting bead, prevent occurrence phenomenon of air entrainment, and speed up a film forming speed, thus forming a polymer film.

摘要： An improved anchor agitator is provided for performing uniform and effective stirring of the fluidized bed zone of a polymerization vessel in a gaseous phase polymerization, especially of olefins such as ethylene and propylene. The anchor agitator includes at least two pairs of arms provided on a rotating shaft in mutually crossing positions. A pair of main blades is provided at opposite outward end portions of one pair of arms and at the opposite outward portions of each remaining pair of arms a pair of subsidiary blades is provided. The main blades and subsidiary blades extend substantially parallel along the axis of the rotating shaft and each pair of blades is located substantially equidistant from the axis of the rotating shaft. The pair of main blades is located farther from the axis of the rotating shaft than the subsidiary blades. The main blades and subsidiary blades are uniquely designed to avoid the formation of coherent crusts or lumps near the inner wall of the polymerization vessel and to avoid formation of a vortex formed centrally in the fluidized bed zone of the vessel in the vertical direction of the zone. The unique angular relationships and distance relationships of the main blades and subsidiary blades also avoid the likelihood of vibration due to mechanical imbalance of the agitator while at the same time allowing the agitator to be easily designed and built.
摘要翻译： 提供了一种改进的锚式搅拌器，用于在气相聚合中，特别是烯烃如乙烯和丙烯中均匀有效地搅拌聚合容器的流化床区。 锚式搅拌器包括设置在相互交叉位置的旋转轴上的至少两对臂。 一对主叶片设置在一对臂的相对的外端部，并且在每个剩余的一对臂的相对的外侧部分设置有一对辅助叶片。 主叶片和副叶片沿着旋转轴的轴线基本平行地延伸，并且每对叶片基本上等距离旋转轴的轴线定位。 一对主叶片比辅助叶片远离旋转轴的轴线。 主叶片和辅助叶片是独特设计的，以避免在聚合容器的内壁附近形成连贯的结壳或团块，并且避免在该区域的垂直方向上在容器的流化床区域中心形成的涡流形成 。 主叶片和辅助叶片的独特的角度关系和距离关系也避免了由于搅拌器的机械不平衡而引起的振动的可能性，同时允许搅拌器易于设计和建造。
