摘要： A process for production of a composite porous film wherein a porous support, of which both sides have been coated with a solution (dope) of an organic polymer compound in a water-soluble organic solvent to form a coated film, is passed through an air gap step and conveyed into a coagulating bath comprising water or a mixture of water with the same solvent as the organic solvent, and is then immersed in the coagulating bath so that the coated film on both surfaces of the porous support directly contact the coagulating bath for coagulation, and is then washed and dried. This production process is suitable for production of non-aqueous secondary battery separators, and yields non-aqueous secondary battery separators with good handling properties and at low cost, whereby the ion permeability, adhesion with electrodes and electrolyte solution retention can be strictly controlled.

摘要： A prestressed concrete structure comprising an elongated concrete molded article having a pair of side surfaces opposed to each other, a plurality of tensile members laterally extending through the concrete molded article to be secured at each end to the side surfaces of the concrete molded article in a tensioned state and imparting a compressive load to the concrete molded article, side guards arranged along both side surfaces of the concrete molded article so as to cover the ends of the tensile members, and reinforcing members arranged on the side surfaces of the side guards in order to prevent the broken tensile members from protruding beyond the side surfaces thereof breaking through the side guards when the tensile members in the tensioned state are broken. The reinforcing members stretch little in the longitudinal direction but easily stretch in the transverse direction on the side surfaces of the side guards, and when pushed from the inside by the ends of the tensile members that protrude as a result of breakage, the peeling of the reinforcing members spreads out in the longitudinal direction of the concrete molded article on the side surfaces of the side guards but spreads out little in the transverse direction.

摘要翻译： 一种预应力混凝土结构，包括具有一对相对的一对侧面的细长混凝土模制品，多个横向延伸穿过该混凝土模制品的拉伸构件，以在每个端部固定在混凝土模制品的侧表面上 张紧状态并赋予混凝土模制品压缩载荷，沿着混凝土模塑制品的两个侧表面布置的侧护板，以便覆盖拉伸构件的端部，以及按顺序设置在侧护板的侧表面上的加强构件 为了防止当处于张紧状态的拉伸构件断裂时，断裂的拉伸构件突出超过其侧表面突破侧护板。 加强构件在纵向方向上几乎不伸长，但是在侧护板的侧表面上沿宽度方向容易拉伸，并且当由于断裂而突出的拉伸构件的端部从内侧推动时， 加强构件在侧护板的侧面上在混凝土模制品的纵向方向上展开，但是在横向方向上几乎不扩展。
