摘要： A new micro-porous membrane having a layer of minimum pores inside is disclosed. This membrane can be produced by a kind of dry-wet method in which a gas is in contact with the surface of the spread solution before it is immersed in a solidifying bath to form a coacervation phase only in the surface layer of the spread solution. It is quite important to control the amount of non-solvent for a utilized polymer contained in the gas as well as a blowing rate of the gas toward the above mentioned surface. The micro-porous membrane of the present invention not only has an improved filtration flow rate and life as a filter, but also the risk of being damaged by scratches is minimized.
摘要翻译：公开了一种具有内部最小孔层的新微孔膜。该膜可以通过一种干式湿法制造，其中气体在浸入固化浴中之前与扩散溶液的表面接触以在扩散溶液的表面层中形成凝聚相。控制气体中所使用的聚合物的非溶剂量以及朝向上述表面的气体的吹送速度是非常重要的。本发明的微孔膜不仅具有改善的过滤流速和作为过滤器的寿命，而且由刮痕损坏的风险也被最小化。

摘要： A photographic film, particularly a 35-mm film, which can tear only in a direction opposite from the picture regions of the film. Cuts, such as a V-shaped notch or a linear cut, are formed in the film extending from each perforation in a direction opposite to the picture region of the film. If a high force is applied to the perforations of the film while the film is being conveyed, the film will tear only at the notch thus absorbing the force and preventing damage to the film conveying mechanism.
摘要翻译：照相胶片，特别是35mm胶片，其仅能够在与胶片的图像区域相反的方向上撕裂。在从每个穿孔延伸的膜中，沿着与膜的图像区域相反的方向形成诸如V形凹口或线形切口的切口。如果在输送膜时对膜的穿孔施加大的力，则膜将仅在凹口处撕裂，从而吸收力并且防止膜输送机构的损坏。
