摘要： Provided hereinbelow is a process of extrusion-coating the central core, said core being used in a submarine coaxial cable, with an insulator of high pressure-processed polyethylene having a density of from 0.925 to 0.940 g/cm.sup.3 and a melt index of from 0.01 to 0.3 g/10 min with advantages in that said coaxial cable is allowed to be placed on a sea bottom of not less than 500 meters in depth and to effectively transmit alternating current signals with a maximum frequency of not less than 30 MHZ, while attenuation of said signals is reduced, and thus, said coaxial cable has a transmission capacity of not less than 3000 circuits or channels with a frequency band of from 3 to 6 KHz per each circuit or channels, wherein the insulator-covered-core is continuously extruded from an extruder and then is gradually cooled in cooling water troughs to room temperature so that the water content of said insulator, without formation of voids between said central core and said insulator, is reduced by as much as possible.
摘要翻译：在下文中提供了一种挤压涂覆中心芯的方法，所述芯用在海底同轴电缆中，其中具有密度为0.925-0.940g / cm 3和熔体指数为0.01的高压加工聚乙烯绝缘体至0.3g / 10min，其特征在于允许将所述同轴电缆放置在深度不小于500米的海底上，并有效地传输最大频率不小于30MHz的交流信号，同时衰减的所述信号被减少，因此，所述同轴电缆具有每个电路或通道具有不小于3000个电路或具有3至6KHz频带的通道的传输容量，其中绝缘体覆盖芯被连续挤出然后在冷却水槽中逐渐冷却至室温，使得所述绝缘体的水含量在所述中心芯和所述绝缘体之间不形成空隙，由此减少越多越好。

摘要： A laminated film has layer(s) A and layer(s) B.sub.1, obtained by laminating at least one layer A and at least one layer B.sub.1. The layer A comprises a resin composition comprising (a) 20-100% by weight of an amorphous polyolefin containing at least one component, in an amount of at least 50% by weight in said amorphous polyolefin, selected from the group consisting of propylene and butene-1 and (b) 80-0% by weight of a crystalline polypropylene, (B) the layer B.sub.l comprises a crystalline polypropylene. At least one of the two outermost layer is the layer B.sub.1. The laminated films can be used in various applications by themselves, but may be laminated with a polyester film, a nylon film, a stretched polypropylene film or the like to improve the mechanical strengths, gas-barrier property, printability, etc.

摘要： A heat-shrinkable cover sheet used for covering and protecting the peripheral surface of a joint of, for example, a steel pipe or cable is provided. The heat-shrinkable cover sheet has two branched tongue-like portions on each of both the ends in the direction of thermal shrinkage. A heating element formed of a heating electric conductor wire is included and built in the body portion of the cover sheet, the front tongue-like portion on one end of the cover sheet and the back tongue-like portion on the other end of the cover sheet, in a manner such that thermal shrinkage of the entire sheet is not prevented. The heating element included in at least one of the tongue-like portions having the heating element included and built therein is independent from the heating element of the body portion of the sheet, so that application of electricity to the independent heating element and stopping of application of electricity to the independent heating element can freely be carried out while electricity is applied to the heating element of the body portion.
