摘要： Actuation and control of the deployment of a polymeric memory-shape material on a wellbore device on a downhole tool may be accomplished by treating a compacted or compressed polymeric memory-shape material with a deployment fluid to lower its Tg and/or decrease its rigidity, thereby softening the polymeric shape-memory material at a given temperature and triggering its expansion or recovery at a lower temperature. Alternatively, the deployment of the compacted or compressed polymeric memory-shape material may be prevented or inhibited by shielding the material with an environment of a fluid that does not substantially lower its Tg, decrease its rigidity or both, and then subsequently contacting the material with a deployment fluid.

摘要： The present invention aims to provide a light-diffusing heat shrinkable tube which has light diffusibility that enables LED point light sources to give an impression of a surface light source such as a conventional fluorescent lamp. The tube is also capable of suppressing scattering of broken fragments of a transparent pipe that includes the light sources, in the case of an unexpected accident including falling of the pipe. The present invention also aims to provide a linear LED light including the light-diffusing heat shrinkable tube. The light-diffusing heat shrinkable tube including a polyester resin and a light diffusing agent, the polyester resin having an inherent viscosity of 0.8 to 1.4 dl/g, the tube comprising 0.1 to 2.5 wt% of the light diffusing agent, the tube having a thickness of 60 to 300 µm.

摘要： [PROBLEMS] Disclosed is a heat shrinkable film having excellent heat resistance, content resistance, impact resistance, low/high temperature cycle resistance, and abrasion resistance. [MEANS FOR SOLVING PROBLEMS] Specifically disclosed is a heat shrinkable film comprising an intermediate layer (1), a front surface layer (2) and a back surface layer (3) so arranged as to sandwich the intermediate layer (1), and an overcoat layer (4) arranged on top of the front surface layer (2). The intermediate layer (1) contains first cyclic olefin resin and a random copolymer of ethylene and another ±-olefin or a random copolymer of propylene and another ±-olefin. The front surface layer (2) and the back surface layer (3) respectively contain second cyclic olefin resin and linear low-density polyethylene resin. Such a multilayer heat shrinkable film is formed into a tubular shape in such a manner that the overcoat layer (4) is on the outside. A secondary battery is fitted into the thus-formed tube of the multilayer heat shrinkable film and the tube is heat shrunk, so that there is obtained a wrapped battery.
