Abstract: A concrete load-bearing wall with compound heat-insulating layer includes wall body (1) and connecting beam (2). Two layers of prefabricated heat-insulating concrete wall bodies (11a, 11b) are set in the wall body (1) of external wall, said prefabricated heat-insulating concrete wall body (11a, 11b) is a concrete plate (5) whose external surface is covered with a heat-insulating material layer (4), every layer of the prefabricated heat-insulating concrete wall body is composed of several trough-type or L-shaped prefabricated heat-insulating concrete wall body units (13). A concrete wall body vertical rib (12) is cast in situ between two adjacent prefabricated heat-insulating concrete wall body units (13) in same layer and connects them into integrity. The upper and lower ends of the rib (12) connect together with the beam of the floor, and the external side of the connecting beam (2) is covered with the heat-insulating material layer (4).

Abstract: A composite concrete shear wall for heat insulation comprises a wall (1) and a link beam (2). The wall (1) is composed of a prefabricated concrete wall for heat insulation (11) and a cast-in-place concrete wall. The prefabricated concrete wall (11) is a concrete panel (5), one surface of which is covered with heat insulation layer (4), and steel members (14) are embedded in the prefabricated concrete wall (11). One end of the steel members is embedded in concrete panels, and the other is projected from the heat insulation layer. The steel members are connected and located along the prefabricated concrete wall to form a framework of steel reinforcement. The prefabricated concrete wall (11) and the cast-in-place concrete wall (12) are cast and folded to be an integral.

Abstract: A variable optical attenuator multiplexer having at least one thermal isolating optical joint. The variable optical attenuator multiplexer including a plurality of planar lightwave circuit components, such as, for example a combination of an array waveguide grating, a variable optical attenuator, and/or a power monitor. The planar lightwave circuit components are joined with an optical adhesive. The components may be thermally isolated by the formation of a widened space or gap between the component joints, and/or by creating a trench in the optical adhesive.

Abstract: The coupling properties of an optical device having at least two inputs and two outputs may be more accurately measured by simultaneously measuring the optical transmission through all outputs for light coupled to each input to the device. An optical switch may be used to selectively couple the light to each of the device inputs. This removes the need to remove the light source from one input and to reconnect it to another input. By proper processing of the measured optical transmission corresponding to each input, an accurate and precise value for the transfer function, including polarization properties, of the device may be obtained independent of the insertion losses in the system.
