Abstract: A structural tie shear connector (20) utilized in a concrete and insulation sandwich wall panel (10) having first and second wythes (12, 14) and an insulation layer (16) interposed therebetween. The connector (20) includes first and second horizontal strands (22, 24) of thermally non-conductive material which are adapted to be encased by the respective wythes (12, 14). A transverse web (26) of thermally non-conductive material interconnects the first and second strands (22, 24) through the insulation layer (16). The web (26) includes strands formed into a lattice structure. At least one (30) of the strands (22, 24, 28, 30, 32) of the lattice extends at an angle with respect to one of the first and second strands (22, 24) so as to be in tension when a load is applied to the wall panel (10). The connector (20) resembles a bow tie. The method of making sandwich wall panels (10) disclosed herein includes pouring the first layer (14) of concrete into a form (50); laying a plurality of insulation strips (16A, 16B, 16C, etc.) adjacent each other to define at least one gap (52) therebetween; providing a bow tie shear connector (20) having a chairing loop portion (32) thereon;  while the first layer (14) of concrete is still plastic, inserting the connector (20) through the gap (52) and into the first layer (14) of concrete such that the chairing loop portion (32) rests on the bottom of the form (50); and pouring a second layer (12) of wet concrete onto the insulation strips (16A, 16B, 16C, etc.) in the form (50). The chairing loop (32) positively locates the connector (20) with respect to the form (50), the concrete layers (12, 14) and the insulation layer (16) without being affixed to the insulation.

Abstract: An optical fiber preform having a substrate tube, a cladding layer and a core layer further includes a first barrier layer deposited by a material having a low OH diffusion coefficient between the substrate tube and the cladding layer, wherein the first barrier layer is for substantially preventing OH contained in the substrate tube from being diffused into the cladding layer. The optical fiber preform further includes a second barrier layer formed by depositing a material having a tow OH diffusion coefficient between the cladding layer and core layer, for substantially preventing OH which has been diffused into the cladding layer from the substrate tube from being diffused further into the core layer. Outer and inner OH barriers containing no P2O5 are deposited between the substrate tube and the cladding layer and between the cladding layer and the core layer in a deposition process, such that OH can be effectively prevented from being diffused from the substrate tube to the core layer in a core deposition process, a collapsing process or a closing process.

Patent CA-2408534-C (CA)
Inventor: MIYANO KENJIRO
IPC: G02B6/26
Filed: 2000-12-12
Granted: 2007-04-10
Abstract: The present invention provides an optical waveguide coupler which relaxes the phase matching condition and facilitates the coupling between an optical waveguide and a resonator.      The light in a multimode optical waveguide (1) is coupled directly to a microsphere resonator (2) via evanescent light. Since the size of the microsphere resonator (2) is very small, the efficiency of coupling between the microsphere resonator (2) and the multimode optical waveguide (1) is low. Therefore, under the nonresonance condition, the influence of the microsphere resonator (2) is small, and light propagation through the multimode optical waveguide (1) is not influenced. However, since the intensity of the light stored in the microsphere resonator (2) is high under the resonance condition, even if the coupling efficiency is low, the microsphere resonator (2) outputs light which has approximately the same power as that of the light in the multimode optical waveguide (1).      Therefore, strong coupling condition is always satisfied, and the optical waveguide coupler functions as a filter due to the interference between the light in the multimode optical waveguide (1) and the light that has passed through the microsphere resonator (2).
