Patent CA-2404743-A1 (CA)
Inventor: NETTI MARIA CATERINA
IPC: G02F1/31
Filed: 2001-04-06
Abstract: In order to create an optical device with a photonic band gap extending in two dimensions and with very uniform properties in any direction and for any polarisation state, to within 1 %, air holes are etched within a substrate of low refractive index material such silicon oxynitride or silica glass. The ratio of air hole area to the remainder of the substrate is low, being less than 35 %. The air holes define a quasicrystal structure, having twelve fold symmetry, being based on a square-triangle system. In another development, an etched substrate with a regular crystal structure or quasicrystal structure exhibits a non-linear refractive index. Two adjacent areas in such a substrate have different lattice properties, or have defects in the lattices, to create a unidirectional transmission path (diode action). A further beam of light may be used to modulate the transmission path by reason of the non-linear refractive index.

Title: Method for producing a piece of timber including heartwood
Inventor: LEE SHEN-BA
IPC: B27M1/02
Filed: 2003-01-07
Abstract: A method for making wood with heartwood has steps of forming a wood log with a heartwood (22) from a tree, pressure treatment to the wood log with the heartwood (22), drying the wood log and forming the wood log to a desired shape. The pressure treatment process is to apply a desired pressure to the wood log to reduce a moisture content of the wood log with the heartwood (22) to an even level.  This can avoid the wood log with the heartwood (22) to split, crack or deform during the drying process. The utilization of a tree can be increased, and the process for gain a wood material is simplified.
