摘要:
The present invention relates to a process for preparing an optical waveguide component from acrylate/titanium alkoxide composite material, which is characterized by using an acid-free sol-gel process to prepare a precursor solution of acrylate/titanium alkoxide composite film, then coating the precursor solution on a silicon wafer then drying, and producing the optical waveguide component having channels by using a lithography process. The present invention also relates to an optical waveguide component of acrylate/titanium alkoxide composite material, the material has excellent transparency and its refractive index varies with the amount of titanium alkoxide contained therein. When an optical waveguide component is prepared from the composite the reduction of near-infrared ray is less than 0.7 dB/cm and therefore the waveguide component is advantageous for use as an optical communication element.

An article box for a beach buggy is positioned under the rear end of the saddle of a beach buggy. The frame body of the beach buggy is partitioned and formed with an uncovered accommodating space, and the article box with its opening facing upward is embedded in the accommodating space and concealed under the saddle of the beach buggy. By so designing, after the saddle of the beach buggy is pulled open, the driver can put his safety helmet or other things into the article box, convenient in use.
