A low cost and simple method for preparation of diffusion sheets comprising the steps of swelling, wetting and dispersing nano-scale clay, toluene, and a dispersant to form a paint. The paint is then coated on a surface of a polymer substrate by a wet coating process to form a diffusion layer which includes the nano-scale clay as diffusion particles.

Method for preparation of diffusion sheet

The diffusion beads according to the present invention have a core-shell structure of multi-layered beads consisting of organic and inorganic materials. The diffusion beads are used for improving functions of conventional organic and inorganic polymer diffusion beads. The structure according to the present invention no only enhances light scattering characteristics of the diffusion beads, but also strengthens the thermal stability and geometric stability thereof.

Diffusion beads with core-shell structure

A disposable two-step endoscope for examining human organs includes an image capturing and transmission device and a cable that may be disconnected. The image capturing and transmission device includes a body, luminous devices, an optical image capturing device, a wireless transmission device and an internal power supply. The cable transmits the electric power outside and signals. The luminous device projects light on the human organs. The optical image capturing device captures organ images. The wireless transmission device transmits the organ images outside the human body. The internal power supply provides electric power for signal transmission after the cable and the image capturing and transmission device are separated.
