[Title of the Invention]
Flexible tubular waveguide and its reinforcement
[Claims]
1. Flexible tubular waveguide, comprising metal transmission tube (1) with plastic covering
(2), with ring-like indentations (5) placed in a cyclic manner, thus obtaining flexibility in the
tubing. (See Figure 3 (1) and (2))
2. Heat-shrink piping part for the flexible tubular waveguide reinforcement described in Claim
1 to be deployed on the inside wall of the metal transmission tube (1) described in Claim 1,
and further having the indentations that fit into indentations (5) of said metal transmission
tube (1) in a cyclic manner on its outside. (See Figures 1 (3) and 3 (3))
3. Heat-shrink piping part for the flexible tubular waveguide reinforcement which fits into
heat-shrink piping part described in Claim 1for the flexible tubular waveguide
reinforcement to be fitted into the bore of the metal transmission tube (1), described in
Claim 1, and further has the indentations that fit into indentations (5) of the said metal
transmission tube (1) in a cyclic manner on its outside. (See Figure 2 (4))
[Excerpt from Detail Description of the Invention and Drawings]
This invention concerns the tubular waveguide and its reinforcement material.
The conventional tubular waveguide was highly rigid piping connected by connective
flanges, but this invention, which is tubular waveguide is flexible and can be coiled on the
drums and also can be continuously manufactured. It also transmits electromagnetism more
efficiently as compared with rigid waveguide.
The reinforcement of this invention maintains the shape of the waveguide when coiled on
a drum.
After installation, hot air is blown into the waveguide to heat shrink the reinforcement and
pulled out.

[Explanation]
The related invention (Claims 2, 3), the reinforcement equipment, effects the function of
the flexible tubular waveguide without changing the tubular waveguide. The specified and
related inventions, therefore, are the product and a product for handling the product.
