Title: Method of removing polluted concrete
Inventor: TAKAHATA MASATO
IPC: B23K26/38
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a method of removing polluted concrete by which energy can be saved and the spread of pollution can be controlled and prevented. SOLUTION: A reflection mirror 2 is attached slantingly at the bottom of a vertical pipe 1. A high energy beam B is radiated from the surface of the mirror 2, and the high energy beam B refracted at the mirror 2 is radiated from a vertical hole 6 toward the side surface of a concrete layer to melt it. And, after the concrete layer is fused parallel to the surface with the energy beam B rotated parallel to the surface, the surface of the concrete layer is broken by hammering the surface lightly and the broken blocks are removed. If necessary, the vertical pipe 1 is moved to the outermost part of the cavity formed after the broken concrete blocks are removed, and the remaining concrete layer is repeatedly hammered in the same way to enlarge the removed area.  In this case, the depth of fusion in the part to which the vertical pipe is moved is secured by making the refraction angle of the high energy beam B refracted at the reflection mirror 2 a little narrower than 90 degrees. Pressurized gas sent into the vertical pipe 1 is blasted to the fused part to blow off smoke and broken pieces to secure the fusing efficiency.

Title: Detecting method for internal residue in steel pipe
Inventor: KANAYAMA ISATO
IPC: G01M99/00
Filed: 1990-12-12
Abstract: PURPOSE:To detect internal residues at a real time by radiating microwaves through a pipe end propagate the microwaves through a steel pipe, and calculating modulation of the frequency thereof and attenuation of a power. CONSTITUTION:Axes coincide with each other for setting in a state that a circular waveguide discharge port 3 is separated approximate 10mm away from a seam welded pipe 4, and a microwave receiving port 6 is set in a similar manner described above to the one pipe end. The microwave receiving port 6 is connected to a spectrum analyzer 8 and/or a microwave power meter 4 through a transmission cable 7. When a cut-off frequency is oscillated by means of a microwave oscillator 1 and microwaves are transmitted and received through a transmission cable 2, if remaining beads are present in a pipe, modulation of a frequency and attenuation of power transmission occur. Since even when the seam welded pipe 4 is not defective, it has slight unevenness in an outside diameter, thickness, and a bend, attenuation of microwave propagation and modulation of a propagating frequency occur, but they are approximately 5%. Attenuation of a propagation power and modulation of a propagating frequency are premeasured, a measuring result is compared with those occurring owing to remaining beads, and residues in a pipe is easily detected.
