Title: Method for partly repairing pipe conduit from its internal surface
Inventor: YAMAGISHI KAZUO
IPC: F16L55/16
Filed: 1988-04-29
Abstract: PURPOSE:To enable repair to be performed without using an adhesive agent by inserting a repairing sleeve, made by shape memory resin, to a repaired part in a pipe conduit thereafter heating this repairing sleeve to be restored to a condition before the deformation. CONSTITUTION:A repairing sleeve 5 consists of shape memory resin having an outside diameter equal to an inside diameter or more of a pipe 1 further having a length larger than the outside diameter in the tubular lengthwise direction, and the repairing sleeve 5 is deformed so as to be contracted smaller than the inside diameter of the pipe 1, being inserted into the pipe 1 to its pin hole 2 part. Thereafter this repairing sleeve 5 is heated and restored to a condition before the deformation. Thus because the repairing sleeve 5 is forced to be self attached and fixed to the internal surface of the pipe 1, the pipe 1 can be repaired without using an adhesive agent.

Title: Combustion device for slurry fuel
Inventor: KAWAGUCHI YOSHITO
IPC: F23D11/38
Filed: 1984-05-30
Abstract: PURPOSE:To enable excellent dispersion of solid particles, by a method wherein a premixer, which is capable of freely controlling a mixing ratio of solid particles in slurry fuel, is located in a burner device body or in the vicinity thereof. CONSTITUTION:Slurry fuel F and steam S are fed to a premixing chamber 18, and a mixing ratio of fuel is regulated through regulation of a mixing ratio of the steam S per unit quantity of the fuel F. With decreased mixing ratio of solid fuel particles, viscosity of slurry is also decreased, and dispersion of the particles is improved during injection of a burner 15. In which case, since an excessive increase in a mixing amount of the steam causes reduction in combustibility, a mixing ratio will be determined in consideration of this point. A mixing ratio is adjusted through respective adjustment of flow rates of the fuel F and the steam S. In the fuel having a mixing ratio, regulation of which is completed, solid particles are dispersed by the steam S for spraying within a burner 15 and are injected.
