Title: Burner and fluid heating device using the same
Inventor: KEGASA AKISHI
IPC: F23D14/14
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To suppress the lifted flame and back fire and, at the same time, to increase the combustion load of a burner and reduce the generation of NOx, by expanding the combustion load range of the boiler by installing a tubing material through which a liquid can flow to the internal flow passage of the face member of the burner. SOLUTION: A burner 100 is a premix combustion type burner and provided with a face member 3 and a burner casing 7 which can supply a premixed gas 11. The face member 3 is formed in a grid-like state by arranging metallic tubing materials 1 in parallel and wire rods 2 closely to the materials 1. Because of the face member 3, the premixed gas 11 supplied to the burner casing 7 is burned on the top side of the member 3 through flame holes 8 which are the composed of the gaps between the tubing materials 1 and wire rods 2. Flames 14 partially become turbulent on the downstream side of the material 1 and rods 2 and form a flame eddy 15. The eddy 15 burns the unburned premixed as 11 jetted from the flame holes 8, resulting in continuous burning on the upper surface of the member 3.  Therefore, the occurrence of flame extinction due to a lifted flame can be suppressed and high-load combustion and low NOx combustion with an increased excess air ratio are achieved.

Title: Dust core, ferromagnetic powder therefor and production thereof
Inventor: MORO EIJI
IPC: B22F1/00
Filed: 1997-12-27
Abstract: PROBLEM TO BE SOLVED: To enhance the characteristics by adding titanium oxide sol and/or zirconium oxide sol and phenol resin to ferromagnetic metal powder, thereby allowing high temperature annealing. SOLUTION: To form a uniform insulating film having high flux density and high insulation, using a small quantity of ferromagnetic metal powder by adding microparticles of titanium oxide sol and/or zirconium oxide sol dispersed uniformly into a solvent. When phenol resin is added furthermore, molding strength is enhanced and insulation does not deteriorate even if annealing temperature is raised to 800 deg.C or thereabout. Consequently, strains generated at the time of pulverization or molding are released, hysteresis loss is reduced because coercive force of a dust core is decreased, and core loss is reduced because insulation is sustained and eddy current loss is decreased. Furthermore, heat resistance resin is cured through annealing to increase density of a green compact thus enhancing mechanical strength.
