Abstract: PURPOSE:To make it possible to use the burner at a normal air excess ratio irrespective of the heat generation quantity of a gas by providing a two-stage combustion system of combining a catalytic combustion zone in which combustion is carried out at low temperatures by a high air excess ratio with an ordinary combustion zone. CONSTITUTION:In the main body 1 of a catalytic burner, a catalytic combustion zone P consisting of a combustible gas duct 2 and a catalytic carrier 3 is formed at the center thereof, and a fuel gas flowpath 4 forms at the outer side thereof an annular flowpath via a combustion gas inlet nozzle 10.

At the ultimate stream a ceramic carrier 5 exists which has an exhaust port 6 generating a high-temperature and complete combustion gas. Air 12 is required for the entire burner, and ordinarily the full quantity having excess air is passed through a catalytic zone. However, since the combustion gas exists in a part, the combustion temperature in the catalyst carrier 3 is kept at a low value. On the other hand, a residual fuel gas 14 passes through a nozzle 10 via an adjusting valve 11, and is mixed with a combustion gas generated in the catalyst carrier 3 in the mixing zone 7, and complete combustion is carried out ultimately in the ceramic carrier 5 by residual air.

Title: Hollow metallic light guide
Inventor: HONGO AKISHI
IPC: B23K26/064
Filed: 1989-03-27
Abstract: PURPOSE:To suppress the strain by the internal stress remaining in a thin film and to enhance the stability of the thin film as well as to improve the flexibility of the hollow light guide by forming the metallic layer to constitute the light guide of a composite layer of a dull nickel plating and bright nickel plating. CONSTITUTION:The metallic layer 40 constituting the hollow light guide is formed of the composite layer of the dull nickel plating 41 and the bright nickel plating 42. Although the compressive stress remains in the germanium layer 43 and bright nickel plating layer 42 formed by a sputtering, the internal stresses are negated by each other between these two layers and the dull nickel plating 42 inserted by these layers, by which the stable film is formed. The film thicknesses of the germanium layer 43 and the dull nickel plating layer 41 are sufficiently thinner than the bright nickel plating layer 42 and are below several microns. As a result, the mechanical strength of this hollow light guide is nearly determined by the bright nickel plating layer 42. The hollow light guide which is less plastically deformed even when bent repeatedly and has flexibility is obtd. in this way.
