IPC: F23C99/00
Filed: 1980-10-28
Abstract: PURPOSE: To conduct low NOx combustion in the captioned combustion method under conditions of a specific temperature and oxygen concentration by a method wherein a plurality of groups each of which is composed of a main burner, an additional fuel injector, an additional air injector are provided and each of a plurality of the injectors is synchronized with a main burner in their operation.  
     CONSTITUTION: Additional fuel injectors, additional air injectors belonging to the same group synchronize with the main burner in their starting and stoppage. Additional fuel jet 101 is blown into fuel producing gas G 511  wherein the temperature of the back flow of the flame 61 produced from the main burner 51 is 950W1,400°C and the concentration of oxygen does not exceed 5vol%. The quantity of the additional fuel 70 is adjusted so that the concentration of oxygen in said produced gas is reduced to approximately zero. The gas G 512  produced by this method gives heat to the wall of a burning furnace 100 to lower its own temperature and to burn completely combustion in the gas. The additional quantity of air is adjusted so that the combustion gas G 512  produced by such method contains oxygen of about 1.0W 1.5%.

Filed: 1985-07-09
Abstract: PURPOSE:To manufacture easily a forging die, and also to reduce expenses by forming parts by the forging die which has been forged by using a base material corresponding to a shape of parts to be forged, as a male die. CONSTITUTION:A base material of a shape corresponding to parts to be forged is manufactured by steel for a metallic die, and formed to an appropriate hardness by executing a prescribed heat treatment. A forging die which becomes a female die is forged by using the base material as a punch and punching the steel for a metallic die. As for the forging, it is desirable to execute it at a temperature of 600-850 deg.C. The inside surface of the forging die which has been obtained in this way is finished if necessary, and thereafter, the hardness is adjusted by executing the quenching and tempering. Desired parts are obtained by executing the forging by using the forging die to which a heat treatment has been performed. In this way, many forging dies can be manufactured by one piece of base material, therefore, a manufacturing cost of the forging dies can be reduced remarkably.

IPC: G09F3/00
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily identify the shape and patterns of a container as tactual information by printing the one surface of a heat shrinkable film with arbitrary patterns by using UV curing type ink, then forming this film to a cylindrical shape with its printed surface positioned to face outward and putting the film on the container. SOLUTION: The shrink label 3 formed by printing the one surface of the vinyl chloride resin film 1 with the patterns 2 in parallel in a longitudinal direction by using the acrylic UV curing type ink is formed to the cylindrical shape. The shrinkage rate of the printing ink of the patterns 2 is made lower by about 15% of the shrinkage rate of the film 1. Such label 3 with the printed surface of the patterns 2 positioned to face outward is put on the cylindrical part of the plastic container 5 for shampoo and is heated to shrink the film 1, by which the label is brought into tight contact with the container 5. The diameter of the cylinder of the label 3 is made larger by 3% than the diameter of the cylindrical part of the container 5.  As a result, the patterns 2 are formed in relief as the three-dimensional patterns and are distinctly tactually identifiable on both side parts of the container 5.
