Title: Flame holding body for gas burner of premixing type
Inventor: MIURA TAMOTSU
IPC: F23D14/74
Filed: 1989-06-30
Abstract: PURPOSE:To form stable flames by providing many projection on the surface of a flame holding body which injects a premixture gas from many injection holes provided in the flame holding body and forming combustion flames on its surface. CONSTITUTION:A flame holding body 10 of a flat plate shape, made of ceramics, etc., which has many injection holes 11 formed is provided with many projections 20 on the side of the combustion face. The projection 20 has a shape provided with a head section 21 of flat sphere shape and a neck section 22 of a columnar shape. As the speed of injection of a premixture gas from the injection hole 11 is raised, vortex flows are created on the back side of the head section 21 of the projections 20, and small flames are formed so as to be covered on both sides by large flames. In these conditions, even if the speed of injection of the premixture gas goes in the range of speed in which flames of conventional burners for premixture gases are lifted or blown off, the flames downstream of the projections 20 are held stably, and the flames downstream of the injection holes 11 are successively ignited by the flames and the whole burner flames are always held stably.

IPC: G01N27/12
Filed: 1979-12-27
Abstract: PURPOSE: To make a semiconductor gas sensor extremely compact by arranging three conductors on the main surface of an insulator, in which a gas sensitive body is placed between the first and second conductors while a resistance is provided between the second and third conductors.  
     CONSTITUTION: A thick film resistor is printed zigzag on the main plane of an insulator substrate 20 to form a heat generating body 21 while made electrodes 21a and 21b at both ends thereof. Then, an insulating layer 22 is formed on the substrate 20 and the heat generating body 21 without covering the terminals 21a and 21b. Then, thick film conductors 23aW23c are formed on the substrate 20 and the insulating layer 22 while electrode terminals 24a and 24b are respectively provided on each one of the conductors 23a and 23b. Subsequently, detection electrode terminals 25a and 25b are respectively provided on the other ends of the conductor 23b and the conductor 23c. The conductors 23a and 23b are bridged to form a gas sensitive body 26 printed and the electrode terminals 23a and 23c are bridged to form a thick film resistor 27 printed. While the heat generating body 21 gives the sensitive body 26 an optimal temperature for the gas detection, changes in the voltage are detected with the terminals 25a and 25b the moment the sensitive body 26 senses gas. The existence of gas can be found.

IPC: B41F31/14
Filed: 1986-07-21
Abstract: PURPOSE:To promote the evaporation of emulsified water, by electrically earthing at least one metal roller among a large number of rollers constituting inking arrangement and connecting a high voltage generator to a roller electrode. CONSTITUTION:A roller 12 made of a metal is earthed electrically. An electrode roller 28 is contacted with the roller 12 through an ink membrane under proper pressure and is a freely rotating roller rotating so as to follow the rotary power of the roller 12. When the electrode roller 28 rotates with the rotation of the roller 12, high voltage is applied to the ink membrane interposed between the roller 12 and the electrode roller 28 by a high voltage generator 23. Whereupon, fine water droplets of dampening water are flocculated to grow and a large amount of surface water is generated in the nip parts of form rollers 17, 18 and the roller 12. Therefore, evaporation is promoted and it is unnecessary to evaporate and remove dampening water penetrated in inking arrangement by a large number of ink distributing rollers and the number of the rollers can be reduced thereby contributing to cost reduction.
