Abstract: PURPOSE:To miniaturize the air supply section on the upstream side of a combustion chamber and attempt to improve combustion characteristics by providing the inlet port of a tail pipe of a pulse burner and the inside of the air supply pipe with aerodynamic valves which have different flow coefficients according to the direction of flow. CONSTITUTION:Fuel and air are supplied into the combustion chamber 11 of a pulse burner from an air supply pipe 13 and fuel supply pipe 14, and when this mixture of the air and fuel is ignited, an explosive combustion occurs, and the expanded combustion gas. goes down to the downstream side and upstream side. At this time from the relation of the flow coefficients of aerodynamic valves 18 and 19 provided on the upstream side and on the downstream side a large proportion of the combustion gas is discharged through a tail pipe 12 via the valve 19 which has a large flow coefficient. When the explosive combustion process is finished, the pressure in the combustion chamber becomes lower than the surrounding pressure by the inertia force of the combustion gas in the tail pipe 12 and a suction process is started. At this time much of fresh air passes through the valve 18 on the upstream side, and with the fuel that is jetted out from the downstream side of the valve the fresh air is led to the combustion chamber 11. And then an explosive combustion occurs again and this cycle is repeated from this time on.

Abstract: PURPOSE:To improve a heating effect, as well as contrive to produce a thin type burning equipment by a method wherein a rear side surface body of an outer cylinder faced to the secondary red heated body is constituted with a heat-reflection material member. CONSTITUTION:A radiation heat is emitted to all over surroundings without sheltered part from the secondary red heated body 20. However, almost of the radiation heat is transferred to a front and rear side direction because of the reason the flat-shaped plate of the secondary red heated body 20. And the radiation heat in a backward direction is forced to reflect its direction with a layer of a heat-ray reflecting material member 22, which is formed inner side surface of the outer cylinder 21, passing through a opened holes unit 20a of the secondary red heated body 20, and is discharged into a foward direction. Further, due to a synergestic effect of a straight moving radiation heat from the red heated body 20, a higher rate of radiation heat is supplied through a heat-resisting glass 23. In addition to the above, the visible ray has a similar effect of heat reflection, which eliminates a shadow portion of the opened holes unit 20a, thereby a heating effect in terms of a visual sense is sufficiently improved. Further, design consideration on heat resisting capability to the rear side plate of the cylinder is no longer required, consequently a thinner plate is available for the burning equipment.

Title: Production of water with surface active function and reducing function strengthened and activated hydrogen enriched
Inventor: KOBAYASHI HISAO
IPC: C02F1/46
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To generate activated hydrogen in water by installing a screen-shaped inactive metal electrode immediately downstream from a magnetic field area and supplying electrons from an external power source. SOLUTION: A magnetic field area is formed by installing a permanent magnet in the discharge side conduit of the circulating pump of a water circulating system having a circulating circuit which takes out water from a water storage tank and returns the water again to the tank. When the pump is operated in this state, water molecules are ionized by an electromagnetic induction action generated by the permanent magnet and a water flow. In this process, a screen-shaped inactive metal electrode is installed immediately downstream from the magnetic field area, and when electrons are supplied from an external electrode, only hydrogen cations can be eliminated selectively. The hydrogen ions are converted into hydrogen atoms, or activated hydrogen. The active hydrogen remains in an atomic form for a while. As a result, the prepared water functions as water containing active hydrogen while keeping the reducing function of hydroxyl ions.

IPC: C04B35/581
Filed: 1992-09-02
Abstract: PURPOSE:To provide an aluminum nitride sintered compact excellent in heat conductivity and insulating property and low thermal expansion coefficient free from a layer different from the other part and having uniform characteristics. CONSTITUTION:When an aluminum nitride sintered compact is produced by sintering, operation for destroying the equilibrium state of a reaction on the surface of a compact to be sintered is carried out during sintering so as to prevent the stop of progress of sintering due to an apparent equilibrium state attained by the confrontation between the partial pressure of gaseous N2 in the sintering atmosphere and that of gaseous CO generated by reduction. Since the reaction can be allowed to proceed further, the compact to be sintered reacts sufficiently and difference in characteristics between the interior and surface part of the compact is not produced.
