Title: Safety device for combustion
Inventor: KOMORI MINORU
IPC: F23N5/24
Filed: 1980-06-23
Abstract: PURPOSE:To open a fuel supply valve and keep the fuel supply valve open under the normal burning condition with normal state of flame and as well as close the fuel supply valve to prevent the poisoning accident due to carbon monoxide under the condition of shortage of oxygen by a method wherein the opening and closing of the fuel supply valve is performed by the signal from a sensor, which generates voltage in accordance with the content of the inflammable gas constituent. CONSTITUTION:When the oxygen concentration of the air in the room, in which a burner is used, is normal, the flame formed on a secondary flame hole 3 is too short to reach to an exhaust introductory port 6 so that the oxygen concentration of the exhaust gas, which flows from the exhaust introductory port 6 made at the lower surface wall of an exhaust introductory box 5 into the interior of the sensor 4, is nearly normal. Conseaquently, from the sensor 1 is obtained all the time the voltage signal large enough to keep the fuel supply valve 9 in open state. On the other hand, when the oxygen concentration of the air in said room becomes low, the flame formed on the secondary flame hole 3 extends to reach to the exhaust introductory port 6 so that the oxygen concentration of the exhaust gas becomes extremely low. Consequently, the voltage signal sent from the sensor 4 to a control device 7 is smaller than the predetermined value, causing the fuel supply valve 9 to close.

Filed: 1988-04-06
Abstract: PURPOSE:To prevent the decrease of bondability due to attaching and depositing of scattered fine particles of a discharge electrode, by forming the discharge electrode to fuse-form a ball at the tip of a wire, by using a specified alloy. CONSTITUTION:A discharge electrode 16 to fuse-form a ball at the tip of a wire is formed by using tungsten containing yttrium or tungsten containing lanthanum. Since a copper coating film is hardly formed on the surface of the discharge electrode 16 formed by using the above alloy, the decrease of arc-start is restricted or restrained, and therefore a suitable discharging state is maintained between the discharge electrode 16 and a wire 2. As a result, a specified discharging energy is maintained, so that an adequate ball 22 is formed and excellent bondability is obtained.
