Title: Method for preventing propagation of fluctuation in pressure of combustion furnace
Inventor: HASHIMOTO HIDEO
IPC: F23G7/06
Filed: 1989-07-21
Abstract: PURPOSE:To prevent propagation of the fluctuation in a pressure of a combustion furnace to a noxious exhaust gas generating source by a method wherein noxious exhaust gas is sucked to an ejector through which pressure drive gas is injected and taken out as gas mixed with drive gas through an ejector, and the mixture gas is introduced to the combustion furnace. CONSTITUTION:An ejector 28 comprises a nozzle part 29, a suction chamber part 30, and a diffuser part 31. When pressurized drive gas (a) is injected through a nozzle 33, a suction chamber 34 is brought into a pressure reduced state, and exhaust gas (b) is sucked, and as the two gases are violently mixed together, the mixture passes through a diffuser 35. When exhaust gas passing through an ejector is introduced to a burner 12 to effect combustion disposal, even when a fluctuation in a pressure is produced in the combustion furnace of a combustion disposing device, propagation of the fluctuation in a pressure is shut off by means of an ejector 28, and the fluctuation in a pressure is not propagated to the upstream side of the ejector 28. Thus, the fluctuation in a pressure can be prevented from propagation to a noxious exhaust gas generating source. Nitrogen, hydrogen, methane, and propane gas are used as drive gas for the ejector 28, the pressure thereof may be set to a value 2-15 times as high as a pressure at the outlet of the diffuser and 1-10 times as high as a sucked exhaust gas pressure.

Title: Shower head water stopper with water saving function
Inventor: TANAKA NARIO
IPC: B05B1/30
Filed: 1995-06-22
Abstract: PURPOSE: To make it possible to easily save, pass and stop water by constituting a shower head water stopper in such a manner that the operation to pass and stop water is carried out by a changeover lever and a water flow rate is controlled by bore control of a flow rate adjusting hole. CONSTITUTION: A shaft 4 is rotated by the changeover lever 3 after opening of a faucet at the time of use. The adjusting hole 5 existing at the shaft 4 and a water flow path 2 are aligned. Both are vertically passed through each other to induce water pass and showers are emitted from the head. The water pass is stopped when the changeover lever 3 is set at a misalignment position. The water is easily passed and stopped while the head 1 is held in the hand by the operation. The lateral movement of the changeover lever 3 in place of rotation is equally well. The water pressure does not drop even if the water is saved by, for example, about 20% in such a manner. There is a difference between a head position and a temp. and water mixing faucet position during showers use with the conventional constitution and if a main cock is stopped during the course of use, the readjustment of the temp. is needed but the temp. change at the time of reuse is prevented with the constitution.
