Abstract: PURPOSE:To facilitate phase alignment by dispensing with a pilot gear and to improve workability, by providing a small tooth form between a large addendum tooth form and a dedendum tooth form and setting a simultaneous intermeshing rate to 1 or more. CONSTITUTION:An addendum 10 having a large tooth form of a curve A-B of rotors 1, 2 is set to a cycloid curve wherein a pitch circle is a rolling circle and a dedendum 11 is set to a trochoid curve of a curve H-J to bring point other than a point H to a non-contact state and an intermediate part is set to a small tooth form 12 and a simultaneous contact rate is set to 1 or more. Since seal points are set to C1-P-C2', C2-P-C1' and b1-P-b2', b2-P-b1', the variation of rotary torque due to fluid pressure difference P1-P2 is made min. to smooth rotation. Since discharge quantity is made large, miniaturization is achieved and, since an intermeshing rate is enlarged, a pilot gear is made unnecessary and a structure can be made simple and assembling can be made easy.

IPC: F27D1/16
Filed: 1987-07-30
Abstract: PURPOSE: To improve refractoriness of sticking matter, to improve thereby a strength of joining to a maintenance layer and, besides, to prevent a drop in a furnace of molten matter by a method wherein low-melting sticking matter which sticks on a furnace wall part is melted so that impurities be vaporized, by jetting a burning flame from jet holes in the center of a nozzle part of a burner, and after the molten matter flows down, it is solidified at the position of flowing down by jetting a cooling gas from jet holes in the outer periphery of the nozzle part. CONSTITUTION: Cooling gas jet holes 4 surrounding burning flame jet holes 3 are connected to a compressed air supply pipe 11, while cooling water is sent into a nozzle part 2 from a support tube 5. Low-melting sticking matter 17 constituted of Na3 O and the like sticks in layers on the inside of a gas furnace wall 16 and, when a burning flame 18 is jetted from the jet holes 3, it is melted and flows out from a damaged place 21. In this process, low-melting impurities vaporize and refractoriness of sticking matter 17a rises. The sticking matter 17a in a state of flowing out is solidified by blowing a cooling gas 20 from the jet holes 4 against it.

Abstract: PROBLEM TO BE SOLVED: To suppress corrosion of a collector plate, cathode-gas passages, and the like, and increase power generating efficiency, by inputting values detected by oxygen concentration sensors provided in gas exhaust passages into a control part and, if a reference value is exceeded, passing an inert gas through gas supply passages by operating first and second flow valves. SOLUTION: The gases flowing through respective gas-exhaust passages 11, 12, 13 are measured by oxygen-concentration sensors 22, and measured values are inputted into a control part 23. That is, O2 concentrations of the gases are always monitored by the control part 23 by means of the oxygen- concentration sensors 22 for measuring the O2 concentration of a cathode gas or oxidizing gas 17G, that of an anode gas or fuel gas 18G, and that of a gas in a battery container 2. When a reference value is exceeded, the control part 23 increases the flow rate of N2 gas as inert gas for diluting the oxygen concentration by closing a first flow valve 24 and opening a second flow valve 25, thus increasing the amount of O2-diluent and decreasing the O2 concentration. The O2 concentrations are controlled within the range of 1% to 0.001% by the control part 23.
