摘要： PURPOSE:To eliminate the need for the use of an active flux and accompanying washing with CFC at reflow soldering. CONSTITUTION:An alcoholic steam generated in a bubbling device 7 is added to nitrogen gas 1 in a gas mixer 9 to obtain reducing atmosphere gas, which is released within a reflow soldering furnace to solder within the reducing atmosphere gas to reduce an oxidized copper membrane without using as active flux. Thus, as the reduction does without using the active flux, washing with CFC is not required. Further, as a small quantity of oxygen is allowed to mix, an attempt is made to save the high-priced nitrogen gas.

摘要： PROBLEM TO BE SOLVED: To early and accurately detect gases leaking in soil by preparing a uniform mixed gas out of fuel gas and helium gas, and feeding the mixed gas to a main branch pipe for detecting the helium gas after the leak and diffusion thereof. SOLUTION: A flow rate ratio control circuit 11 calculates and outputs a helium gas flow rate ratio corresponding to the flow rate of LP gas, in response to a signal outputted from a gas meter 7. Also, an automatic flow rate adjuster 10 makes the adjustment of the flow rate of helium gas, so as to keep a constant flow rate ratio of LP gas to helium gas, depending on a signal outputted from the circuit 11. Thus, the flow rate ratio of LP gas to helium gas is controlled at a constant value, and both of the gases are evenly mixed with a stationary mixer 8. Furthermore, a gas mixing device mixes both gases to a constant value on the basis of the constant flow rate ratio, and a mixture of the gases is supplied to an LP gas main branch pipe 3. When the mixed gas leaks at a leak position on the main branch pipe 3 in soil, helium gas having a high diffusion rate is quickly diffused. As a result, the leak position can be early and accurately identified with a detection means on the ground.

The equipment is constituted of a nitrogen gas flow rate control unit 5, a combustible gas flow rate control valve 6, a sampling line 7, a sampling pump 8, an oxygen densitometer 9 for judging the oxygen concentration in atmosphere, and an operator 10 which controls, on the basis of oxygen concentration in the furnace 1, the amount of combustible gas to be mixed with nitrogen gas so as to be 0.9-1.4 times the combustion reaction theoretical amount of oxygen amount in the furnace 1. Thereby the oxygen concentration in the furnace 1 can be reduced to be lower than or equal to 100ppm, with nitrogen amount of about 1/2-1/3 as compared with the prior art case.
