摘要： A fixing structure wherein impact transmitted to a housing is efficiently transmitted to a circuit board and strain etc. generated at the housing are not transmitted to the circuit board. The fixing structure includes a circuit board mounting electronic devices, a housing storing the circuit board in the inside, and a plurality of board mounting seats provided at the housing for fixing the circuit board. Part of the plurality of board mounting seats rigidly mount the circuit board to the housing. Due to this, the impact is transmitted well to the electronic devices. The remaining board mounting seats are formed so as to flexibly mount the circuit board to the housing. Due to this, the strain generated at the housing is no longer transmitted to the circuit board and destruction of the circuit board can be prevented.

The invention is characterized by (1) carrying out a reaction of an alcohol, carbon monoxide (CO) and oxygen in a reactor and withdrawing a gas (i) which contains CO and CO.sub.2 produced as a by-product of the reaction from the reactor; (2) contacting the withdrawn gas (i) with an alcohol solution so that at least part of the CO.sub.2 contained in the gas (i) is absorbed by the alcohol solution and removed from the gas (i), thereby obtaining a CO-containing gas (ii), and (3) recycling the CO-containing gas (ii) to the reactor. It is preferred that the gas (i) is subjected to vapor-liquid separation and a separated gas is contacted with the alcohol solution.
