Abstract: The information processing apparatus includes a computation processing circuit of which a state is capable of being switched at least between an active state in which power is consumed, and a no-power-usage state in which power is not consumed; an event detection module that detects a first event used to shift the state of the computation processing circuit from the no-power-usage state to the active state; a power isolation circuit that isolates power of the event detection module from power of the computation processing circuit in the no-power-usage state; and an isolation canceling circuit that cancels, in the active state, the isolation performed by the power isolation circuit.

Abstract: A composition for acid gas absorbent comprising:(A): 99.99 to 70 wt % of a polyethylene glycol dimethyl ether composition represented by the following formula:CH.sub.3 O(C.sub.2 H.sub.4 O).sub.n CH.sub.3wherein n is an integer of 1 to 10; and,(B): 0.01 to 30 wt % of a compound containing at least one of an --NH-- group, a phenolic --OH group and an --S-- group in one molecule thereof but free from an alcoholic --OH group, is provided. More particularly, component B may be an amine, preferably a secondary amine, or a phenolic compound.
