    摘要： An optical transmission module has: an optical module having an optical element and a receptacle portion; a circuit board that is electrically connected to the optical module through an electrical connection member; and a housing in which the optical module and the circuit board are placed. The optical module is in surface-contact with and fixed onto the housing. The receptacle portion and the circuit board are not in contact with the housing. The receptacle portion is restricted in position while having a positional degree of freedom at least in a direction perpendicular to an optical axis of light emitted from the optical element. The circuit board is restricted in position while having a positional degree of freedom at least in a direction of the optical axis.

    摘要： A process for the preparation of monohydric alcohols by contacting a monoolefin of 2-4 carbon atoms with an aqueous solution containing a heteropoly-acid ion, thereby subjecting the olefin to a hydration reaction, characterized in that said aqueous solution contains the heteropoly-acid ion in a concentration of at least 1/40,000 mol per liter and has a pH ranging from 2.0 to 4.5, and the aqueous solution is heated to a temperature sufficiently high for initiating the hydration reaction, while the free iron ion concentration therein is maintained at not higher than 10 ppm substantially throughout the whole hydration reaction period.
