    Abstract: A process by which a fluorosulfonyl fluoride compound useful as, e.g., a material for ion-exchange membranes can be efficiently produced at low cost without structural limitations while eliminating difficulties in production. The process comprises reacting XSO2RA-E1 (1) with RB-E2 (2) to obtain XSO¿2?R?A-E-RB¿ (3), reacting the compound (3) with fluorine in a liquid phase to obtain FSO¿2?R?AF-EF-RBF¿ (4), and decomposing the compound (4) to obtain FSO¿2?R?AF-EF1¿ (5). In the formulae, RA represents a divalent organic group; E1 represents a monovalent reactive group; RB represents a monovalent organic group; E2 represents a monovalent group reactive with E1; E represents a divalent connecting group formed by the reaction of E?1 with E2; RAF¿ represents a divalent organic group formed by the fluorination of RA, etc.; RBF represents the same group as RB, etc.; EF represents a divalent connecting group formed by the fluorination of E, etc.; EF1 represents a monovalent group formed by the decomposition of EF; and X represents a halogen atom.

    Abstract: A method for producing a fluorine-containing alkyl ether is disclosed wherein a sufficient reaction rate can be attained even under mild conditions. This method enables to efficiently perform post-processes such as distillation following the reaction. After introducing a polar non-protic solvent, a fluorine-containing ether, a catalyst, a fluorine-containing alkyl alcohol and a fluorinated olefin into a reaction vessel, the fluorine-containing alkyl alcohol and the fluorinated olefin are reacted with each other so as to produce a fluorine-containing alkyl ether. In this method for producing a fluorine-containing alkyl ether, the mass ratio between the polar non-protic solvent and the fluorine-containing ether introduced in the reaction vessel (polar non-protic solvent/fluorine-containing ether) is from 5/95 to 80/20.

    Abstract: An optical head comprising a voltage-supply phase correction device for continuously varying the wave front profile of light emitted from a light source in a plane. An anisotropic optical medium is held between a pair of substrates each having a surface provided with an electrode for applying a voltage to the anisotropic optical medium. Two or more power supply parts are formed in different positions on at least one of the electrode, thus fabricating a phase correction device where a different voltage is supplied to each power supply part. The phase correction device is disposed between the collimating lens and the quarter-wave plate of the optical head. The optical head has a decreased number of control circuits for supplying a voltage to the phase correction device for varying the wave front profile continuously. Such a phase correction device having two or more power supply parts electrically connected through a thin film resistor made of a conductive thin film is fabricated and built in an optical head.
