Abstract: A vehicle door lock device includes: a first member moving from an initial position to an actuated position so as to switch a latch mechanism, from a latched state to an unlatched state; a second member moving between a mechanical link position and a mechanical link cut position; a third member linked to the second member and holding the second member at the mechanical link cut position and holding the second member at the mechanical link position; a driving force source selectively moving the third member to one of the first and second positions; an operating member moving from an initial position to an actuated position, and moving the third member from the first position to the second position; and a control unit driving the driving force source. The control unit drives the driving force source to move the third member from the first position to the second position.

Abstract: A method for producing a metal salt by electrolysis in an electrolytic cell comprising an anode compartment and a cathode compartment partitioned by a diaphragm, characterized by supplying to the cathode compartment an aqueous solution of a water-soluble metal compound, and electrolytically reducing metal ions or metal complex ions to electroplate the metal on a cathode, wherein the diaphragm is a fluorinated anion exchange membrane made of a copolymer having repeating units of the formula: ##STR1## wherein X is F or CF.sub.3, l is an integer of from 0 to 5, m is 0, or 1, n is an integer of 1 to 5, each of p and q is a positive number and the ratio of p/q is from 2 to 16, and Y is a group involving a quaternary ammonium group.
