    摘要: A process is disclosed to produce an .alpha.-hydroxyiminophenylacetonitrile of the general formula [II]: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and Z are each as defined in the specification, characterized in that a crude nitrile containing a phenylacetonitrile of the general formula [I]: ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 and Z are each as defined in the specification, is reacted with an alkyl nitrite in the presence of a base, after which the reaction mixture is extracted with water and then the separated aqueous layer is neutralized with an acid. According to this production process, the desired .alpha.-hydroxyiminophenylacetonitrile can be produced with high purity, in high yield and with ease by extracting the reaction mass with water and then neutralizing the separated aqueous layer with an acid.

    摘要: A connector having a plug and a socket for receiving the plug. A first lock mechanism for locking the plug at a short inserting position, and a second lock mechanism for locking the plug at a long inserting position are provided. An indicator is provided for indicating a locked state by the second lock mechanism, thereby providing information that the plug is in an incomplete locking state.
