Abstract: PROBLEM TO BE SOLVED: To facilitate a turning operation to the release position side of a push member after securing connection reliability. SOLUTION: A push member 3 is turnably supported between a release position and a push position by a turn shaft 33 in a housing 1. A lock column 13 inside which the small width portion 36 of a lever 32 is fitted is erected in the housing 1. A locking protrusion portion 37 is protruding provided on the outer face of the small width 36. A temporary lock recessed portion 50 and a real lock recessed portion 51 are formed up and down on the inner face of the lock column 13, and the temporary lock recessed portion 50 has shallower fitting depth. Before the mounting of the housing 1 on a circuit board, the push member 3 is turned just before the push position so that the lock protrusion portion 37 is locked with the temporary lock recessed portion 50.  When a ribbon cable is put in connection, although the push member 3 is turned to a release position, temporary lock force is weak so that the push member 3 can be easily turned. At the pressing position, the lock protrusion portion 37 is fitted into the real lock recessed portion 51 so as to lock firmly.

Abstract: PURPOSE: To refine a high purity high Cr alloy by combining granulation of a Cr source required for ultra low nitriding with treatment of the resulting granular raw material with a CaO type flux at the time of melting.  
     CONSTITUTION: Metallic chromium, ferrochromium, or the like is regulated to an average granular size of 1W6mm and heated under a non-oxidizing atmosphere such ase Ar together with a flux of alkaline earth metal-alkali (earth) metal hailde type, e.g. Mg-CaCl 2  type flux. The heating temp. is pref. 900W1020°C. The heated material is then cooled and treated with water to convert Mg and Ca remaining in the flux into their hydroxides and to dissolve the halide component contained in the flux in the water. The nitride in the flux reacts with the water to be convereted into NH 3 , which is immediately absorbed in the water. As a result, the granular material separates from the flux, and it is washed with water to reduce the sticked chloride and hydroxides, and dried. The ultra low nitrogen granular Cr source thus obtd. is mixed with a CaO type flux and melted under reduced press
