    摘要: There is disclosed an improved method of treating a spent electrolyte of copper from a cell for electrolytic refining of copper for the purpose of purification and reuse of the spent electrolyte. The process comprises the steps of: pretreating the spent electrolyte for removing copper therefrom until the copper content is greatly reduced but still remains at a level which is substantially higher than the total content of various metal ion impurities, preferably to a concentration of 10-13 g/l of Cu; blowing a hydrogen sulfide gas into the pretreated solution at a temperature of 40.degree. C. or higher until the redox potential of solution becomes a certain predetermined value to precipitate metal ions; filtering the treated solution to separate the residue available as a raw material for copper smelting from a filtrate which consists essentially of sulfuric acid; and returning the filtrate to the cell for electrolytic refining of copper.

    摘要: A side stand switch includes a case member having a fixed contact; and a rotor body having a moving contact that can come into contact with the fixed contact, mounted by tightening a securing bolt, and turned together with a side stand bar with respect to the case member. The rotor body has an engagement pin inserted therein and to be inserted into an engagement hole formed in the side stand bar. A width of the engagement pin in the turning direction of the rotor body is larger at a base portion inside the rotor body than at a tip portion protruding from the rotor body.
