摘要： A tooth-skipping prevention mechanism includes a block, which is inserted displaceably into a first end block in an electric actuator. A cavity having a semicircular shape in cross section is formed in one end of the block facing toward an outer circumferential side of a drive pulley and recessed toward another end side of the block. In addition, the cavity is arranged at a predetermined distance with respect to an outer circumferential surface of a timing belt that is enmeshed with the drive pulley. When the timing belt is moved in a radial outward direction so as to separate away from the drive pulley, movement of the timing belt is restricted, whereby the enmeshed condition of the timing belt and the drive pulley is maintained.

摘要： A method of solvent extraction of a nickel sulfate solution uses a multi-stage, counter-current, organic solvent extraction system composed of at least two extractors connected in series, and includes a first extraction step of feeding a crude nickel sulfate solution that contains sodium and ammonium impurities into a second-stage extractor, wherein it is treated in countercurrent flow and at a pH of 6.5 to 7.0 with an organic extractant fed into the second-stage extractor from the first-stage extractor, to thereby extract some of nickel in the crude nickel sulfate solution into the organic extractant; and a second extraction step of transferring the nickel-containing, organic phase to an organic phase-scrubbing step to remove sodium and ammonium, while transferring the nickel sulfate solution, from the first extraction step and from which some of nickel has been removed, to the first-stage extractor, wherein it is treated in countercurrent flow and at a pH of 5.5 to 6.5 with a fresh organic extractant, to thereby extend the remaining nickel in the nickel sulfate solution into the organic extractant. The nickel-containing organic phase from the second extraction step is divided into two portions, one portion being fed into the second-stage extractor while the other portion is transferred to a by-pass, organic phase-scrubbing step it to remove sodium and ammonium.
