    • A direct-coupling control method capable of improving fuel efficiency by performing slip direct-coupling control of a torque converter, in which a driving force transmission of an automatic transmission is operated under an approximate direct-coupling condition that permits slight slippage of the torque converter, in a predetermined operating range of the automatic transmission such as a low speed range thereof, and capable of positively detecting and preventing direct-coupling vibration caused by deterioration of hydraulic oil or the like. In the slip direct-coupling control, an occurrence of direct-coupling vibration is detected when a variation of a slip amount changing beyond predetermined upper and lower limit values is found a predetermined number of times during a predetermined period of time, or when a variation in the rotational rate of the output shaft of the torque converter still continues even after the slip direct-coupling control is interrupted for the reason that the rotational rate has varied beyond a permissible range. Upon detection of the direct-coupling vibration, the slip direct-coupling control is inhibited.
    • 一种直接耦合控制方法,其能够通过执行变矩器的滑动直接耦合控制来提高燃料效率,其中自动变速器的驱动力传递在允许变矩器轻微滑动的大致直接耦合条件下操作 ,在其低速范围的自动变速器的预定操作范围内,并且能够积极地检测和防止由于液压油等的劣化引起的直接联接振动。 在滑移直接耦合控制中,当在预定时间段内发现改变超过预定上限和下限值的滑移量的变化预定次数时,或者当变化 即使在滑差直接耦合控制被中断之后,由于转速已经超出允许范围的原因,变矩器的输出轴的转速仍然持续。 在检测到直接耦合振动时,禁止滑动直接耦合控制。

    • A method of purifying a copper electrolytic solution circulated in a copper electrorefining system, wherein a portion of the solution is withdrawn and recycled to the system after purification treatment. The purification treatment includes the addition of a hydrosulfide to the withdrawn solution to generate only the necessary quantity of hydrogen sulfide gas required in the reaction. The hydrogen sulfide gas generated is utilized for purification treatment. One process comprises dividing the solution withdrawn into two portions. Sodium hydrosulfide is added to the first portion to precipitate and separate metals as sulfides. Excess sodium hydrosulfide is further added to the first portion for reaction with residual sulfuric acid in the solution to generate hydrogen sulfide gas, then contacting the second divided portion with the hydrogen sulfide gas thus produced to precipitate and separate metals in the form of sulfides. The filtrate is then recycled to an electrorefining system. There is also provided a process comprising contacting the solution with hydrogen sulfide gas to separate and remove Cu, As, Sb and Bi in the form of sulfides from the solution, then dividing the solution into two portions; The first portion is recycled to the electrorefining system, whereas excess sodium hydrosulfide is added to the second portion to separate and recover Ni as nickel sulfide from the solution. Resultant hydrogen sulfide gas is used for contact with solution to be treated.
    • 一种纯化在铜电解精炼系统中循环的铜电解液的方法,其中一部分溶液在净化处理后被抽出并再循环至系统。 净化处理包括向所提取的溶液中加入氢硫化物以仅产生反应所需的必需量的硫化氢气体。 产生的硫化氢气体用于净化处理。 一个方法包括将溶液分离成两部分。 将氢硫化钠加入到第一部分以沉淀并分离作为硫化物的金属。 进一步向第一部分加入过量的氢硫化钠以与溶液中的残余硫酸反应以产生硫化氢气体,然后使第二分开部分与由此产生的硫化氢气体接触以沉淀并分离硫化物形式的金属。 然后将滤液再循环至电解精炼系统。 还提供了一种方法,其包括使溶液与硫化氢气体接触,从溶液中分离并除去硫化物形式的Cu,As,Sb和Bi,然后将溶液分成两部分; 将第一部分再循环至电解精炼系统,而将过量的氢硫化钠加入到第二部分中以从溶液中分离和回收作为硫化镍的Ni。 所得硫化氢气体用于与待处理溶液接触。
