    • There is disclosed a process for producing an aromatic amide compound of the general formula (4), including the steps of subjecting an o-nitrophenol compound of the general formula (1) to catalytic reduction in acetone or an aromatic hydrocarbon solvent under the presence of a nickel catalyst to give an o-aminophenol compound of the general formula (2); and (b) subjecting the o-aminophenol compound of the general formula (2) to condensation with an acid chloride compound having a sulfur content of 0.5% or less, based on the weight of the acid chloride compound, of the general formula (3) in acetone or an aromatic hydrocarbon solvent under an atmosphere of an inert gas having an oxygen concentration of 1% or less. The acid chloride compound having a sulfur content of 0.5% or less, based on the weight of the acid chloride compound, of the general formula (3) may be obtained by allowing a carboxylic acid compound of the general formula (5) to react with thionyl chloride and by concentrating the reaction mixture. Also disclosed is another process for producing an aromatic amide compound of the general formula (4), including the step of subjecting an o-aminophenol hydrochloride salt of the general formula (6) to condensation with an acid chloride compound having a sulfur content of 0.8% or less, based on the weight of the acid chloride compound, of the general formula (3) in an inert solvent.

    • A continuously variable transmission includes a first rotating element, a second rotating element, a rolling member, a support shaft, and a support rotating element. The support rotating element includes a fixed element provided with a first guide portion guiding a first guide end portion, and a movable element provided with a second guide portion guiding a second guide end portion. The support shaft is configured such that: either one of a moving distance of the first guide end portion and a moving distance of the second guide end portion at the time when the support shaft is tilted together with the rolling member is relatively large, and the other one of the moving distances is relatively small; and an outside diameter of that one of the first guide end portion and the second guide end portion which has a relatively large moving distance is relatively larger than an outside diameter of the other one which has a relatively small moving distance. This yields such an effect that the continuously variable transmission is able to realize a smooth change gear operation.
    • 无级变速器包括第一旋转元件,第二旋转元件,滚动元件,支撑轴和支撑旋转元件。 支撑旋转元件包括设置有引导第一引导端部的第一引导部的固定元件和设置有引导第二引导端部的第二引导部的可动元件。 支撑轴构造成:当支撑轴与滚动部件一起倾斜时,第一引导端部的移动距离和第二引导端部的移动距离中的任一个相对较大,并且 其他移动距离相对较小; 并且具有较大移动距离的第一引导端部和第二引导端部中的一个的外径相对大于具有相对较小移动距离的另一个的外径。 这产生了这样的效果:无级变速器能够实现平稳的换档操作。
