摘要： The bidirectional differential clutch enables to transmit or cutoff both clockwise and counterwise rotation at the input side. The clutch comprises an input gear having a first cylindrical surface, an output gear having a second cylindrical surface disposed with a space to the first cylindrical surface so as to be relatively rotatable, a plurality of engaging members interposed in the space, a holding member inserted into the space, the holding member having a pocket storing the engaging members, the engaging members being for operation from a neutral position in which both cylindrical surfaces are not engaged with each other to an operational position in which both cylindrical surfaces are engaged with each other, a sub-gear producing differential velocity in correspondence to the rotation of the input gear, and the holding member being linked with the sub-gear to slide in a peripheral direction by the differential velocity to operate the engaging members to the operational position. The engaging members may be rollers or sprags.

摘要： In construction of a metalworking vise having a fixed base, a stationary jaw mounted atop the front end portion of the fixed base, a slide jaw arranged facing the stationary jaw, and a piston movable into a hydraulic chamber to raise its fluid pressure, a holder shaft provided at its front end with an axial extension defining the hydraulic chambers and a force magnifying mechanism is arranged in the fixed base near the stationary jaw. The specified location of the force magnifying mechanism allow generation of a large clamp force at high precision in clamping position without causing any substantial warping of the fixed base.

摘要： In the V belt type continuously variable transmission, after the output power from the prime mover has been transmitted to the input pulley shaft, two paths are operable to transmit the output power from the input pulley shaft to the output pulley shaft, two paths which are a main power transmitting path through a V belt engaged between the input pulley and the output pulley and a sub power transmitting path through the 2-way differential clutch. The drive ratio of the sub power transmitting path is set in a slightly smaller value than the maximum drive ratio of the main power transmitting path. When the movable input half pulley of the input pulley has been moved near the position of the maximum drive ratio in the main power transmitting path, the rotational speed of the output gear in the 2-way differential clutch become slower than that of the input gear, and as a result a rotational force is given to the output gear so that the output pulley shaft is rotated through the sub power transmitting path in addition to the main power transmitting path so that it becomes possible to increase driving power and accelerating force and also to decrease load to be added to the V belt.
摘要翻译： 在V带式无级变速器中，在来自原动机的输出功率已经被传送到输入滑轮轴之后，两个路径可操作以将输出动力从输入滑轮轴传递到输出滑轮轴，两个路径是 通过接合在输入滑轮和输出滑轮之间的V带的主动力传递路径和通过双向差速离合器的副动力传递路径。 副动力传递路径的驱动比被设定为比主动力传递路径的最大驱动比略小的值。 当输入带轮的可动输入半滑轮已经移动到主动力传递路径中的最大驱动比的位置附近时，二通差动离合器中的输出齿轮的转速比输入齿轮的转速慢 结果，向输出齿轮提供旋转力，除了主动力传递路径之外，输出滑轮轴也通过副动力传递路径旋转，使得可以增加驱动力和加速力，并且还可以 以减少要添加到V带的载荷。
