摘要： A boot for a high speed constant velocity universal joint having an articulation accommodating portion attached to the outer joint member of the universal joint and a contiguous linear displacement accommodating portion having its end connected to the inner joint member shaft. The junction between the articulation and linear displacement accommodating portions is reinforced to form a boot stabilizer at a point intermediate its opposite ends which inhibits eccentric spinning of the boot at high rotational speeds. The articulation accommodating portion has a first plurality of annular convolutes, the diameters of which diminish as a function of their displacement from the outer joint member. The linear displacement accommodating portion has a second plurality of annular convolutes having substantially equal diameters.

摘要： A damper device for a motor having a boss section attached to a rotary shaft of the motor, a mass inertia section rotatably supported by the boss section such that it surrounds the outer periphery of the boss section with a gap left therebetween, a magnetic fluid filling up the gap, and magnets provided in either the boss section or the mass inertia section for preventing leakage of the magnetic fluid. Furthermore, the boss section and the mass section facing each other through the gap are made of materials differing in the coefficient of thermal expansion, even if the magnetic fluid is heated by heating of the motor, an external temperature variation and the like so that its viscosity is decreased, such a decrease in viscosity can be canceled out by a change in gap dimension caused by the difference in expansion between the boss section material and the mass section material differing in the coefficient of thermal expansion. Therefore, the damping effect is kept constant without being influenced by thermal fluctuations.

摘要： A damper for use on a motor vehicle has a fluid cylinder, a piston axially slidable in the cylinder, and a piston rod secured to the piston. A seal incorporated in the damper includes an annular contacting portion held in contact with the outer peripheral surface of the piston rod and a resilient connecting portion having one end joined to the contacting portion and the other end secured to the inner peripheral surface of the cylinder. Due to the resiliency of the resilient connecting portion, the contacting portion is movable with the piston rod to a certain extent when the piston rod is moved with respect to the cylinder in a higher-frequency, smaller-amplitude range.
