摘要： A constant velocity universal joint in which an outer member and an inner member are coupled through a cage member which has an outer spherical surface and an inner spherical surface. These spherical surfaces of the cage member are in contact with an inner spherical surface of the outer member and an outer spherical surface of the inner member, respectively. The cage member supports a number of balls in respective windows, and these balls are in engagement with respective pairs of longitudinally extending ball grooves formed in the inner spherical surface of the outer member and the outer spherical surface of the inner member. The bottom surfaces of the ball grooves extend substantially along respective circular arcs whose centers are located at equal distances on opposite sides of the center of the joint. The inner and outer spherical surfaces of the cage member are eccentric to one another and their centers are also located at equal distances on opposite sides of the center of the joint. The offset centers of the circular arcs and the offset centers of the spherical surfaces of the cage member are respectively coincident.

摘要： A constant velocity universal joint comprising an outer member having an inner spherical surface and an inner member fitted in the outer member and having an outer spherical surface facing the inner spherical surface of the outer member. The inner and outer members are adapted for relative angular travel about the center of the joint. A cage member is interposed between the inner and outer members and has an outer spherical surface facing the inner spherical surface of the outer member and an inner spherical surface facing the outer spherical surface of the inner member. The cage member carries balls in windows which project outwardly for engagement in respective opposed ball grooves in the inner and outer members. The mutually facing spherical surfaces of the outer member and the cage member are slightly eccentric with respect to one another so that a gap formed between the two spherical surfaces gradually decreases towards one end of the joint and the surfaces come into contact in a first contact zone, while the mutually facing spherical surfaces of the inner member and the cage member are slightly eccentric with respect to one from another so that a second gap formed between these two spherical surfaces decreases gradually towards the other end of the joint and these surfaces come into contact at a second contact zone. The first and second contact zones of the cage respectively with said outer and inner members maintain the cage in axial position in the joint.

摘要： A facet-forming layer made of nitride semiconductor containing at least aluminum is formed on a substrate made of gallium nitride (GaN). A facet surface inclined with respect to a C-surface is formed on the surface of the facet-forming layer, and a selective growth layer laterally grows from the inclined facet surface. As a result, the selective growth layer can substantially lattice-match an n-type cladding layer made of n-type AlGaN and grown on the selective growth layer. For example, a laser structure without cracks being generated can be obtained by crystal growth.
