Drive shaft and method of producing drive shaft

A drive shaft is configured by joining solid stub shafts formed of a medium carbon steel to both ends of a hollow tubular body formed of a medium carbon steel. When expressed as grain size number, the grain size of the hollow tubular body at joint parts where the hollow tubular body and the solid stub shafts are joined together ranges from #5 to #9, and the grain size of the solid stub shafts at the joint parts ranges from #10 to #12.

A modeling device is disclosed that easily projects characteristic information obtained from an object onto a differently-shaped object, even if the object, from which the characteristic information is obtained, has a complex shape. A modeling device in one embodiment of the present invention includes a virtually electrifying section to calculate an electric potential at a spot in a heart at the time when a predetermined voltage is applied to the heart, and a projecting section to project a fiber orientation onto a heart model created on the basis of shape information that is input to the input section. The projecting section specifies a spot to be a target of projection on the basis of the electric potential obtained by the virtually electrifying section. Use of the electric potential in specifying the spot makes it possible to easily project the fiber orientation onto any heart having complex and various shapes.

Provided are a tripod constant velocity joint, and a method and a device for assembling the joint. The opening of a through-hole formed in an inner member of the tripod constant velocity joint has formed therein a tapered, reduced diameter section having a diameter tapered from the opening toward the inside. A first annular groove is formed in the side wall of a driving power transmission shaft, and a clip serving as an engaging member is engaged with the first annular groove. A second annular groove is formed in the inner wall of the through-hole in the inner member. In inserting the driving power transmission shaft through the through-hole in the inner member, the tapered, reduced diameter section guides the shaft in such a manner that the clip is contracted toward the bottom surface of the first annular groove. The clip expands and contracts due to the elasticity thereof when the positions of the first annular groove and the second annular groove coincide with each other.

A wall-mounted device () which ensures easy confirmation of the mounting of a to-be-mounted-on-wall object on a wall surface or the like, and can prevent the to-be-mounted-on-wall object from falling off, and a timepiece having the device are provided. First, an attachment fitting () is fixed to the wall surface or the like by screws. Then, a hook part () of the attachment fitting () is hooked on a hanging part () of the wall-mounted device () while deforming an elastic plate member () inward. When deformation of the elastic plate member () is released, vibration occurs together with generation of a light impact sound at the time the elastic plate member returns from the deformed state to the original state. With a first bent part () of the elastic plate member () being in abutment with the hook part () of the attachment fitting (), the to-be-mounted-on-wall object is mounted on the wall surface or the like.

A flexible section is provided between a small-diameter tube section and a bellows section of a boot for a joint, and the flexible section has a greater flexibility than the small-diameter tube section. When a spline shaft is displaced so as to incline relative to a constant velocity joint, deformation stress acting in the boot is relaxed by allowing the flexible section to deflect (bend). This inhibits the inner wall surface of the small-diameter tube section from separating from the sidewall surface of the spline shaft.

Joint structure and boot for joint

A boot for a joint, wherein an equal-diameter part and thick-walled parts are formed on the inner peripheral wall of a large diameter tube part. A first tapered part extending from the equal-diameter part is continued with a second tapered part formed at the thick-walled parts in the circumferential direction. The diameter reducing ends of the first tapered part and the second tapered part are located at the same position, and a thin-walled part engaged with an annular groove formed in the outer member of a constant-velocity joint is continued with the diameter reducing end.
