Abstract: In a method of manufacturing a center electrode for a spark plug, a core member is press-fitted into a metal cup and, thereafter, a cold-forging process is performed to form a small-diameter portion at a closed end of the metal cup. The small-diameter portion is completely free from deformation which may occur during press-fitting operation. Thus, the small-diameter portion has excellent accuracy in shape. Furthermore, since the press-fitting is performed before the cold-forging of the small-diameter portion, it is possible to increase the press-fitting load or pressure to the extent that the core member and the metal cup are joined together with a sufficient degree of adhesion which will insure the a center electrode to have good thermal conductivity.

Abstract: Spring structures are subjected to pre-release and post-release annealing to tune their tip height to match a specified target. Post-release annealing increases tip height, and pre-release annealing decreases tip height. The amount of tuning is related to the annealing temperature and/or time. Annealing schedules are determined for a pre-fabricated cache of unreleased spring structures such that finished spring structures having a variety of target heights can be economically produced by releasing/annealing the cache according to associated annealing schedules. Selective annealing is performed using lasers and heat absorbing/reflecting materials. Localized annealing is used to generate various spring structure shapes. Both stress-engineered and strain-engineered spring structures are tuned by annealing.

The tapered axial bore is adapted to receive a receptacle such that the tapered surface bears against the receptacle. Moreover, the collar has a resilient device that engages the sleeve. The resilient device, the tapered axial bore of the sleeve, and the receptacle receive a connector.

The increasing axial force displaces the sleeve axially relative to the receptacle causing the tapered surface to exert a radial force on the receptacle.

Abstract: A method of manufacturing an electrode array has an elongate flexible carrier that is much more flexible in a first direction than in a second direction orthogonal thereto. The elongate flexible carrier is formed with a bias force that causes the array to flex in the first direction so as to assume the general spiral or circular shape of the scala tympani duct within the cochlea. The less-flexible direction is the direction that makes it difficult for the array to twist as it is inserted within the scala tympani duct. The bias force is sufficiently strong to cause the array to assume its preformed spiral shape even after being straightened during initial insertion into the cochlea. Electrode contacts, embedded into the carrier so as to be exposed along an inner or concave surface of the spiral, thus wrap snugly around the modiolus, thereby positioning the electrode contacts against the modiolar wall in an optimum position for stimulation.

Leads in a connecting element may be covered by an insulating jacket applied by a coating process, and the insulating jacket may in turn be covered by a conductive layer so that each lead becomes a miniature coaxial cable. This arrangement provides immunity to interference and facilitates operation at high speeds.

Abstract: A circular wire with a circular cross section is wound on a coil reel. When a winding-form motor rotates a winding form, the circular wire is pulled and drawn from the coil reel. Rectangular forming rollers press the circular wire, so that a rectangular wire with a rectangular cross section is formed. The rectangular wire is directly wound on the winding form to be formed into a rectangular-wire coil. Because forming rectangular wire and winding on the winding form are carried out in a sequence of contiguous processes, a separate process for removing torsion set of the rectangular wire is unnecessary. The rectangular-wire coil can be formed from inexpensive circular material wire by a simple and low-cost apparatus. It is also possible and preferable to make dimensions and a shape of the rectangular wire variable by controlling clearance widths between the forming rollers and tension acting on the rectangular wire that has passed through the rollers.
