  • Leadframe-based optical assembly

    A leadframe-based optical assembly is disclosed which is suitable for use with either transmitter or receiver optical assemblies. The leadframe includes a number of separate sections, each leadframe section being associated with a separate optical assembly. A particular leadframe section includes a first contact lead with an aperture therethrough such that the active region of the optical may be aligned with the aperture. A first electrical connection is made between the first lead and the optical device surface containing the active region. The remaining electrical connection is provided by a second contact lead which is wire bonded to the opposing surface of the optical device. A fiber section (fiber-containing ferrule) is attached to the opposite side of the leadframe in the vicinity of the first contact aperture to provide coupling between the optical fiber and the active region. Lensed fibers and/or semiconductor optical devices may be used to increase coupling efficiency.

  • Fork for barbecuing and open fire cooking

    A short generally cylindrical base is provided and an elongated shank has one end supported from and projects endwise outwardly from one end of the base. A follower is mounted on the shank for adjustable positioning therealong between a retracted position closely adjacent the base and an extended position remote from the base. A pair of elongated generally parallel tines are supported from the follower, on opposite sides of the shank, and generally parallel the shank with the tines projecting endwise outwardly from the follower in the same direction in which the shank projects from the base. A tubular combined handle and cover is provided and is closed at a first end thereof and the second end thereof and the base include coacting bayonet connection structure for supporting the cover from the base in selected end-to-end reversed positions. In a first position of the handle and cover, the latter defines a handle projecting endwise outwardly from the base in a direction opposite to the direction which the shank extends. In the second position of the handle and cover, the latter is telescoped over the shank and the tines, when the follower is in the retracted position, and completely encloses the shank and tines.
