A space-saving in-flight trash compactor, comprising a trash chute, a compactor mechanism, and a storage chamber that includes an interface for the trash chute. Trash deposited in the trash chute is channeled into the storage chamber. Either or both of the compactor mechanism and the storage chamber are rotatably attached to one or two axles. During maintenance or trash removal, the compactor mechanism or storage chamber may swivel around an axle to permit ease of access.

A method for installing fragile, high temperature insulation batting in an elongated cavity or in a resilient wire sleeve to form a resilient seal. The batting is preformed to rough dimensions and wrapped in a plastic film, the film being of a material which is fugitive at a high temperature. The film is heat sealed and trimmed to form a snugly fit skin which overlaps at least at one end to permit attachment of a pull cord. The film absorbs the tensile force of pulling the film enclosed batting through the cavity or wire mesh sleeve and is subsequently driven off by high temperature baking, leaving only the insulation in the cavity or wire mesh sleeve.

A distributed cell field-effect transistor (FET) amplifier (40) includes a plurality of parallel, elongated source (46a) and drain (46b) regions of individual FET unit cells (46) formed in a substrate (42) in transverse alternating relation, with a plurality of elongated channel regions (46c) being formed between and parallel to adjacent source (46a) and drain (46b) regions respectively. A source foot (48) and a drain foot (50) extend perpendicular to the source (46a) and drain (46b) regions on opposite longitudinally spaced sides thereof respectively. A gate foot (52) extends parallel to the source (48) and drain (50) feet, between the source foot (48) and the cells (46). Source (54) and drain (56) pads and gate (58) fingers extend from the source (48), drain (50) and gate (52) feet into electrical connection with the respective source (46a), drain (46b) and gate ( 46c) regions respectively. The source pads (54) include airbridge portions (54b) which extend over the gate foot (52) without making contact therewith. A fixed tuning circuit (70) is connected between the gate foot (52) and source foot (48), including an inductive stub (72) having a first end connected to the gate foot (52) and a second end, and a capacitor (74) having a first plate (74a) which is integral with the source foot (48) and a second plate connected to the second end of the stub (72).

A transceiver is described which utilizes D-shaped optical fiber technology and advanced flip chip mounting techniques for manufacturing an integrated transceiver chip for use in electronic microcircuit applications. A single D-shaped optical fiber is used for bi-directional signal transmission, with coupling gratings superimposed on the flat surface of the fiber for coupling light into and out of the optical fiber. A light source and optical detector, aligned with the respective coupling grating for optical communication with the fiber, are flip mounted on the substrate which supports the fiber. Finally, the light source and optical detector are electrically connected with associated electronic circuitry also mounted or fabricated on the substrate.

A seal assembly can include a sealing component and a spring energizer located within a seal cavity or spring cavity of the sealing component. The sealing component provides an exterior surface for providing protection of the seal cavity and spring energizer from an external or contaminated environment, such as the atmosphere. The sealing component can have two distinct first and second sealing points. Each distinct first sealing point can have two discrete first sealing points and each second sealing point can have two discrete second sealing points. Part of the spring energizer can extend externally of the sealing component.
