Title: Interdigital source and drain islands mesfet (isdi-fet)
Inventor: DINDO SALAM F
IPC: H01L29/812
Filed: 1992-06-02
Abstract: ABSTRACT        A microwave semiconductor device with a FET structure having Interdigital Source and Drain Islands (ISDI-FET) has active layers separately defined for each source-gate finger-drain subcell so that each FET cell is divided into islands.  The device includes pairs of FET subcells with collinear source and drain electrodes, separated by narrow gate fingers, formed on a GaAs substrate.  Each gate finger is connected via a gate lead and a metal strap to a gate electrode contact pad, the metal strap having air bridges which extend over source electrodes on source regions of other pairs.  A U-shaped metal strip connects a drain pad to drain electrodes at contact areas on the legs of the U-shaped strip, those legs extending over source electrodes and gate fingers via air bridges.  The source electrodes on one side of pairs of FETs are connected to a first source electrode wiring layer via a metal strap that forms air bridges over drain electrodes while source electrodes on the other side of a pair are connected to a second source electrode wiring layer via another metal strap that forms air bridges over drain electrodes.          This arrangement offers the low noise advantage of PI-FETs and some of the real estate savings of standard interdigital FETs.          It also provides an arrangement in which large numbers of pairs of FETs can be interconnected together to form a power device.

Title: Optical interferometric gyro having reduced light to the light source
Inventor: ASAMI EIICHI
IPC: G01C19/72
Filed: 1991-08-29
Abstract: The present invention relates to an optical interferometric gyro having reduced return light to the light source.  The gyro is configured such that light from a light source is split by a first optical coupler into two light beams.  One of the light beams is further split by a second optical coupler into two beams.  One of the second mentioned light beams is provided as a clockwise light beam to one end of a looped optical transmission line, and the other light beam is provided as a counterclockwise light beam to the other end of the looped optical transmission line.  The clockwise and counterclockwise light beams after having been passed through the looped optical transmission line are combined by the second optical coupler to interfere with each other.  The interference light is branched by the firs optical coupler to the light source and a photodetector, and an angular velocity applied to the looped optical transmission line about its axis is detected from the output of the photodetector.  The branching ratio of the first optical coupler is selected such that the quantity of light to be branched to the photodetector is larger than the quantity of light to be branched to the light source.

Title: Filter assembly with a spin welded end cap
Inventor: REED CLAYTON L
IPC: B01D29/07
Filed: 1992-06-26
Abstract: ABSTRACT OF THE DISCLOSURE   The filter assembly includes a filter element having an end surface and an end cap connected to the end surface by spin welding. The end cap has an outer diameter that need be no larger than the outer diameter of the end surface of the filter element. Prior to spin welding, the end cap may have a surface with a sacrificial ridge extending from the surface. The end cap is spin welded to the end surface of the filter element by rotating the filter element and the end cap with respect to one another while contacting the sacrificial ridge with the end surface of the filter element, melting the sacrificial ridge by the contact with the filter element to form a molten plastic, and joining the surface of the end cap to the end surface of the filter element with the molten plastic. Also disclosed is a method of spin welding a filter pack to an end cap without a sacrificial ridge.

Title: Methods for manufacturing composite surface elements
Inventor: MITCHELL JOHN J
IPC: E04F13/14
Filed: 1990-12-28
Abstract: A method of manufacturing a stone-faced composite surface element in which a resin-impregnated fibrous matting (5) is applied to each of the two opposite faces of a stone slab (1) while the resin is in an uncured state. A backing layer (6) is applied to each of the exposed surfaces (3, 4) of the fibrous matting (5). The resin is cured to bond each backing layer (6) to the stone surface through the intermediary of the fibrous matting (5). The stone slab is sawn in two along a cutting plane (9) substantially parallel to, and midway between, the two opposed surfaces (3, 4) of the stone slab (1) to leave a thin lamina of stone attached to each backing layer. The backing layers (6) may be constructed in situ by applying to each exposed surfaces (3, 4) of the fibrous matting (5), after they have been attached to the stone slab (1), a layer of a light weight multicellular material (7), and then applying to the outer surface of the multicellular layer an outer skin of material (8).

Title: Optical source with frequency locked to an in-fiber grating resonator
Inventor: HUBER DAVID R
IPC: H01S3/00
Filed: 1992-10-05
Abstract: A frequency stabilized optical signal source is provided. A laser produces an optical carrier at a wavelength ~. Feedback is provided to adjust the wavelength ~. In order to provide the feedback, a portion of the optical carrier is modulated by a periodic reference signal. An optical fiber with an in-fiber resonator is coupled to receive the modulated optical carrier. The resonator effects a phase and/or amplitude change between the modulated optical carrier and a sideband thereof at a resonant frequency of the resonator. The phase or amplitude change is detected and used to adjust the laser wavelength. In a preferred embodiment, a moire grating having a single resonant frequency is used as the in-fiber resonator. The feedback scheme can lock either to the carrier frequency itself, or to a selected sideband of the modulated optical carrier.

IPC: H04B14/04
Filed: 1992-03-20
Abstract: An audio signal has its dynamic range compressed by a system which first samples a block of the audio signal (10), typically several seconds long. The level of the signal in this block is analysed (12, 14) and an ideal signal level is calculated for the block (16, 18, 20). A gain control signal is then derived which adjusts the gain applied to that block towards that required to give the calculated ideal signal level.
