Title: Graded layers in an optoelectronic semiconductor device
Inventor: DUGGAN GEOFFREY
IPC: H01S5/00
Filed: 1997-07-10
Abstract: A LED or Laser Diode comprises a sapphire substrate 1, a GaN buffer layer 2, an n-doped GaN contact layer 3, an n-doped (AlGa)N cladding layer 4, a Zn-doped (InGa)N active layer 5, a p-doped (AlGa)N cladding layer 6 and a p-doped GaN contact layer 7. Grade layers 41, 42, 43 and 44 are introduced at the interfaces between cladding layers 4 and 6 and both the contact layers 3 and 7 and the active layer 5. The constituency of each graded layer monotonically varies through the layer such that the graded layer is lattice matched with the adjacent layer on each side to reduce the interface strain between layers. Figure 7 depicts only the position of the graded layers and not the position dependence of the energy gap through the graded region.

Title: Mounting contacts in connector
Inventor: YANG GEORGE
IPC: H01R13/502
Filed: 1997-12-31
Abstract: Disclosed is a two-piece connector including a plastic body 3 and a top plate 4. The plastic body is formed of alternately arranged upper and lower pin holes for a plurality of pins to insert into. The upper and the lower pin holes are separated from one another by a separating wall 33 between them. The top plate can be covered and connected to the plastic body by engaging two mortises 41 on the top plate with two tenons 34 on the plastic body. A portion of the top plate extends beyond the plastic body after the top plate is connected to the plastic body. A plurality of ribs 42 are provided on a bottom surface of the portion of the top plate extending beyond the plastic body. Each clearance between two adjacent ribs forms a pin hole 43 corresponding to one of the upper pin holes 31 on the plastic body and forming a continuation of the upper pin hole. Pins can be more easily and accurately inserted into the upper pin holes before the top plate is covered to the plastic body to enhance the production efficiency.

Title: Network analyser measurement method
Inventor: DUNSMORE JOEL P
IPC: G01R27/06
Filed: 1998-10-16
Abstract: A measurement method for a network analyser 20 comprises adjusting the bandwidth of at least one IF filter F1-F4 to a first predetermined range for measuring the forward transmission and/or reflection parameters of a device under test DUT. Adjusting the bandwidth of at least one IF filter F1-F4 to a second predetermined range for measuring the reverse transmission and/or reflection parameters of the device under test DUT. Then using at least one of the above measured parameters to derive at least one of the coefficient values relating to the device under test DUT. Certain parameter measurements may be taken using filters having a narrow bandwidth to provide a slow accurate measurement whilst certain other measurements may be taken using filters with a broad bandwidth to provide a less accurate but faster measurement. Measurements may be made using frequency range sweeps or a stepped single-frequency. The measurement method may provide fast measurements for high dynamic range devices whilst maintaining reasonable accuracy.

Title: Barrier coating of barium strontium aluminosilicate for silicon-based materials
Inventor: SPITSBERG IRENE THEODOR
IPC: C23C28/04
Filed: 1999-01-14
Abstract: A coating system 14 for a substrate 12 containing a silicon-based material, such as silicon carbide-containing ceramic matrix materials containing silicon carbide and used to form articles 10 exposed to high temperatures, including the hostile thermal environment of a gas turbine engine includes a layer of barium strontium aluminosilicate (BSAS) as a bond coat 16 for a thermal-insulating top coat 18. As a bond coat 16, the BSAS layer serves to adhere the top coat 18 to a SiC-containing substrate 12. The BSAS bond coat 16 exhibits sufficient environmental resistance such that, if the top coat 18 should spall, the BSAS bond coat 16 continues to provide a level of environmental protection to the underlying SiC-containing substrate 12.

Title: Gas turbine engine including first stage driven by fuel rich exhaust gas
Inventor: PETERSENIOR
IPC: F02C6/00
Filed: 1999-02-01
Abstract: A gas turbine engine comprises a first combustor 16, which burns a rich mixture of fuel and air at high pressure to produce a first stage exhaust containing partially combusted fuel. The first stage exhaust drives a first turbine 22 and is then introduced to a second combustor 28, in which combustion is completed in a slightly lean mixture with air. A second stage exhaust from the second combustor 28 drives a second turbine 34. The engine is stated to be highly efficient and low in emissions. It is suitable for single-shaft 50 or twin-shaft (50,52 fig 2) configurations. Engine power may be controlled by varying the proportion of air supplied to the first and second combustors 16,28 from a compressor 10. A closed circuit cooling system may supply cooling air (26,38 fig 1) to the turbines 22,34.

Title: Video wipe generator for random wipe effect
Inventor: GREENWOOD JONATHAN MARK
IPC: H04N5/275
Filed: 1999-04-09
Abstract: A signal generator for use in a video wipe generator for generating a wipe 'solid'. The signal generator generates a solid which comprises an array of tiles having random amplitudes. The horizontal and vertical dimensions of the tiles are variable and may be randomly variable. The dimensions may be one pixel. The horizontal and vertical dimensions are defined by Hsize (10, fig.5) and Vsize (12) generators which define the boundaries of the tiles. The generators (10) and (12) include pseudo random number generators (PRB3 and 4) for randomising the dimensions. They control another pseudo random number generator (14) which defines the random amplitudes (PRB1) of the tiles. The tiles may flicker at an adjustable rate defined by the comparison (20) of a flicker rate (FR) control signal and a pseudo random number (PRB2) produced by another pseudo random number generator (18).

Title: Vertical cavity surface emitting laser with monitoring diode
Inventor: WICKSTROEM MIKAEL
IPC: H01S5/183
Filed: 1999-05-05
Abstract: A vertical cavity surface emitting laser (VCSEL) and monitoring diode combination has reduced parasitic capacitance for use in high bandwidth communications systems. The VCSEL 20 has both p-type and n-type contacts 24,26 on the same face. This allows the VCSEL to be mounted on the photo-detecting surface of a monitor chip or diode 10 without using a metal contact layer. In an embodiment wherein the VCSEL is soldered to the monitor chip for mechanical stability only a small metal pad no larger than the VCSEL is used. The reduction in metallisation results in a lower parasitic capacitance that in turn results in higher potential operational speeds. The VCSEL and diode are mounted in a package having a window or lens with a partially reflective surface such that some light emitted by the VCSEL is reflected back to the monitoring diode. The VCSEL may be top or bottom emitting.

Patent GB-191111999-A (GB)
IPC: H04B1/48
Abstract: 11,999. Girardeau, E. May 28, 1910, [Convention date]. Wireless telegraphy.-In a combined transmitting and receiving system in which a small gap C in the aerial circuit is bridged by the transmitting-current but not by the received waves which pass through the jigger J to the detector D, the voltage across the gap C is reduced during sending by allowing ultraviolet light from the main spark-gap E, or from a neon tube shunting part of the oscillation-circuit P, to fall upon the gap C. This allows the use of a more sensitive detector.

Filed: 1984-10-30
Abstract: The invention provides a novel process for the manufacture of [2,3-trans]-tetrahydro-5-hydroxy-3-hydroxymethyl-2-phenylfurans of the formula IIa, useful as intermediates in the production of novel (4-phenyl-1,3-dioxan-cis-5-yl)alkenoic acids of the formula I in which Ra and Rb are independently hydrogen, alkenyl, alkyl, halogenoalkyl, pentafluorophenyl, aryl or aryl-(1-4C)alkyl; or Ra and Rb together are polymethylene; Rc is hydroxy or (1-6C)alkanesulphonamido, A is vinylene, n is 1, Y is polymethylene, and benzene ring B bears various optional substituents. The compounds of formula I are obtained by the reaction of an aldehyde of formula II with an ylid to give an erythro-diol of formula III which is then cyclised to the required dioxane derivative of formula I. The aldehydes of formula II are obtained from the corresponding lactols of formula IIa, which are themselves obtained with the correct trans-stereochemistry by the inventive process using two selective reductions of a trans-phenylparaconic acid of formula V. The compounds of formula I are useful as therapeutic agents.
