Title: Radiation absorber comprising a CVD diamond film having special surface characteristics
Inventor: SUSSMAN RICARDO SIMON
IPC: G01J5/08
Filed: 1992-02-21
Abstract: A radiation absorber comprising a CVD diamond film (16) (24) having at least one of the following characteristics:   (a) a surface (18) adapted to be exposed to the radiation and having a roughened or patterned profile so as to trap incident radiation by multiple reflections; (b) a surface (26), bulk texture and grain size such that it is highly absorbent to the radiation by virtue of internal scatterings and multiple reflections.   In (a) the diamond film will replicate the surface of the substrate on which it is deposited. The substrate may thereafter be removed, for example, by chemical etching. The substrate may be silicon, silicon nitride, tungsten carbide, sialon, silicon carbide, a diamond compact, molybdenum, copper, titanium, or tungsten. <IMAGE>

Patent GB-2265960-A (GB)
Title: Explosive punching device
Inventor: BARKER MICHAEL ALEXANDER
IPC: F16L55/10
Filed: 1992-04-02
Abstract: The device comprises a wedge shaped stack of steel plates, a semi-cylindrical steel bit (6) and an explosive charge (8). Detonation of the charge (8) causes the device to be explosively projected towards a target with high momentum and high speed compared to non-explosive devices, however the shock wave initiated by the detonation of the explosive material is attenuated by repeated reflections at each plate interface, so that fragmentation of the device and target are avoided. By mounting a device on each side of a fluid filled pipe to be sealed, such that they are in direct alignment, the pipe may be sealed by a pincer effect when the devices are simultaneously fired towards the pipe. <IMAGE>

Title: Bicmos process utilizing novel planarization technique
Inventor: MATTHEWS JAMES A
IPC: H01L29/417
Filed: 1992-06-25
Abstract: A method for forming a BICMOS integrated circuit having MOS field effect transistors and bipolar junction transistors is disclosed. The process comprises first defining separate active areas, forming a gate dielectric layer and a first layer of polysilicon. This polysilicon is then selectively etched to form a plurality of equally-spaced first polysilicon members comprising the gates (33, 34) of the MOS transistors and the extrinsic base contacts (35) of the NPN transistors. After insulating the first polysilicon members, an additional layer of polysilicon is deposited over the substrate to replanarize the entire wafer surface. The additional layer of polysilicon is then etched to form a plurality of second polysilicon members (65, 66, 67, 68, 69). Impurities are diffused from the polysilicon members to form source/drain regions (73, 74, 75, 76) of the MOS transistors and the extrinsic base (81) and emitter (77) regions of the NPN transistors. The final processing steps include providing the interconnection of the MOS and NPN transistors. <IMAGE>

Title: Electro-optic modulator
Inventor: EPWORTH RICHARD EDWARD
IPC: H04B10/2507
Filed: 1992-12-23
Abstract: An electro-optic modulator (10) has its capacitance incorporated in the resonant circuit of an RF oscillator.

Alternatively the modulator may be supplied with a digitally modulated optical soliton pulse train and the frequency and phase of the RF oscillator locked to that of the clock component of that pulse train to provide retiming and reshaping of its solitons. The RF oscillator may be voltage-controlled. The invention reduces the drive voltage requirements of the RF oscillator. <IMAGE>

Title: Iterative subset pattern derived topography processor
Inventor: DOWNS ROGER COLSTON
IPC: G01S17/89
Filed: 1993-11-18
Abstract: An iterative subset pattern derived topography processor utilises two image sensors of defined separation and orientation whose fields of view share a common scenario. The luminance signal derived from both image sensors defines sets of subset patterns of image elements and their position within each image sensors field of view. For subset patterns identified from both image sensors, the system iteratively synthesises combinations of such subset patterns between image sensors to establish a correlation between members of such combinations of subset patterns. A multiple correlation condition is employed to reduce anomalous comparisons, whereby for such correlation of subset pattern information between image sensors, the azimuth and elevation position of such unique pairs of subset pattern members within their respective image sensor fields of view fix the relative spacial position of their associated topographical detail. <IMAGE>

IPC: H04N11/18
Filed: 1994-09-23
Abstract: In a SECAM television system, errors in determining a phase angle in the demodulation of colour difference signals U and V are reduced by first identifying the quadrant or sector containing the signal and then transforming U and V values into a region of minimum quantisation error. Quantisation errors arise due to the digital nature (look-up tables) of determining the phase angle  theta  (= arctan v DIVIDED u). <IMAGE>

Title: Noise reduction apparatus
Inventor: NAKAJIMA YASUYUKI
IPC: H04N19/154
Filed: 1995-02-02
Abstract: In picture decoding from compressed data, a noise component is predicted for each pixel and noise-free original picture data is derived from the predicted noise component and the decoded picture data. An activity calculation circuit (11) derives the horizontal activity (i.e. variation in luminance magnitude) of block-based decoded picture data, and a block mean noise prediction circuit (12) predicts black mean noise according to the activity obtained in the activity calculation circuit (11) and a block quantisation step. A pixel noise prediction circuit (13) derives predicted noise in each pixel from the predicted block mean noise obtained in the block mean noise prediction circuit (12) and the activity obtained in the activity calculation circuit. A filter coefficient determining circuit (14) determines filter coefficients and a filter circuit (15) predicts and outputs noise-free picture data. The horizontal noise reduction circuit (21) is followed by a vertical noise reduction circuit 22, although their order is not critical. <IMAGE>
