Patent GB-2319932-A (GB)
Title: Signal processors
Inventor: EASTTY PETER CHARLES
IPC: H03M7/32
Filed: 1996-11-27
Abstract: A signal processor for 1-bit signals comprises a fifth order Delta-Sigma Modulator (DSM) having an input 4 for receiving a 1-bit signal and an output 5 at which a processed 1-bit signal is produced by a quantizer Q. The quantizer Q receives a p-bit signal from a series of 5 signal integration stages. Each stage comprises a first 1-bit multiplier An coupled to the input 4, a second 1-bit multiplier Cn coupled to the output 5, an adder 6n which sums the outputs of the coefficient multipliers and an integrator 7n which integrates the output of the adder 6n. A final stage comprises a coefficient multiplier An+1 and an adder 6n+1. The adder 6n+1 sums the output of the coefficient multiplier An+1 and the output of the integrator of the preceding integration stage. The coefficients An and Cn are chosen to provide an overall attenuation of the input signal and of the quantization noise produced by the quantizer and also to provide a low pass filter which provides a compensating gain to the input signal. In this way the quantization noise outside the band of the input signal is reduced. Reduction of quantization noise enhances stability of the circuit and also allows several DSMs to be connected in series by preventing the build-up of excess noise which may compromise stability.

Abstract: 969, 047. Moving coil instruments. S. SMITH & SONS (ENGLAND) Ltd. Nov. 1, 1962 [NOV. 1, 1961], No. 3915/61. Heading G1Q. In a moving coil electrical device of the kind in which the coil moves in a gap between a core of circular cross-section and an outer surrounding part, both parts being of magnetic material, the coil is pivotally mounted on an element which is shaped so as to interengage with the core and locate the pivot mountings at opposite ends of the core, the interengagement being effected by relative movement between the element and the core with respect to an axis passing through the centres of the circular cross-sections of the core. Such a device may be a measuring instrument with a central magnetised core 10, magnetised as shown in Fig. 6, a coil 30 and an outer yoke 12. The core contains a mild steel insert 16 and the inner and outer parts are held together by means of plastic wedges 13. The pivots 31 for mounting the coil are held in bosses 36 cemented to the coil and retained in jewelled bearings 23, 25. One of these fits in a cup 22 which is pushed into a slot 20 in the insert 16 whilst the other fits in a slot in a screw 24 which screws into a threaded part 21 of the insert. Collets 32 frictionally grip the pivot pins and are secured to hair springs 33, the other ends of which are attached to pegs 34 and 35. These may be adjusted for correcting the zero reading of the instrument and for altering the galvanometer sensitivity. The arrangement is such that the moving parts of the instrument may be assembled and adjusted before the magnetic elements are brought into position. Other embodiments are described (Figs. 1-4, not shown) wherein the configuration of the element 16 differs, where the wedging arrangements are different, and wherein the springs 33 may be adapted to be used in supplying the current to be measured to the coil.

Title: Mechanical set anchor
Inventor: HEBERT JOSEPH V
IPC: E21B23/01
Filed: 1997-01-31
Abstract: A mechanical set anchor, e.g. for a whipstock, has a plunger 60 extending from a base end 36 of an anchor body 21 which, when moved upwardly into the body 21, activates a pin type trigger 47 which releases a spring 49 utilized to set multiple slips 22 extending from the body of the anchor. Continued downward compressive forces fully sets the slips 22 into the borehole pipe casing 7. The slips 22 are maintained in their fully set position by a locking nut 55. The anchor is mechanically released by an upward pull under tension of sufficient strength to shear release pins 70 that release the compressed spring 49, fully retracting the slips 22 within the anchor body 21 so that the anchor may be tripped from the borehole without interference from the previously engaged slips.

Title: Method for forming shallow junction of a semiconductor device
Inventor: LEE KIL HO
IPC: H01L21/8234
Filed: 1997-06-06
Abstract: To form a semiconductor device having a shallow junction region, ion-implanted regions are formed by ion implantation through an insulating layer, and, after removal of the insulating layer, a rapid thermal anneal is carried out for a short time, e.g. at 750-1050{ C for 2-60 Sec. Insulating and planarising layers 38 and 39 are then formed, and the device is then subjected to a tube thermal treatment, e.g. at 750-900{C for 10-90 min, to change the ion-implanted regions into shallow source/drain regions 40A, 40B. The rapid thermal anneal removes point defects and vacancies which would otherwise cause the diffusion of dopant during the tube thermal treatment, and so results in a shallower junction, a lower sheet resistance and lower leakage current of the device. Processes are described for implanting arsenic, boron fluoride and boron ions.

Title: Method of Tracking Dynamic Communication Parameters during a Link Interruption
Inventor: ANDRESEN MICHAEL J
IPC: H04B7/185
Filed: 1997-09-15
Abstract: In a mobile communication system (90) wherein communication parameters vary appreciably between transmissions, subscriber units (200) are susceptible to link blockages resulting in a loss of successive feedback instructing subscriber units (200) of adjustments to communication parameters to be employed in a subsequent transmission on a communication link (105). When a mobile subscriber unit (200) is airborne, an outage may occur from a control surface blockage during maneuvering. Aircraft avionics (290) supplies acceleration data representing aircraft movement for use in predicting subsequent communication parameters. These predicted parameters are employed in re-establishing communications upon the removal of such a link blockage.

Title: Plug in commutator with deformable segments
Inventor: EDGERTON DOUGLAS ARTHUR
IPC: H01R39/04
Filed: 1997-09-29
Abstract: A plug in commutator comprises commutator segments 2 with swallow tail portions 11 which render them resiliently deformable. The segments may be slotted into graves 5 formed on a hub body 1 so that the swallow tail portions form an interference fit with the interior of the grooves. As the portions are resiliently deformable, the stresses imposed on the hub body and segments during insertion of the segments and normal use of the commutator are relieved. The segments and grooves may be of constant cross section throughout their length. The grooves are formed by ribs 4 of substantially circular cross section, which helps to uniformly distribute the stress imposed on them by the segments. The end of each segment may include a tongue part 7 which may be bent to form a hook 7', to allow the connection of wires.

Title: Moisture sensing probe
Inventor: DADACHANJI FALI MINOCHER
IPC: G01N27/04
Filed: 1998-02-20
Abstract: A probe 2 for use in sensing moisture content of bulk grain or other granular material comprises a cylindrical tube, for example of plastics, having a tapering nose, and having adjacent said nose first and second electrical conductors 10, 12 wound helically around the tube so that the turns of one conductor are spaced from, and alternate with, the turns of the other conductor.

The conductors extend through respective apertures in the plastics tube and are connected within the tube to respective insulated conductors extending to electronic measuring circuitry within a handle 4 of the probe. Arranging the conductors on the lateral surface of the probe instead of using protruding electrodes facilitates the ready insertion of the probe into bulk material.
