Title: Field effect transistor construction
IPC: H01L23/522
Filed: 1980-03-26
Abstract: The punch-through and breakdown voltages of an FET are increased by providing shield electrode means 28, 29 which surround the conductive connections 11, 14 to the source and drain regions 10, 13. The shield electrode means lie in the insulating layer 19 over the semiconductor body 21, closer to the conductive connections and further from the surface of the semiconductor body than the gate electrode means 16. The gate 16 may be split, 16' and 16'', and the shield electrode means may be connected to or formed as part of the gate electrode means. If separate, the shield electrode means can be a single sheet surrounding both connections 11 and 14 and connected to a fixed voltage. A further increase of voltage limits results from making the connections 11 and 14 of doped polysilicon, giving a further thin, highly doped layer in each of the source and drain regions. <IMAGE>

Patent GB-2100540-A (GB)
Title: Reference voltage generators
IPC: G11C11/411
Filed: 1979-03-06
Abstract: A reference voltage generator comprises a differential amplifier with a negative feedback loop and having an input offset determining the output voltage, this offset being due to the difference in threshold voltages of two IGFETs T1, T2 resulting from the provision of differently doped semiconductor gate electrodes. The output of the amplifier is fed back to the inverting input either directly or via a potential divider and a reference voltage level (eg VSS or VDD) is connected to the non- inverting input. The output voltage is determined (relative to the reference voltage level) by the difference in threshold voltages of the input transistors this difference being substantially independent of temperature variations.   <IMAGE>

Title: Apparatus and methods for making payments electronically
Inventor: BELL DONALD ATKINSON
IPC: G07F7/10
Filed: 1982-06-17
Abstract: Where simply the giving of a number is to be used as a payment, problems arise as to how the number can be generated securely and how it can be verified. A secret key held in a store 16 of a customers token 10 is used to encrypt a number specifying goods and a payment to be made transmitted from a shopkeepers terminal 14. The number generated is decrypted for checking by the terminal 14 using a non-secret key supplied by a store 20 of the token 10 but the non-secret key together with coded numbers does not provided enough information for the secret key to be found and hence for fraudulent coding to be carried out. <IMAGE>

Title: Ventilated cigarette filter
Inventor: CANTELL ANTHONY SYDNEY
IPC: A24D3/04
Filed: 1982-07-06
Abstract: A cigarette filter ventilated via passages (56) and tipping wrap (14) perforations (16), the filter presenting initially relatively low pressure drop (54, 42) and relatively high pressure drop (40, 42) paths for the passage of smoke therethrough, the arrangement being such that in use the initial preferential passage of smoke via the low pressure drop path or paths causes progressive block thereof so that the passage of smoke via the high pressure drop path or paths and the degree of air ventilation are increased. The axially elongate filter core (2) may have passages (54) which are open at one end of the core, extend therefrom only partially towards the other end (50) of the core, and are in smoke- flow communication with the core via means (55) progressively blockable by the passage of unfiltered tobacco smoke therethrough. <IMAGE>

Title: Threshold sealing device
Inventor: PATON WILLIAM
IPC: E06B7/23
Filed: 1982-07-29
Abstract: A threshold sealing device comprises: a first element (8) held fast to the exterior face of a door (1) adjacent its bottom; a sealing element (11) hinged to the first element, projecting forwardly and biased upwardly; an operating element (9) connected to the sealing element; and an actuating member (3, 4) fixed at the threshold of the door. Closing the door brings the operating element (9) into engagement with the actuating member (3, 4) to cause the sealing element (11) to be hinged downwardly to form a seal at the threshold of the door. Preferably the sealing element (11) engages with the actuating member (3, 4) to form the seal on closing the door. Also preferably the operating element (9) itself sealingly engages with the actuating member (3, 4) when the door is closed to form an additional seal at the threshold of the door. <IMAGE>

Title: Personnel or object detection at sea
Inventor: BARNES JAMES BUTTS
IPC: G01S3/802
Filed: 1982-08-13
Abstract: A detection system comprises a transmitter 2 suspended from a person 6 in the water 7 by a line 8, and a receiver 14 suspended from a search vessel 16 by a line 18. In operation when the person 6 is in the water, the transmitter 2 is released and descends to a desired depth of from 2 to 6 metres and emits an ultrasonic signal. The receiver 14 is suspended at a similar depth to the transmitter 2, and the receiver 14 is rotated by turning the search vessel 16. When the search vessel 16 is within range of the transmitter 2 and pointing towards the transmitter 2, the receiver 14 picks up the ultrasonic signal. The receiver 14 includes a transducer and indicating means to give an indication of the strength and direction of the received signal. <IMAGE>
Patent GB-2191359-A (GB)
Title: A recursive method for identifying isotropic zones in a video image; a device for detecting movement and noise in a sequence of images
Inventor: RICHARD CHRISTIAN
IPC: G06T7/20
Filed: 1982-11-22
Abstract: The method enables zones to be defined in a television image, each zone consisting of a group of contiguous points in the image that have the same property, that of being in movement for example. The zones are numbered Z1, Z2....and each has a "state vector" whose components represent characteristics of the zone, e.g. the number of points contained in the zone. The assignment of a point to a zone is made as a function of the zone numbers of the neighbouring point which precedes it in the same line and of the neighbouring point in the preceding line. If these two neighbouring points had previously been assigned to two different zones, these two zones are deemed to be united, i.e. it is recognised that they are really one and the same zone. The device assigns a zone number to each point in movement. The points whose movement is due to noise are detected by the fact that they belong to zones of very small size.
Patent GB-2133815-A (GB)
Title: Fabric material
Inventor: TOUGH WILLIAM HAMISH
IPC: D03D15/56
Filed: 1983-01-18
Abstract: A fabric material is woven from tapes of synthetic resinous material such as polypropylene and the set of tapes 1 used as weft tapes have a pattern of slits 3 formed in them before weaving, so that there are zones 2 in each tape 1 in the set where the tape 1 is subdivided into several tapes 4 of lesser width. The woven fabric material is then stretched at a raised temperature by longitudinally stretching the warp tapes 6 and thus causing the slit tapes 1 to spread so that gaps are formed in the said zones 2 between the tapes 4 of lesser width. The woven fabric material is cooled in this stretched condition so that the final stretched woven fabric material obtained has a substantially greater area and a lesser overall thickness than the base woven fabric, i.e. the fabric before it was stretched. <IMAGE>
