Patent GB-2243313-A (GB)
Title: Apparatus for applying films to substrates
Inventor: HEBELS ALBERT
IPC: B05C1/08
Filed: 1991-04-24
Abstract: An apparatus for applying a film of adhesive coating material to one side of a running substrate has a first drum-shaped conveyor (1) which transports the substrate (3), and a second drum-shaped conveyor (7) which transports a relatively thick layer of adhesive material (9). The two conveyors are sufficiently close to each other to ensure that the layer contacts the exposed side of the substrate and the nip immediately downstream of the locus of minimum distance of the two conveyors from each other contains a splitting tool (17) which extends into the coating material to separate from the layer a film (14) which adheres to the exposed side of the substrate. The major portion of the layer (18) remains on the second conveyor. The splitting tool can include a length of thin wire or an elongated nozzle which discharges a long jet of compressed inert gas into the nip so that the jet severs or shaves the film off the layer of coating material. <IMAGE>

Title: Process for reducing program disturbance in EEPROM arrays
Inventor: TZENG JYH-CHERNG J
IPC: H01L29/49
Filed: 1991-06-21
Abstract: An EEPROM memory cell incorporates a floating gate 33 disposed above and insulated from a channel region by a gate oxide 30, 31 the gate oxide having a first thickness 31 over a portion of the channel near a drain region 37, and a second reduced thickness 30 over a different portion of the channel near a source region 36; and a control gate 35 disposed above and insulated from said floating gate; wherein the drain region 37 is sharply defined and shallow compared to the source region 36. The floating gate is charged from the channel region by injection of hot electrons from the channel near the drain region, and the floating gate is discharged by removal of electrons from said floating gate into the substrate through Fowler- Nordheim tunnelling of electrons through the gate oxide near the source regions. The gate oxide may be selectively thickened by intentional damage (28. Fig. 4) caused to enhance subsequent oxidation, alternatively oxide (41, Fig. 7) is formed near the drain and then the structure is oxidized to produce oxide layer 30, 31. Disturbance in adjacent cells of an array of cells is reduced while speeding up erase performance. <IMAGE>

Title: Reinforced composite structural members
Inventor: HEAD PETER RICHARD
IPC: B29C70/06
Filed: 1992-05-01
Abstract: Composite structural members moulded or pultruded from plastics or ceramic material and containing fibre reinforcement configured such that in flange portions of the member reinforcing fibres lie predominantly at angles of 0 DEG  to 90 DEG  to an axis of the member whereas in web portions the reinforcing members lie predominantly in directions oppositely inclined to the axis, each at an angle in the range 30 DEG  to 80 DEG . Reinforcing fibres are made up by, for example, knitting, braiding or weaving, into a preform having the desired fibre configuration, the preform being laid in a mould, pulled through a die or otherwise introduced during manufacture in any convenient manner. Highly accurate fibre placement is possible yielding greatly improved strength as compared with conventional techniques, at joints between web and flange portions of the member.

Title: Fluidic circulation device.
Inventor: HAYWOOD KENNETH HERBERT
IPC: B01D17/02
Filed: 1993-10-01
Abstract: A fluidic circulation device has a chamber containing a fluid flow device in the form of a Coanda nozzle (B). Primary fluid is supplied to the Coanda nozzle B through an inlet (A) to create fluid circulation in the chamber before discharging through an outlet (C). Thus fluid emerging from the nozzle (B) flows round the outside of an attachment surface entraining surrounding fluid present in the chamber to produce circulation round a path (K-E-F-D) including a non-return flap valve (D). The path also includes a processing zone such as a tube heat exchanger (H) having an inlet (G) and an outlet (J) for coolant. Alternatively the processing zone may be a gas scrubber Fig. 3 (not shown), a flare/combustor/incinerator, a filtration system, a catalytic reactor, mass transfer hardware, or a mixer.

Title: Motion analysis of moving images
Inventor: WALTERS CARL WILLIAM
IPC: H04N7/00
Filed: 1992-03-24
Abstract: Motion vectors are derived by means of a correlation surface. The correlation maximum M1 from within a group of equally valid correlation maxima within the composite correlation surface that has the lowest magnitude displacement vector V1 is used to determine the motion vector for that correlation surface. A search pattern through the correlation surface having a monotonically increasing displacement vector magnitude is described. Once motion vectors have been identified for all of the blocks making up the image, a small group of motion vectors is picked for each block in a vector reduction step prior to further processing. The search for motion vectors for inclusion in this group uses a predetermined selection test and takes place in a primary set of blocks abutting the target block in question and then in a secondary set of blocks surrounding the target block but spaced from the primary set blocks. <IMAGE>

Title: Method for fabricating capacitors for a semiconductor device
Inventor: PARK YOUNG JIN
IPC: H01L27/108
Filed: 1996-02-27
Abstract: Capacitors with storage electrodes provided with irregular side walls of increased surface area, and for use as DRAMs, are formed by an etching process using the difference in etch selectivity between doped and undoped silicon films. In the method, doped and undoped amorphous conduction films (17, 19) are formed alternately over a semiconductor substrate (11) having a contact hole (15, Figure 1) to form a first amorphous conduction layer having a multi-layer structure, then an insulating film pattern (21') is formed on the amorphous layer (17, 19), and then undoped and doped films (25, 27) in an alternating manner, thereby forming a second amorphous conduction layer. The structure is then etched, using the insulating film pattern (21') and a lower insulating layer (13) as etch barriers. The amorphous layers are then annealed to form crystallized conduction layers without diffusing an impurity. Doped portions of the conduction layers are then etched to provide the irregular structure. Impurity ions are doped into undoped portions of the conduction layers, thereby forming a cylindrical storage electrode (29, Figure 8).

Title: Beverage can with foam generating capsule
Inventor: REYNOLDS ANDREW JOHN
IPC: B65D85/73
Filed: 1994-09-28
Abstract: A sealed beverage can has fitted therein a capsule (10) forming a secondary chamber within the can, the capsule having an associated standpipe (12) apertured at (14) beneath the capsule and terminating at its upper end (16) just below a deformable roof (18) of the capsule, thereby to form an openable and closable valve at the upper end of the tube, whereby communication between the interior of the capsule and the contents of the can is restricted until at least after the can is inverted during pasturisation, whereafter pressurised gas in the gas headspace is able to enter the capsule through the said aperture after the said valve has opened. The restrictor may comprise a controlled leak across the valve which permits the slow ingress of fluid into the capsule. Alternatively at least part of the wall of the capsule is formed from gas permeable material, the permeability of which is such as to restrict the ingress of gas for a sufficient length of time as to prevent a balancing of the pressures to occur until at least after pasturisation has begun.
