Patent GB-2235335-A (GB)
Title: Capacitors for dram cells
Inventor: LEE YOUNG JONG
IPC: H01L27/10
Filed: 1990-08-03
Abstract: A process for fabricating trench capacitors of a DRAM includes the formation of an oxide film over the trench walls and the subsequent deposition of a silicon layer into the trench by a CVD process. Side spacers 4a are then defined in the bottom of the trench by anisotropic dry etch of the silicon and wet etch of the oxide film where it is not protected by the silicon. The substrate at the bottom of the trenches is subjected to ion implantation 5a with a dopant having an opposite conductivity type to that of the impurity diffusion area of the associated transistor. The oxide layer 3a covered by the spacers prevents leakage currents through the side walls, the doping of the trench bottoms reduces leakage there, and the spacers provide a smoother shape to the trench bottom which avoids electrical weakspots in the dielectric layers 6 of the capacitors 5-7. <IMAGE>

Patent GB-2253979-A (GB)
Title: Graphics accelerator line drawing using parallel processed pixel patches
Inventor: NEAVE JOHN WALTER
IPC: G06T17/00
Filed: 1991-01-09
Abstract: A graphics accelerator system which provides improved image rendering speed. One of the key bottlenecks in such systems is the step of "line drawing," or translating the mathematical description of a line into an actual image (i.e. a set of color and/or intensity values for each of a predetermined field of pixels). Another key bottleneck is the step of "line tracking," to find where a line intersects with another line (or other object). The disclosed system provides improved rendering speed, by performing line drawing and tracking with reference to patches of pixels, and processing all pixels of each patch in parallel. The patches are preferably aligned in one direction, but not in the other. That is, when it is necessary to choose a new patch of pixels, the new patch of nxn pixels will have a left edge which coincides with the right edge of the old patch; but the bottom edge of the new patch may displaced from that of the old patch by -1, 0, 1, 2, or more pixels in the vertical direction. The amount of displacement of the new patch in the vertical direction is selected so that the line being tracked will strike one SPECIFIC line segment in the new patch. <IMAGE>

Title: A vent arrangement for a fuel tank
Inventor: BOWLES DAVID THOMAS
IPC: B60K15/035
Filed: 1991-04-19
Abstract: A fuel tank 10 has a vent passage 18 through which fuel vapour can be vented from the tank. In order to close this vent passage during refuelling, a float valve 28 is arranged below the vent and inside a housing 24 with a skirt 32. When the fuel level rises to the maximum design level, fuel can still rise inside the skirt until the float shuts off the vent passage. A secondary valve 36 is movable to control flow between the inside and outside of the housing. Means such as a spring-biassed diaphragm 40 are provided to control the secondary valve 36. As described, valve 36 is closed during refilling soon after the float valve 28 closes, but is opened again when the filter cap is replaced and the fuel has been shaken up by movement of the tank. However if the tank orientation changes eg. due to a vehicle overturning, the spring moves so that the vent passage 18 is reclosed. <IMAGE>

Patent GB-918589-A (GB)
IPC: F02D9/00
Abstract: 918,589. Fluid-pressure servomotor control systems. CURTISS-WRIGHT CORPORATION. Feb. 23, 1960 [Feb. 24, 1959], No. 6367/60. Class 135. [Also in Groups XXVI and XXXI] The speed of a vehicle is governed by a throttle valve T, Fig. 1, actuated by a spring- loaded diaphragm 33 supplied with suction through pipes 21, 23, 36 from the engine intake manifold M downstream of the throttle valve T under the control of a pilot valve 2 moved by a diaphragm 13 subjected to pressure in a,pipe 11, the pressure in which is generated by a pump 1 (see also Group XXVI) varying in response to change of vehicle or engine speed. The shuttle-lift pilot-valve closure 25, which is disposed in a chamber 22 that leads via the pipe 36 to the diaphragm 33, controls the degree of communication between chamber 22 and both a chamber 20, into which pipe 21 opens, and the interior of the pilot-valve casing 16 which is open to atmosphere through a filter 19. The fluid acting on diaphragm 13 is opposed by an adjustable speeder-spring 32 whilst the closure 25 is solely supported on leaf springs 30, 31 to ensure its friction free movement. To compensate for variations in suction the closure 25 is provided with a disc 14 disposed in but spaced from an orifice 15 between the chamber 20 and the interior of the easing 16, the disc 14 being large enough to ensure positive speed droop. Overriding control of the throttle valve T from the accelerator pedal 5A is obtained through a linkage A<SP>1</SP>. To ensure that chamber 22 is never completely cut off from the interior of the casing 16, a small adjustable by-pass or a stop limiting the downward movement of the leaf spring 30 is provided. The pilot-valve closure is made of two parts and its assembly and fitting is described. Pipe 21 is either connected to atmosphere or pipe 23 by a solenoid-actuated closure 44 having a holding coil, the circuit being taken over the ignition switch 46, a switch 47 that is closed when the transmission control mechanism, not shown, is set for normal driving, a switch 49 opened when the brake pedal B is slightly depressed, an optional switch 48 that opens as a function of a rise in brake fluid pressure, and a normally open governor energizing switch 50. The pilot-valve closure 25 actuates an adjustable switch 55 controlling a warning light or flasher 56 which indicates when the set governed speed has been exceeded during manual control of the vehicle. The warning light may be replaced by a vibrator connected to the accelerator pedal or some part of the linkage A<SP>1</SP> whereby the warning is imparted by " feel " to the driver alone; this vibration may be applied by an electric or suction actuated motor. Specifications 826,373 and 826,374 are referred to.
