Patent GB-2280922-A (GB)
Title: Reflecting road stud
Inventor: BARKER JOHN EDWARD
IPC: E01F9/06
Filed: 1994-08-10
Abstract: A reflecting road stud comprises a base unit having a circular spigot 10 for mounting in a circular hole in the road surface and a generally rectangular protector 12. The protector 12 extends beyond the spigot 10 to the front and rear of the stud to form flanges 14, 16 which rest on the road surface. A socket 22 is formed in the protector 12 and the spigot 10 for receiving a reflector mounting. The upper surfaces of the flanges are tapered to form ramps 28 and openings in the ramps 28 allow light access to the reflectors. The base unit may be formed from a plastics material such as filled nylon. <IMAGE>

Title: Motorised personal transport vehicle
Inventor: FIELDS CHRISTOPHER ROY
IPC: B62K5/025
Filed: 1994-09-27
Abstract: The vehicle transports a person sitting or standing for many miles and is usable in all pedestrian areas. It will climb a 1:4 gradient and can tow a trailer. The multi-directional drive/steering unit 11/12 is rotatable through 360 DEG  giving immediate motion in any horizontal direction. A stabilising system, which may comprise a pivot 14 with fore-and-aft axis to enable the handlebars to lean, greatly reduces the likelihood of the rider and vehicle becoming unstable while traversing lateral slopes. The vehicle has simple fold-away features with no separation of parts and is light enough to be carried upstairs, lifted into a car, bus or aircraft or pulled along on its rear wheels. It can be stood on-end for space saving. The self-contained drive/steering unit can be attached, via a simple bracket, to other lightweight unpowered mobile devices to give similar powered and steering features or be a powered unicycle. These general features can be packaged in several forms. <IMAGE>

Title: Field effect transistor
Inventor: KOHNO YASUTAKA
IPC: H01L29/08
Filed: 1993-08-04
Abstract: In a field effect transistor including a Schottky gate electrode (3) disposed on an active region (2) formed in a compound semiconductor substrate (1), a compressive stress of the gate electrode and a tensile stress of an insulating film (8) serving as a passivation are concentrated on the lower end part of the gate electrode (3), whereby positive piezoelectric charges are produced in the compound semiconductor substrate (1) in the vicinity of the gate electrode (3). The positive piezoelectric charges increase the effective donor concentration, reducing the thickness of the surface depletion layer. As the result, the channel narrowing due to the surface depletion layer is suppressed. A high impurity region (50) gets progressively nearer to the gate electrode (3) with depth in the substrate 1. <IMAGE>

Title: Scanner apparatus with cross axis correction
Inventor: DAVY BILL
IPC: G02B7/182
Filed: 1995-02-02
Abstract: A computer-to-plate machine 10 with a scanner head 12 having a resonant scanning mirror 36 mounted on a torsional wire 35, includes a cross-axis correction mirror 34 for correcting cross-axis (perpendicular to a scan line) error components in the beam. The uncorrected beam tends to describe an ellipse and the correction mirror is driven to remove the bow in the scan line and also to remove the zig-zag component which arises as the scanner head 12 traverses the platen (14, Fig. 4) so that the head produces substantially straight parallel lines in the forward and reverse scans. Wobble of the scanning mirror 36 is corrected. Mirror 34 is preferably a movable mirror driven by a piezo-electric transducer or an acousto-optic deflector. Elongate mirror 38 and laser 25 are shown.

Title: An electronic graphic system
Inventor: THROUP DAVID
IPC: G06T11/00
Filed: 1997-05-30
Abstract: An electronic graphic system 1 processes image data defining colour values of a multiplicity of pixels that together form an image. The system 1 comprises a processing unit 14 in which image data from an image store 2 is processed with other image data from a store 9.
