Title: Microstructuring superconductive oxide by irradiation using a resist masking technique
Inventor: KAUFMANN URSULA
IPC: G03F7/00
Filed: 1991-11-27
Abstract: In a process for microstructuring (the generation of areas or strips of different electrical conductivity) a superconductive oxide ceramic (1), in particular for the production of electronic components, the electrical properties of the oxide ceramic (1) are set by means of electromagnetic irradiation in the wavelength range of less than 1000 nm, such irradiation triggering a chemical reaction of the oxide ceramic (1). The method comprises the steps of applying a closed metal layer (3) onto the oxide ceramic (1); applying a photosensitive resist mask (4) onto the metal layer (3); removing those areas of the metal layer (3) not covered by the photosensitive resist mark (4); removing the photosensitive resist mark (4); applying the said irradiation to the oxide ceramic (1) which is partly masked by the areas of the metal layer (3) originally covered by the photosensitive resist mark; and removing the areas of the metal layer (3) originally covered by the photosensitive resist mask (4). Reversible reduction or oxidation of the oxide ceramic is triggered by the radiation causing the electrical conductivity of the exposed areas of the oxide ceramic layer to be specifically set, eg semiconductive highly resistive or insulating. The oxide ceramic is preferably YBa2 Cu3 O7.

Patent GB-2362528-A (GB)
Title: Radar
Inventor: HELLSTEN HANS
IPC: G01S13/02
Filed: 1994-05-31
Abstract: The invention relates to a radar station placed on the surface of the earth, and to a radar system comprising at least two such radar stations. The signal-processing equipment of the radar stations is adapted, at each point of time, to calculate probabilities of target positions and radial target velocity in relation to each individual radar station, based on the signals emitted and received by this station. These calculated values are associated over time, giving cumulative probability measures for target positions and radial velocities in relation to each individual radar station. By providing a system of at least two radar stations, it is possible to calculate the position of a target by associating target positions, such as they are perceived by the different radar stations, with each other by an association of characteristic movements of the target. This is done without having to synchronise the stations. If two stations are used, the target can be located in two dimensions; if at least three stations are used, it can be located in all three dimensions of space.

Abstract: A system for heating and/or cooling a plurality of separate locations (A - D) in a building comprises two heat-transfer circuits (6, 7), each circuit being adapted to circulate a heat transfer medium from a heat source or a heat sink to a heat exchanger (13 - 16) in each location, wherein the first heat-transfer circuit is able to supply the net cooling requirement of the heat exchangers and the second heat-transfer circuit is able to supply the net heating requirement of the heat exchangers during periods of conflicting requirements. The heat source or heat sink may be a heat pump. When only cooling is required, but the first heat-transfer circuit cannot fulfil all the cooling requests, the second heat-transfer circuit is able to switch to a cooling mode to support the first heat-transfer circuit. Similarly when only heating is required, the first heat-transfer circuit may be switched to a heating mode. The circuits may also be reversibly interconnected so that heat transfer medium in one circuit is able to flow through the other circuit. A heat pump unit for use in the system comprises a circuit containing a heat transfer medium which connects two or more primary heat exchangers, each heat exchanger being able to exchange heat with an associated heat-transfer circuit, with one or more compressors between the primary heat exchangers and one or more secondary heat exchangers adapted to alter if necessary the temperature of the heat-transfer medium in the circuit. <IMAGE>

Title: Engine with EGR management system
Inventor: MA THOMAS TSOI-HEI
IPC: F02M25/07
Filed: 1996-05-18
Abstract: In an ic engine having an EGR system, an EGR throttle valve 44 is rigidly connected to the main air intake throttle 14. The two valves 44,14 have similar cross sectional geometries so that the flow cross sections of the valves 44,14 are in a fixed predetermined ratio for all settings of the main throttle valve 14. To ensure this, the differential pressure across each valve must be equal and this is achieved by connecting the EGR pipe 42 to the exhaust system at a position 30 near the discharge end of the exhaust system so that the pressure upstream of the EGR valve 44 is essentially that of the intake air ie atmospheric. Fine adjustment may be made by closed loop control of an auxiliary source of EGR 24,50.

Title: A transistor for use in providing protection from electrostatic discharge
Inventor: CHOI JAE HOON
IPC: H01L29/08
Filed: 1996-09-30
Abstract: The present invention relates to a transistor for providing protection against an electrostatic discharge to which a semiconductor device may be exposed. The transistor includes means for minimising current crowding, which in one embodiment is achieved by arranging that where the length of the gate 73 is generally L, the length of the gate at the edges of the transistor is greater than the length L. In another embodiment, where the length of a gate is L over its whole extent, including at the edge of the transistor, and the gate is adjacent to the active regions, a groove is made in the edge of the device providing surfaces having an acute angle with respect to the gate. High-intensity electric field conditions are alleviated, the current is enabled to flow comparatively uniformly over the whole gate, and any heating effect is minimised, resulting in a prolonged life expectancy of the device.
