Title: Methods of forming a field effect transistor
Inventor: FEIST WOLFGANG M
IPC: H01L29/808
Filed: 1984-01-27
Abstract: A method of forming a FET includes the step of forming an elongate buried region 30 below, and spaced from, the gate electrode 44. The buried region is electrically connected to the gate electrode 44 where it breaks through to the electrode at the edges of a mesa layer. The method includes the step of forming a pair of masking strips 14, 16 of insulating material on the surface of the semiconductor. An ion implantation masking layer is formed between the pair of masking strips to enable the selective implantation of particles in the semiconductor to establish the source and drain regions 22, 24. With such method a single masking step is used to define the source, drain and gate regions of the device, namely the masking to define the strips 14 and 16. The buried layer is formed by deep ion implantation with the source and drain masked or without masking so that there is shallow implantation under the strips 14, 16 and deep implantation elsewhere. Gate oxide may be deposited between the strips before implantation. The device may be formed in a semiconducting mesa on a sapphire or similar substrate. <IMAGE>

Title: Image processing system
Inventor: BURGESS DOUGLAS EDWARD
IPC: G08G1/015
Filed: 1984-02-14
Abstract: An imaging system is used to monitor numbers and type of vehicles 1, 2, 3 approaching e.g. bridge 5 subject to weight restrictions. The system uses a fixed vertical array 11 of sensors to produce an image of vehicles passing the array. Photo, infra red, or radar sensors may be used. The sensors 11 are sampled e.g. at 50 times per second and the resultant information stored in a read/write memory array (25). About e.g. 40 seconds of sampling is held in store. Once full the memory (25) is overwritten with new information. Part of the memory at a time is read out onto a television monitor screen (48). By varying the read address positions (31, 33) for each television field an observed vehicle 2 is given a movement across the television screen (48). Also the read address positions (31, 33) can be varied to give a pan effect so the vehicle can be held stationary or moved quickly backwards or forwards across the screen. <IMAGE>

Title: Improvements in and relating to pressure swing oxygen generation systems
Inventor: ARMOND JOHN
IPC: B01D53/047
Filed: 1986-10-06
Abstract: In a pressure swing oxygen generation system of the kind in which two exchangeable adsorption beds are coupled cyclically and in alternation to sources of elevated and reduced atmospheric pressure, the instant at which the input to one bed is connected to the source of reduced pressure after having been connected to the source of compressed air is delayed in relation to the instant at which the input to the other bed is switched from the source of reduced pressure to the source of compressed air. In this manner, reduction of the gas pressure prevailing within the reservoir supplied by such a system is partly avoided. <IMAGE>
