摘要： A remote operated vehicle control system comprises a remotely controlled vehicle (1) carrying a television camera (4), the camera (4) and vehicle (1) being connected by a radio link (6) to a separate base station (2) having a radio receiver (3), in which the video picture for transmission is divided into separate data sets one part of which exhibits short timescale variations and another part of which exhibits long timescale variations, the two data sets being transmitted at differing video frame rates, and means at the receiver for combining the two transmissions to give a composite picture on a video display of said receiver (3). This system can allow good control of the vehicle without demanding a high bandwidth radio link.

摘要： A method is described of manufacturing perovskite lead scandium tantalate comprising the pre-reaction of scandium and tantalum oxides at temperatures between 1000 DEG C and 1400 DEG C to form scandium tantalate. The scandium tantalate is then reacted with lead oxide to form the desired perovskite phase lead scandium tantalate. In one embodiment there is described a method for the deposition of perovskite lead scandium tantalate films from metal organic precusors. The availability of metal organic precursors allows the deposition of thin films directly from solution or by MOCVD techniques. One particular material, lead scandium tantalate Pb(Sc0.5Ta0.5)O3, is described. The principal features of the invention are the deposition of scandium and tantalum components from solution or by MOCVD onto the required substrate. These are then prereacted to yield scandium tantalate. A lead containing film or vapour is then reacted with the scandium tantalate to form the perovskite phase lead scandium tantalate.

摘要： A microwave circuit element comprising a body of an electrically conductive material which has non-linear resistance properties, the body being in the form of a film supported on a substrate (2) of dielectric material, the said body forming part of a microwave transmission path (1) such that an incident electrical field (Pi) having an intensity below a predetermined threshold level will be transmitted as field (Pt) by the body whilst a field (Pr) of strength greater than the threshold level will be reflected or diverted. The element can thus provide protection of the sensitive receive components in a radar system.

摘要： An integrated logic circuit comprising bipolar transistors (16, 18) and junction field-effect transistors (12, 14). The junction field-effect transistors (12, 14) are arranged in the circuit to serve as switching elements, the gates being connected to the bases of the respective bipolar transistors (16, 18). The channels of the junction field-effect transistors are formed in the integrated structure design as ''pinch'' resistors defined by a P or N doped region of the same or similar type to that used to define the sub-emitter base resistance in the bipolar transistors (16, 18).

摘要： A semiconductor switching element including a FET and transmission line (11, 13) whereby the transmission line is mounted around the active channel (15) of the FET with a gate electrode stripe (17) therebetween. The transmission line (11, 13) is thus capable of being short-circuited to earth by application of a suitable electrical potential to the gate electrode. This allows construction of a microwave phase shift circuit which makes maximum use of the available area of semiconductor material.
