Title: Interconnections for integrated arrangements
IPC: H01L23/29
Filed: 1972-06-07
Abstract: 1365261 Integrated circuits SESCOSEMSOC EUROPEENNE DE SEMICONDUCTEURS ET DE MICROELECTRONIQUE 7 June 1972 [9 June 1971] 26643/72 Heading H1K Ohmic contacts, interconnection tracks and interconnection resistors are all provided in a monolithic integrated circuit by a structure basically comprising a lower layer 7 of a relatively resistive metal such as Zr, Hf or Ta and an upper layer 8 of a more highly conductive metal such as Al. The ohmic contacts, e.g. to the emitter and base regions of the transistor illustrated, and the direct interconnections between circuit elements, are formed by the two layers 7 and 8 together. Where it is desired to provide a resistor in an interconnection track the corresponding portion of the Al layer 8 is removed to leave an exposed portion 11 of the relatively resistive layer 7. Elsewhere, where isolation between elements is necessary, such as at area 10 between the base and emitter contacts of the transistor, the upper layer 8 is selectively etched through and the thus exposed layer 7 is either removed, as by etching, or is rendered insulating by thermal oxidation to form the metal oxide.

A storage device for lowered aircraft arresting gear comprises a trench in the ground located beneath the arresting gear when in its raised position, and angularly movable lids hinged along one or both sides of the trench at ground level and serving to gather the arresting gear when lowered and to put it into the trench. In the embodiment described, the arresting gear comprises a net (not shown) which when raised lies over a trench 6. Each lid 7 comprises a thickened portion 17 connected by an incline 18 to a thinner portion 9. Each lid is connected to the trench by a hinge 8, and to the adjacent lid by a pin 10 fitting into a socket (not shown) in the adjacent lid. The incline 18 assists the wheels of a landing aircraft or other vehicle moving from left to right, to pass over the trench. Further interconnected plates 11 are hinged to the other side of the trench. When the net is lowered, it falls partly on to a grid 12 in the trench and partly on to the lids 7 and plates 11. These are then raised to a vertical position, the whole of the net then falling into the trench. The plates 11 are then returned to the position shown, and lids 7 continue their angular movement to tie over and cover the trench. A heating element 13 running beneath grid 12 is used in case of frost, and the lower part of the trench serves as a drainage channel. The movement of the lids and plates may be effected automaticaly by a single motor located centrally of the trench.

Abstract: 292,402. Siller & Rodenkirchen Ges., and Siller, W. Cct. 15, 1927. Refrigerating, condensers for. - The gas such as ammonia is initially chilled and liquefied by heat interchanging surfaces over which flows rapidly a thin steam of cooling liquid, and the aftercooling of the liquefied fluid is effected by surfaces immersed in slowly moving cooling liquid. The condenser comprises an annular receptacle A mounted on a drum q traversed by longitudinal pipes a, b, c secured to end walls d. A pipe h feeds cooling liquid to the bottom of the receptacle A the inner walk e of which is lower than the outer wall o so that the liquid overflows into a space B whence it flows rapidly in thin steams down the inner surfaces of the pipes a, b, c. The gas entering the drum q at p is condensed and collects at the bottom of the drum, serving as a chilling medium through which the entering gas has to bubble. The condensate is forced up a pipe f to a coil s immersed in the cooling liquid flowing slowly through the receptacle A, and is discharged through a pipe g. The outer surface of the drum q may also be swept by liquid from the space B but as shown is cooled by a separate supply of cooling liquid through an inlet k into an annular gutter C supported on the drum c by ribs which allow the liquid to flow down the outside of the drum. In a modification, the drum q has in its centre a jacketed pipe to which condensate is led for after-cooling, the cooling liquid passing first to the jacket of the pipe and then into an annular gutter whence it overflows into the upper space of the drum q.
