Title: Process for the Production of Semiconductor Devices
IPC: H01L21/18
Filed: 1967-12-07
Abstract: 1,192,440. Semi-conductor devices. MONSANTO CO. 7 Dec., 1967 [7 Dec., 1966], No. 55770/67. Heading H1K. [Also in Division C7] A method of manufacturing a semi-conductor device comprises the steps of depositing a coating on the surface of the semi-conductor body, removing selected portions of that coating to expose portions of the surface of the body, depositing by R.F. sputtering on to the exposed body surface an impurity doped material such as an oxide and then diffusing, in the temperature range 1100‹ to 1200‹ C. in a furnace, the impurity from the impurity doped material into the semi-conductor body. A passivating layer is then formed over the body where required and aluminium contacts are applied. The method is described as applied to silicon wafers to make diodes and transistors. In the method of sputtering used to deposit the impurity doped material on the semi-conductor body two impurity doped oxide wafers are used as the targets (24, 25), Fig. 1, not shown, in an evacuated bell jar (11), power being supplied from an R.F. generator. The target wafers are prepared by impurity diffusion from a vapour stage, and are mounted in overlapping fashion to form the targets, Fig. 6, not shown.

Title: Production of foams

Filed: 1971-12-21
Abstract: 1400157 Polymeric foams IMPERIAL CHEMICAL INDUSTRIES Ltd 1 Dec 1972 [21 Dec 1971] 59217/71 Heading C3R Polymeric foams, especially polyurethane foams are prepared by ejecting a mixture containing a polymer and/or prepolymer which is cured by contact with moisture and an inert blowing agent from a container in which the polymer and/or prepolymer is stored under pressure and injecting moisture into the stream of the mixture before it is exposed to the free atmosphere. It is preferred that the mixture be originally a liquid and for the moisture to be injected into the mixture whilst it is still a liquid at a position sufficiently close to the position where it is ejected from the container to ensure that the mixture remains substantially uncured at the moment of ejection from the container and this may be achieved by injecting the moisture into the mixture as the latter emerges from the container into the delivery hose. The moisture may be introduced as a vapour stream such as an air or nitrogen stream containing water vapour or as a jet of steam or an air/steam mixture. Ideally the pressure at which the moisture is injected is the same as that at which the mixture is ejected from the container. Conventional foam-forming polyurethane mixtures curable by contact with moisture are used.

Title: Sample Generating System
IPC: G01N1/00
Filed: 1978-06-23
Abstract: In automatic measurement of the atomic absorption of gaseous measuring samples, the samples are generated successively from a series of liquid samples by supplying a quantity of liquid sample to a reactor together with at least two liquid reagents to form a gaseous sample which is conveyed to the measuring cell 24 of an atomic absorption spectrometer by means of a carrier gas stream passing through the reactor. The reagents contained in reservoirs 50, 60 and are fed to the reactor 10 curing first and second periods of a measuring cycle and the liquid sample is fed during only the second period, both in countercurrent to the carrier gas flow from input 34 the reactor being subsequently emptied and washed. The feeding, emptying and washing are effected by piston pumps 44, 54, 64, 84 under control of camshaft 91. Liquid samples are supplied in succession to the reactor by a stepwise rotatable turntable mounted on a base plate which is movable between a first position in which one of the liquid samples 40 can be withdrawn into the reactor and a second position in which wash liquid from a receptacle 70 on the plate can be drawn into the reactor. <IMAGE>

Title: Electrical switch
IPC: H01H13/70
Filed: 1979-04-11
Abstract: This invention relates to retractive push-button switches for use with computer terminals, data recovery systems and the like. In order to provide an operating travel which is rather greater than the amount of travel actually required to operate a snap action click plate (14), there is provided a compression spring (16) between the click plate (14) and operating key (12). In its relaxed state, with the operating key in the outermost position as illustrated, the spring allows the click plate (14) to attain its relaxed position and when the key (12) is operated there is a period of lost motion until the spring (16) is sufficiently compressed to cause the click plate to snap to its operated condition. This gives an audible and tactile signal. A plurality of switches (2) may be snap-mounted on a p.c.b. (1) by means of feet (3), the plates (14) making permanent peripheral connections and having operational control contacts (15). <IMAGE>
