Title: High density read-only memory

Filed: 1972-09-26
Abstract: 1374881 Read only memory ROCKWELL INTERNATIONAL CORP 26 Sept 1972 [23 Dec 1971] 44493/72 Heading G4A A read-only memory is formed in a semiconductor substrate having a series of spaced, parallel conducting regions 20-28 and includes a plurality of address lines A 1 -A 8  connected to enable respective groups of a plurality of field effect transistors 29-51 which interconnect adjacent conductive regions in accordance with the stored data, and a plurality of selection lines S 8+1 -S 7+  8  connected to enable respective groups of a plurality of field effect transistors 19 and 52-61 which connect the conductive regions with which they are associated to a reference potential (e.g. earth)-or to a common output 71, alternate conducting regions being connected, via the appropriate transistors to the reference potential and the remaining regions being connected, via the appropriate transistors, to the common output. In operation the conducting regions 20-28 are precharged to - V volts by enabling FETs 62-70. Following the precharging a particular bit storage location is addressed by applying an address signal to a selected address line A 1 -A 8  and a select signal S 1 -S 8  to the pair of select lines which include the relevant suffix, e.g. in the case of S 1 , S 8+1  and S 1+2 . Assuming A 1  and S 8+1  and S 1+2  are selected FETs 19, 52, 53, 29, 37, 42 and 47 will be enabled. Regions 20 and 21 are thus connected to ground and to output 71 respectively, all other regions remaining isolated, e.g. region 28 since although FET 19 is enabled FET 61 is not. As shown regions 20 and 21 are connected to each other via FET 29 so that region 21, and hence output 71, as well as region 20 are discharged to earth. If however FET 29 had been omitted regions 20 and 21 would not have been connected and region 21, and hence output 71, would not have discharged. A signal is thus produced at the output 71 in accordance with the presence or absence of FET at the selected bit location. Any one of 64 stored bits may be read out at output 71 by providing the appropriate address and select signals, a plurality of similar memory planes, addressed by the same signals, being provided, one for each bit of a stored word.

Abstract: 1,144,850. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORP. 2 Oct., 1967 [13 Oct., 1966], No. 44699/67. Heading H1K. An integrated circuit comprises a substrate 10 of N(P) type semi-conductor material, e.g. silicon, having an insulated-gate fieldeffect transistor comprising P + (N + ) source and drain regions 12, 13 and a channel region 14 formed therein and an epitaxially deposited region 20 of uncompensated P(N) type material formed within the substrate 10 and having an insulated-gate field-effect transistor of opposite conductivity type and comprising N + (P +) source and drain electrodes 22, 23 and a channel region 24 formed within the epitaxially deposited region 20. The recess for receiving the region 20 is formed by vapour-etching with an agent such as hydrogen chloride. The recess may as an initial step be lined with a thin layer of P(N) type material formed by diffusion, the region 20 being subsequently formed by an epitaxial process such as by the thermal decomposition of silicon tetrachloride with hydrogen in the presence of a doping agent such as borane. The recess for the region 20 may initially be formed with a greater depth than that finally required and then overfilled with epitaxially deposited silicon, the whole body then being lapped to reduce the region 20 to the desired thickness.

Filed: 1965-10-22
Abstract: In the preparation of dry cake mixes, finely divided molten fat is sprayed into the pulverulent constituents which are either falling freely, or are in a state of retarded fall, for example by falling through an upcurrent of air.  The fat preferably has a melting point of 20-35 DEG C., and is present in 5-30% wt.  Other optional constituents include starch, sugar, yeast, salt, and egg, milk, and baking powders.

A heat exchanger consists of tube units 100 arranged in a shell 70, all the tubes extending between inlet and outlet header compartments 11, 13, respectively, at the ends of the shell for a fluid, e.g. water flowing through the tubes. Each unit 100 consists of a mass of fluid pervious material in which tubes 90 are embedded for part of their length said mass having a central bore 10. Each unit also comprises at least one tube plate (e.g. 40) and these are connected each into a corresponding opening (31-36, Fig. 4) in a large tube plate 30. Alternatively the tube plates of the units are connected together to form a large tube plate (Fig. 7). Inlet and outlet compartments 12, 14 for a fluid, e.g. oil flowing over the tubes are formed in the shell space by a partition 30 having apertures (42, Fig. 5A) therein each coinciding with a bore 10 of a porous mass. The shell side fluid passes into the compartment 12 through a shell inlet 73 and from there flows into the bores 10 and radially through the masses (and over the tubes embedded therein) finally leaving the shell through an outlet 74. The heat exchanging fluids may be gaseous. In a modification (Figs. 7, 8) the shell side fluid makes two passes over the porous material before discharging from the shell. Methods of assembly are described. In one method the tube end plates of the tube units are formed as quadrants four of which are joined to form a circular plate which is then inserted in the shell (see Fig. 7).
