Title: Voltage distribution system in integrated circuits
IPC: H01L21/74
Filed: 1968-01-11
Abstract: 1,215,491. Integrated circuits. MOTOROLA Inc. 11 Jan., 1968 [23 Jan., 1967; 30 Oct., 1967], No. 1551/68. Heading H1K. In an integrated circuit certain P and N- type layers are arranged and biased so as to act as a distribution system for the supply of power or signal voltages to semi-conductor devices in the circuit. The structure shown illustrates the distribution of power to the emitters and collectors of several transistors. The regions 14, 16 are reverse biased with respect to one another and together with the linking vertical channels 20, 28, 29, 30 act as a transmission line with high distributed capacitance through which power may be fed from a source 11 to the collectors 21 of the NPN transistors and to surface contacts 64, 78 for feeding the emittersthe distributed capacitance decouples the supply. (In cases in which the system is used to supply signal voltages, the capacitance has to be kept down to avoid losses.) The structure shown is formed by growing a P-type layer 16 on an N-type body 14, and by forming vertical N-type channels such as 20 by diffusion into the grown layer. After this an N-type layer 21 is grown which is to form the collector regions, and P-type vertical channels 28, 29, 30 are formed in this layer by diffusion. Emitter, base and collector contacts are then applied as are electrodes 64, 65, 78 for giving access to the power supply.

Filed: 1974-01-15
Abstract: 1515503 Impulse transmitters GENERAL ELECTRIC CO Ltd 8 Jan 1975 [15 Jan 1974] 01800/74 Heading H4K A push button dialler which incorporates a digit store 7 and an impulsing transistor 9 is provided with an energizing source 11 that is charged from the line during loop makes so as to continue to supply power for store 7 during loop breaks. The transistor 9 is connected in series with a Zener diode 10 so as to provide a voltage drop of approximately 8 volts across a diode bridge 8. The capacitor 11 is in series with a constant current source 15. When the handset is lifted transistors 9 and 12 are initially unbiased and draw only a small current. However when a push button is operated, the voltage rise across the line terminals turns-on transistors 13 and 12 by current flow into capacitor 18 via diode 19 and the base-emitter path of 13. Consequently capacitor 11 begins to charge so that shortly afterwards store 7 may register the digit corresponding to the depressed push-button and cause the off-normal contacts 16 and 20 to open and close respectively. Transistors 13 and thence 12 are held-on by a bias supplied over resistor 21 during the period that store 7 holds any digit value. Transistor 14 is also on at this time. In order to provide a loop break impulse, store 7 forward biases transistor 23 via resistor 22 whence the transistors 13, 12, 14 and 9 all become non- conducting. Reference has been directed by the Comptroller to Specification 1.404,078.

Densified, finely-particulate nitrocellulose is produced by (a) dispersing water-wet fibres of nitrocellulose substantially free of fibre aggregates with shearing agitation in a mixture of a nitrocellulose solvent and a hydrocarbon diluent, so as to form a slurry, the mixture being capable of softening and swelling, but not dissolving the nitrocellulose fibres, (b) continuing the shearing agitation until substantially all the fibres are substantially uniformly softened, swollen and comminuted into the size range 100-500 microns, (c) diluting the slurry with continued shearing agitation, with an amount of a liquid which is a non-solvent for the nitrocellulose sufficient to form a layer of tough, densified nitrocellulose, substantially free of stickiness, enveloping each softened and swollen nitrocellulose particle so as to prevent agglomeration and continuing the agitation until substantially all the particles become smooth and rounded, the liquid non-solvent being water or the same hydrocarbon as used in step (a), and thereafter (d) diluting the resulting slurry with a large excess of the non-solvent as used in step (c) and subjecting the diluted slurry to distillation to remove substantially all the nitrocellulose solvent and the hydrocarbon diluent when the non-solvent is water or, when the liquid non- solvent is a hydrocarbon diluent, to remove substantially all the nitrocellulose solvent and water so as to complete the hardening and densification of the particles, whereby the desired product is obtained. Any nitrocellulose may be used, e.g. containing 10À9-13À5% N, and is advantageously subjected to a fibre beating step prior to step (a). A specified solvent is acetone; a suitable hydrocarbon diluent is heptane. Other solvents and diluents are mentioned.
