Title: Light responsive circuit arrangement
IPC: G06G7/24
Filed: 1972-07-28
Abstract: 1401532 Photo-detector circuits TEXAS INSTRUMENTS Ltd 28 July 1972 35427/72 Heading G1A [Also in Division H3] A logarithmic output photo-detector comprises a photodiode connected between a reference potential and the input of a D.C. amplifier the output of which is connected to a logarithmic element producing a feedback current and a logarithmically related output voltage, the feedback current being applied to the input of the amplifier in such a sense as to maintain substantially zero voltage across the photodiode whereby the output voltage is logarithmically related to the intensity of the light incident on the photodiode. As shown, a commercial I.C. operational amplifier OAI provided with a high impedance discrete component differential input stage (see Division H3) is connected to a photodiode D1 and is provided with a negative feedback path so that the diode is connected between earth and a virtual earth and operates with zero voltage across it resulting in a linear relationship between light intensity and output current. The current produced by the photodiode flows through the feedback loop and passes through transistor VT7. A second, matched transistor VT8 has its base connected to its collector and is provided with a high value load resistor so that it draws substantially constant current. Since the differential base voltage of the transistor pair VT7, 8 is logarithmically related to the ratio of the collector currents and the circuit is arranged so that VT8 draws constant current and the base of VT8 is earthed, it follows that the base voltage of VT8 is logarithmically related to the collector current of VT7 and hence to the photodiode current. The logarithmic output is applied to a second operational amplifier OA2 which has a feedback loop containing a temperature sensitive silicon resistor in series with a normal resistor proportioned to offset the temperature dependance of the logarithmic converter transistors. The output of op amp OA2 is applied to a meter Ml which provides a reading logarithmically related to the intensity of the radiation falling on the photodiode D1. The detector may be used as a densitometer with a linear density scale. A reference density level may be set by means of a potentiometer P1 in the feedback circuit of the output amplifier OA2. The spectral response is similar to that of the human eye so that the detector may be used for colour analysis, but an IR filter may be necessary to reduce the effects of relatively high levels of IR radiation. The meter may be calibrated in terms of photographic exposure.

Title: Reduction of parasitic bipolar effects in igfet integrated circuits
Inventor: CRAWFORD ROBERT HUDSON
IPC: H01L29/78
Filed: 1969-07-15
Abstract: 1279314 FET storage circuits TEXAS INSTRUMENTS Inc 15 July 1969 [9 Sept 1968] 35579/69 Heading H3T [Also in Division H1] In an integrated circuit comprising a number of IGFETs the source and drain zones of which are formed by diffusion into a common substrate region of opposite conductivity type, bipolar transistor action caused by the PN junction between any of these zones and the substrate becoming forward biased is reduced by the presence of a diffused collection region adjacent each or all of the regions. The described arrangement, shown in part in Fig. 4, is a capacitive pull-up multi-phase shift register each half-bit of which as shown in Fig. 5 comprises two IGFETs e.g. Q1, Q2 and a capacitor the physical locations of which are marked in Fig. 4. The collector region 80 which surrounds each half-bit forms a continuation of the earthed source electrodes of transistors Q1, Q3. It thus eliminates transistor action between adjacent half-bits and because of its proximity to the source and drain regions of the surrounded transistors greatly reduces it within each halfbit. It may be at the same potential as or reverse biased relative to the substrate and is formed in the same oxide masked diffusion step as the sources and drains. Subsequently after thinning the oxide at the sites of the gates and capacitors the aluminium metallization pattern shown is formed.

Title: Improvements in lacquers on the basis of epoxy resins
IPC: C08G59/44
Filed: 1955-12-20
Abstract: Air drying lacquers, which after stoving give coatings resistant to chemical reagents, comprise a mixture of an epoxy resin and the reaction product of a multi-unsaturated fatty acid with conjugated double linkages, e.g. sorbic acid or the acids obtained by dehydrating castor oil or ricinoleic acids with a polyamine; a small part of these acids may be replaced by unconjugated unsaturated acids, e.g. oleic, ricinoleic or linoleic acids.  The mixture may be applied in solution, e.g. dissolved in a mixture of butanol and xylene ketones or glycols.  The epoxy resins employed are those obtained by reacting aromatic, aliphatic or hydroxyaromatic polyhydroxy compounds with alkylene oxides or epihalohydrins.  In examples: (1) a 40 per cent solution in butanol and xylene of the amide obtained by reacting under nitrogen pressure propylene diamine with dehydrated castor oil acids is mixed with a 40 per cent solution in a methyl isobutyl ketone, ethyl glycol, toluene (1 : 1 : 1) mixture of an epoxy resin obtained by reacting 4,41-dihydroxydiphenyl dimethylmethane with epichlorhydrin; (2) the amide employed is obtained by reacting ethylene diamine and dehydrated ricinoleic acid; (3) the amide employed is obtained by reacting propylene diamine and dipropylene triamine with dehydrated ricinoleic acid.ALSO:Amides of fatty acids having conjugated double bonds are prepared by reacting polyamines with the acids such as sorbic acid, dehydrated castor oil acids or dehydrated ricinoleic acid. Specified polyamines are ethylene, propylene and tetramethylene diamines, diethylene and dipropylene triamines, diamino cyclohexane and diamino - dicyclohexyl - methane.  Reaction is preferably effected under pressure in an inert atmosphere such as that of nitrogen or carbon dioxide at 230-280 DEG  C.  In general, the amount of polyamine used is from 10-70 per cent by weight of the fatty acid.  In examples: (1) 600 parts of propylene diamine and 1400 parts of dehydrated castor oil acids are heated under a nitrogen gas pressure at 265 DEG  C. for 2-2 1/2 hours and then further heated under atmospheric pressure, the product having a M.W. of 620; (2) ethylene diamine is similarly reacted with dehydrated ricinoleic acid; (3) the acid of (2) is heated with a mixture of dipropylene triamine and propylene diamine under nitrogen at 260 DEG  C. while distilling off the water formed. The products are curing-agents for epoxy-resins.
