Title: Improvements in or relating to Minimum Detector Circuits
IPC: B65H67/04
Filed: 1966-03-10
Abstract: 1,154,332. Peak signal detectors. FOSTER GRANT CO. Inc. March 10, 1966 [March 10, 1965], No.58404/68. Divided out of 1,154, 331. Heading G1U. In a minimum detector for detecting the minimum of a signal which may vary between zero and a predetermined maximum of a given polarity the signal, on line 116 is applied together with a bias, greater than and of the same polarity as the maximum, on line 117 to the input of a first high gain inverter amplifier 110. The output from this is connected via a diode 124, and second amplifier 127 to a third amplifier 130, which has a storage capacitor 135 connected across it. A feedback path 134 is connected between the third amplifier output and the first amplifier input. A resetting potential may be connected via the switch 136 to the third amplifier input. In the system shown, the polarity of the signal under investigation is wholly negative. For the system to operate, the switch 136 must be opened. The system responds to signals of decreasing absolute magnitude as an inverter amplifier, and the output at 135 follows such signals. However for signals of increasing absolute magnitude, the diode 124 cuts the amplifier off and the output at 135 will be the minimum magnitude as stored on the capacitor 135. The output at 133 is compared with the input on line 116 at the input of amplifier 140. When the input is of decreasing absolute magnitude, this will be slightly positive due to a bias from the resistors 142, 143, the Zener-diode 146 conducts and no output is provided into the winding 72. When the input signal magnitude starts to increase (in a negative direction, of course) the input of amplifier 140 becomes negative and an output is delivered into the winding 72. This is used to operate the switch 136 to apply negative potential to the third amplifier input and reset the detector. The detector is used in arrangements for analyzing chromatograph peaks, more fully described in Specification 1,154, 331. When a minimum is to be searched for, the cycle timer in the analyzing equipment sets the switch 136. The pulse in winding 72 produced in response to a detected peak operates, inter alia, the switching arrangements in the equipment for separating the individual peaks.

Title: Monolithic integrated circuit structure and method of fabrication
Inventor: BEAN KENNETH ELWOOD
IPC: H01L21/00
Filed: 1969-12-01
Abstract: 1,260,434. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 1 Dec., 1969 [17 Feb., 1969], No. 58519/69. Heading H1K. A monolithic integrated circuit comprises a polycrystalline silicon matrix having an oriented needle-like grain structure with a plurality of monocrystalline islands in said matrix and circuit elements located in said islands and interconnected. Polycrystalline material of such a structure is said to exhibit anisotropic electrical and thermal properties, in particular the resistivity perpendicular to the grain direction is greater than that parallel to the grain direction. The device is formed from a monocrystalline body (11), Fig. 1 (not shown), which has a patterned oxide mask (12) on one surface with "windows" (13) revealing the body (11). The "windows" may have one side parallel to the intersection of a (111) plane with the (110) plane of the body surface. Silicon is deposited epitaxially, that deposited above the "windows" (13) being monocrystalline and of the same orientation as the body, that on mask 12 being polycrystalline, and the deposition conditions are such that the needlelike grain structure has its axis perpendicular to the body surface. The silicon body (11) is removed to leave monocrystalline islands 14 in a polycrystalline matrix 15. Circuit elements may be formed in each island 15, and gold may be diffused into the islands from the bottom surface to central minority carriers. In a second embodiment the epitaxial layer is restricted in thickness and covered with an oxide layer, on which is deposited a thick polycrystalline layer. The silicon body is removed to leave a plurality of monocrystalline islands supported by a polycrystalline substrate isolated by an oxide layer. Circuit elements may again be formed in the islands. In a third embodiment a low resistivity layer of the same conductivity type as the body is deposited on one surface of the body, and channels etched through this layer and into the body to form a pattern of raised islands. Epitaxial deposition follows, the conditions being such that a thin layer of amorphous silicon is at first formed, to interrupt the monocrystalline lattice, followed by the needlelike grain structure. The body is then removed until the channels are reached when circuit elements may be formed in the isolated islands.

Abstract: 1,248,398. Titanium dioxide; titanium tetra- Chloride. LAPORTE TITANIUM Ltd. 23 Dec., 1968 [29 Dec., 1967], No. 59203/67. Headings C1A and CIN. A process for making titanium dioxide comprises chlorinating titanium-bearing material to produce titanium tetrachloride, which is then oxidized to produce titanium dioxide suspended in a chlorine-containing gas stream, separating from the gas stream titanium dioxide and any other suspended solids, passing the separated gas, at a temperature not more than 50‹ C., through a scrubber containing concentrated sulphuric acid, compressing the scrubbed gas using a liquid piston compressor in which the liquid is concentrated sulphuric acid, passing the compressed gas through a mist filter, and using the filtered gas to chlorinate further titanium-bearing material. A fluidized bed may be used in the chlorination, the filtered gas entering the reactor through apertures in its base. Before entering the scrubber, the separated gas stream may be cooled to a temperature of - 15‹ C. to the melting point of titanium tetrachloride. The sulphuric acid in the scrubber is desirably replaced, periodically or continuously with acid of nil or low titanium content so that the concentration of titanium (expressed as tetrachloride) in the acid in the scrubber is maintained below 10% by weight. The " low-titanium " acid may be recycled from the compressor, which is then replenished with sulphuric acid containing substantially no titanium. The oxidation may be carried out in a fluidized bed as described in Specification 815,891, or by a method involving separately preheating the reactants, as described in Specifications 1,049,282 and 1,173,592. The separation of the chlorine-containing gas stream may be effected by depositing a bed of solids from a low-velocity gas-stream and passing inert gas therethrough, as described in Specification 1,098,881.

Abstract: 1,210,000. Sealing with glass. TOKYO SHIBAURA ELECTRIC CO. Ltd. 18 Dec., 1968 [25 Dec., 1967; 19 Feb., 1968; 10 Jan., 1968], No. 60186/68. Heading C1M. [Also in Division B3] To seal workpieces with glass solder, particularly parts of glass, metal or ceramics, soldering glass 14 is caused to adhere to the tip 11a of a soldering iron 11 (or 41, 56), the adhered glass is heated to cause it to melt and is then deposited on to the seal portion of the workpiece 15 (or 41, 57). With reference to Figs. 1A-1D, the soldering iron tip 11A is indirectly heated by a heater 12 surrounding iron 11 and is initially preheated, dipped with a bath 13 of molten solder 14 and positioned adjacent the tube workpiece 15 so that on reheating the solder glass encloses the end of tube 15 to seal it. The tip 11A is preferably of nickel-iron alloy, platinum or molybdenum and may have differing shapes including a tubular form (as 56) or similar to a drawing pen, which can carry a greater volume of soldering glass for sealing broad openings (as with bulbs 57). A further form with direct heating of the tip consists of a wire coil 41, Fig. 5, supported in a heat-insulating tube 42 with handle 43, the wire 41 being connected to a power source 46 with switch 45 and adjustable stabilizer 44 by which initial low heating and final heating to sealing temperatures can be effected. The tip 41 may be of nickel, carbon, molybdenum or tungsten and the coil 41 may be replaced by a plate or cylinder. To ensure that the temperature of the workpiece is sufficiently raised to ensure a good seal, electric current may be passed through the soldering glass via the soldering iron and the metal workpiece. As shown in Fig. 7B, a tubular soldering iron 56 with collected solder glass 14 is pressed against the end of a glass bulb 57 to seal in lead wires 58a of lamp filaments 58, current being pasesd through the solder glass 14 from a source 55 through a stabilizer 54, the soldering iron 56 and the extended wires 58a. Sealing may be effected in an atmosphere of argon or nitrogen so that evacuation and sealing of the bulb 57 can be effected simultaneously. The soldering glass used should have a thermal expansion coefficient equal to or approximating that of the workpiece.

Abstract: A repetitive signal is switched by digital colour-separation signals and the switched repetitive signals and the colour-separation signals are summed. The repetitive signal has preferably the same frequency as the colour sub-carrier frequency or is an integral sub-multiple of it. In a single-bit digital colour-separation signal version, in the red channel NAND-gates (42Ru, 42Rv) have respective repetitive signals (50u, 50v) and the red colour-separation signal (48R) applied to their inputs. The outputs of the NAND-gates (42Ru, 42Rv) and the colour separation signal (48R) are connected to respective current-defining means (58Ru, 60Ru; 58Rv, 60Rv; 58R, 60R) and the resultant currents are fed to a summing amplifier (56), together with similar blue and green channel signals (70). The repetitive signal is preferably a square-wave, but may be, for instance, a rectangular wave. Various vector relationships between the repetitive signals for each colour are possible, to a large extent being dependent on the relationship between the repetitive signal fundamental frequency and the colour sub-carrier frequency. <IMAGE>
