A plurality of semi-conductor components or integrated circuit(s) is manufactured by producing doped regions for the component by masked diffusion of a semi-conductor plate, etching (before or after the diffusion) away from one surface unwanted regions to a predetermined depth, forming electrical interconnections and removing material from the opposite surface until the components are linked only by the connectors. In the embodiment, grooves 10-50 Á deep are etched in one face of a silicon slice between regions of localized conductivity types produced by masking techniques to constitute various semi-conductor devices; an oxide layer 4 is then produced overlying the devices and grooves and again utilizing masking and etching processes, gold layers 5 are vaporized to interconnect the various regions. A coating 6 of epoxy resin is applied and then the opposite surface is etched in an HCl, HF mixture to remove material until the gold interconnections become visible; the exposed surface is then also covered with epoxy resin 6. Exposed input and output leads 5 are thermo-compression bonded to leads 7. The insulating resin may be a silicone resin or polyester and may comprise additives such as calcium oxide, boron oxide or calcium sulphate for drying purposes and aluminium oxide or magnesium oxide for heat dissipation; it may be applied by a mould which may form part of the final casing. The process may be used to provide integrated circuit or a plurality of transistor or planar diodes. The semi-conductor may comprise silicon, germanium or a compound semi-conductor.

Abstract: 149,262. Quiry, A. G., (Assignee of Marcadet, J.). Jan. 21, 1914, [Convention date]. No Patent granted (Sealing fee not paid). Soldering.-In a soldering iron of the kind in which the bit is mounted on a pivot at the end of the handle and formed with flats or recesses co-operating with means on the handle for fixing the bit at various inclinations, a separate bit fixing stem is incorporated with the handle to avoid handling of the bit during adjustment. In the form shown in Fig. 1, a bit 1 provided with a recess 4 lined with an overlapping piece of sheet nickel or like 5, is mounted on a pivot 8 passing through an eye 7 in a rod 6 which is mounted in the handle stem 9. The rear end of the bit is bevelled at 3 to furnish three angular positions, and it is pressed down against an enlarged seating 10 on the stem 9 by a spring 20 mounted in the metal lining 14 of the handle between the end of the stem and a washer 19 and nut 18 screwed to the end of the rod. The clamping pressure is obtained by tightening the nuts. To release the bit prior to altering its position, the nut is slacked back and the rod pushed up, or the bit pressed against some fixed object. A pin 15 in the rod is guided in slots 16 in the stem. In the form shown in Fig. 6, the rear end of the bit, which is rounded and covered with a sheet of nickel &c. 5, is mounted on a pivot 8 in a partially-rounded recessed seating 10 on the stem 9, and has a series of holes 23, 24, 25, with which engage the pointed end 31 of a rod 26, which is pressed upward by a spring 27 and withdrawn by pressing down the push button 29.

Abstract: 1401547 Power distribution systems M BREITMEIER 4 May 1973 [5 May 1972] 21322/73 Addition to 1344186 Heading H2H An electrical power distribution system comprises a main line H1, secondary lines M1-M5, N1-N5 each coupled to the main line and including a pair of branch lines Z1, Z2, and an output regulator in one branch line of each pair of branch lines for regulating the power in each secondary line so that the terminal voltage thereof remains above a predetermined minimum value. Each line M1-M3 feeds a low energy consumption load such as a household having a load A comprising household appliances and a load H such as an electric heater. Each branch line Z2 includes the output regulator in the form of a voltage regulator R1 and each branch line Z1 includes a power meter 3 and a power limiter 4 which keeps the power in the line Z1 below a maximum value. The terminal voltage of each secondary line is monitored by a voltmeter V and the regulator R1 compares this voltage with the predetermined minimum value to deliver only enough power to the line Z2 so that the actual terminal voltage is not less than this minimum value. The meter 3 supplies an output signal to the regulator R1 so that the regulator supplies power to the line Z2 equal to the difference between the maximum power for the secondary line M1 and the actual power in line Z1. The lines N1-N5 supply high energy consumption loads and voltage regulators L1- L3, which are similar to the regulators R1-R3, receive additional control signals from a control device S. The main line H1 includes a power meter M which supplies an output signal to the device S to enable this device to control the regulators L1-L3 so that in the event of an overload in the main line H1, the acceptable output in the branch line Z2 is reduced.

Abstract: 668,267. Compound sheet material; coating webs. CHAVANNES, M. A. Aug. 6, 1947 [March 30, 1945], No. 21372/47. Class 140. A sheet-like, heat-sealable, moisture-vapourproof wrapping or protective material, capable of being freely flexed, folded and creased, includes two layers of self-sustainable, flexible, thermoplastic resinous film united with the two faces of a layer of metal foil, and a. layer of lightweight but coarse fabric adhesively bonded to the outer surface of one of the layers of film, one surface of the other layer of film being exposed and providing a heat-sealable surface for the sheet material. As shown, Fig. 1, aluminium, zinc, lead or tin foil 14 from a roll 15 is supported on a carrier web 10 and passed beneath a coating roller 12 where it receives a film of resinous coating material from a hopper 17. Scrim 20 is pressed on to the film by the weight of its own roll 19, and the material then passes through a dryer 21 after which it is wound in a roll 23. To avoid crinkling of the foil, the temperature in dryer 21 is a maximum prior to the setting of the film. A second coating of resin is then similarly applied to the other side of the foil, and the material is passed through the dryer 21 again. The final sheet, Fig. III, may include, in addition to the foil 25, resinous films 24, 26 and scrim 27, a coating 28 of pressure-sensitive adhesive, which may consist of a mixture of isobutylene and a hydrogenated rosin. The resin coating composition may comprise a copolymer of vinyl acetate and vinyl chloride with plasticizer and' an adhesive, e.g. an acrylic resin or synthetic rubber or a mixture thereof, or a vinyl resin of low molecular weight. The resins are carried in a solvent, or as a dispersion in a diluent, e.g. xylol or naphtha; in the latter case the film is subjected in the dryer, after removal of the diluent, to a temperature at which the resin will fuse. Each resinous layer may include metal flakes up to 10 per cent of the weight of the other solids. Instead of a vinyl copolymer, the resin films may be of nylon, polybutyral, polyethylene, polyisobutylene, or polystyrene. The scrim may be formed from cotton, rayon or glass fibre. A suitable adhesion between film and foil is such as will require a force of 1-5 lb. per inch width to strip the film from the foil. U.S.A. Specification 2,443,443 is referred to.
