Patent GB-1279742-A (GB)
Title: Film conductor
Inventor: AINSLIE NORMAN GEORGE
IPC: H01L21/28
Filed: 1971-01-04
Abstract: 1279742 Semi-conductor devices; printed circuits. INTERNATIONAL BUSINESS MACHINES CORP 4 Jan 1971 [8 Jan 1970] 257/71 Headings H1K and H1R A film conductor comprises a metal containing an additive for retarding current induced mass transport of the metal. Reservoirs of the additive are disposed adjacent points where mass flux divergences, which cause depletion of the additive, occur. Such divergences occur, e.g. at interfaces with other materials in the current path and in thermal gradients. The depleted material is periodically replenished, e.g. six-monthly, from the reservoirs by heat treatment at 50-550 C. Typically, the conductors are of aluminium and contain copper as retardant. Iron, magnesium and silver are other retardants and the invention can also be applied to conductors of silver, gold and platinum. The conductors described constitute interconnections between integrated circuit devices formed in a silicon wafer by known planar techniques. A first layer of interconnections is first deposited over a silicon oxide, nitride or alumina passivating layer and form etched, a further layer of the insulant is then laid down, as by RF sputtering, and apertured at interconnecting points, and then a second layer of interconnections. Finally, a protective silica layer is deposited and apertured at terminal land locations where ball contacts are provided. The metal layers, e.g. of copper-doped aluminium, to which 3% by weight of silicon may be added to limit alloying to the silicon, are formed at a substrate temperature of 200 C. by evaporation from an alloy source, by co-evaporation from separate sources or by sequential evaporations of copper and aluminium followed by a heat treatment. Between these processes copper is deposited locally where required (see Figures, not shown) and overlain with chromium to improve the adhesion of subsequently deposited insulation. The invention may also be used with conductive films or substrates for interconnection to semi-conductor and other electronic devices.

Title: Improvements in and relating to windshield wipers
IPC: B60S1/34
Filed: 1941-01-09
Abstract: 546,431. Securing windscreen-wiper arms on shafts. TRI,.CO PRODUCTS CORPORATION. Jan. 9, 1941, No. 335. Convention date, April 25, 1940. [Class 80 (ii,)] The wiper is carried by a resilient arm which is mounted on an oscillating shaft 4 and comprises an inner end section 8 to which is pivoted at 19 a channelled sheet-metal stamping 18 into which is telescoped a leaf spring 20. The shaft 4 carries a fluted head 5 which receives a fluted socket on the end section 8 thus providing a means of adjusting the position of the wiper on the windscreen. The end wall of the socket may be formed as a separate plate 10 secured by a rivet 19 or may be cast with the socket. The section 18 is held from axial movement by a spring latch 13 which is accommodated in a groove 12. In a modification, Fig. 6, the latch is mounted exteriorly of the socket between the side walls 27 of the inner end section. These side walls have outwardly flaring holes 28, Figs. 7, 8, in which are pivoted the trunnions 29 of the spring-wire. latch. This has parallel legs 30 which at their outer ends have a pair of keeper parts 31 which overhang the wall of the socket and engage behind the fluted head 5<SP>11</SP>. A handle 32 enables the keeper parts to be disengaged. The latch is held in its operative position by ribs 33. In a further modification, the fluted head 5 is removable to permit of the shaft passing through a small opening in the cowl. In Fig. 2, the spring 20 passes over a keeper pin 21 and its free inner end 24 rests on a bearing 22 and thus not only resists outward swinging of the arm but holds the wiper under correct pressure; it also tends to cant the socket of the end section 8 on the head 5 to produce a binding action.

Abstract: 776,254. T.-R. switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 16, 1954 [Jan. 8, 1954], No. 615/54. Class 39(1). In a T.R. cell, as described in Specification 698,896, in which one of the main electrodes has associated therewith an auxiliary priming electrode in the form of a conductor substantially completely shielded by said main electrode from the other main electrode and from said main electrode by a surrounding sleeve of vitreous material which exposes the tip of the auxiliary electrode, the auxiliary electrode incorporates a resistor which is in series with and is close to the tip thereof and serves to stabilize the priming discharge. The auxiliary electrode shown comprises a metal or alloy conductor 24, a ceramic resistor 25 and a nickel extension wire 26 to which is welded a rhodium tip 27. The conductor 24 is surrounded by a glass sheath 31 to which is seated a ceramic insulating sleeve 30 surrounding the resistor 25 and extension wire 26. A glass bead 32 is provided to locate the auxiliary electrode within the main electrode. The resistor 25 is provided with sleeves 29 which are welded to the conductor 24 and extension wire 26, or alternatively the end caps of the resistor may be welded directly thereto. In a further alternative construction the end of the extension wire 26 is coiled around one end of the resistor 25, and a short length of wire is coiled around the other end and welded to the conductor 24, the contacting portions of the wires and resistor being metallized. The glass sheath 31 may be extended to replace the ceramic sleeve 30 and may be heated where it surrounds the resistor 25 to collapse the glass on to the surface of the resistor. A resistive oxide layer may be used in place of the ceramic resistor, and in an alternative design a wire of iron-nickel cobalt alloy is sheathed with glass, the end exposed by grinding, oxidized by heating in air, and then copper plated. The copper which forms the electrode tip, is preferably oxidized on its surface to protect the resistive oxide layer from electrochemical attack by the water vapour in the fitting, which consists of argon with a trace of water vapour.

Title: Improvements in or relating to variable frequency oscillators
Inventor: MILLER ALAN
IPC: H03B5/34
Filed: 1953-01-08
Abstract: 742,656. Automatic frequency control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 11, 1953 [.Jan. 8, 1953], No. 659/53. Class 38 (4). A variable frequency oscillation generator comprises a stabilized source 5 of high frequency oscillations, having a frequency e.g. 4 Mc/s, a pulse generator 10 synchronized at a low frequency subharmonic e.g. 1 Kc/s of the stabilized frequency, a calibrated variable frequency oscillator 13 tunable over a range, e.g. 5-6 Mc/s, and a phase discriminator 11-18 for producing a control voltage depending on any phase difference between the pulses and the oscillations from the variable frequency oscillator 13 which is applied to a reactance valve circuit 17 across the tuned circuit of the oscillator 13 to lock its frequency at a harmonic of the pulse generator 10. Further, the stabilized oscillator 5 is made adjustable in frequency over a small range at least equal to the frequency of the pulses so that the feequency output of oscillator 13 may be continuous. As shown the stabilized oscillator 5 includes a crystal 1 and impedance inverting network 2-4 having a variable condenser 4 enabling the frequency to be varied on either side of the crystal series resonance frequency as described in Specification 618,967, [Group XL (b)]. The frequency of oscillator 5 may first be divided by a frequency divider 6 to 1 Mc/s, then applied to synchronize frequency dividing multivibrators 7, 8, 9 in turn to give an output pulse frequency 1 Kc/s. This output is sharpened by circuit 10 and applied, together with the oscillations from oscillator 13 fed back through a capacitor 14, to the single rectifier 11, the output pulses from which will be amplitude modulated in accordance with any phase deviation. The said pulses are then amplified and converted to saw-tooth form in an amplifier 15 and fed to a. second rectifier 16 whose output is integrated by a circuit 18-20 to form a phase dependent control voltage applied to the grid of the reactance valve 17. Due to voltage dividing resistors 18, 19 and large capacity 20 the sharp impulses arising when switch 21 is opened to lock the free running oscillator 13 are prevented from pulling the frequency beyond 1 Kc/s before locking it. The generator may be employed as a heterodyne wavemcter, e.g. for a source 22.
