Filed: 1972-10-09
Abstract: 1356879 Welding by pressure FERRANTI Ltd 9 Oct 1972 46467/72 Addition to 1255832 Heading B3R A method of manufacturing a support for a semi-conductor device comprises the steps of providing a supply of spherical particles of gold, selecting a particle, transporting the selected particle to and depositing it on a selected part of a supporting member and impacting the particle into the surface of said selected part by an unheated impacting tool to deform the selected part and bond the particle thereto. The surface of the supporting member may be of gold, silver, copper or aluminium. An electrolytically-deposited silver coating may be provided on a nickel-iron-cobalt alloy lead frame and to protect the silver coating a gold flash of molecular thickness may be deposited thereon. Bonding may be carried in an atmosphere of nitrogen. Selection and transport of the spherical particle of gold, which may be 0À01 inch diameter, is preferably effected by means of a suction nozzle 17 which is adapted to enter a receptacle 11 holding a supply of particles 10. The nozzle is heated, e.g. to 300‹ C. and in depositing the particle 10 on the selected part of the lead frame 18 the particle 10 is deformed as in Fig. 2b and caused to adhere to the lead frame. Bonding is effected by an unheated impacting tool 20 of tungsten carbide having a polished plane end surface 21. Apparatus for simultaneously bonding gold particles to a batch of sixteen lead frames 18 mounted on an elongated strip 23 comprises a carrier 27 reciprocable laterally by cylinder and piston means 28 beneath a vertically reciprocable head 31 supporting a series of impacting tools 20 and suction nozzles 13, the carrier 27 having an undercut mounting channel 26 in and along which the strip 23 may be indexed; a series of bins 11 are provided for the particles 10 and a supply of nitrogen to the bins 11 prevents the particles becoming jammed. Semi-conductor devices, e.g. transistors 25 may subsequently be bonded to the gold-coated support areas by conventional alloying techniques to provide, e.g. a goldsilicon eutectic bond layer, and gold wire electrical interconnections 39 may be bonded to contacts on the upper face of the transistor and to the conductors 24 of the lead frame by thermocompression. The transistors are subsequently encapsulated in epoxy resin and the lead frames 18 separated from the strip 23 leaving conductors 24 extending from each epoxyencapsulated device. Where the semi-conductor device is larger, e.g. in the case of an integrated circuit a plurality of gold particles may be simultaneously bonded to the support adjacent to each other to form a single bonding area of larger size (Figs. 6, 7, not shown). In an alternative method of selection, the particles are passed over a surface having indentations at the desired locations.

Filed: 1966-10-25
Abstract: 1,195,206. Fuel material. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 12 Oct., 1967 [25 Oct., 1966], No. 47848/66. Heading G6C. A nuclear fuel body comprises an agglomeration of fuel particles each with a fission product retaining coating and maintained in adherence with one another by synthetic resin applied as an overcoating on the fission product retaining coatings. In one method of making such a fuel body, the fuel particles after having been given the fission product retaining coating are tumbled in a mixture of a carbonizable thermosetting resin in powder form and graphite powder until they acquire an outer layer of the powder. The particles are then poured into a long cylindrical mould and compressed either by means of a plunger or by vibration compaction, after which the mould is zone heated to the curing temperature of the resin, the zone moving progressively from one end of the mould to the other at such a speed as to leave cured resin behind it. Finally, the resin is carbonized. The resulting product has a uniform high density and may have a length/diameter ratio of 24/1 or more. It may be removed from its mould cavity or, in the case of graphite mould, remain in situ in the mould and be used directly as a nuclear fuel element, the graphite forming a carrier for the fuel agglomerate.

Title: Hammer flight time aligning system for impact printers
IPC: G06K15/08
Filed: 1973-10-25
Abstract: 1441007 Control of printers COMPAGNIE HONEYWELL BULL 25 Oct 1973 [26 Oct 1972] 49792/73 Heading G4H A printer incorporates means which allow for variations in the flight time t v  of individual hammers, where t v  is the interval (t 3 -t 1 ) between the time when an actuator 2 is ordered to release a hammer 3 and the time when the hammer strikes the character support. Since t v  varies uncontrollably, the "mean fictitious flight time" T = t vm +t fi  (t vm  = flight time averaged over n test "strikes", t d  = interval (t 1 -t 0 ) between the strike command and reception of hammer-actuating energy by the actuator) is made the same for all hammers by controlling t d . The test strikes are initiated by pulse DEP which sets flip-flop 82 to open gate 83 for n clock pulses H1. During each strike, H1 sets a flip-flop 15 which is reset by pulse CAR 2 to produce pulse DEL which triggers actuator 2. The duration of DEL is equal to the (uncorrected) time td and is determined by presetting counter 14 with a value PP during each strike, PP is passed to counter 13 which is incremented to its maximum by pulses UT1 from clock 85. The actuator output MART fires hammer 3 whose impact is detected (after time t v ) at 41, 42 to produce pulse IMP which resets a flip flop 51 set by the leading edge of H1. Each output TVM from 51 opens gate 52 so that pulses UT1 pass to counter 53. The accumulated counts from the n strikes are divided by n at 54 so as to produce T= t vm +t d . A reference value T R  is subtracted from T at 6 to produce an "error" signal Te=T -T R  (or its complement if Te < 0). After the nth pulse H 1 , flip flop 82 is reset and its output BIS triggers monostable 76 which outputs pulse TRANSF to open gates 72, 74. Te is transferred to counter 75 which is then decremented by pulses E (UT2) from clock 85, which pulses also pass to storage counter 14 where they are used to alter the preset value transferred to counter 13 to PP+Te (Te#0). Subsequent printing operations proceed as above, except that PPTe replaces PP whereby t d  (i.e. duration of DEL) has been modified in accordance with the monitored value of t v . Signal DEL may be divided into a "fixed delay" time DELF and a "variable delay" time DELV; a modification of Fig. 4 is described for dividing DEL and for correcting DELV (Fig. 7, not shown).

Title: Automatic deceleration control
IPC: B60T8/176
Filed: 1973-10-31
Abstract: 1429547 Automatic deceleration control GOODYEAR TIRE & RUBBER CO 31 Oct 1973 [21 Nov 1972] 50530/73 Heading F2F Vehicle deceleration is controlled by a first circuit which senses vehicular deceleration rate and produces a first electrical signal proportional thereto, which is received and compared with a preselected signal representing a required deceleration value in a second circuit the resulting signal being communicated to vehicle brake valves for controlling the application and release of brake pressure. Vehicle deceleration is detected by a decelerometer 13 providing an electrical signal which is amplified by a resistor-coupled amplifier A3, smoothed by an R-C filter circuit R13, C2, and fed to an input of a comparator A1, the other input thereof being fed from a voltage source via an adjustable resistance series R1 R2, R3 and providing the preselected desired deceleration value. If the actual deceleration is greater than the desired value, the comparator output is + 9 volts, whereas the output is -3À5 volts for the converse situation. An R-C circuit R4, C1 provides a linear ramp signal value change between these output values for smooth braking transitions, a diode CR2, and a diode CR1 coupled to resistors R5, R6, R7 limiting the signal to a voltage follower A2 (with unity gain) to minimum and maximum values for full brake application and release respectively. The follower A2 controls current drivers (via diodes CR3) of individual brake valves for the vehicle wheels. This control can be overridden by individual anti-skid circuits for each valve connected to the circuitry after the diodes CR3. To avoid an inordinate time delay for the capacitor C1 to recharge after a signal had been passed for full brake application, to prevent the possibility of skidding due to such over-application, the negative signal from the comparator A1 is passed through a diode/ resistor parallel combination CR4, R14 to an inverter 30 or comparator which produces a positive signal to a field effect transistor Q1 or similar solid-state element to prevent the capacitor C1 from discharge; this occurs after a coupled capacitor had charged (during a positive comparator output) and then discharged during the negative comparator output down to the switching threshold of the inverter 30. To prevent this situation from occurring at the initial part of the control, coupled NOR gates 32, 24 feeding the inverter 30, initially charge the capacitor C3 during an initial negative comparator output. A switch S1, either a logic or pedal travel switch, allows the automatic deceleration control to take place or causes a continuous high comparator output for full brake release. A similar switch S2 provides opportunity for manual overriding of the automatic control.
