Abstract: 1379597 Rectifier circuits; pulse modulation circuits M B TOBIAS 8 March 1973 [13 Dec 1971] 47619/71 Headings H3T H4L  In a detector circuit signal from source 18, Fig. 1, is applied over the capacitor C20 to the base of transistor T8, from the collector of which rectified output is obtained at terminal 3. Transistor T8 drives a further transistor T7 by means of the emitter circuit resistor R12, and diode D9 is back-coupled from the collector circuit of transistor T7 to the base of transistor T8. The diode D9 and transistors T7, T8 are normally conductive, going non-conductive for negative-going signals. Alternatively the resistor R12 may be omitted. The diode may be replaced by the base-emitter junction of a further transistor, the collector of which is connected, either to the supply line (Fig. 3, not shown), or to the output terminal. i.e. the collector of the input transistor (Fig. 4, not shown). In any of the circuits, a single transistor may be replaced by a compound arrangement, e.g. a Darlington circuit. Pulse width modulator.-Driving pulses are applied from terminal 35, Fig. 5, and diode D31 to the base of a transistor T30 which with transistor T29 forms a monostable circuit, being cross-coupled over resistors R26, R27 and capacitor C32, the charging circuit for which comprises the output of a detector circuit as previously described, formed by transistors T7, T8 and diode D9: the period for the unstable state is determined by the A.C. input level at terminal 1. The detector circuit may similarly be used to determine the pulse width in a freerunning multivibrator. The arrangement may also be used to determine the period in a relaxation oscillator (Fig. 6, not shown).

Abstract: 1282326 Welding by pressure WESTERN ELECTRIC CO Inc 7 Oct 1969 [8 Oct 1968] 49238/69 Heading B3R [Also in Divisions H1 and H2] Each conductor 19 of a vertical array is made able to be bonded by thermocompression to a corresponding conductor 24 in a horizontal array in a single stamping operation along a straight line (33, Fig. 7, not shown) using a thermode or heating arrangement 32 by forming each of the conductors with a parallel offset portion arranged to overlap the offset portion of the corresponding conductor in the other array. The conductors 19 are formed on a relatively low melting point, polyester film 20, each conductor 19 having an offset portion 21 at substantially 45 degrees to the remainder of the conductor. The conductors 24 are formed on a relatively high melting point substrate 25, each having a similar offset portion 26. A mask 29 of relatively high melting point material such as a polymide film and having a rectangular cut-out (30, Fig. 4, not shown) may be introduced between the two arrays to prevent excessive melting of the horizontal conductor substrate 25 and inadvertent contact of adjacent, unconnected conductors. Alternatively, this may be controlled by a choice of conductor and heater geometry. The thermode 32 was operated at 1395‹ F. with an applied pressure of 41,000 lb. per sq. inch with a bonding duration of one second and using a fairly high conductivity base fixture and heat sink clamps to control heat localization. The base fixture was permitted to pivot through an angle of less than 1 degree to improve the bonding pressure distribution.

Abstract: 1357174 Colour television SONY CORP 26 Oct 1971 [26 Oct 1970 13 April 1971] 49779/71 Heading H4F A colour demodulator for demodulating a PAL colour television signal having swinging colour bursts comprises a one line delay line 3 and a switch 2 controlled by a flip-flop 6 which is driven by line sync. pulses to operate the switch 2 at the end of each line period so that the output from terminal 2c is every second line of the input signal repeated twice due to delay line 3 and the output from terminal 2d is the invervening lines similarly repeated twice. The output from terminal 2c is fed to demodulators 13, 14 and the bursts in the outputs at terminals 2c, 2d are separated at 15, 22 and used to control flip-flop 6 so that the reference signal inputs to demodulators 13, 14 are in the correct phase to demodulate the signals from terminal 2c. The bursts separated at 15 drive a continuous wave generator circuit 18 and a local oscillator 19, the output of which is fed via phase shifters 25,26 to demodulators 13, 14 and the output of oscillator 19 is also fed via a 90 degree phase shifter 20 to a phase detector 21, which also receives the bursts separated at 22. If the switch 2 is operating as desired to produce an output at 2c having a positive R-Y modulation axis the inputs to detector 21 are in phase and the output is fed to a detecting circuit 24 which then has no effect on flip-flop 6. If however switch 2 is operating so as to produce an output at 2c having a negative R-Y modulation axis, the inputs to detector 21 are in antiphase and detecting circuit 24 causes flip-flop 6 to change state so as to produce the desired operation of switch 2. The output from generator circuit 18 is passed to a circuit 27 which feeds a colour killer 29 and an automatic colour controller 28 to control the gain of band-pass amplifier 1 to achieve colour saturation control. Hue controllers are provided at 11 and 30. In an alternative embodiment (Fig. 7, not shown) the bursts separated at 15 and 22 control continuous wave signal generators, one of which is connected directly to an adding circuit and the other of which is connected to the adding circuit via a 90 degree phase shifter. The output of the adding circuit is used to control the local oscillator and also, via detecting circuits, the mode of operation of flip-flop 6 and switch 2. The output from terminal 2d may be passed to the demodulators 13, 14 or the demodulators 13, 14 may receive inputs from different ones of outputs 2c, 2d. The PAL signal may use I and Q signals rather than colour difference signals.

Abstract: 1530139 Semiconductor data store INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1975 [23 Dec 1974 (2)] 49959/75 Heading G4C [Also in Division H3] Semiconductor memory array comprises cells each including a cross-coupled pair of FETs Q3, Q4 and a pair of load FETs Q1, Q2, and control circuits arranged when none of the cells is to be accessed to apply a first (intermediate) voltage V2 to all the row word lines, and, when any selected cell is to be accessed, to apply a second (up) voltage VI to the corresponding word line and a third (down) voltage to the remaining word lines and to all the column bit line pairs B0, B1. In the stand-by state where no cells are to be accessed signal #D is up to connect each pair of bit lines to an intermediate voltage V2 of about 3 volts via Q8, Q5, and Q6. Q8 has a limited conductance to limit the power drawn. Signal #C is up and signals #A, #B, and #E are down so that the word lines are also connected via Q12, Q12A, &c., Q9, and Q8, to voltage V2. The power drawn is limited by a feedback loop since, if the potential on a word line rises the loads Q1, Q2 become more conductive and the cells draw more power. As a result the potential at node C falls and node C is coupled back to the word line via Q9 and Q12 so that the word line potential is lowered and the power consumed falls. Information is thus retained indefinitely without refreshing and with minimum power dissipation. To access cells #A goes up to discharge the word lines via Q12 and Q11, and #B goes up to connect an up voltage VI of about 8 volts via Q10 to the bit lines which are thus charged via Q10 and Q8. #C and #D then go down to isolate the word and bit lines, the charge on the latter providing power for the cells. The selected word line is then charged by a word line decoder/driver to couple the corresponding row of cells to the bit line pairs via their loads Q1, Q2. A PRE-AMP amplifies the resulting voltage difference across the bit lines and data is read out by signals BIT 1, BIT 2 &c. which cause Q14-Q17 to conduct. To write data appropriate voltages are fed to the bit line pairs. Following a read or write operation #A and #B go down and #C, #D, and #E go up to connect the word lines via Q12, Q13, Q9, and Q8 to V2 to turn the load transistors Q1, Q2 on and refresh potentials of the bit lines and the appropriate cell nodes A or B via Q8, Q5 or Q6, and Q1 or Q2. #E then goes down and the memory is again in a stand-by state.
