Title: Improvements in pulse distributor circuits
IPC: H04J3/04
Filed: 1949-01-07
Abstract: 659,770. Pulse circuits. LIBOIS, L. J. Jan. 7, 1949, No. 556. Convention date, Feb. 9, 1948. [Class 40 (vi)] In a circuit for producing a series of pulses each of which is progressively delayed with respect to an input pulse, the input pulse is applied to the control grid of a valve which has one output electrode connected to the input end of a delay line and the second output electrode connected to another tapping point on the line. Fig. 6 shows a circuit in which the anode of valve 2 is tapped on to the delay line at a point 12 such that the delay between the input 1 and point 12 is equal to the duration of the input pulse 3 applied to the control grid circuit. The delay line is open-circuited at the input end 1 and terminated in its characteristic impedance at the distant end so that the negative going pulse on line 10 is reflected at the input end without a change in polarity and appears back at 12 after a delay equal to twice the duration of pulse 3. A pulse 18, as shown in Fig. 5, is thus obtained at the tapping point 12 and other pulses 19, 20, 21 (Fig. 5) are obtained at further tapping points along the delay line. The pulses may be sliced between the levels 22, 23. In a modification the delay line is connected in the anode circuit of the valve and the cathode is connected to a tapping point on the line. In a further modification, Fig. 3 (not shown), the delay line is terminated in its characteristic impedance at both ends so that a sequence of double pulses as shown at 14-17 in Fig. 4 are produced.

Filed: 1921-01-07
Abstract: 156,743. Wire bounds Patents Co., (Assignees of Thompson, O. C.). July 25, 1918, [Convention date]. Angular bending; twisting wires together; shearing-adjuncts.-A machine of the general type described in Specification 156,742, for forming loops on the wires of parts to form wirebound boxes comprises combined reciprocating and transversely moving benders and loop twisting mechanisms. The loops are of such form that one may be passed through the other. Shearing-adjuncts and a one-revolution clutch are provided. The parts 7 provided with wires 5 are located against end stops 9 and an adjustable side stop 92. When the two parts are cleated at 8. supports 91 are provided under any wires 5 that are not located over cleats. The stops are carried by a rise and fall table 90 guided at 93 and normally latched in the upper position by bell-cranks 96. On the completion of the operations a guided bar 80 is depressed by cam mechanism to strip the loops from the twisters, pins 89 tripping the bell-cranks to allow the table to descend during the stripping; the parts are returned by springs. The wires are guided between the inclined ends of shear-blades and the tops of the stops 9. The movable shear-blade iscarried by and acts in advance of the vertically guided bender 20 that has an end bevelled to crowd the wire against the face of a, twister 10 carrying a pin 11. Upon retraction of the bender 20 a bender 30 forming part of the twister and having a slotted end and a swivel connection at 34 to a cam yoke is advanced to complete the formation of the loop as shown in Fig. 7. The bender 30 is also bevelled at the end to hold the wire securely in place on the twister. A clamp 40 having a yielding bevelled deflecting finger 41 is depressed to hold the wire firmly against the box part, the free end being in such relation that after twisting it remains underneath the other limb. The twister is locked in the position shown in Fig. 5 during the bending by a spring latch 15 engaging a notch in the bevel pinion 13 and during stripping in a position at right-angles by means of a second notch. The pinion is rotated by a mutilated gear segment 50 having teeth 55 for twisting, a gap 56 for the dwell during stripping, and teeth 57 for restoring the twister to the correct initial position. Cams 51, 52 retract the latch. The parts are operated by the cams and levers shown in part and the mechanisms are mounted in heads 3 adjustable along a bar 2 according to the spacing required. Each head has its own shaft 65 spur-geared to a main shaft 100 driven through a one-revolution clutch tripped by a buffer rod. The rod is retracted by a treadle, to start the machine, through a linkage including an L-shaped slot, a pin, and a deflecting cam so that the buffer-rod is restored to position to trip the clutch even though the treadle be maintained depressed.

Abstract: 534,988. Valve circuits. HAZEL'TINE CORPORATION. Jan. 15, 1940, No. 879. Convention date, Feb. 1, 1939. [Class 40 (v)] The damping of a tuned circuit is reduced by connecting it across the output of valve giving positive reaction, and the arrangement is stabilised by providing negative feed-back so proportioned as to result in the effective introduction of a negative resistance into the tuned circuit. An amplifier 10 has input terminals 11 and output terminals 12. The output circuit includes an inductance 13 coupled to an inductance 14 which is coupled by an inductance 16 to the output terminals 12. Inductance 14 comprises with condenser 15 a tuned circuit which is coupled across the output electrodes of a valve 20 by means of a resistance 21 whose inherent capacity is neutralised by an inductance 23. This provides a negative feed-back voltage while a positive feed back is provided by an inductance 24 coupled to inductance 14 and connected to the control grid of valve 20. The joint effect of the two feed-back means is to introduce a negative resistance into circuit 14, 15, the valve of which is never such as to cause instability due to changes in transconductance of the valve 20.

Filed: 1987-01-06
Abstract: PURPOSE:To enable readout at a normal voltage and to realize high-speed programming, by forming a thin epitaxial layer on a surface of a silicon substrate. CONSTITUTION:A thin film epitaxial layer 4 and N-type source and drain regions 2 and 3 are formed on a surface of a P-type silicon substrate 1. A floating gate electrode 6 is formed on the epitaxial layer 4 through a gate insulating film 5. Further, a control gate electrode 8 is disposed through a control gate insulating film 7 in order to control a potential of the floating gate electrode 6. Namely, a threshold voltage can be made about 2V which is smaller than a power source voltage 5V by forming an epitaxial layer of e.g., 10<14>atoms/cm<3> and 200Angstrom  on the surface of the silicon substrate 1. Therefore, when the quantity of electrons in the floating gate electrode 6 is not so large, conductance becomes large so as to execute readout. Further, when the concentration of the silicon substrate 1 is made higher, a width of a depletion layer region can be reduced, and so high-speed programming can be realized.
