Title: Improvements in or relating to electrical logical circuits
Inventor: CLARKE RAYMOND WILLIAM
IPC: H03K19/21
Filed: 1962-01-05
Abstract: 967,980. Transistor logic circuits. MULLARD Ltd. Jan. 5. 1962, No. 534/62. Heading H3T. An " exclusive OR " circuit comprises a pair of transistors T1, T2, Fig. 1, having a coupling between their emitters, a constant current source S1 connected to each emitter, a collector load RI, R2 for each transistor, a pair of asymmetrically conducting devices D1, D2 connecting each collector to an output terminal 0, and a further constant current source S2 connected to the output terminal, and supplying a current in a direction corresponding to the forward direction of the devices D1, D2. Application of equal signals, i.e. both logical " 0's " or " 1's " to the bases A, B of both transistors causes equal currents through both transistors producing a first level of output signal at 0. Application of a " 0 " to one transistor and a " 1 " to the other cuts off one of the transistors T1 or T2 and its associated diode D1 or D2, and all the current from source S1 is transferred to the load R2 or R1 of the other producing a different level of output signal at 0. The circuit thus forms an " exclusive OR " or an equality circuit depending on the sense in which the output signal is considered. The constant current sources may comprise high resistors in series with high voltage sources, and a fixed or variable potential divider may be included in the connections between the emitters and the source S1 to balance the emitter currents of the two transistors, Figs. 3, 4 (not shown). In an alternative embodiment, Fig. 5, separate sources S1a, S1b are provided for each transistor and the two emitters are coupled by diodes D3, D4. In a further variant, these diodes may be replaced by a resistor.

Title: Improvements in or relating to character recognition devices
IPC: G06V10/88
Filed: 1965-01-06
Abstract: 1,026,896. Automatic character reading apparatus. GENERAL PRECISION Inc. Jan. 6, 1965 [Jan. 6, 1964], No. 639/65. Heading G4R. In character reading apparatus of the maskmatching type three signals are derived each representative of a different function of the match between the character and a mask and the three signals are combined to identify the character. The masks are enlarged so that, when registered with the corresponding character, there is a small margin between its outside edge to accommodate slight mis-register and skew. In the form shown, the masks 11 are mounted on a rotating disc and light is shone through the mask on to the character 18. The reflected light is received in photo-sensor 14. Because of the margin the match signal will fall to a given value and remain constant while the character is inside the mask. The constant signal is detected by differentiator C-1. Rising or falling signals cause amplifiers A-2 or A-3 to give an output and inhibit gate 20. A zero output, indicating a constant match signal allows gate 20 to pass the signal from wiper b of switch SS rotating with the mask disc. A reference signal appropriate to each mask is provided in turn by wiper b and, if gate 20 is open, it is integrated at I. The signal applied through resistor R-9 is therefore a measure of the length of time for which the match signal remained constant. The match signal is also applied to integrator I-2 which is enabled for a predetermined period in each mask period. The signal obtained is compared with a reference signal, appropriate to the corresponding mask, from wiper a and the difference representing the degree of mismatch is applied through diode D-1 if negative or through diode D-2 and inverter A-7 if positive to resistor R-14 for subtraction from the signal on resistor R-9. The match signal is also reduced by a third reference voltage from wiper d and applied to a Schmitt trigger acting as a threshold device. If the match signal at any time exceeds the appropriate reference level the trigger operates and sets a flip-flop. This signal is applied through resistor R-21 to be added to the resultant of the other two signals. Amplifier A-5 applies the final result to wiper C which selects in turn relays corresponding to the masks. The input to each relay is through an amplifier 102-110 the gain of which is set to be appropriate to the signal expected and the operating level of the relays. The resistor arrangement for adding the three signals may be replaced by multiplying means.

Filed: 1982-01-06
Abstract: PURPOSE:To prevent an accident occuring due to an unusual load which is produced in a body of a crusher by detecting a shift of a coupling which connects the body to a speed change gear. CONSTITUTION:A rotary member of a crusher 1 is operated on a driving power from a prime mover via a large gear 7, an output shaft 8 and a coupling 5, on account of which a variable thrust load is applied on a thrust bearing 11 from the rotary part 2a of the crusher body 1 via the output shaft 8. The variable thrust load is within an allowable range, however, if a solid substance may be subjected to crushing with difficulty, the resulting excessive force of the thrust load is exerted on the bearing so that the couplings 4 and 5 are forced to slide in the direction at right angles to the bearing. A cover 13 is also moved in the same direction, thereby disconnecting a projecting piece 15 from a labyrinth 12.

Title: Method and device for measuring deviation value and also for controlling seam profiling in welding
Inventor: HIKITA TOSHIHIRO
IPC: B23K26/04
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To realize a highly precise follow-up control of an energy beam for an abutting end face, in manufacturing a welded tube by emitting the energy beam to the abutting end face of a belt-like metallic sheet, by measuring on line a deviation value between the abutting end face and the energy beam. SOLUTION: With a laser head 2 moved by a prescribed distance in one of the directions crossing the moving direction of a material 1 to be welded, a first laser irradiation cicatrix is formed forcedly on the material 1. In addition, with the laser head 2 moved by the same distance in another one of the directions, a second cicatrix is formed in the same manner. The abutting end face of the material 1 is photographed by a second CCD camera 13, as are the first and the second laser irradiation cicatrices thus formed; then, the photographed image data are analyzed, so that a deviation value is measured between the abutting end face and the center of the spot of the laser beam.  The deviation value Z (i) so measured is added by an outputting part 7 to a control signal on the basis of an intersection data calculated at both end edges of a belt-like metallic sheet, so that a servo motor 8 for controlling the position of the laser head 2 is driven by means of a control signal CS (n) after the addition.

Abstract: PURPOSE: To permit the higher efficiency of electrode transducer by providing a magnetic coupler for rotor and stator at more than two places.  
     CONSTITUTION: The rotor consisting of the coil 1, the magnetic core 2, the stator to lead the magnetic energy generated in the magnetic core, and a permanent magnetic rotating according to the magnetic pole of the stator 3 is provided, and a magnetic coupler for the rotors 4 and 14 and the stator 3 is provided at more than two places 3a and 3b. Thus, static torque is shared with both the rotors 4 and 14, so that the static torque for each rotor becomes 1/2 of the conventional one. For this reason, as for the input energy, half of the conventional requisite energy is sufficient for the rotor of stator, or the current 16 as shown in the Fig. And, since the stator 3 is separated into the 3a and 3b, the starting of the rotors 4 and 14 can be performed sufficiently by applying a current two times as much as the current 16, or the same current 6 as the conventional one.
