Abstract: METHOD AND DEVICE TO PREVENT UNCONTROLLED FIRING OF          VALVE THYRISTORS         ABSTRACT OF THE DISCLOSURE    A device to prevent uncontrolled firing of valve thyristors, designed to carry out the method according to the invention for preventing uncontrolled firing of valve thyristors, and comprising an anode current monitor connected in the power circuit of a thyristor or a group of thyristors with a voltage divider placed in parallel with this thyristor or group of thyristors. The anode current monitor is connected to a timing circuit comprising a time-variable positive anode voltage bias unit whose input is electrically coupled to the center tap of the vol-tage divider, and a delay unit whose input is connected to the anode current monitor and output is connected to a second input of the time-variable positive anode voltage bias unit. The delay time of the delay unit is dependent on the amplitude and rate of drop of the anode current.          The delay unit is meant to ensure a constant positive voltage bias over a portion of a time interval, starting from an instant when the anode current drops below a speci-fied value. The output of the positive bias unit is electri-cally coupled to a circuit intended to control the thyristor or group of thyristors by means of a switch operated by a specified switching voltage.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without disconnecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at least two contact elements close enough to each other to simultaneously con-tact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resistance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: Abstract:     A semiconductor laser device has at least a laminated region of first, second, third and fourth semiconductor layers on a predetermined semiconductor substrate.  The third layer has a refractive index smaller than that of the second layer.  The first and fourth layers have a refractive index smaller than that of the second and third layers and a conductivity type opposite that of the second and third layers.  The forbidden band gap of the first and third layers is greater than that of the second semiconductor layer.  At least the second and third layers are bent so that the laser light generated inside the second layer in the proximity of the light-emitting facets generates optical coupling in the third layer and is emitted from the crystal facets of the third layer.  This device is effective for increasing output and reducing catastrophic degradation of the facets.

Abstract: ABSTRACT OF THE DISCLOSURE      A coordinate reading apparatus for reading positions on a tablet, having magnetic-field generating coils, with a magne-tic-field detector.  The magnetic-field detector produces an analog electric signal corresponding to a desired position to be read on the tablet in response to the magnetic fields in-duced by the magnetic-field generating coils.  The analog elec-tric signal generated by the detector is composed of both a fun-damental wave component signal and an n-th order harmonic wave component signal (n being an integer equal to or larger than 2).  A processing unit receives the analog electric signal from the magnetic-field detector and produces coordinate data corres-ponding to the desired position to be read on the tablet by analyzing a first rotating magnetic-field vector induced by the fundamental wave component signal and a second rotating magne-tic-field vector induced by the n-th order harmonic wave compo-nent signal.  The phase component of the fundamental wave compo-nent signal and the phase component of the n-th order harmonic wave component signal are processed so that the coordinate data can be read by the processing unit.  The apparatus of the pre-sent invention can detect coordinates at any position on a tab-let with a high degree of accuracy.

Abstract: PROPORTIONAL PLUS INTEGRAL SERVO-REVERSIBLE SPEED CONTROL                           Abstract A proportional plus integral servo-reversible speed control for use in a system driving a load in either a forward or reverse direction of travel at a desired output speed.  The servo-reversible speed control includes a control handle for providing a command voltage having a magnitude proportional to the desired output speed for travel in the reverse direction and having a magnitude inversely proportional to the desired output speed for travel in the forward direction.  A pulse pickup device and frequency to voltage converter provide a voltage proportional to the actual output speed, the actual speed voltage being applied to both an inverting and noninverting amplifier.  The actual speed voltage is applied as feedback to a proportional plus integral circuit from the noninverting amplifier for sensed travel in the reverse direction or from the inverting amplifier for sensed travel in the forward direction to provide a closed loop speed control for travel in one direction, down through zero speed and up in the opposite direction.  The proportional plus integral circuit is responsive to the command voltage and the actual speed voltage gated thereto to generate a speed control signal which maintains the output speed of the system constant.
