Abstract: ABSTRACT     A polarized relay of this invention comprises a yoke having air gaps at four diametrically opposite positions, an H-shaped armature block having four contact pole portions positioned in the air gaps in the yoke.  The yoke comprises two yoke units, each yoke unit comprising a substantially U-shaped first magnetic plate, a permanent magnet with one of its poles being located at the middle of the lower side of the first magnetic plate, and a second magnetic plate contacted with the other pole of the permanent magnet and defining air gaps between its opposite ends and the free ends of the first magnetic plate.  The polarized relay according to this invention is featured by quick action, high sensitivity, and superior shock resistance, in that the armature block, which is a moving part, is lightweight because it does not contain the permanent magnets, and in that the magnetic efficiency is high because of the absence of the permanent magnets in the path of the magnetic flux of the magnet coil.

Abstract: ABSTRACT OF THE DISCLOSURE     An electrical permanent magnet motor gener-ator designed to operate at or near the point of theo-retical maximum energy/product of the permanent magnet without causing irreversible demagnetization thereof.  The operating point is created by enlarging the gap between the permanent magnet and core relative to the length of the permanent magnet, and results in maximizing the energy density of the magnet.  Moreover output power and power conversion efficiency are maximized by filling the gap substantially entirely with winding, thereby minimizing ohmic heat generation with respect to power output and also minimizing winding-induced and temperature sensitive demagnetizing effects while promoting linear speed-torque characteristics.  In high-speed, high-frequency applica-tions, the invention further renders low loss core mate-rials, such as magnetically soft ferrite, compatible with permanent magnets having remanent flux densities higher than the saturation flux density of the ferrite core material, so as to further maximize output power and power conversion efficiency while minimizing thermal effects.

Abstract: METHOD AND APPARATUS FOR ANALYSIS OF CORNEAL SHAPE                 Abstract of the Disclosure An analysis of the corneal shape through the com-bination of several keratometer measurements is disclosed. The eye is preferably scanned to a nasal angular position, a central angular position and a temporal angular position. The central position is straight ahead along the patient's line of sight.  The temporal and nasal positions are in the broad range of up to 5 to 22°; the intermediate range of 10 to 15°; and the narrow range of 12 to 14° on either side. Measurements in sphere, cylinder and axes are taken.  Astig-matism is in the more preferable format of 0-90° astigmatism and 45-135° astigmatism.  When each individual point is measured with its respective estimate for sphere and cylinder components, these measurements are fitted to an idealized parameter.  Then the three sets of curvature measurements taken at the specified locations are reduced to a set of adjusted, idealized curvatures all fitted to an elliptical model.  Thereafter, these fitted values create final corneal shaped parameters, the particular process here including the creation of intermediate parameters.  Finally, readings of central "k", corneal shape, apex position, cap size, vault height, corrected central "k" and goodness of fit are all set forth.

Abstract: ABSTRACT OF THE DISCLOSURE A phase-locked loop having improved off-frequency detection.  A variable frequency output signal is to be precisely locked to the frequency and phase of an alternat-ing input  signal.  This  is  accomplished by alternately utilizing two feedback loops.  A reference signal, having a frequency approximately equal to the frequency of the input signal is input to an initialization feedback loop in which it is mixed with the output signal.  The initial-ization loop produces a feedback signal for controlling a voltage controlled oscillator which generates the output signal.  An off-frequency detector detects the frequency difference between the  output signal and the reference signal.  When this frequency difference decreases below a predetermined level,  the off-frequency detector disables the initialization feedback loop and enables  a primary feedback loop.  In the primary feedback loop the phase of the output signal is compared to the phase of the input signal,  and the  difference signal controls the voltage controlled oscillator in such a manner that the phase of the output signal tracks the phase of the input signal. With this scheme,  the initialization loop,  which has a wide bandwidth, is used to control the voltage controlled oscillator over a wide range of frequencies of the output signal (i.e., the initialization loop has a broad capture range).  When the frequency of the output signal has been brought within the  capture  range  of the primary loop, operation is switched to the primary loop.  The primary loop has a narrower  bandwidth and  therefore  provides better noise rejection than the initialization loop.

Abstract: Abstract of the Disclosure An optical fiber comprises a core and cladding having different refractive indices and forming a single-mode guiding region, the guiding region being located sufficiently close to the surface of the fiber, along a selected length of the fiber, to allow coupling to a guided wave.  The outer surface of the fiber has a non-circular cross-section with a predetermined geometric relationship to the guiding region so that the location of the guiding region can be ascertained from the geometry of the outer surface.  The guiding region of the fiber preferably has a non-circular cross-section defining two transverse orthogonal axes which, in combination with the different refraction indices of the core and cladding, permits the de-coupling of waves polarized along said axes, and the non-circular cross-section of the outer surface of the fiber preferably has a predetermined geometric relationship to the transverse axes of the guiding region so that the orientation of those axes can also be ascertained from the geometry of the outer surface.  A directional coupler is formed by joining two such fibers so that at least a portion of a wave propagated through either guiding region is coupled into the other guiding region. There is also provided a method of making an optical fiber of the type described above by forming an optical preform having a core and a cladding with different refractive indices, the core being offset from the center of the preform and the outer surface of the preform having a non-circular cross-section with a predetermined geometric relationship to the core, and drawing an optical fiber from the preform with the drawing rate and temperature being controlled to produce a fiber with a cross-sectional geometry similar to that of the preform.

Abstract: ABSTRACT            In order to generate alternating current from direct current efficiently, the voltage gradient of the alternating current that is to be generated is produced by an oscillator (1) as a function of time, both directly and phase-shifted by 180 degrees.  Then each half-wave of these two voltages is compared separately in two voltage-comparison circuits (4,5) with the output voltage available at any moment, or the 180-degree phase-shifted voltage available at any moment.  Because of the two voltage-comparison circuits, in each instance one of two switches (6,7) which pass the direct current through a current-limiting impedance (8), the output of which is connected to an energy storage device (9), to the consumer, is so set that the flow of the output voltage matches the voltage flow, in that the energy storage device (9) is connected through a switch (6,7) to a positive or negative voltage, respectively, as soon as and for as long as the voltage differential on one of the two voltage comparison circuits (4,5) exceeds a prescribed positive threshold value for switching on or a prescribed negative threshold value for switching off./     (Figure 1)/
