Title: Stepped square-qam demodulator utilizing all signal points to generate control signals
Inventor: SASAKI EISAKU
IPC: H04L27/38

Abstract: "Stepped Square-QAM Demodulator Utilizing All Signal Points to Generate Control Signals"                  ABSTRACT OF THE DISCLOSURE In a stepped square QAM demodulator, each of the I- and Q-channel demodulated analog signals is supplied to an AGC and/or dc offset controller and converted to an N-bit digital signal by comparison with prescribed decision thresholds. The digital signals of outermost signal points in the stepped square phasor diagram of the SS-QAM system are converted to digital signals of signal points which form corner portions of a true square phasor diagram and the digital signals of inner signal points of the stepped square phasor diagram are converted to digital signals of corresponding signal points in the true square phasor diagram. An M-bit main data signal is derived from all of the converted digital signals (where M is smaller than N) and an auxiliary data signal is generated representing whether the M-bit main data signal represents the digital signals of the inner or outermost signal points. A first error signal representative of an error component of the M-bit main data signal and a second error signal representative of an error component of the auxiliary data signal are generated and selectively applied to a control signal generator in response to the auxiliary data signal together with the main data signal to generate a control signal for application to the AGC and/or dc offset controller.

Abstract: ANTISTATIC AND FABRIC SOFTENING LIQUID                      DETERGENT COMPOSITION            ABSTRACT OF THE DISCLOSURE:            Fabric softening and antistatic liquid detergent com-positions (softergents) are disclosed which include a narrow range ethoxylate nonionic detergent (NRE), a fabric softening and antistatic cationic compound, such as a quaternary ammonium halide, and water.  Other desirable components of such composi-tions include stilbene-type fluorescent brightener, anionic detergent, organic co-solvent, hydrotrope and lower alkanolamine.          The proportions of such components are preferably in the ranges of 10 to 35%, 2 to 15%, 0.1 to 2%, 2 to 15%, 2 to 10%, 3 to 15%, 0.3 to 3% and 40 to 60%, of NRE, quaternary ammonium halide, fluorescent brightener anionic detergent, sodium xylene sulfonate, ethanol, triethanolamine and water, respectively.  Relatively small proportions of adjuvants may also be present.        The liquid detergents are of a pH in the range of 7 to 8, clear in appearance, of a viscosity in the range of 75 to 125 centipoises, at 25°C., and of improved comparative detergency (compared to control softergents based on BRE detergents) with respect to removing oily stains from laundry, especially when such laundry is being washed at comparatively low temperatures.  The invented compositions (and wash waters containing the components) are superior in detersive action to compositions identical with them except for the replacement of the NRE with a broad range ethoxylate nonionic detergent (BRE), apparently because the presence of the NRE surprisingly counteracts the normally negative effect of quaternary ammonium halide on detergency in such compositions and under such conditions.

Title: Method of ascertaining the magnitude of forces acting upon rolls in rolling mills
Inventor: ROSENSTOCK HANS G
IPC: G01L5/00
Filed: 1988-10-28
Granted: 1993-08-24
Abstract: ABSTRACT The magnitude of forces which act upon the rolls in rolling mills can be ascertained by directly monitoring the extent of deformation of the rolls under the action of forces which are applied to the rolls in actual use of the rolling mill.  The monitoring step includes measuring the extent of deformation of each roll at a plurality of different locations.  The rolls are preferably made, at least in part of a high quality alloy known as X5 NiCrTi 25 15 which renders it possible to dispense with surface cooling of the rolls. The monitoring involves a determination of rolling force FN, of the horizontal component FH of rolling force, of the vertical component FS of rolling force, and of the angle gamma between the direction of action of the rolling force and the vertical.

Abstract: Abstract of the Disclosure A wall block set comprising frontal blocks, anchoring blocks and connecting blocks. The frontal blocks have a forward side with a texture similar to natural stone, and have dovetail projections which are integrally formed on the rear side of the frontal block.  The frontal blocks having a base width are inserted in irregular alternation.  Another type of front side has a hollow shape and therefore permits planting of foliage.  The anchoring blocks and connecting blocks form distancing elements with dovetail projections, lying opposite to one another, with the same dimension as the projections of the frontal blocks.  Through the interlacing of the frontal blocks with these anchoring and connecting blocks, double-faced dry walls of various thicknesses, as well as slope walls, which are secured on the slope by means of retainers, may be constructed.

Title: Apparatus and method for controlling electric car
Inventor: SEKIZAWA TOSHIHIKO
IPC: B60L13/03
Filed: 1989-01-05
Granted: 1995-06-20
Abstract: A PWM (pulse width modulation) inverter generat-ing an a.c. output having a variable voltage and a vari-able frequency supplies a.c. power to a linear induction motor.  An electric car supported by wheels is driven by a driving torque produced by the linear induction motor.          While the electric car is running, the motor torque varies due to various factors among which a variation of the air gap length is representative.  The power factor cos .PHI. of the PWM inverter is detected to calculate the motor torque, and the output voltage of the PWM inverter is regulated or mechanical brakes are controlled so as to compensate the torque variation.  Thus, the variation of the air gap length, which is representative of the factors giving rise to torque variations and which has been difficult to be detected, can be reliably detected to permit torque control according to the torque variation of the linear induction motor.

Abstract: ABSTRACT  (U) A novel underground guided wave antenna system ??? method.  The system comprises at least one substantially linear, electrically insulated radiating element which is buried in the earth so as to lie no more than approximately one skin depth below the earth's surface.  The effective electrical length of each radiating element is equal to at least one-third of the wavelength, as measured in the earth, of the electromagnetic signals being propagated; and the effective electrical length of a radiating element may be made greater than its actual physical length, if desired, by providing tree terminations at the ends of such radiating element.     The efficienty of the system can be increased, particu-larly when operating at high frequencies, by surrounding the radiating elements with a low loss dielectric substance, such as, for example, crushed rock.  Preferably, such dielectric substance is configured such that at least a portion of each radiating element adjacent at least one end thereof lies substantially adjacent the earth, while the remaining portions of each radiating element lie substan-tially adjacent the dielectric substance.  In addition, the gain of the system can be significantly increased, while maintaining substantially the same radiation pattern, by forming an underground array comprising a plurality of the above-described radiating elements which are positioned substan-tially parallel to one another.  Significantly, the distance between adjacent radiating elements in such an array can be as small as one-half of the skin depth in the earth of the electromagnetic signals being propagated.
