Abstract: A method for intermingling yarn, and an air intermingling machine 1 used therein, is provided that yields yarn with the comfortable feel of hand-spun yarn, on an industrial scale. In the air intermingling machine 1, intermingling is imparted to the yarn by signals having a 1/f fluctuation, wherein the degree of intermingling of the yarn vanes with a 1/f fluctuation provides a natural, comfortable feel.

Abstract: A spinning method and a spinning frame are provided that yields spun yarn, with the comfortable feel of a hand-spun yarn, on an industrial scale. In spinning frame 1, rovings 11 are drafted with signals derived from a numerical sequence of having a 1/f fluctuation or signals derived from a melody or other sound having a 1/f fluctuation to yield a spun yarn 13 in which the diameter varies with said 1/f fluctuation, thus providing a natural, comfortable feel.

Abstract: An apparatus and a method for automatically determining the present somatic state of a human subject. The characteristic values of the subject (e.g., scalp potential, muscle potential, heart-rate, eye-movement and frequency of eye blinks, or any combination thereof) are detected and output signals corresponding to the detected characteristic values are produced, amplified and digitized. The Fourier transformation is performed on the output signals. A set of state variables for each selected frequency sub-band of a selected frequency band for each of the output signals is determined. Sets of reference weights and sets of reference biases for a neural network from sets of state reference variables corresponding to known somatic states are formed. Each of the sets of state variables, the sets of reference weights and the sets of reference biases are applied to the neural network to determine present somatic state of the subject. The present somatic state of the subject is displayed.

Abstract: A weaving method for woven goods in which the warp yarns are disposed among reed dents of uniform spacing in a reed according to a sequence of numerical values having a 1/f fluctuation, thereby imparting a 1/f fluctuation to the arrangement of warp yarns.

Abstract: A weaving method and reed where the method is practiced with the reed having spacings between dents of 1/f fluctuations resulting in a woven fabric which has a warp density of 1/f fluctuations. The spacings are established by winding yarn having a 1/f fluctuation around the dent support bars with the dents positioned between the coils of wrapped yarn.

Abstract: In order to measure the antigen-antibody reaction, a linearly polarized laser light beam is divided into first and second light beams and the first light beam is made incident upon a cell containing a reaction liquid including particles. The second light beam is phase-modulated by an optical phase-modulator with a phase-modulating angular frequency .omega..sup.0. A phase-modulated light beam emanating from the phase-modulator is made incident upon a photodetector together with light scattered by agglutinated particles via an analyzer having a polarization plane perpendicular to that of the linearly polarized light beam. An output signal of the photodetector is synchronously detected with a reference signal having a frequency of m.omega..sub.0 /2.pi., where m is a natural number.

Abstract: A coherent light beam is made incident upon a cell via a polarizer. In the cell is contained a reaction liquid consisting of fine magnetic particles having an antibody coated thereon and a sample containing an antigen which is specifically reacted with the antibody on the particles. The particles are rotated in the reaction liquid by means of alternating magnetic fields having a frequency f.sub.0 and generated by coils arranged beside the cell. Light scattered by the particles is made incident upon a photodetector via a polarizer whose polarization plane is perpendicular to that of the analyzer. An output signal from the photodetector is synchronously detected by means of a reference signal having a frequency 2f.sub.0. Then a synchronously detected output signal represents an amount of the antigen contained in the sample.

Abstract: An adaptive radar signal processor is operable to effectively suppress clutters and extract a target signal with a high degree of accuracy and includes a memory storing two-dimensional radar data corresponding to range and azimuthal directions, multipliers multiplying each of data of the same range but different azimuthal direction read out from the memory, an adder generating the added data of the multipliers as an estimated data, and a weighting coefficient determinater which determines the optimum weighting coefficients based upon the stored radar data so that the difference between the radar data and the estimated data at an observing position is minimized, and produces the difference data as a clutter-suppressed radar data.

Abstract: In an MTI radar receiver, a clutter suppressor (46, 47, 48) is switched (72), under the control of a discriminating device (71) responsive either to the shape parameter .eta. of the Weibull distribution or an average level of a clutter suppressed signal, to be selectively operable as a Weibull and a Rayleigh clutter suppressor for best possible LOG/CFAR processing with simple cell averaging circuitry. The suppressor may comprise a first processor (61) combined with an .eta. parameter calculator (48) for converting the Weibull clutter to the Rayleigh clutter, a second processor (89) for timing, and a simple suppressor (62) for the Rayleigh clutter. (FIG. 6).

Abstract: An improved electronic clinic apparatus includes a group of a number of probes positioned on or above at least one body surface of a person subjected to a clinic operation. It includes further a multichannel amplifier for amplifying electrical potential sensed at each of the probes. A multiplexer is connected with the amplifier at its output and an AD-amplifier is connected with the multiplexer at its output. An electronic computer for treatment of digital outputs from the AD-amplifier is provided. Various and several display units are provided for displaying outputs from the computer. Control means are provided between the multiplexer and the computer for successive read-out of the sensed potentials at the grouped probes and within a variable operating period, and for providing a pause period thereafter. The variable operating period added with the pause period defines a predetermined functional cycle period such as 2 ms.
