Abstract: In a method for reducing Barkhausen noise in dual stripe magnetoresistive recording heads, the topography of the bottom conductor (16) is controlled by defining the conductor sidewall angle at the edge of the track to be between 10° and 65° and preferably less than 45° from the substrate plane. Restricting the conductor sidewall profile in this manner eliminates sources of magnetic domain nucleation.

Abstract: Image data conversion processor converting a raster format of composed image data comprising line-work and picture data into a format of engraving pixel data for realizing a staggered-row screen of gravure printing cells, image density weighted for high-fidelity reproduction of tone value and line sharpness of an originally scanned image pattern. The dual-valued line-work pixels are in high resolution relative to the picture data pixels and are converted into multiple-valued line-work equivalent pixels in a picture-raster equivalent format. The multiple-valued line-work data and the picture data are assembled according to layout data operator controlled through a CRT to form the composed image data for conversion. A format converter in the processor maps the converted multiple-valued line-work equivalent pixels in the picture-raster equivalent format into gravure engraving pixels each corresponding to an engraved gravure cell of the stagger-format printing screen.

Abstract: In an apparatus for adaptively controlling an array antenna of M antenna elements, a multi-beam forming circuit calculates N beam field strengths in a known manner, and a beam selecting circuit selectively outputs beam field strengths not smaller than a predetermined threshold value by comparing the N beam field strengths with the threshold value. At least two adaptive control processors calculate N weight coefficients corresponding to N beams according to a constant modulus algorithm, respectively multiplies the calculated beam field strengths by the calculated N weight coefficients, and combines in phase respective signals of multiplication results, outputting the combined signal as a reception signal. In an initial state of one adaptive control processor, a weight coefficient thereof corresponding to the maximum beam field strength is set to a predetermined initial value not zero, and weight coefficients corresponding to the other beam field strengths are set to zero. In an initial state of the other adaptive control processor, a weight coefficient of the other adaptive control processor corresponding to at least a beam field strength having the second greater level is set to the initial value, and weight coefficients corresponding to the other beam field strengths is set to zero.

Abstract: A method and apparatus for performing dark signal correction on a photoelectric conversion device. A flow of light to the device is alternately conducted and interrupted (103). The device generates an intermixed signal (104) while the flow of light is conducted to the device, the intermixed signal including a desired signal intermixed with an unwanted dark signal. The device generates a dark signal alone (105) while the flow of light to the device is interrupted. The dark signal alone is filtered (106) to produce a filtered dark signal. The filtered dark signal is subtracted (107) from the intermixed signal to produce a corrected signal, which is representative of the desired signal.

Abstract: Digitized audio information is compressed by retrieving a first audio sample from a digitized audio signal and storing it in its entire, uncompressed, form. The next audio sample is then retrieved and a signed difference between the first audio sample value and the next audio sample value is computed. If this difference value can be represented in fewer data segments than would be required to represent the next audio sample, the difference value is stored, rather than the value of the next sample, otherwise the next sample is stored. The invention proceeds in this fashion until the entire PCM audio signal is compressed and stored. The compressed data stream is decompressed to generate an output data stream by retrieving a stored sample and examining it to ascertain whether it is a difference value or a flag which indicates that the following data represents a coded amplitude value. If the sample is a difference value it is digitally added to the previous value (taking into account the sign) and the sum is inserted into the output data stream. The sum value is retained in order to be used to compute the next output value if the following sample is also a difference value. Alternatively, if the sample is a flag value it is discarded and the next sample is retrieved and inserted into the output data stream.

Abstract: A method of halftone printing in four colors using, for cyan, magenta and black, halftone screens that will result in screening angles of 15, 45 and 75 degrees, as is the standard process in the art, and a halftone screen for yellow that will result in screening angles of 0, +60 and -60 degrees. This combination will diminish the 2 color moiré patterns that result from the interaction between the yellow and one of the other colorants. The 0 and + or - 60 degree screening angles are generated by using a screen that produces a four-centered cell having dots that are spaced to form hexagons, when the nearest neighbors of a central dot are connected by lines, as opposed to the conventional trapezoidal orientation.

Abstract: A battery charger is provided in which an output voltage and an output current are compared with a reference voltage (Vr) respectively. An error voltage is fed back, so that, in an initial charging period, constant-current charging is performed. After the battery voltage reaches a constant value, constant-voltage charging is performed. An adder (11) is provided for adding a voltage (Vg) which is proportional to a charging current of a battery (9) to the reference voltage (Vr). The added voltage output is compared with the present output voltage of the battery charger (20). The output voltage (V) of the battery charger (20) is then controlled by feeding back an error voltage (e) obtained as a result of a comparison of the added voltage output from the adder (11) with the output voltage (V) of the battery charger (20).
