    摘要: A musical tone synthesizing apparatus generates musical tones of acoustic musical instrument which has operator like a hammer, and a vibrating element such as a string or a vibrating plate. The apparatus has a loop circuit which comprises at least two delays of which total delay time of the two delays corresponds to pitch of a musical tone, a propagating circle for simulating the vibrating element, an exciting signal generator which generates signal in accordance with a non-linear relation between the operator and the vibrating element, and a delay controller which controls a ratio of the delay time between the two delays. By varying the ratio, the apparatus realizes the characteristics of the vibration in the vibrating elements of which struck positions by the operator change in accordance with pitch of tones to thereby generates musical tones with fidelity.

    摘要: The musical tone synthesizing apparatus simulating the musical tones of a natural musical instrument such as a piano. The apparatus contains a closed-loop circuit for simulating the vibration mechanism of the strings and a excitation circuit for generating excitation signals to the closed-loop circuit, so that the excitation circuit simulates the hammer striking the string. The apparatus also contains a scaling coefficient generating circuit for generating and supplying scaling coefficients to the excitation circuit, where the scaling coefficients represent the influence rate corresponding to the influence to be applied to the hammer by the string. In the excitation circuit, the excitation signals are multiplied by the scaling coefficients so that a slight difference of tone color is applied to the excitation signals with respect to tone pitch (or each key). For example, the scaling coefficient for comparatively lower tone pitch is set at a comparatively small value, because the hammer for lower tone pitch has relatively rounder shape and larger mass, and the felt thereof is formed relatively thicker, while the scaling coefficients for comparatively higher tone pitch is set at a comparatively large value. For this reason, the musical tone synthesizing apparatus generates a musical tone of which tone color is slightly different with respect to each tone pitch.

    摘要: An afterimage elimination circuit for a liquid crystal display apparatus provides a substantial improvement of the transient response characteristics of the liquid crystal display elements, by adding to an input video signal of the display apparatus a compensation signal, derived from that video signal, having a transient response that is determined in accordance with whether a change in the input video signal level will result in an increase or decrease of electric field strength applied to the display elements, to thereby achieve optimum compensation for both rise time and fall time response of the display elements.

    摘要: A musical tone synthesizing apparatus generates musical tones by simulating the tone generation construction of a plucked-stringed instrument or string-striking type stringed instrument. The apparatus has a closed-loop circuit which simulate a tone generating element of the instrument, an excitation circuit which creates an excitation signal corresponding to the excitation given to the tone generating element in response to the time function. The time function is set in response to operational information of the tone generating operator. The excitation signal is supplied to the closed-loop circuit and circulates around closed-loop circuit and is delayed by a delay circuit having delay interval, and is fed back into the excitation circuit as the state of the tone generating element. By displacing the excitation signal within the predetermined range of time function, the digital computation may not be in the overflow state when computing the relative displacement between the tone generating element and the tone generating operator, and thus control stability of the excitation circuit can be obtained.

    摘要: To perform, in an oscillation device compensating an output frequency based on a detection result of ambient temperature, temperature compensation of the output frequency with high accuracy. First and second quartz-crystal oscillators are structured by using a common quartz-crystal piece, and when oscillation outputs of first and second oscillation circuits respectively connected to these quartz-crystal oscillators are set to f1, f2, and oscillation frequencies of the first and the second oscillation circuits at a reference temperature are set to f1r, f2r, respectively, a frequency difference being a difference between a value corresponding to a difference between f1 and f1r and a value corresponding to a difference between f2 and f2r is treated as a temperature at that time. Further, based on the frequency difference, a frequency compensation value is determined through polynomial approximation.

    摘要: Provided is a matched filter whose circuit scale can be made significantly smaller by reducing the number of multipliers for a despreading process and the number of adders for an accumulating process. For each in-phase/orthogonal component, the matched filter includes a dual-port RAM that separates written samples into 128 groups each of 32 samples which are collectively read out group by group in order at a speed faster than a write speed in write mode, a bit separating section that separates data read group by group into 32 samples and simultaneously outputs the 32 samples, and 32 despreading/accumulating circuits that, with 16 samples sequentially input from 16 groups being taken as one block, sequentially despread individual samples, accumulate despreading results, and output accumulated values for each block. The matched filter further includes an accumulating section that accumulates absolute values for each block from in-phase/orthogonal outputs of the despreading/accumulating circuits, and outputs correlation value data.

    摘要: A non-volatile magnetic memory device is proposed, which provides sufficient magnetic shielding performance for external magnetic fields. A first magnetic shield layer 60a and a second magnetic shield layer 60b, both made of a soft magnetic metal, are formed respectively on the bottom surface of the transistor section 20, which is the mounting side of the MRAM device 10, and on the top surface of the bit line 50, which is opposite to the bottom surface of the mounting side of the MRAM device 10. On the second magnetic shield layer 60a, a passivation film 70 is formed. The magnetic flux penetrated from the external magnetic field, is suppressed below the inversion strength of the MRAM device 10, thereby improving reliability. Moreover, by using soft magnetic metal as the magnetic shield layers 60a, 60b, the magnetic shield layers can be formed by the sputtering technique, particularly composing elements can be partly shared as elements of the targets to be used for forming various layers composing the MRAM device 10 by the sputtering technique, thereby enabling to form various layers of the MRAM device 10 in a single sputtering chamber efficiently.
