A dialkyl dialkoxycarbonylphenylphosphonate which is useful as a resin modifier, a process for producing the same in high yield at a low cost, and a process for producing a dicarboxyphenylphosphonic acid in high yield at a low cost are described.The process for producing a dialkyl dialkoxycarbonylphenylphosphonate comprises heating and reacting a dialkoxycarbonylphenyl halide with a trialkyl phosphate in the presence of a catalyst comprising an element of group VIII of the periodic table (such as an alumina supported palladium catalyst) and hydrolyzing the obtained dialkyl dialkoxycarbonylphenylphosphonate in the presence of an acid or base to produce a dicarboxyphenylphosphonic acid.

Tone color data are stored in a tone generator storage region of a RAM. The tone generator data storage region is searched upon occurrence of performance information indicative of a change of tone color, to determine whether tone color data selected by the change of tone color are stored in the tone generator data storage region, and musical tone generation is controlled such that when a result of the searching indicates that the tone color data selected by the change of tone color are stored in the tone generator data storage region, a musical tone is generated based on the tone color data, and, when the tone color data selected by the change of tone color are not stored in the tone generator data storage region, the tone color data are read out from a storage medium storing the selected tone color data, and transferred to and stored in the tone generator data storage region, while generating a musical tone based on other tone color data similar to the selected tone color data.

摘要:
Noise generated at high frequencies at the time of simultaneous switchings of logical circuits is reduced by lowering an inductance from LSI to a capacitor formed on a substrate. The capacitor is formed to ensure that an inductance from a bonding pad for the LSI loaded on the substrate to an electrode of the capacitor is 0.05 nanohenry. The lower inductance from the LSI to the capacitor allows a reduction in the amount of the noise at high frequencies among those generated in power supply system, whereby the rising time of signals is made shorter, and the speed of arithmetic operation can be increased.

The musical tone control apparatus includes at least a sensor for detecting a movement of a player and a control circuit for controlling a tone element of a musical tone to be generated based on the detected movement of the player. The sensor may be equipped within a stick or mounted at predetermined portion of the player. As the movement of the player, the sensor can detect a swinging angle of a player's arm, an acceleration applied thereto or a distance between a player's hand and a predetermined object such as a wall. As the tone element of the musical tone, the control circuit controls a tone color, a tone pitch or a tone volume of the musical tone.
摘要:
A musical-tone-control apparatus having digit members worn along the fingers and contracting and expanding in the longitudinal directions of the digit members in response to the bending and straightening of the fingers. The bending of the digit members is detected by detectors coupled to the digit members and the generation of musical tones is controlled on the basis of the detected signal, i.e. the bending of the fingers. The contraction and expansion of the digit members facilitates the bending and straightening of the fingers. The digit members can also rotate in a plane of the hand to further facilitate the movement of the fingers. The digit members are made to bend about the axes positioned on the third joint of the fingers or the second joint of the thumb (the joint just below the root of the fingers or the thumb), which makes the bending of the digit much easier. A palmar member that supports the digit members are curved to conform the shape of the palm, which makes the bending of the fingers easier as well as preventing the displacement of the palm member.

The musical tone control apparatus detects a movement of a player, such as a holding, touching, beating, depressing, pulling, lifting up or down movement. Then, the musical tone control apparatus generates musical tone control data based on a detecting result of the movement of the player. The musical tone control data control a tone pitch, a tone color or a tone volume of a musical tone to be generated.
摘要:
The present invention relates to a musical tone control apparatus which controls the generation of musical tone in response to the motion of player. By retaining holding means in a performer's hands and depressing finger pressure sensing means by a finger or fingers, signals are generated in response to the magnitude of finger pressure. When the operation signal generating means receives these signals, a pulse is generated therefrom. The beginning of the pulse is determined by associating the signals from the finger pressure sensing means with a predetermined first signal level. The ending of the pulse is determined by associating the signals from the finger pressure sending means with a predetermined second signal level, the predetermined second signal level being closer to a reference signal level which is set in releasing position than the predetermined first signal level. That is, the time interval of the pulse is determined by the characteristic of the hysteresis. Then, the musical tone control data generating means generates musical tone control data in response to the pulse. Thus, this musical tone control data is transmitted to a musical tone generating apparatus while a performer performs with vigorous movement.
