  • Patent number: 5286911
    Abstract: An electronic rubbed-string instrument of a type which generates musical tones in response to rubbing operation of operation member across an instrument body or string in a similar way to a violin and a viola. When a part of instrument body is rubbed with an operating member, characteristics (e.g., tone color characteristics, pitch characteristics) of a musical tone to be generated are controlled in response to a speed of the operating member. Further, the characteristics of the musical tone are controlled in response to pressure applied to a part of the instrument body with the operating member. Furthermore, the characteristics of the musical tone are controlled in response to a direction in which the bow is moved across the strings.

  • Patent number: 5283386
    Abstract: A musical-tone signal controlling apparatus includes a processor which executes a musical-tone controlling process on an input musical-tone signal supplied to the processor, the processor including a delay unit which executes a delay process on the input musical-tone signal; a first discriminator which determines whether or not the input musical-tone signal to be supplied to the processor has become null; a second discriminator which determines whether or not the output musical-tone signal processed by the processor has become null; and a reset circuit which automatically resets the delay unit when the second discriminator determines that the musical-tone signal processed by the processor has become null after the first discriminator determines that the input musical-tone signal to be supplied to the processor has become null.

  • Patent number: 5283895
    Abstract: A data processing apparatus comprises input, file update, display and print processing units which are independently operated and linked to each other. Arbitrary word labels can independently be set in each processing unit. Each processing unit performs only an operation defined by the word labels. The data processed by one processing unit can be used as a source data based on which the succeeding linked processing unit performs another processing operation.

  • Patent number: 5283387
    Abstract: A single signal processor performs a pitch process which produces musical sound waveform data having a frequency corresponding to received pitch data, a filtering process for filtering the generated musical sound waveform data, and an amplitude process which controls the amplitude of a musical sound generated on the basis of the filtered musical sound waveform data in order to produce a musical sound. It simultaneously performs outputting the produced musical sound waveform data to a plurality of output terminals and an effect process which imparts an effect to the musical sound data. The signal processor outputs at least one of musical sound waveform data to which the effect is imparted and musical sound waveform data to which no effects are imparted, using at least one of an external and an internal effect circuit to thereby impart a variety of effects to the resulting musical sound.

  • Patent number: 5274798
    Abstract: In a normal state, a time counting process and a key input process are performed in accordance with an oscillation signal of 38.4 KHz generated by a crystal oscillator. In a data communication mode, a process for exchanging data with an external appliance is performed in accordance with a frequency-divided signal of the above oscillation signal and received data are stored in a memory simultaneously in a high speed process under control of an oscillation signal of 800 KHz generated by a CR oscillator. A power source circuit provides a high power source voltage, preventing all circuits from a defective operation while the high speed process is performed since the high speed process can decrease a power source voltage.

  • Patent number: 5273475
    Abstract: In a liquid crystal display panel manufacturing method, before two substrates of the display panel are adhered to each other, one of the substrates is subjected to thermal expansion, and after adhesion, the other substrate is subjected to thermal expansion so that the first and second substrates are curved, thereby obtaining a liquid crystal display panel the display surface of which is curved. The liquid crystal display panel manufactured by the above method is relatively low in cost. Further, since the two substrates are not curved forcibly, the gap therebetween is uniform over the entirety of the display surface, ensuring high display quality.

  • Patent number: 5274610
    Abstract: In an electronic reading device, the bar code of the limit time set for a question to be solved is read with a bar code reader. This limit time data is set on a sub tract timer, which decrements as time passes. The bar code reader is also designed to read the answer bar code for the question. During the limit time, answer bar codes can be read with the bar code reader. Beyond the limit time, however, those codes cannot be read. This encourages the learner to solve the questions within the limit time, enhancing the learning effects.
