Abstract: In a field effect transistor, an Si layer 11, an SiC (Si1-yCy) channel layer 12, a CN gate insulating film 13 made of a carbon nitride layer (CN) and a gate electrode 14 are deposited in this order on an Si substrate 10. The thickness of the SiC channel layer 12 is set to a value that is less than or equal to the critical thickness so that a dislocation due to a strain does not occur according to the carbon content. A source region 15 and a drain region 16 are formed on opposite sides of the SiC channel layer 12, and a source electrode 17 and a drain electrode 18 are provided on the source region 15 and the drain region 16, respectively.

Abstract: In a telephony terminal apparatus for exchanging a message with the other party through a telephone line, a memory section memorizes sound data representing a sound message composed of either of a voice sound and a music sound. A selector section selects mode information effective to specify a mode of exchanging a message. A transmitter section transmits the memorized sound data to the other party together with the selected mode information, thereby enabling the other party to receive the transmitted sound data and to reproduce therefrom the sound message according to the specified mode. The selector section may select a realtime mode effective to enable the other party to receive the sound data and to process the received sound data in realtime to automatically reproduce the sound message as a ringing sound to notify a call termination.

Abstract: There is provided a tone generator system that is capable of generating various types of high-quality musical tones by means of waveform storage means with a small capacity using a tone generator based on the waveform memory method. A first waveform storage stores compressed waveform data. A decoder operates in response to tone color changing instruction data included in musical composition data to be reproduced, to read out from the first waveform storage the compressed waveform data corresponding to at least one tone color corresponding to the tone color changing instruction data and decode the readout compressed waveform data into waveform data in a pulse code modulation format. A second waveform storage stores the waveform data in the pulse code modulation format decoded by the decoder.

Abstract: In a karaoke apparatus responsive to a request for producing a karaoke accompaniment according to performance data, a sound source of a physical model type is controlled according to shape data which characterizes an acoustic vibration of a model musical instrument for electrically simulating the acoustic vibration to synthesize a tone waveform as if created by the model musical instrument, and is driven according to performance data for sequentially processing the tone waveform to produce the karaoke accompaniment. A distributor is settable with the shape data for feeding the sound source with the set physical data. A memory stores a plurality of items of performance data and a plurality of types of shape data in correspondence with each other.

Abstract: A karaoke apparatus is comprised of a data supply, a tone generator, an ADPCM decoder and a pitch shifter for sounding a requested karaoke song containing an instrumental accompaniment and a back chorus. The data supply supplies an ADPCM data representative of a phrase back chorus and being compressed by a variable compression condition, and supplies a song data containing accompaniment information prescriptive of an instrumental accompaniment, additional information prescriptive of a common back chorus and decoding information indicative of the variable compression condition of the ADPCM data, and further supplies key information which determines a pitch shift of the karaoke song. The tone generator processes the accompaniment information and the additional information to generate a first audio signal effective to sound synthesized tones of the instrumental accompaniment and the common back chorus.
