  • Patent number: 5340938
    Abstract: In an apparatus capable of generating a tone by a plurality of different tone generation processing modes, the respective tone generation processing modes are arbitrarily assigned in units of tone generation channels so as to efficiently utilize the tone generation channels. In particular, as one of the tone generation processing modes, a waveform readout processing such as a PCM method is used. As another processing mode, a tone generation processing mode for converting an output obtained by mixing a modulation signal in a carrier signal at an arbitrary ratio in accordance with a predetermined functional relationship to generate a tone signal is used. In this mode, when the mixing ratio is set to be a predetermined value, the tone signal has a sine or cosine wave. Various tones such as a tone including a single sine or cosine wave component, a tone including harmonic components of high orders, and the like can be widely synthesized, and can be desirably assigned to the tone generation channels.

  • Patent number: 5337346
    Abstract: In a portable telephone apparatus equipped with an electronic notebook function, a telephone operation key such as a dialing key is mounted on an upper surface of an openable/closable member mounted on an upper surface of a case body, whereas electronic notebook operation keys such as a character input key are provided at a region of a surface of the case body covered by the openable/closable member, and also at a rear surface of the openable/closable member. The portable telephone apparatus further includes a switch for detecting an opening/closing state of the openable/closable member, and a mode selecting unit for selecting a telephone mode and an electronic notebook mode in response to a detection signal derived from the detecting signal. Furthermore, a search key for searching storage data about the electronic notebook is employed on this upper surface of the openable/closable member.

  • Patent number: 5335664
    Abstract: Biological signals detected by biological signal detecting units put on a plurality of persons to be monitored are transmitted to a plurality of wristwatches. The transmitted biological signals and ID code data corresponding to the biological signals are transmitted in the form of radio signals. A receiver unit receives the biological signals and the ID code data transmitted from the wristwatches and sends them to a monitor unit. The monitor unit displays the transmitted biological signals in a one-to-one correspondence with the ID code data, Upon detecting an abnormality in a given biological signal, the monitor unit generates an alarm sound. If a corresponding person to be monitored determines that the alarm sound is erroneously generated, he or she stops the alarm sound by manipulating a switch. If the person determines that the alarm sound is not a false alarm, his or her wristwatch transmits a contact designation signal and ID code data by a radio signal.

  • Patent number: 5334860
    Abstract: An insulating substrate has thin film transistors, and scanning and data wires for supplying signals to the transistors. Each of the wires has a two-layered structure comprising a lower metal film and an upper metal film. Oxide films serving as etching stopper films and having a width smaller than each of the lower and upper metal films are interposed between the lower and upper metal films over the entire length thereof.

  • Patent number: 5331112
    Abstract: An apparatus automatically generates an additional musical part which varies as a function of a given principal part of a music piece. In an embodiment, the apparatus adds a melodic part with a varying pitch line of an arpeggio each element of which is a selected chord tone having a pitch associated with a time-shifted pitch of the principal part. As a result, a "canon" or "Fugue" polyphonic music is obtained.

  • Patent number: 5329062
    Abstract: A digital audio signal prerecorded in a DAT is processed by a computer to calculate a compressed difference data array. This compressed difference data array is obtained by compression processing on the basis of a variable compression ratio depending on the magnitude of the variation of the original waveform data array. This compressed difference data array is written in a ROM as waveform data for musical tone generation, and the ROM which stores the waveform data is used as a circuit arrangement for an electronic musical instrument. The electronic musical instrument expands the compressed difference data array on the basis of expansion ratio data, and reproduces it as a waveform data array. This waveform data array is audibly output as a musical tone signal.
