  • Patent number: 6516298
    Abstract: The reception terminal receives a code series from the communication path. The separator separates the code series into a speech code series and text information. The speech code series is decoded into a pitch period, a LSP coefficient, and code numerals by the synthesizer to reproduce the speech sound in the CELP system. Also, the text information is converted into pronunciation and accent information by the language analyzer and added to prosody information, such as phoneme time length and pitch pattern by the prosody generator. The LSP coefficient, and code numerals suitable for the phoneme are read from the segment database and the pitch frequency from the prosody information is inputted to the synthesizer and synthesized into speech sound.

  • Publication number: 20030016026
    Abstract: A detection unit 1 for detecting an electric field or a magnetic field is placed above a circuit board 4 to be detected. A control device 3 allows the detection unit 4 to carry out detection processes while moving the detection unit 1 in a predetermined direction with an electric current being applied to the circuit board 4 so that an electric field distribution or a magnetic field distribution on the circuit board 4 is detected. Moreover, the control device 3 compares the results of the detection with reference data that has been preliminarily registered, and if there is any portion between the two pieces of data that is not coincident with each other, it is determined that the corresponding circuit board 4 is a defective circuit board. Thus, it is possible to detect any defective portion on the printed circuit board with high precision in a non-contact state to the circuit board.

  • Patent number: 6490562
    Abstract: It is to assign proper pitch marks to voice waveforms, thereby to obtain smoothly synthesized voices and to control pitches of voices very accurately according to pitch marks of recorded messages. Any one of the fixed low-pass filters 3002-a to 3002-d is set so as to pass only fundamental component of voices and each of peak detectors 3003-a to 3003-d detects peaks and the channel selector 3004 is selected, thereby to keep taking out of peak information for fundamental waves. The channel selector 3004 decides a channel to be a correct channel if intervals of peaks detected by the peak detectors 3003-a to d are changed smoothly in the channel. According to this peak information, pitches of voices are analyzed, so that the adaptive filter 3005 passes only fundamental component of voices and the peak detector 3006 detects peaks of fundamental waves, thereby to assign pitch marks to voice waveforms.

  • Patent number: 6425819
    Abstract: In an air conditioner, filter deformation strings are disposed on an outer surface side of a bent portion of a filter, so that the bent portion of the filter is crushed when a predetermined tension is applied to the strings. When the strings are drawn, the bent portion of the filter is deformed to a plate like, and the filter can be readily removed from a casing through a filter-removable port of the casing. On the other hand, when the filter is attached into the casing, the deformed plate-like filter is inserted into the casing from the filter-removable port while drawing the strings, and thereafter, the strings are loosened so that the shape of the filter returns to an original shape.

  • Patent number: 6424937
    Abstract: According to this fundamental frequency generating method, a fundamental frequency pattern is set from a data base of a fundamental frequency pattern of each accent phrase standardized by the phoneme time length or the time length of the vowel and the vowel corresponding portion, and when the corresponding fundamental frequency pattern is not stored in the data base, the fundamental frequency pattern is generated by interpolating the interval between points serving as the references of the fundamental frequency pattern. With this method, a fundamental frequency pattern having higher naturalness than with conventional methods can be generated.

  • Publication number: 20020010732
    Abstract: The parallel processes run scheduling method, disclosed herein, reduces the overhead due to scheduling by coordinating the processing steps of the processors, not requiring explicit processor-to-processor communication. When being requested to activate or deactivate a parallel program, the parallel program manager commands the process queue managers on the processors to generate or remove the allocated process of the program. On each processor, in obedience to the command, the process queue manager enqueues or remove the process into or from the process queue. Each processor is equipped with a processes number counter to store the number of processes to run on the processor, corresponding to the number of parallel programs activated and an integrating counter that increments over time in synchronization with all other processors.

  • Patent number: 5864812
    Abstract: A method and apparatus for synthesizing speech. According to one variation of the method and apparatus, a plurality of speech segment data units is prepared for all desired speech waveforms. Speech is then synthesized by reading out from memory the appropriate speech segment data units, and a desired pitch is obtained by overlapping the appropriate speech segment data units according to a pitch period interval. According to a second variation of the method and apparatus, speech segment data units are prepared for only initial speech waveforms and first pitch waveforms, and differential waveforms. With this variation, subsequent pitch waveforms for speech synthesis are generated by combining the first pitch waveform with the corresponding differential waveform.

  • Patent number: 5779176
    Abstract: There is provided a webbing take-up device in which a load required to rotate a spool in a webbing drawing direction with reference to a shaft is stabilized in the process of rotating the spool, a stable load can be achieved with small deformation, and miniaturization can be achieved. In an ordinary state, an EA plate keeps its original shape, and the shaft and spool are rotated together with each other. When the shaft is prevented from being rotated in the webbing drawing direction in vehicle sudden deceleration, the EA plate is plastically deformed by a webbing drawing force, and the EA plate is pushed in an internal-angle portion of the spool with rotation of the spool in the webbing drawing direction with reference to the shaft. The EA plate is bent by a U-shaped portion and then wound around the outer periphery of the shaft.

  • Patent number: 5752713
    Abstract: A structurally-simple and inexpensive vehicle occupant crash protector is provided which can be miniaturized in its entirety and cope with an impact which occurs at the side of a vehicle. A folded air bag is disposed in the vicinity of a window of a vehicle. An end of the air bag in the direction in which said bag expands and moves, is pulled out by a wire retracted to a tensile device so that the air bag is expanded and a state of expansion of the air bag is held. Thus, the tensile device rapidly expands the air bag and helps the inflation thereof. Further, the end of the expanded and inflated air bag is supported by the wire retracted to the tensile device so that the expanded state of the air bag is properly held.

  • Patent number: 5692805
    Abstract: A preloader apparatus which retracts a buckle upon quick deceleration of a vehicle to tighten a webbing, and then restores the buckle to a position of ordinary vehicle running, to contemplate the improvement in operability of an operation button. The buckle is retracted upon quick deceleration of a vehicle from an ordinary protracted position to a retracted position through wires wound around a drum. After that, when a buckle-retracting force decreases and becomes smaller than a buckle-protracting force, a force F corresponding to a difference between the both acts on a projection, and the projection is broken. Although a meshing portion of a pawl meshes with an external tooth of an external gear to prevent the external gear from rotation in a direction of buckle protraction, the breakage allows the drum to rotate in the direction of buckle protraction, and the buckle can be restored to the protracted position.
