Abstract: To provide a UML design method by which architecture design pursuing optimal design parameters while viewing the overall target system on the UML model can be performed. A UML design method of the present invention is a UML design method for performing design by modeling a target system based on Unified Modeling Language (UML), using a profile storing a design parameter, the method including the steps of: storing a stereotype and a tagged value in the profile as the design parameters; annotating a UML model of the target system with the stored stereotype and tagged value; and associating the added stereotype and tagged value with each class constituting the UML model, and displaying the stereotype and tagged value and the UML model, which are associated, on a graphical user interface.

Abstract: In generation of an intonation pattern of a speech synthesis, a speech synthesis system is capable of providing a highly natural speech and capable of reproducing speech characteristics of a speaker flexibly and accurately by effectively utilizing F0 patterns of actual speech accumulated in a database. An intonation generation method generates an intonation of synthesized speech for text by estimating, based on language information of the text and based on the estimated outline of the intonation, and then selects an optimum intonation pattern from a database which stores intonation patterns of actual speech. Speech characteristics recorded in advance are reflected in an estimation of an outline of the intonation pattern and selection of a waveform element of a speech.

Abstract: A speech synthesis system making use of a pitch-synchronous waveform overlap method to realize stable speech synthesis processing in which pitch shaking is negligible. The present invention is characterized in that glottal closure instants are used as reference points (pitch marks) for overlapping. Since the glottal closure instants can be extracted stably and accurately by using dyadic Wavelet conversion, speech in which pitch shaking is negligible and rumbling sounds are minimized can be synthesized stably. In addition, more flexible waveform separation becomes possible by setting the reference point for overlapping and the reference point for waveform separation to different positions. The extraction of glottal closure instants is performed by searching the local peaks of the dyadic Wavelet conversion, but preferably a threshold value for searching for the local peaks of the dyadic Wavelet conversion is adaptively controlled each time dyadic Wavelet conversion is obtained.

Abstract: A method for recovering rhodium comprising the steps of: adding a basic compound to an organic solution containing a rhodium complex containing at least one type of organophosphorus compound as a ligand and an organophosphorus compound, combusting the resultant mixture to ash under a controlled temperature of less than 1,000.degree. C.; and cleaning the ash using a cleaning solution containing a reducing agent.

Abstract: A MIDI apparatus and a MIDI system wherein an operation ON signal for starting operation to a MIDI instrument and an operation OFF signal for stopping the operation are obtained and supplied to the MIDI instrument in response to a MIDI format signal included in a subcode signal generated during play of a record medium play apparatus. If the play state of the record medium play apparatus becomes discontinuous, such as a pause after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal is obtained, the operation OFF signal is forcedly supplied to the MIDI instrument. Thereby such the sound of the MIDI instrument is stopped when there is a discontinuous play state after the operation ON signal is supplied to the MIDI instrument and before the operation OFF signal corresponding to the operation ON signal would ordinarily be supplied.

Abstract: A device for detecting the abnormality of an optical pick-up head has a laser diode for emitting a light beam through an optical system to a reference reflective region formed at a predetermined portion of an optical disk, a photosensor for receiving a reflected light from the reflective region through the optical system, and a photosensor for detecting directly the light amount of the laser diode. The difference or a ratio of the detection signals of the photosensors is obtained, and the difference or the ratio is compared with a predetermined value. When the compared result exceeds a predetermined value, the result is decided to be an abnormality of the pick-up head.

Abstract: In an auto-focussing system, an actuator which moves together with an objective lens is vertically movable against a rotating optical disc and radiates a light beam so as to form a light spot on an information plane of the disc. A focus servo unit moves the actuator so that an optical distance between the actuator and the disc is within a proper distance region and performs the focus control of the light spot on the disc. While the actuator is approaching the optical disc, an auto-focus/focus servo controller initially makes the servo unit nonoperative and, when the actuator reaches a too-far position in a suitable servo loop distance region specified by a servo loop of the focus servo unit, the controller temporarily stops the movement of the actuator and then moves the actuator again from the too-far position by only a predetermined distance, thereby causing the actuator to be located within the focus loop distance region.

Abstract: A head drive control apparatus has a head and a scale reader. When the head is moved by a head drive mechanism, the scale reader detects the marks on a scale and converts them into a scale signal. In a speed control mode, the scale signal is compared with a target signal by an access signal generator, which produces an access signal representing the difference between the compared signals. The head is moved in accordance with the access signal until the scale signal becomes identical with the target signal. When these signals become equal, the speed control mode is switched to a position control mode. In the position control mode, a scale signal generator, a pulse generator, an up/down counter, a D/A converter, an adder and an interpolator convert the scale signal into an analog signal which represents the position of the head. The analog signal is compared with a position designating signal by a differential amplifier. The head is moved in accordance with the output signal of this amplifier.
