  • Publication number: 20090223351
    Abstract: An electronic musical sound generator prevents a sound production sequence to be stopped from continuing to be produced even through the key is released. Even if an erroneous instruction is sent to prevent identification data from being compared, in other words, if a sound production sequence which should be stopped, continues to be produced because of failure to find the sound production sequence to be stopped, the production of the musical sound can be stopped due to the key release because a second decision block searches data in a storage block, regards a key having identification data different from the one sent as the released key, according to the sequence being produced and the key is number, and determines the sound production sequence to be stopped.

  • Patent number: 7565664
    Abstract: A method and its system for acquiring object reference information from a naming service. When executing an object, a retrieval request, which includes the object name of the object, is sent to a computer for providing the naming service. Next, the object is executed on the basis of object reference information acquired as the response to this retrieval request. Moreover, when executing the object, it is judged whether or not the object reference information on the object has been stored in a reference-information storage area into which the acquired object reference information is stored. Furthermore, if the object reference information has been stored therein, an execution request is sent which is implemented for executing the object on the basis of the stored object reference information.

  • Publication number: 20090146997
    Abstract: The present invention provides an apparatus which displays a plan wiring diagram and three-dimensional layout diagram by associating them with each other so that they can be viewed easily. A apparatus for displaying wiring includes a first storage for storing an image of a plan wiring diagram which shows parts and wirings and a second storage for storing a three-dimensional layout of an apparatus which incorporates the parts and the wirings, and a third storage for storing intermediate images transitional between a starting image in the plan wiring diagram and an ending image of a shape of the corresponding wiring in the three-dimensional layout. A processor displays the plan wiring diagram on the display device by retrieving the plan wiring diagram from the first storage based on a user's selection, and retrieves the intermediate images of a wiring from the third storage when the wiring is selected from the plan wiring diagram and displays transitions to the shape shown in the three-dimensional layout.

  • Publication number: 20090087705
    Abstract: In a reforming apparatus, for use in a fuel cell, for reforming a raw fuel into a hydrogen-rich reformed gas, a reformer generates the reformed gas from the raw fuel. A shift reactor reduces carbon monoxide contained in the reformed gas through a shift reaction. A selective oxidation unit reduces the carbon monoxide contained in the reformed gas that has passed through the shift reactor by performing selective oxidation on the carbon monoxide. A reforming reaction tube houses linearly the reformer, the shift reactor and the selective oxidation unit in this order. A combustion means produces combustion exhaust gas by combusting the raw fuel. An outer casing is placed around the reforming reaction tube, and the outer casing has a larger diameter than that of the reforming reaction tube. A heated flow passage through which the combustion exhaust gas passes to heat the reforming reaction tube is formed between the reforming reaction tube and the outer casing.

  • Publication number: 20080228492
    Abstract: A language analyzer performs speech recognition on a speech input by a speech input unit, specifies a possible word which is represented by the speech, and the score thereof, and supplies word data representing them to an agent processing unit. The agent processing unit stores process item data which defines a data acquisition process to acquire word data or the like, a discrimination process, and an input/output process, and wires or data defining transition from one process to another and giving a transition constant to the transition, and executes a flow represented generally by the process item data and the wires to thereby control devices belonging to an input/output target device group. To which process in the flow the transition takes place is determined by the weighting factor of each wire, which is determined by the connection relationship between a point where the process has proceeded and the wire, and the score of word data.

  • Patent number: 7421304
    Abstract: The pitch extracting part generates a pitch waveform signal in a manner making the time interval of the pitch of the input audio sound data to be the same. After the number of samples in each region is made to be the same by the re-sampling part, the pitch waveform signal is changed into a subband data that express a time-varying-strength of a basic frequency composition and a higher harmonic composition by the subband analyzing part. The subband data are superimposed by a modulation wave composition that expresses attaching data of an attaching object by the data attaching part and is regarded as a bit stream to output through a nonlinear quantizing. A portion expressing the higher harmonic composition that is made corresponding to the audio sound expressed by this audio sound data in the subband data are deleted by the encoding part.

  • Publication number: 20080193512
    Abstract: An astrocyte-specific drug carrier containing a retinoid derivative and/or a vitamin A analog as a constituent; a drug delivery method with the use of the same; a drug containing the same; and a therapeutic method with the use of the drug. By binding a drug carrier to a retinoid derivative such as vitamin A or a vitamin A analog or encapsulating the same in the drug carrier, a drug for therapeutic use can be delivered specifically to astrocytes. As a result, an astrocyte-related disease can be efficiently and effectively inhibited or prevented while minimizing side effects. As the drug inhibiting the activity or growth of astrocytes, for example, a siRNA against HSP47 which is a collagen-specific molecule chaperone may be encapsulated in the drug carrier. Thus, the secretion of type I to type IV collagens can be inhibited at the same time and, in its turn, fibrosis can be effectively inhibited.

  • Patent number: 7400651
    Abstract: A frequency interpolation apparatus is provided which reproduces a signal similar to an original signal by approximately recovering suppressed frequency components, from an input signal having the suppressed frequency components in a specific frequency band of the original signal. The input signal is divided into a plurality of signal component sets each having frequency components in a frequency band among a plurality of frequency bands, and a signal component set in the band with the suppressed signal components is synthesized from the plurality of divided signal component sets and added to the input signal. Each of the plurality of divided signal component sets is frequency-converted to a signal component set in the same frequency band, and the signal component set in the band with the suppressed signal components is synthesized through linear combination of the frequency-converted signal component sets.

  • Publication number: 20080109225
    Abstract: A speech piece editing section (5) retrieves speech piece data on a speech piece the read of which matches that of a speech piece in a fixed message from a speech piece database (7) and converts the speech piece so as to match the speed specified by utterance speed data. The speech piece editing section (5) predicts the prosody of a fixed message and selects an item of the retrieved speech piece data most matching each speech piece of the fixed message one by one according to the prosody prediction results. However, if the proportion of the speech piece corresponding to the selected item of the speech piece data does not reach a predetermined value, the selection is cancelled. Concerning the speech piece for which selection is not made, waveform data representing the waveform of each unit speech is supplied to a sound processing section (41). The selected speech piece data and the supplied waveform data are interconnected thereby to create data representing a synthesized speech.
