  • Publication number: 20190066657
    Abstract: Provided is an audio data processing system that performs processing at high speed and obtains high-quality audio data in audio data processing using a raw audio generative model. An audio data learning apparatus of the audio data learning processing system divides full band waveform data into subband signals and performs model-learning (optimization) using the divided subband signal by a subband learning model unit. In an audio data inference apparatus, a subband learned model unit receiving at least one of an auxiliary input and subband signals performs inference processing in parallel, and a subband synthesis unit synthesizes subband signals after processing. This allows the audio data processing system to perform audio data processing using the raw audio generative at high speed.

  • Patent number: 9748065
    Abstract: A sealed contact device capable of maintaining a function for drawing a generated arc to disappear rapidly and reliably for a long period. An electromagnetic relay includes a housing, a stationary contact and a moving contact which are disposed opposite to each other in the housing, and a pair of permanent magnets and disposed opposite to the stationary contact and the moving contact. An arc generated between the stationary contact and the moving contact is drawn due to a current conducting between the stationary contact and the moving contact and magnetic forces of the permanent magnets. An arc shield member is disposed in a position in which an arc in the housing is induced.

  • Patent number: 9336965
    Abstract: The invention provides a sealed contact device capable of extinguishing an arc which extends in an arbitrary direction. The sealed contact device includes a housing; a fixed contact and a movable contact disposed in the housing in such a manner as to face each other; and permanent magnets which are disposed with the fixed contact and the movable contact interposed therebetween and which attracts an arc between the fixed contact and the movable contact using a magnetic force. An arc shielding member is disposed at a position to which the arc is attracted by current flowing between the fixed contact and the movable contact and by the magnetic force between the permanent magnets, in the housing.
