  • Patent number: 6194856
    Abstract: In a controller, for use in an electric motor, which self-contains a current control system, a conducting portion of a feedback element from a current detector up to a summing point, and a conducting portion of a forward element from the summing point for the current control up to a gate terminal of each of switching devices are mounted in a power module to be hermetically encapsulated without being exposed to the external ambient atmosphere. The distributed processing is executed in the two portions, i.e., a current control loop, and a position control unit, a velocity control unit and an interface processing unit other than the current control loop. Therefore, the current control loop including the current feedback portion is constituted by another sub-microprocessor to be mounted together with the associated devices in a power module which is molded with resin such as epoxy resin.

  • Patent number: 6169670
    Abstract: An inverter apparatus operatable over an extended output frequency range having an increased upper limit with error contained in the output voltage being suppressed by eliminating dispersions of PWM pulse signals. A PWM command pulse signal and an output voltage detection signal derived from the output of the inverter are compared straightforwardly with each other for determining difference therebetween on the basis of which error contained in the inverter output voltage is canceled. An isolation device for isolating electrically a low-voltage-rated control circuitry and a high-voltage-rated main circuitry from each other is inserted between a PWM command pulse signal generating circuit and a pulse width correcting circuit.

  • Patent number: 5481664
    Abstract: For each media information element constituting a display screen image in a multimedia system, main data and attribute data are stored in a storage. After the user copies a media information element from a screen layout to another screen layout, until an attribute of the media information element is altered in either one of the layouts, the main data and/or the attribute data of the media information element is not copied in the storage of the system. Moreover, when the user varies an attribute of a media information element in one of the layouts, only attribute data of the media information element is changed in the storage. The media information includes music pieces and voices in addition to characters and graphic images.
