  • Patent number: 10790774
    Abstract: A drive system for an electric motor includes a first inverter that includes first switching elements, a second inverter that includes second switching elements, and a control unit that includes a first inverter control calculation section controlling on-off operation of each of the first switching elements based on a first carrier wave and a first modulation wave, a second inverter control calculation section controlling on-off operation of each of the second switching elements based on a second carrier wave and a second modulation wave, and a control synchronization section synchronizing the first carrier wave with the second carrier wave. When a sum of voltages of the first voltage source and the second voltage source is more than a voltage determination threshold, and torque of a rotating electric machine is smaller than a torque determination threshold, the control synchronization section synchronizes the first carrier wave with the second carrier wave.

  • Publication number: 20200266930
    Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

  • Publication number: 20200225631
    Abstract: Updating performance of a display screen in a terminal device that displays a screen for remotely monitoring an object to be controlled by a control device is appropriately maintained. An information device for factory automation connected to the control device that controls an object communicates with a terminal device having a display capable of displaying a screen for remotely monitoring the control device. The screen includes one or more components. The screen data for displaying the screen includes attributes of the respective components relating to the display, and a logic executed by the programmable indicator to determine the attribute values. When the terminal device displays a screen, the programmable indicator transmits the attributes and attribute values of the respective components in the screen data to the terminal device.

  • Patent number: 9667537
    Abstract: A transport system comprises a transport apparatus, which is used to construct a transport network using MPLS-TP; and a control apparatus for establishing a path in the transport network. The transport apparatus is coupled to a transfer apparatus, which is used to construct a transfer network using a network protocol different from an MPLS-TP protocol and uses the network protocol to establish a path in the transfer network in an autonomous distributed manner. The control apparatus and the transfer apparatus use the network protocol of the transfer network to transmit/receive, via the transport apparatus, control messages for controlling the transfer network. The transport apparatus avoids notifying the transfer apparatus of the fact that the control apparatus is not in a normal state, in a case where the path established in the transport network is determined as the normal state, even the control apparatus is determined as the abnormal state.
