  • Publication number: 20220229096
    Abstract: A power measurement apparatus includes a voltage detector, current detector, and power calculator. The voltage detector contactlessly detects an AC voltage of a conductive path to which power is supplied from an AC power source having a magnitude of AC voltage regulated to be a predetermined value, and outputs a first data signal regarding a voltage waveform of the AC voltage of the conductive path. The current detector contactlessly detects an AC current flowing through the conductive path, and outputs a second data signal regarding a current waveform of the AC current of the conductive path. A power calculator receives the first and second data signals, and calculates active power of the conductive path from a product of a second instantaneous voltage and an instantaneous current of the current waveform indicated by the second data signal. The second instantaneous voltage is generated by converting a first instantaneous voltage.

  • Patent number: 11366435
    Abstract: A control device to perform feedback control based on a current value, and output a first voltage value includes a feedforward controller using an inverse model of a plant; a feedforward voltage corrector to correct a voltage disturbance due to a modeling error between the plant and a model of the plant; a repetitive controller to learn periodic current disturbances; and a switch. The switch is ON when the current response is in a steady state, and the repetitive controller learns the disturbances and corrects a command current value. A feedback controller outputs the first voltage value by performing the feedback control based on a current value from the corrected command current value, and inputs the command current value to the inverse model to generate a second voltage value. The control device outputs a sum of the first and the second voltage value as a command voltage value.

  • Publication number: 20220024012
    Abstract: A fluid pressure hitting device comprises a piston inserted in a cylinder, a chisel, and a first, second, and third chambers. The chisel is fitted in the cylinder such that a part of the chisel projects from one axial end of the cylinder and is configured to further project from that axial end due to being hit by the piston as the piston slides toward the one axial end. The first through third chambers are partitioned by an inner peripheral surface of the cylinder and an outer peripheral surface of the piston. The first through third chambers are arranged in the axial direction in order fluid the one axial end to another axial end of the cylinder. A flow path is configured to supply fluid from a fluid supply portion when the piston hits the chisel, to the first chamber.

  • Publication number: 20210286949
    Abstract: Provided is a dialogue system where appropriate dialogue is conducted for a user when acquiring a question sentence in FAQ or the like. A key question sentence generation unit extracts one key from an answer database based on an initial key and generates a key question sentence. An output unit transmits an ask-back sentence including the key question sentence containing the one key and one or a plurality of initial keys to a user terminal. The output unit further transmits the initial key as an acquired key used for extracting the one key to the user terminal. By such processing, dialogue processing is performed by key input and an ask-back sentence in response to the key input.

  • Publication number: 20210124879
    Abstract: The dialogue system includes a ranking determination unit configured to determine a priority ranking of the resulting sentence candidates on the basis of a degree of coincidence between the input key group and the storage key group, and a presentation unit configured to present a response for prompting a user to make an additional input on the basis of a resulting sentence candidate of a highest priority ranking. In a case where there is the stored keyword which is in a predetermined correspondence relation with the character string, the keyword acquisition unit acquires the input keyword obtained by adding additional information to the stored keyword. In a case where the additional information is added to the input keyword, the ranking determination unit reduces an influence of the input keyword to which the additional information is added on the degree of coincidence.
