  • Patent number: 11939687
    Abstract: In an anode side electrolytic domain (130), a radial flow is formed from an outer peripheral opening (131) to an inner side opening (141) of an anode side mesh electrode (140). Flows horizontal to the electrode surface of the anode side mesh electrode 140 are formed. Gases such as ozone generated from water electrolysis in the anode side electrolytic domain (130) are dissolved in raw water in the anode side electrolytic domain (130), and anode side electrolytic water is generated. Gas such as ozone that has been atomized by the anode side mesh electrode (140) comes into contact with the raw water, and high concentration anode side electrolytic water is generated. The anode side electrolytic water generated in the anode side electrolytic domain (130) flows in the inner side opening (141) of the anode side mesh electrode (140).

  • Publication number: 20230138137
    Abstract: A control device calculates a first estimate value of a first monitored amount of a mobile object, from sensor information of a controlled object, using a transformed first model obtained by transformation of a first model having a multi-layered neural structure and activation functions of a ReLU structure, and predicting dynamic behavior of the mobile object. The transformed first model is a model for which weight coefficients, biases, and upper and lower limit values of input/output variables of neurons are set based on the first model and in which activation functions of the neurons are transformed using a linear inequality function having a binary variable. The control device calculates a second estimate value of a second monitored amount of the controlled object from a candidate value of an operation amount for controlling the second monitored amount.

  • Patent number: 11239715
    Abstract: In an electric motor, three-phase coils are provided to an armature disposed between an outside field system and an inside field system, and Halbach arrays are employed in the outside field system and the inside field system. Each of the Halbach arrays is divided by a number of divisions that is any number computed by adding two to a multiple of three. Permanent magnets are arrayed such that their magnetization directions are changed in sequence by steps of an angle computed by dividing one cycle's worth of electric angle by the number of divisions. Torque ripple is thereby suppressed in the electric motor.
