Patent number: 11939687Abstract: 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).Type: GrantFiled: February 25, 2020Date of Patent: March 26, 2024Assignee: Kogakuin UniversityInventor: Fumio Okada

Patent number: 11239715Abstract: 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.Type: GrantFiled: August 30, 2018Date of Patent: February 1, 2022Assignee: Kogakuin UniversityInventor: Mimpei Morishita
