  • Electric transmission mechanism and ion meter
    Patent number: 11215581
    Abstract: An electric transmission mechanism according to one aspect of the present invention may include a tubular ring fixed to a shaft electively connected to an electrode, at least one brush slidably contacting with a circumferential surface of the ring, a bearing including an inner race fixed to the ring, and a housing which is fixed to an outer race of the bearing and accommodates a contact part of the ring and the brush therein.
    Type: Grant
    Filed: April 23, 2019
    Date of Patent: January 4, 2022
    Assignee: Yokogawa Electric Corporation
    Inventors: Takeshi Kuwagata, Megumi Goto, Hikaru Shimizu, Saori Handa, Yukiko Hirano, Masaru Homma, Atsushi Otaki, Hideyuki Yagihashi
  • Turbidity measurement method and turbidimeter
    Patent number: 11073473
    Abstract: A turbidity measurement method includes irradiating a first irradiation light L1 having a first spectrum E1, detecting a first measured light ML1 based on the first irradiation light L1, irradiating a second irradiation light L2 having a second spectrum E2 different from the first spectrum E1, detecting a second measured light ML2 based on the second irradiation light L2, calculating turbidity of a liquid to be measured, and correcting at least one of a first parameter related to turbidity calculation associated with the first irradiation light L1 and a second parameter related to turbidity calculation associated with the second irradiation light L2 so that the calculated turbidity of the liquid to be measured corresponds to the turbidity of the liquid to be measured as measured using another light source serving as a standard of comparison.
