Publication number: 20200291956Abstract: A centrifugal pump includes an impeller and a housing defining a pump chamber that houses the impeller therein. The housing includes an inlet passage in fluid communication with the pump chamber and an outside of the housing. The inlet passage includes a connection passage part having a cylindrical shape extending from the pump chamber and a main passage part having a cylindrical shape connected to the connection passage part, so as to form a bent shape. A central axis of the main passage part is parallel to a reference plane that includes a central axis of the connection passage part. A flow direction of a fluid parallel the central axis of the main passage part is partly the same as the rotational direction of the impeller in a plan view along an axis of the impeller.Type: ApplicationFiled: March 10, 2020Publication date: September 17, 2020Applicant: AISAN KOGYO KABUSHIKI KAISHAInventors: Yoshihiko HONDA, Hironori SUZUKI, Naoki SHIRAI

Patent number: 9417123Abstract: A value of a current corresponding to a relationship between an illumination intensity instruction value and illumination intensity is calculated based on a previously obtained relationship between a current flowing through a light emitting device and the illumination intensity. A calibration table including the illumination intensity instruction value, the calculated value of the current, and the illumination intensity is created. A required illumination intensity is calculated based on exposure time per frame during autofocusing. An illumination intensity instruction value corresponding to the required illumination intensity is calculated using the calibration table. The calculated illumination intensity instruction value is set using the calibration table such that brightness of a measured image remains consistent even when a frame rate is changed.Type: GrantFiled: May 7, 2014Date of Patent: August 16, 2016Assignee: MITUTOYO CORPORATIONInventors: Hiroyuki Yoshida, Satoshi Takafuji, Naoki Shirai
