Publication number: 20230258281Abstract: A valve V1 capable of detecting an operation abnormality has a magnet M1 that is attached in the vicinity of a pressing adapter 52 of a stem 53 that slides according to an opening/closing operation of the valve V1, and a magnetic sensor M2 that is attached to a surface acing the stem 53, inside the pressing adapter 52 that presses a peripheral edge of a diaphragm 51, and detects a change in a distance between the magnet M1 and the magnetic sensor M2. Further, an abnormality determination mechanism compares the change in the distance between the magnet M1 and the magnetic sensor M2 at the time of abnormality diagnosis detected by the magnetic sensor M2 and a previously measured change in the distance between the magnet M and the magnetic sensor M2 at the time of normality, and determines whether or not there is an abnormality.Type: ApplicationFiled: April 19, 2023Publication date: August 17, 2023Applicant: Fujikin IncorporatedInventors: Ryutaro Tanno, Kenji Aikawa, Akihiro Harada, Yuya Suzuki, Takahiro Matsuda, Katsunori Komehana, Masahiko Ochiishi, Tsutomu Shinohara

Patent number: 11586175Abstract: A tool is equipped with a torque sensor, suited for a tightening task of a fastening component of a device such as a fluid control system that requires a large number of fastening components for assembly and has a narrow space for access to the fastening components, and capable of automatically detecting a tightening torque. The tool includes a torque sensor capable of detecting a tightening torque for tightening a fastening component acting on a bit. The torque sensor initiates measurement of the tightening torque when the tightening torque detected exceeds a set threshold value, completes measurement when the tightening torque detected falls below the set threshold value and a set time elapses, and outputs torque-related data formed on the basis of measurement data from measurement initiation to measurement completion and including a measurement time. The torque-related data includes a peak value of the measurement data.Type: GrantFiled: December 3, 2018Date of Patent: February 21, 2023Assignees: CONNECTEC JAPAN CORPORATION, FUJIKIN INCORPORATEDInventors: Kazutoshi Horikawa, Toru Nebashi, Hidekazu Machida, Nozomi Shimoishizaka, Akihiro Harada, Masahiko Ochiishi, Yoshiaki Yamato, Hiroki Karube, Mutsunori Koyomogi, Tsutomu Shinohara
