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

Publication number: 20020134135Abstract: An unreacted gas detector including a reactor unit for producing a target gas by way of reacting material gases in its reaction chamber, a sensor body connected to the reactor unit, a measurement space provided in the sensor body for allowing the target gas to flow, an unreacted gas sensor having a temperature measurement section covered by a catalyst layer and disposed inside the measurement space, and a target gas sensor with its temperature measurement section disposed in the sensor body. Any unreacted gas remaining in the target gas is reacted by the catalyst layer so that a resulted temperature change is detected by the unreacted gas sensor, and a target gas temperature is measured by target gas temperature sensor, thus finding a unreacted gas concentration from a temperature difference between the temperatures obtained by the unreacted gas sensor and the target gas temperature sensor.Type: ApplicationFiled: March 13, 2002Publication date: September 26, 2002Applicant: FUJIKIN INCORPORATEDInventors: Katsunori Komehana, Yukio Minami, Akihiro Morimoto, Koji Kawada, Teruo Honiden, Osamu Nakamura, Toru Hirai, Nobukazu Ikeda
