Patent number: 10948384Abstract: A position detection switch is provided with a case having a cylindrical part that has a plurality of ribs on an inner circumferential wall thereof along the axial direction thereof. Accordingly, the strength of the case is increased and running of a molten resin for fixing a substrate disposed on the inside are improved when the molten resin is injected from a long groove of the case. The contact surface area between the ribs and a sheath is increased whereby durability against an external force and temperature variation is increased.Type: GrantFiled: September 5, 2017Date of Patent: March 16, 2021Assignee: SMC CORPORATIONInventor: Jiro Mandokoro

Patent number: 10800008Abstract: A clamp device is provided with a detection section which detects the pivotal position of a clamp arm. The detection section has: a cam section which is provided on a pivot shaft, includes a predetermined cam surface, and is formed so that the radial distance from the center of the pivot shaft to the cam surface varies circumferentially; and a proximity sensor which detects the position of the cam surface which varies as the pivot shaft pivots.Type: GrantFiled: November 18, 2015Date of Patent: October 13, 2020Assignee: SMC CORPORATIONInventors: Chiaki Fukui, Kazuyoshi Takahashi, Hideki Sasaki, Takeshi Seo, Jiro Mandokoro, Koichi Katsumata

Patent number: 10744621Abstract: A clamp device is equipped with a clamp body, a piston rod, a link mechanism, a detection mechanism for detecting a state of rotary motion of a clamp arm, and a determination unit for determining whether a state of clamping exists. The detection mechanism includes a first proximity sensor, and a knuckle joint having a first sloped surface. The determination unit, on the basis of a comparison of an output signal from the first proximity sensor to a clamp threshold value, determines whether a state of clamping exists, and on the basis of a comparison to a clamping force generation threshold value, determines whether a state of generation of clamping force exists.Type: GrantFiled: January 5, 2016Date of Patent: August 18, 2020Assignee: SMC CORPORATIONInventors: Chiaki Fukui, Kazuyoshi Takahashi, Hideki Sasaki, Takeshi Seo, Jiro Mandokoro, Koichi Katsumata

Patent number: 9696186Abstract: A position detecting sensor is mounted in a sensor attachment groove that opens on a side surface of an actuator and extends in an axial direction of the actuator. The position detecting sensor includes a housing that houses a sensor main body, and a guide member inserted into the sensor attachment groove. The guide member is of a shape such that, when the guide member is inserted into the sensor attachment groove, the guide member is required to be rotated in one direction around an axis parallel with the axis of the actuator and then rotated in a direction opposite to the one direction. After the guide member has been inserted into the sensor attachment groove, attachment thereof to the sensor attachment groove is completed by application of a fastener.Type: GrantFiled: March 19, 2015Date of Patent: July 4, 2017Assignee: SMC CORPORATIONInventor: Jiro Mandokoro

Patent number: 8955424Abstract: A linear actuator includes a cylinder main body. With respect to the cylinder main body, a slide table is disposed for reciprocal displacement through a guide mechanism, which is disposed on the cylinder main body. A stopper mechanism having a stopper bolt is disposed on one end of the slide table centrally in a widthwise direction perpendicular to the longitudinal direction of the slide table. In addition, when the slide table is displaced along the cylinder main body, an end of the stopper bolt comes into abutment with an end of a cover of the guide mechanism, whereupon the slide table becomes engaged therewith and movement of the slide table is stopped.Type: GrantFiled: December 29, 2010Date of Patent: February 17, 2015Assignee: SMC Kabushiki KaishaInventors: Koichiro Ishibashi, Seiji Takanashi, Motohiro Sato, Jiro Mandokoro, Koji Hara, Toshio Sato
