Patent number: 10351282Abstract: A valve device includes a control device adapted to control a valve without being supplied with electricity. The control device includes at least one rotatable control cam having an outer periphery with a concave and convex shape, and a driving device adapted to rotate the control cam only in a first rotational direction, out of the first rotational direction and a second rotational direction opposite from the first rotational direction, by being supplied with a pressurized medium. The valve is placed such that a switch portion comes in contact with the outer peripheral portion of the control cam, in order that the valve is opened and closed by the control cam being rotated.Type: GrantFiled: September 15, 2017Date of Patent: July 16, 2019Assignee: FUJI IMPULSE CO.Inventors: Kazuyoshi Tarumoto, Yuichiro Kataoka

Patent number: 9650167Abstract: A sealing device is provided which is capable of a two-step holding operation with the use of a linear solenoid. The sealing device includes a stopping mechanism for stopping a movement of a movable part that forms the linear solenoid when the linear solenoid is driven at a predetermined midway point between a start point and an end point after the nozzle part has been moved from the waiting position to the stop position, and for releasing the movable part from a stop to allow the movable part to move again and reach the end point after the nozzle part has been returned from the stop position to the waiting position.Type: GrantFiled: June 20, 2012Date of Patent: May 16, 2017Assignee: Fuji Impulse Co., Ltd.Inventors: Kazukuni Yamada, Kazuyoshi Tarumoto, Yasuo Hashimoto, Junichi Kawaguchi, Suguru Akiyama

Patent number: 5501765Abstract: A heat-sealing apparatus includes a casing, a pair of lower and upper binding members for vertically binding a portion of a heat-fusible wrapper therebetween, a heater attached to a binding face of the lower binding member which is in turn fixed to the casing. The heater is operable to heat-fuse the portion of the wrapper. The apparatus further includes a switching mechanism for switching over the upper binding member between a binding position where the upper binding member is pressed against the binding face of the lower binding member and a releasing position where the upper binding member is retracted in an upper-rear direction away from the binding face of the lower binding member. The upper binding member is a heat-resistant elastic pressing roller rotatable about an axis extending along a length of the heater.Type: GrantFiled: October 4, 1994Date of Patent: March 26, 1996Assignee: Fuji Impulse Co., Ltd.Inventor: Yasuo Hashimoto
