20140191456 | ACTUATOR AND CLAMP DEVICE USING SAME - A first piston for high load is inserted into a housing so as to be movable vertically, and a second piston for low load is inserted into a cylindrical hole of the first piston so as to be movable vertically. An output portion projects from the second piston to above the housing. A first spring for high load and a second spring for low load are mounted in a spring chamber defined by both pistons and. Both springs and are mounted so as to urge the first piston and the second piston upward. A switching mechanism disposed in the pressure fluid chamber at a side opposite to the spring chamber, connects the first piston selectively to the housing or the second piston. | 07-10-2014 |

20130249156 | CLAMP APPARATUS - A clamp apparatus comprises a guide member with a top wall and a circumferential wall that protrude above a housing and are inserted into a hole of a work. The guide member is inserted into the housing to be movable downward against an advancing unit that pushes the guide member upward, within a locking stroke of downward movement. Through the circumferential wall, a plurality of guide grooves are made at predetermined intervals in circumferential directions. A locking member inserted into each guide groove is biased radially inward by an annular elastic member which is a thin strip. A clamp rod has wedge surfaces engaging with the respective locking members from above, and is clamp-driven downward and unclamp-driven upward by a piston. | 09-26-2013 |

20130146158 | DIRECTIONAL CONTROL VALVE DEVICE - A first directional control valve for switching between a first supply position and a first discharge position and a second directional control valve for switching between a second discharge position and a second supply position. A first switching mechanism permits the first directional control valve to be switched to the first supply position in a state where a second switching mechanism has switched the second directional control valve to the second discharge position. In a state where the second switching mechanism has switched the second directional control valve to the second supply position, a pressure fluid supplied to the second directional control valve at the second supply position switches the first directional control valve to the first discharge position via the first switching mechanism. | 06-13-2013 |
