|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|
