| 20090146356 | Swing Clamp Apparatus - A swing clamp apparatus is provided in which the clamp arm is positioned and attached to a clamp rod at a desired position in a simple and reliable manner and the clamp arm replacement workload is certainly reduced. The swing clamp apparatus comprises an attachment block fixed to the leading end of a clamp rod and to which a clamp arm is detachably attached and a pair of clamping force transmission pins inserted in the attachment block and clamp arm in the direction parallel to the orthogonal direction to the axis for coupling the positioned clamp arm to the attachment block in an integrated manner. | 06-11-2009 |
| 20090267281 | WORK POSITIONING METHOD, AND POSITIONING DEVICE - Intended is to provide a method for positioning a work ( | 10-29-2009 |
| 20100170081 | CLAMP DEVICE - A clamp device includes a first clamp head movable but restricted in movement in a perpendicular direction that is at right angles to a travel direction, and serving as a reference side, a second clamp head movable in a direction coming closer to and in a direction farther away from the first clamp head, capable of clamping a workpiece located between the first and second clamp heads, and tiltable and/or slidable in the perpendicular direction, and a drive unit driving the first and second clamp heads. The workpiece is clamped with the first and second clamp heads by moving the first and second clamp heads in a direction coming closer to each other. | 07-08-2010 |
| 20100308580 | FLUID PASSAGE CONNECTION DEVICE - A fluid passage connection device includes a positioning mechanism that incorporates a male coupler attached to a stationary base member and a female coupler attached to a movable member, and that positions the movable member with respect to the base member so that it becomes possible to connect the male and female couplers, and a clamping mechanism that drives the movable member in order to clamp and fix the movable member with respect to the base member by the elastic force of a spring, and that also releases this clamping with the hydraulic pressure of a hydraulic cylinder; and the male coupler has a connection sleeve that is driven to retract by hydraulic pressure and is driven to advance by a spring, with a hydraulic passage being provided that interconnects a hydraulic pressure operation chamber of the connection sleeve and an unclamping hydraulic chamber of the hydraulic cylinder. | 12-09-2010 |

| 20090208301 | Diamond Sintered Compact - An object is to raise both the wear resistance and chipping resistance of diamond sintered compacts while taking advantage of the characteristics of highly chipping-resistant microfine-grain diamond sintered compacts. A sintered diamond layer | 08-20-2009 |
| 20100088969 | DIAMOND SINTER - A diamond sinter which has higher hardness than conventional diamond sinters and is excellent in strength including chipping resistance and wearing resistance. The diamond sinter comprises diamond particles and a binder and is characterized in that the binder comprises: a solid solution comprising carbon, tungsten, and at least one element selected from the group consisting of titanium, zirconium, vanadium, niobium, and chromium; and an iron-group element represented by cobalt. It is further characterized in that adjacent diamond particles are bonded to each other. | 04-15-2010 |
| 20100112332 | DIAMOND SINTERED BODY AND METHOD FOR PRODUCING SAME - Provided are a diamond sintered body having higher strength and more excellent wear resistance than a conventional diamond sintered body, and a method for producing such a diamond sintered body. The diamond sintered body includes diamond particles, a binder, and a void. The diamond particles have a content of not less than 80% by volume but less than 98% by volume. The binder includes a solid solution containing at least one element selected from a group consisting of titanium, zirconium, vanadium, niobium, and chromium, carbon, and tungsten, as well as an iron group element. Neighboring ones of the diamond particles are bonded to one another. The method provides such a diamond sintered body. | 05-06-2010 |
