20080199295 | SINGLE CHAIN LINEAR ACTUATOR - A linear actuator comprises a chain having adjacent first and second links. A pivotal connection pivotally connects the first link to the second link. The first link is pivotable about a pivot axis which is non-perpendicular to a longitudinal axis of the first link. A locking mechanism releasably locks the first link and the second link to prevent the first link from pivoting about the pivot axis. A releasing mechanism releases the locking mechanism to allow the first link to pivot about the pivot axis. A drive mechanism moves the chain between an extended position and a retracted position. At least a portion of the chain is helically wound when the chain is in the retracted position. | 08-21-2008 |
20080213076 | Edge grip end effector - The present invention is directed to an end effector having at least three substrate support members and at least three movable substrate gripping members. In one embodiment, an end effector has at least four substrate support members and at least three movable substrate gripping members. In another embodiment, an end effector has at least four movable substrate support members and at least three movable substrate gripping members. | 09-04-2008 |

20080292445 | WAFER CARRIER AND BUFFER SUPPORT MEMBER THEREOF - A wafer carrier is to be provided which is capable of supporting semiconductor wafers with an appropriate load weight irrespective of the number loaded therein, and preventing the semiconductor wafers from being damaged due to an impact during transportation. An inner elastic mechanism that elastically supports an inner support member applies a greater load weight to front and back end portions of the inner support member, than to a central portion thereof. Accordingly, in the case where the wafer carrier is fully loaded with the semiconductor wafers, all the wafers are supported with a uniform and appropriate load weight. On the other hand, in the case where a fewer number of semiconductor wafers are to be loaded, for example placing the semiconductor wafers in a central region, where a smaller load weight is applied by the inner elastic mechanism to the inner support member, enables applying a uniform and appropriate load weight to all of the fewer number of semiconductor wafers. | 11-27-2008 |
20080304949 | METHOD AND APPARATUS FOR HANGING A GATE - An apparatus and method for hanging a gate is provided. The apparatus includes a first leg and a second leg. The second leg is coupled to the first leg such that the first leg forms an angle with the second leg. The apparatus also includes a link. The link is coupled to at least one of the first leg and the second leg. Also, the link is adapted to be coupled to a gate. | 12-11-2008 |
20090257857 | ELECTRICAL DISTRIBUTION DEVICE ASSEMBLY - An electrical distribution device assembly includes a drawout substructure having at least first and second opposing side portions. The electrical distribution device assembly also includes a telescoping rail unit mounted to one of the first and second opposing side portions. The telescoping rail unit includes a carrier rail having a carrier rail support surface and a loading rail having a loading rail support surface. The loading rail is slidably supported by the carrier rail to define an extended deployed configuration and a retracted stowed configuration. The electrical distribution device assembly also includes an electrical device is supported upon at least one of the carrier rail and the loading rail and is selectively shiftable into and out from the drawout substructure. | 10-15-2009 |
20110002767 | MANIPULATOR HAVING A THREE-RING BEARING BETWEEN TWO OUTER PIVOT ARMS AND A PLATFORM - A handling device which has a first hearing device forming a pivot point for two inner pivot arms, to each of which one outer pivot arm is pivotally attached. The two outer pivot arms support a platform. The platform is pivotally connected to the outer pivot arms by an outer three-ring bearing. | 01-06-2011 |

20130089400 | SWING DEVICE FOR CONSTRUCTION MACHINE - A reduction gear is mounted on a revolving frame, and an electric motor having an electric motor shaft is disposed on the reduction gear. A hydraulic motor having a shaft is disposed on an upper side of the electric motor. A shaft insertion hole through which an upper end side of the electric motor shaft is inserted is provided in a lid portion of an electric motor casing. A male spline portion provided on the hydraulic motor shaft is spline-coupled to a female spline portion provided on the electric motor shaft. A bearing is provided between the shaft insertion hole and the electric motor shaft, and a pressure tight seal is provided by being located upwardly of the bearing. Hence, spline coupling portions of the female spline portion and the male spline portion are constantly lubricated by making use of drain oil which has leaked from the hydraulic motor. | 04-11-2013 |
