  • Patent number: 11146002
    Abstract: A cable assembly includes a contact ribbon made of a single stamping and including pairs of first and second signal contacts and includes a cable including pairs of first and second center conductors connected to corresponding pairs of first and second signal contacts. The contact ribbon includes a ground plane, a first row of ground contacts extending from the ground plane in a row along a first side of the ground plane such that a first line extending through the first row of ground contacts does not intersect with any signal contacts, and a second row of ground contacts extending from the ground plane in a row along a second side of the ground plane such that a second line extending through the second row of ground contacts does not intersect with any signal contacts.

  • Publication number: 20110094355
    Abstract: A combination live/dead tool holder for use on an indexing tool turret of a machine tool includes a live tool holder as well as a dead tool holder mount. The dead tool holder mount is configured to interchangeably mount to a variety of different dead tool holders. The tool holder includes a y-axis adjustment mechanism that facilitates adjustment of the position of the tool holder relative to the turret along the y axis (i.e., along a circumferential direction of the turret).

  • Patent number: 7523548
    Abstract: A process for producing a printed wiring board comprises the steps of depositing a base metal on at least one surface of an insulating film to form a base metal layer and further depositing copper or a copper alloy to form a conductive metal layer, then removing a surface metal layer, which is formed through the above step, by etching to form a wiring pattern, and then treating the base metal layer with a treating liquid capable of dissolving and/or passivating the metal that forms the base metal layer. The printed wiring board so provided comprises an insulating film and a wiring pattern formed on at least one surface of the insulating film, the wiring pattern including a base metal layer deposited on the insulating film surface and a conductive metal layer, the base metal layer for forming the wiring pattern protrudes in a widthwise direction more than the conductive metal layer for forming the wiring pattern.

  • Patent number: 4587871
    Abstract: NC turret lathe comprising a tool turret rotatable about an indexing axis and mounted for rotation in a turret slide displaceable in a direction parallel to the indexing axis, also comprising a turret indexing drive monitored by a control mechanism for rotating the tool turret, and a slide drive monitored by a control mechanism for displacing the turret slide. In order to decrease the expenditure required to index the tool turret, the slide drive also constitutes the turret indexing drive, and the slide drive control also serves to monitor the turrent indexing drive. An actuatable coupling is provided between the slide drive and the turret to prevent undesired rotation of the turret when it is only to be slidably displaced.

  • Patent number: 4182205
    Abstract: A turret type machine tool indexable to selected positions with a plurality of identical tools supported in each of the indexed positions to work on a like number of rotatable workpieces. The tool carrying turret is indexable about an axis located in the same plane as the axes of rotation of the workpieces. The turret is movable in a vertical plane between working and nonworking positions on bearings which are symmetrically disposed relative to the plane so that tool loads at the workpieces are distributed to the remainder of the machine symmetrically relative to the same common plane.

  • Patent number: 4015491
    Abstract: A horizontal shaft, to one end of which there is affixed a tool-carrying turret, is rotatably mounted in a part of the frame of the lathe. The above shaft is parallel to the axis of the spindle of the lathe, such spindle being rotatably mounted in the head stock. The shaft and the turret are reciprocated longitudinally of the axis of the shaft by a longitudinal advancing mechanism, such shaft also being rotated in steps, that is, indexed around its axis by a transverse feeding mechanism.

  • Patent number: RE29612
    Abstract: A machine tool comprising a headstock having a rotatable spindle for supporting and rotating a workpiece. A turret mounted on the headstock and offset to one side of the spindle carries tools to work upon a workpiece in the spindle. Bearing means offset to one side of the spindle supports the turret for indexing movement about and feed movement along an axis parallel to the spindle axis and second bearing means extending to one side of the spindle housing on the machine bed supports the first bearing means and the turret for movement toward and away from the spindle axis. The bed of the machine does not project substantially beyond the spindle housing in the direction of the spindle axis and the turret projects outwardly of the bed. The turret is movable along the axis of rotation thereof a variable distance depending upon the work to be performed.
