  • Publication number: 20240328257
    Abstract: A downhole tool for use in a downhole drill string is provided. The downhole tool includes a rotor movably coupled within a stator, and a drive shaft movably coupled within a bearing housing. The drive shaft has a first end coupled with the rotor and a second end coupled with a drill bit. Bearing assemblies interfaces engagement between the drive shaft and the bearing housing, including polycrystalline diamond elements, each with an engagement surface, and an opposing engagement surface of a non-superhard metal.

  • Patent number: 5760405
    Abstract: An ion source for generating an ion beam of primary ions is disclosed that includes a plasma chamber and magnets positioned therein for separating the primary ions of the plasma from secondary ions within the plasma. An electrode assembly extracts the primary ions through an extractor outlet port of the plasma chamber to form an ion beam, which preferentially is shaped as a ribbon beam. The primary ions are accelerated in the form of a ribbon beam toward the target workpiece for doping the device. The magnets are oriented in the chamber to produce a uniform current density of primary ions parallel to the elongated axis of the ribbon beam.

  • Patent number: 5395356
    Abstract: Methods and apparatus are disclosed for the correction of presbyopia by reprofiling the cornea to create at least one region having a different focal point, and thereby assist the eye in accommodating for close-viewing conditions. According to the invention, at least one region of different curvature is created by photoablation of the cornea to permit the eye to accommodate for near objects. This "add" region is preferably located near the center of the optical zone and preferably within Bowman's membrane or the adjacent upper portions of the stroma, which lies directly below Bowman's membrane. Apparatus is disclosed, including a laser means and a beam-shaping means, disposed between the laser means and the surface of the cornea, which imposes a defined ablation profile upon the cornea. The system can also include a feedback control means for measuring the effectiveness of the laser during operation and for controlling the laser. The beam-shaping means can include either an aperture e.g.

  • Patent number: 4899377
    Abstract: The names in a directory stored in a personal terminal having a display are displayed as groups of names in which illustratively the first name in each group of names serves as a displayed tab which is pointed to by the user to display the respective group of names. The individual tabs are dynamically changed to conform with any change in the first name of the respective groups of names that may occur as a result of a change in the composition of the directory.

  • Patent number: 4616908
    Abstract: In the microlithographic system disclosed herein, the spaces between elements in a projection lens are filled with flowing helium gas which substantially reduces the refraction errors caused by barometric changes in the atmosphere, even though the portions of the optical path outside the lens are exposed to the atmosphere.

  • Patent number: 4477697
    Abstract: The method and apparatus encodes telephone ringing to identify both the origin and destination of a received call. The ring envelope of the ringing signal is divided into two segments. During the first segment, call origin information is encoded by varying the number of pulses or the pulse widths of a fixed frequency signal. Call destination information is encoded by time division multiplexing different frequencies into subsegments of the second segment.
