  • Patent number: 6686595
    Abstract: An ion source configured for integration into both existing ion implanters used in semiconductor manufacturing and emerging ion implantation platforms. The ion source in accordance with the present invention includes the following features, all of which depart from the prior art to produce a well-focused, collimated and controllable ion beam. These features include: ionizing electron beams generated external to the ionization chamber, thereby extending the emitter lifetime; 90 degree magnetic deflection of electron beams such that no line-of-sight exists between the emitter and the process gas load, and the emitter is protected from bombardment by energetic charged particles; two opposed electron beams which can be operated simultaneously or separately; and use of a deceleration lens to adjust the final energy of the electron beam, substantially without affecting electron beam generation and deflection.

  • Patent number: 4496929
    Abstract: An indicating fuse is provided with an indicator at the free end of a movable spring contact, the indicator being located at an angle with respect to the plane of the spring contact. Provision is made for lower rated fusing currents utilizing the same basic fuse structure by forming a slot in the flexible spring contact at the point of maximum bending. A rounded shoulder is formed on the fuse carrier body across which the spring contact member is bent to minimize breakage and damage. The flexible spring contact is integrally formed with a U-shaped terminal that mounts it on the fuse carrier body, a second substantially identical generally U-shaped terminal also being secured to the fuse carrier body to provide a fixed contact. Molded ribs are formed in the insulating material of the fuse carrier body adjacent the open ends of the U-shaped terminal members to prevent the terminals from pinching together to form an undesired tapered configuration.

  • Patent number: 4490638
    Abstract: A unique design and construction is presented for the rotor of a dynamoelectric machine. The rotor is comprised of two end plates, bar means for holding the end plates together, a stack of pole laminations, electrical conductors wrapped about the laminations and an insulator means. The end plate contains apertures about its periphery such that the rotor can be balanced about two axis perpendicular the rotor axis of rotation by inserting masses/weights into the apertures. The insulator means electrically insulates the electrical conductors from the ends of the stack laminations, the rotor end plates and the rotor shaft. The insulator means by its unique shape further acts as a guide to position electrical conductors about the laminations during pole winding. In one embodiment the insulator means acts as a thermal insulator protecting electrical conductors when the bar means are welded to the end plates.
