  • Patent number: 7728475
    Abstract: A turboalternator system includes a turboalternator having a rotatable member operatively engaged to a bearing set, a radial support element, and a contact structure engaged with the radial support element. The rotatable member defines a first end, a second end and an axis of rotation. The turboalternator system is configured to be thermally adjustable such that in a first thermal condition the contact structure is at a first radial position with respect to the axis of rotation and contacts the rotatable member to provide support, and in a second thermal condition the contact structure is at a second radial position with respect to the axis of rotation that is spaced further from the axis of rotation than the first radial position.

  • Patent number: 7728477
    Abstract: A permanent magnet rotor of a generator is used to excite a electromagnet stator to generate electric power for the generator and to control a disengagement mechanism whereby the generator can disengage from an accessory, such as a gear box drive shaft, when the generator is not working properly. The permanent magnet is affixed to an outer ball screw which normally rotates with an inner ball screw that is operatively engaged to the accessory. An increased load to the electromagnet stator slows or stops rotation of the permanent magnet rotor and outer ball screw, causing the inner ball screw to move axially from the outer ball screw and away from an accessory and toward a re-settable lock.

  • Patent number: 7728479
    Abstract: In a DC-motor according to the present invention, contact areas of first brushes can be enlarged without enlarging the external diameter of a disk on which a commutator is provided; therefore, the wear resistance of the first brushes can be enhanced while maintaining a good control-response; and at the same time, the axial dimension can be shortened dramatically, so that the DC-motor can be downsized. The first brushes 14 are radially in contact with the commutator 11, and second brushes 15 are axially in contact with slip rings 12 that are formed circumferentially inside the commutator 11.

  • Patent number: 7728513
    Abstract: It is a problem to provide an electric apparatus less in consumption power and long in life by the manufacture using the display device. An insulating bank is provided in a form surrounding the pixel portions on first electrodes over a substrate. The entire surface is applied, by a wet scheme (method), with an organic conductive film which has a thickness form of T2>T1>T3> under the influence of the insulating bank. Accordingly, the portion T3 has an increased resistance in a lateral direction, making possible to prevent against crosstalk. Due to a conductive polymer as a buffer layer, a display device can be provided which is low in drive voltage. Furthermore, because the portion T2 is increased in thickness, the electric-field concentration is relaxed at and around the pixel portion. This makes it possible to prevent the organic light-emitting element from deteriorating at around the pixel.

  • Patent number: 7728516
    Abstract: An organic EL display is constituted by providing a stress-relieving layer made of a material having a higher elastisity and a lower refractive index than an adhesive layer at edges of color-converting filters that are constituted from color filter layers alone, or color filter layers and color-converting layers, and are formed on a transparent supporting substrate. As a result, stress arising when bonding the color-converting filters and the organic light-emitting device together, or when there are changes in the environment in which the display is placed is absorbed by the stress-relieving layer, and hence the light-emitting device is not damaged, and moreover reflection at walls of the stress-relieving layer is promoted, and hence there is a reduction in the component of the light emitted by the light-emitting device that escapes sideways. An organic EL display having high reliability and high efficiency is thus provided.

  • Patent number: 7728520
    Abstract: An optoelectronic modulator is based on the concentration of an electron beam from an electron gun by a tapered cavity, which sides are photosensitive and change the electrical conductivity under the illumination of light (electromagnetic radiation). The light modulation causes the corresponding changes in the current transported across the walls of the cavity. The remaining part of the electron current exits the cavity aperture and forms an amplitude-modulated divergent electron beam.
