    Abstract: A brush-less motor includes a rotor with a magnet alternately magnetized N pole and S pole in a rotating direction, and a core with plural salient poles on which coils are wound. The core faces the magnet to form a magnetic circuit. Each one of the salient poles are toothed and provided with small teeth at an edge facing the magnet. The small teeth have a pitch corresponding to two poles of the magnet. Powering to the coil responsive to a rotor position drives the rotor. This structure substantially increases volumetric efficiency of the motor.

  • Publication number: 20040245888
    Abstract: A MEMS device having a deformable mirror. In a representative embodiment, the MEMS device includes a deformable membrane supporting a plurality of light-reflecting segments that form the deformable mirror. One or more actuators, at least one of which is configured to apply torque to a side of the membrane, are used to deform the membrane. Membrane deformation causes the segments to change orientation and thereby change the shape of the minor. A representative MEMS device of the invention enables segment displacements in two directions and thereby realizes effective mirror curvature values in the range from about −2 mm−1 to about +2 mm−1.

  • Publication number: 20040245890
    Abstract: A method and apparatus are described that may be used to provide decoupled rotation of structures about different pivot points. The apparatus may include one or more fixed blades mounted to a frame or substrate, one or more movable blades mounted to each structure to be moved, and flexures on which the structures are suspended. Separate movable blades may be provided for each degree of freedom. When voltage is applied between the fixed and movable blades, the electrostatic attraction generates a force attracting movable blades toward blades that are fixed relative to the moveable blades, causing a structure to rotate about the flexures. The angle of rotation that results may be related to the size, number and spacing of the blades, the stiffness of the flexures and the magnitude of the voltage difference applied to the blades. The blades are fabricated using deep silicon etching.

    Abstract: An electron tube 10 is provided with: an MCP (electron multiplier) 14 which includes a multiplying portion 16 having a large number of microscopic holes for electron passage that can emit secondary electrons and a peripheral portion 18 that surrounds multiplying portion 16; and with a vacuum closed container 12 enclosing at least multiplying portion 16 of MCP 14. Thus, peripheral portion 18 of MCP 14 forms at least a portion of sidewalls 22 of vacuum closed container 12. Multiplying portion 16 is increased in size in this configuration in comparison with configurations having the same outer dimensions that accommodate the entirety of an MCP inside of vacuum closed container 12.

  • Publication number: 20040245928
    Abstract: A plasma display panel is provided, in which a false discharge between adjacent discharge cells is prevented, and a generation of a address discharge between a scanning electrode and a data electrode is ensured, enabling the panel to display a quality picture. An discharge cell (15) includes a recess (16) so as a dielectric layer (3) may overlap a display electrode (5); and a scanning electrode (6) and a sustain electrode (7) in which a dimension where the recess(16) overlaps the scanning electrode (6) is made larger than a dimension where the recess (16) overlaps the sustain electrode (7) An discharge area is restricted within the recess (16) for preventing a false discharge to occur between adjacent discharge cells (15), stabilizing address discharge between the scanning electrode (6) and a data electrode (11).

    Abstract: When a PDP 10 is produced by superposing, and fixing, a front plate 16 and a rear plate 18 on, and to, each other, a sheet member 20 including an X wiring layer 36 and a Y wiring layer 40 is fixed to the front plate 16 or the rear plate 18, so that X electrodes 46 and Y electrodes 48 are provided in respective discharge spaces 24. Thus, the X electrodes 46 and the Y electrodes 48 can be assembled with the front and rear plates 16, 18, by just placing the sheet member 20 between the two plates 16, 18. Therefore, in the PDP 10, the front plate 16, the rear plate 18, and the discharge electrodes 46, 48 are free of distortions resulting from a heat treatment that would otherwise be carried out to form the electrodes.

  • Publication number: 20040245933
    Abstract: Generating and frequency tuning of modulated high current electron beams and a specific efficient, high current, frequency-tunable device for generating intense radio frequency (RF), microwave electromagnetic fields in a standard rectangular waveguide. The invention utilizes current multiplication of a seed electron beam, comprising an energetic electron beam to impact a thin foil surface with high electric field. The transmissive-electron-multiplier foils also mitigate both space charge expansion and improve beam propagation effects, by shorting of the radially directed electric field at the axial location of the foil(s). Foil thinness and intensity of the exit fields provide for a multiplication process occurring in a fraction of an RF period. Both self-excited oscillator and amplifier configurations are envisaged. Also included is both a self-excited microwave generator and an amplifier, using a temporally modulated laser to generate a seed electron beam that is amplified.

  • Publication number: 20040245934
    Abstract: A reliable and efficient circuit for lighting a discharge lamp is described. An inverter accepts a direct current supply voltage and outputs an alternating current lamp voltage to drive the discharge lamp at a relatively high frequency. In one embodiment, the inverter includes semiconductor switches in a full-bridge configuration, a transformer feedback circuit to control the semiconductor switches, and a series L-C resonant circuit. In one embodiment, the inverter includes semiconductor switches in a half-bridge configuration, a transformer feedback circuit to control the semiconductor switches, and a series L-C resonant circuit. The inverter can drive multiple discharge lamps in a parallel configuration. A bypass circuit can also be coupled across a cathode of the discharge lamp to extend the life of the discharge lamp. The bypass circuit activates when a lamp cathode wears out.

  • Publication number: 20040245936
    Abstract: An integrated circuit (IC) device for driving a light emitting device, such as a laser diode, includes a heat-absorbing structure fabricated on a substrate over an electrical component, such as an output transistor, to reduce the heat transfer between the electrical component and the light emitting device. The heat-absorbing structure is designed to absorb some of the heat generated by the electrical component so that less heat from the electrical component is transferred to the light emitting device, which reduces the operating temperature of the light emitting device. A method of fabricating the IC device includes forming the electrical component on the substrate and forming the heat-absorbing structure on the substrate over the electrical component. The heat-absorbing structure may be configured to substantially encase the electrical component.
