    Abstract: An emitter device (10) including a focusing array (20) with plural focusing columns (24) to focus emissions from one or more emitters (28) onto a target medium. Relative movement between the target medium and the focused emissions allows each focusing column to focus emissions over an area of the target medium encompassing the movement range. In a preferred embodiment, separate emitter, focusing array and target medium chips are used. The focusing array may be moveable, or in a particularly preferred embodiment, is affixed to the emitter chip, in which case the target medium chip is movable or the focusing array includes beam direction control.

    Abstract: The present invention comprises cyclotron display devices similar to cathode ray tubes (CRTs) in which the CRT electron gun is replaced by one or more cyclotrons that produce electrons using lower voltages and energy costs than a CRT electron gun does. This can be done both with monochrome and color displays, as disclosed. In addition, the electrons emerge from the cyclotron with adequate velocity, thus obviating the need for accelerating electrodes. The need for electron focusing is also greatly reduced, or eliminated, since the electrons emerge from the cyclotrons as beams, rather than as diffuse clouds. The cyclotron display assembly can be made to be significantly shorter than the conventional electron gun CRT. In addition, an array of cyclotrons, rather than just a single one, can be used, so that each cyclotron maps to a fractional portion of the video screen. This further shortens the length of the cyclotron display.

    Abstract: A data storage device including a substrate, a data storage layer on the substrate, and a spin-polarized electron source. The data storage layer comprises a fixed number of atomic layers of a magnetic material which provide the data storage layer with a magnetic anisotropy perpendicular to a surface of the data storage layer. A data magnetic field is created in the data storage layer. The data magnetic field is polarized either in a first direction corresponding to a first data value or in a second direction corresponding to a second data value. Data is stored in the data storage layer by providing a spin-polarized electron having an electron magnetic field with a direction of polarization corresponding to one of the first and the second data values, the electron having a wavelength 'characteristic' of unpaired electrons in the data storage layer which cause the magnetic moment of the material, and directing the spin-polarized electron at the data magnetic field to impart the direction of polarization of the electron magnetic field to the data magnetic field. Data is read from the data storage layer by directing the spin-polarized electron at a second wavelength at the data magnetic field and detecting a deflection or attraction of the spin-polarized electron by the data magnetic field. Alternatively, data is read from the data storage layer by directing the spin-polarized electron at the data magnetic field so that the magnetic medium produces a secondary electron and then detecting certain characteristics of the secondary electron.

    Abstract: A solenoïd magnetic field generating part (5) is arranged along an electron beam (0) of an electron beam unit, and a high-frequency resonator (4) for inducing cyclotron maser is provided in this part (5). High-frequency waves for inducing cyclotron maser are projected from the high-frequency resonator (4) in the same direction as, or opposite to, the travelling direction of the electron beam (0) to adjust the emittance of the electron beam (0) and to generate a high-intensity beam.
