Abstract: PROBLEM TO BE SOLVED: To provide a device with a relatively simple structure and to reduce manufacturing cost. SOLUTION: This device is composed of a negative electrode 13 formed on a first board 10 for emitting electrons, a magnet plate composed of a first region formed with multiple holes 23, realizing an actual image by converging the electrons emitted from the negative electrode 13 in the inside of the holes 23, and a second region to apply a uniform magnetic field to the holes of the first region, and a fluorescent film 33 formed on a second board 30, realizing an image by having the electrons emitted from the magnet plate collide. Holes having the same shape and interval as those of the holes of the first region are formed in the second region of a magnet plate 20.

Abstract: A method for profiling the magnetic fields of periodic permanent magnetic field structures as performed by using an electromagnetic solver to generate data fields representative of each individual magnet's contribution to the total vector potential field (110), determining the magnetization values for each magnet necessary to provide the desired total magnetic field (112) and superimposing individual vector potential fields to form a total vector potential field (113). Using the electromagnetic solver includes assuming unit magnetization for a selected magnet (120), setting the magnetization values of all of the other magnets to zero (122), setting the electromagnetic solver to use high resolution proximate the selected magnet and to use low resolution elsewhere (124), and using the electromagnetic solver to compute the vector potentials for all space for which the magnetic field is to be profiled (126). This process is repeated for each magnet of the periodic permanent magnets (128) so as to generate data files.

Abstract: The invention is a method and apparatus for facilitating frequency hopping of information in a system, without the use of a baseband hopping unit, by sharing a common TDM bus between a plurality of radio communication units, processing units, and information links. The system comprises an MSC (145) coupled to the information link (147), a common TDM bus (135, 150, 155, 140), processing units (210, 220), fixed tuned transmitters (215, 225) coupled to the fixed tuned cavity combiners (125, 130), which are coupled to the antennae (132, 134). Redundancy in the TDM buses (135, 150, 155, 140) is a mechanism for improving the fault tolerance of the system in case of TDM bus failure.

Abstract: To provide an aberration correction configuration that can realize both an aberration correction function for a long focus and an aberration correction function for a short focus. While having a conventional aberration correction apparatus configuration that has two rotationally symmetric lenses arranged between two multipole lenses, three rotationally symmetric lenses are disposed between an objective lens and a multipole lens instead of the conventional arrangement in which two rotationally symmetric lenses are disposed therebetween. When using the objective lens with a long focal length, aberrations are corrected using two rotationally symmetric lenses among three rotationally symmetric lenses disposed between the objective lens and the multipole lens. When using the objective lens with a short focal length, e.g. for high resolution observation, aberrations are corrected using two rotationally symmetric lenses of a different combination to those used for a long focus, among the three rotationally symmetric lenses disposed between the objective lens and the multipole lens. (See FIG. 3)

Abstract: A display device having a cathode for emitting electrons and a permanent magnet. A two dimensional array of channels extends between opposite poles of the magnet. The magnet generates, in each channel, a magnetic field for forming electrons from the cathode into an electron beam. An electrode grid is disposed between the cathode and the magnet for controlling flow of electrons from the cathode into each channel. A screen has a phosphor coating having a plurality of groups of adjacent pixels facing the side of the magnet remote from the cathode. Each group corresponds to a different channel. A deflector sequentially addresses the electron beam from each channel to each pixel of the corresponding group.
