    摘要： A display comprises a housing having a mother board, an outer frame, and a transparent plate, and a plurality of modules each having a plurality of electron emitters arrayed on a module board. The modules are disposed as a matrix on the mother board, and sealed in vacuum in the housing. One or more spacers may be interposed between the mother board and the transparent plate to keep a gap at a predetermined distance between the mother board and the transparent plate.

    摘要： When a pulsed voltage is applied to a drive electrode, an electric field is concentrated in the vicinity of a slit, producing a field emission phenomenon. The emitted electrons are applied to a fluorescent layer when a bias voltage is applied preferably to a common electrode or a collector electrode. The fluorescent layer is excited to emit light as indicated by the arrows. Light emission devices may be arranged in a two-dimensional array, providing a field emission display.

    摘要： A drive device which does not cause breakage of a pump chamber or a seal due to thermal expansion of operation fluid is provided. A drive device 10 includes ceramic pumps 18a and 18b, which alternately pressurize and depressurize operation fluid 100 within a fluid chamber 13a on opposite sides of a movable body 110, to thereby move the movable body 110 within the flow chamber 13a. The flow chamber 13a is connected via micro flow passages 16a1 and 16b1 to an internal-pressure buffering chamber 15a, which accommodates a compressible gas. When the pressure of the operation fluid 100 is increased and decreased at high speed by the ceramic pumps, the micro flow passages exhibit a high passage resistance, so that the pressure within the channel does not escape to the internal-pressure buffering chamber 15a, and the movable body 110 moves without fail. When the pressure of the operation fluid 100 increases slowly due to expansion of the operation fluid 100, the micro flow passages exhibit a low passage resistance, so that the operation fluid 100 is led to the internal-pressure buffering chamber 15a, and the pressure increase of the operation fluid 100 is suppressed.
