摘要:
This invention relates to a field-emission-type flat-panel display apparatus that obtains an image by causing the electrons emitted from each of electron sources arranged in matrix form to impinge upon the phosphors formed on a phosphor screen. A carbon nanotube is used as an electron source material in this flat-panel display apparatus, and the electron sources are formed by printing. The vertical sizes of the depressions and projections on the surface of each electron source which has been formed by printing are suppressed to a value equal to or less than 1 μm, preferably, equal to or less than 0.5 μm. This makes it possible to obtain a flat-panel display apparatus of stable emission characteristics.

A field strength between a control electrode in a non-aperture region and an electron emission layer is set such that an emission current between the electron emission layer and the control electrode assumes a value equal to or less than a threshold emission current density. On the other hand, a surface field strength of the electron emission layer in an aperture region is set such that, to obtain the desired brightness, an emission current between the electron emission layer and an anode becomes an operational current density.

Plural thin plate projecting portions are integrally and projectingly provided on an outer peripheral portion of a side plate member of a bobbin. Each of the thin plate projecting portions comprises a circumferential rib, a slit portion and a reinforcement rib. The circumferential rib is provided on an outer peripheral face of the thin plate projecting portion of the bobbin and then a gap is formed between a claw-shaped magnetic pole of a rotor core and the thin plate projecting portion. A varnish material etc. is caused to adhere to and harden in this gap. By filling a root portion of the claw-shape magnetic pole of the rotor core with varnish material, the resonance vibration in the rotor core can be restrained. As a result, an alternating current generator for use in a vehicle having the small magnetic noise can be obtained.

A driving force distribution/transmission device suppresses a shift of lubrication oil when a vehicle makes a turn, smoothly lubricates sliding parts, and improves reliability.The driving force distribution/transmission device 1 includes a gear input rotary member 53 and a gear output rotary member 55 that are interlocked to transmit a driving force through the meshing of a drive pinion gear 91 and a ring gear 93; and a left-right pair of clutch output adjusting mechanisms 57 and 59 coupled with both ends of the gear output rotary member 55, to carry out a driving force output adjustment through the engagement of frictional multiplate clutches 139. A closed and partitioned gear room 56 contains the drive pinion gear 91 and ring gear 93 therein. The main clutches 139 are contained in a left-right pair of closed and partitioned clutch rooms 125, respectively. Lubrication spaces in the three separate rooms, i.e., the gear room 56 and the left-right pair of clutch rooms 125 separately seal gear oil and clutch oil therein.

In an image display apparatus using an FED or an organic EL element, image display that is high in illumination uniformity and high in image quality can be performed. A display element with a matrix structure which conducts linear sequential driving which determines the luminance by a current is used, a threshold voltage of a cathode line immediately before one select period has been terminated where a control electrode line is sequentially driven is measured by a threshold voltage measuring section, the measured threshold voltage is recorded for each of the pixels, and a driving signal at the time of selecting the pixel is corrected by using the value of the recorded threshold voltage, to thereby control electric charge that is emitted from a cathode.
