A graphic fluorescent display device is disclosed which is capable of effectively eliminating a streak pattern occurring right below cathodes. The fluorescent display device is constructed in such a manner that an electric field controlling electrode is disposed on the surface of a cover plate opposite to a substrate having anodes formed thereon, and potential positive with respect to the cathodes is applied to the electric field controlling electrode so that electrons emitted from the cathodes may be diffused by the positive electric field of the electric field controlling electrode.

A computer peripheral apparatus of this invention has a check step of checking whether received data is infected with a computer virus. If the received data satisfies a predetermined condition, the apparatus executes the check step before predetermined data processing. If the received data does not satisfy the predetermined condition, the apparatus executes the check step before the predetermined data processing.

In an electron tube including vibration absorbers for linear members such as filaments, a vibration absorbing means that is made of a vibration absorber with a large vibration absorption effect, has a simple configuration, and is attachable easily to filaments is provided. The vibration absorbing means is formed of a holder 231, a vibration absorber 241, and a getter shielding member 251. These three members are attached to a shielding electrode S overlying the front substrate 111 to dispose the vibration absorber 241 between the holder 231 and getter shielding member 251. The vibration absorber 241 is mounted to slide or rotate between the holder 231 and the getter shielding member 251. The vibration absorber 241 has an aperture 2413 in which the filament is engaged. The bottom (apex) of the aperture 2413 is formed eccentrically. The vibration absorber 241 is in line contact with the shielding electrode S, as shown in FIG. 3(c).

A printer head capable of increasing intensity of dot-like light irradiated onto a record medium without requiring to increase a drive voltage or the number of printer heads arranged. The optical printer head includes a luminous element including two luminous dot arrays arranged in parallel to each other at a predetermined interval in a sub-scanning direction. The luminous dot arrays each are constituted of a plurality of luminous dots which have a dimension in the sub-scanning direction increased by a predetermined magnification as compared with that in a main scanning direction and are spaced from each other at identical intervals in the main scanning direction. The luminous dots of the two luminous dot arrays are arranged in an offset manner while being deviated from each other in the main scanning direction by a distance equal to the dimension thereof in the main scanning direction. Also, a reduction optical system is arranged for carrying out irradiation of light emitted from the luminous dots while reducing a dimension of the light in the sub-scanning direction by a reciprocal of the predetermined magnification.

A photographic recording apparatus capable of being small-sized and simplified in structure and reducing color aberration of an optical system. A refractive index distribution type lens array has a central axis arranged perpendicularly to a light emission direction of a fluorescent luminous tube. Light emitted from the fluorescent luminous tube passes through red (R), green (G) and blue (B) color filters, is incident on the lens array, is reflected on a first mirror and then is guided to a color film, resulting in forming an image on the color film. The fluorescent luminous tube is driven depending on data on R, G and B colors and the whole apparatus is moved with respect to the color film. The color filters are changed over and scan of the color film is carried out three times, so that an image of R, G and B colors may be formed on the color film.

An optical write element is adapted to be used in an image writing device to form a visual or latent image on a recording medium. The optical write element comprises a rectangular casing having an interior maintained in a high vacuum condition, at least one light-emitting dot array composed of multiple fluorescent light-emitting dots attached along the length of a substrate as part of the casing, at least one cathode placed above the light-emitting dot array, and a pair of shielding members placed over the outside of the light-emitting dot array.
摘要:
A fluorescent luminous device capable of permitting vibration of a filamentary cathode due to any external vibration or shock transmitted thereto to be readily attenuated, to thereby substantially prevent flickering of a display due to a variation in luminance of the luminous section, resulting in improving quality of the display. A part of a vibration adsorbing element provided at the end of a filamentary cathode is separatably contacted with the fixed portion of an envelope in which the element and cathode are arranged.

A fluorescent display tube, which has short-length filaments, can be driven by applied voltage of 3-8V to be used for a general fluorescent display tube. The fluorescent display tube can emit sufficient thermal electrons even if the number of filament cathodes is decreased to reduce power consumption of the filaments. The filament cathode is arranged between a first and third supporting plates by one end thereof fixed to the first supporting plate and the other end thereof fixed to the third supporting plate, and the filament cathode having an equal length with the filament cathode extended between the first and third supporting plates is arranged between the second and third supporting plates.
摘要:
There is provided an image processing apparatus which is capable of maintaining high data security and provide high convenience and high security. When a print request is transmitted from a client PC to a printer in a security print mode, a main CPU of the printer determines whether or not print data received from the client PC is for printing in the security print mode. If the print data received from the client PC is determined to be for printing in the security print mode, the main CPU causes all of the print data and temporary data to be erased from the hard disk.
