 G03

Note(s)

In this class, the following terms are used with the meaning indicated:

  • "records" means photographs or any other kind of latent, directly-visible or permanent storage of pictorial information, which consist of an imagewise distribution of a quantity, e.g. an electric charge pattern, recorded on a carrier member;
  • "optical" applies not only to visible light but also to ultra-violet or infra-red radiations.

 G03B
APPARATUS OR ARRANGEMENTS FOR TAKING PHOTOGRAPHS OR FOR PROJECTING OR VIEWING THEM; APPARATUS OR ARRANGEMENTS EMPLOYING ANALOGOUS TECHNIQUES USING WAVES OTHER THAN OPTICAL WAVES; ACCESSORIES THEREFOR (optical parts of such apparatus G02B; preparing or processing photosensitive material G03C, G03D)
 G03B

Note(s)

This subclass covers, as far as processes are concerned, only processes characterised by the use or manipulation of apparatus classifiable per se in this subclass.


 G03C
PHOTOSENSITIVE COMPOSITIONS OR BASES CARRYING THEM; PHOTOGRAPHIC PROCESSES, e.g. CINE, X-RAY, COLOUR, STEREO-PHOTOGRAPHIC PROCESSES; AUXILIARY PROCESSES IN PHOTOGRAPHY (photographic processes characterised by the use or manipulation of apparatus classifiable per se in subclass G03B, see G03B; electrography, electrophotography, magnetography G03G)

 G03D
APPARATUS FOR PROCESSING EXPOSED PHOTOGRAPHIC MATERIALS; ACCESSORIES THEREFOR (chemical processes for photographic materials G03C; electrographic, electrophotographic, or magnetographic methods or apparatus G03G)

 G03F
PHOTOMECHANICAL PRODUCTION OF TEXTURED OR PATTERNED SURFACES, e.g. FOR PRINTING, FOR PROCESSING OF SEMICONDUCTOR DEVICES; ORIGINALS THEREFOR (phototypographic composing devices B41B; photosensitive compositions, photographic processes G03C; electrography, sensitive layers or processes therefor G03G)

 G03G
ELECTROGRAPHY; ELECTROPHOTOGRAPHY; MAGNETOGRAPHY (information storage based on relative movement between record carrier and transducer G11B; static stores with means for writing-in or reading-out information G11C; recording of television signals H04N 5/76)
 G03G

Note(s)

  1. This subclass covers the production of permanent directly-visible pictures in conformity with an original picture or document, using an imagewise distribution of an electric or magnetic quantity, such as a charge pattern, an electric conductivity pattern, or a magnetic pattern.
  2. This subclass does not cover:
    • use of electric signals for the transmission of the picture information from the original to the reproduction, i.e. pictorial communication, which is covered by subclass H04N;
    • production of pictures by heat patterns exclusively, not using an electrostatic or magnetic pattern, which is covered by group B41M 5/00;
    • production of prints by transferring ink from a printing form to a printing surface, without physical contact and using the force of an electrostatic field, which is covered by subclass B41M.

 G03H
HOLOGRAPHIC PROCESSES OR APPARATUS (holograms, e.g. point holograms, used as ordinary optical elements G02B 5/32; producing stereoscopic or other three-dimensional effects G02B 27/22; diffraction-grating systems G02B 27/44; systems using moire fringes G02B 27/60; optical logic elements G02F 3/00; stereo-photography G03B 35/00, G03C 9/00; analogue computers performing mathematical operations with the aid of optical elements G06G 9/00; holographic digital storage G11C 17/00)  [2]
 G03H

Note(s)

This subclass covers means for producing a record of the phase and amplitude information of a wave-front, which information can be used to reconstruct the original wave-front, or means to reconstruct the original wave-front from a record containing the phase and amplitude information of the wave-front. [2]
