Definitions

  • the corpuscular beam which preferably is an electron beam
  • the corpuscular beam may be arranged to oxidise,- decompose, or vary chemically in some other manner, the surface of the support to be provided with picture or writing characters.
  • the individual layers may be arranged to be removed more or less by the energy of the impinging electrons or other corpuscles, so that, provided the structure or colour of the individual layers is different, black-and-white or multi-colour contrasts are produced after the lower layers have become exposed according to the intensity of the corpuscular beam.
  • the paper supports are preferably wound continuously during the writing from spools and are passed transversely through the beam at a suitably chosen velocity and re-wound on another spool, the relative movement in the other direction being effected by controlled deflection of the corpuscular beam. It is, however, also possible for the corpuscular beam to be deflected in an inertialess manner in two mutually perpendicular directions by means of known per se magnetic and electric devices, so
  • a predetermined section or strip on the support is provided with area-shaped picture contrasts.
  • the writing process generally cannot be effected in the generating chamber for the corpuscular beam, since this chamber is under high vacuum conditions and the de- 3 composition of the surface of the supports on which the pictures or writing characters are to be Produced will produce vapours and gases in rather considerable quantities, which would deteriorate the vacuum and would makenecessary continuous powerful pumping involving 1 loss of time in order that a high vacuum may be produced and maintained. More particularly paper will always yield in a high vacuum great quantities of gas. Moreover the introduction of the picture material through locks into the vacuum involves considerable technical difficulty.
  • the corpuscular beam in this case passes throuugh the fine bores 19, 20 and 21 aligned relative to it, which are provided in the partition walls 13, 14 and 15, thus avoiding the diffusion losses and detrimental heating of the parts of the apparatus which are inherent in the use of material windows.
  • the pressure in the individual chambers rises in a step-wise manner from the vacuum to the pressure, preferably equal to the outside pressure, which prevails in the writing chamber 7, where the support 18 that is to be provided with writing or the like is moved by means of take-up and supply rollers 8 and 9 transversely across the corpuscular beam, or where, in the case of controlled deflection of the corpuscular beam, the support to be provided with writing is scanned.
  • the individual chambers are connected with suitable pumps 10, 11 and 12 for maintaining the appropriate pressure conditions. For this reason the quantities of gases which flow through the fine nozzles from the chambers in which gas pressure is higher into the chambers in which gas pressure is lower will not lead to an undesired increase in pressure in the chambers at the vacuum side.
  • the method ac cording to the invention due to its simplicity and multilateral adaptability, has advantages which are of great importance in practical use.
  • I 1 I 1.
  • a syst'emfor the production of' a permanent record comprising a vacuum-tight casing defining achamber, means for maintaining fa high vacuum in said chamber, electrical and electro-magnetic means for generating, accelerating and focussing an electron beam in'said chamber, a casing defining a recordingchamber, said recording chamber being under substantially atmospheric pressure, a pressure-stage system defining pressure chamber means, said pressure-stage system being connected to and arranged between the high-vacuum chamber and the recording chamber, respectively, partition walls'between the high-vacuum chamber and the adjac'ent'presv contrasts generated in said surface, and the support lating the intensity. of said electron beam.
  • the support having an electron-sensitive surface capable of being modified to produce said permanent record by plate
