Abstract

785,578. Electric digital-data-storage apparatus. WESTERN ELECTRIC CO., Inc. Jan. 27, 1956 [Feb. 4, 1955], No. 2743/56. Class 106 (1). [Also in Group XL (a)] The dielectric target of a storage tube has the back plate and the barrier or field equalizing grid electrode connected respectively to inner and outer conductors which are electromagnetically coupled together as in a coiled coaxial line. In Fig. 1, the beam from a focusing and deflecting system 11-17 scans a dielectric sheet 23 which is enclosed with the back plate 22 in a shielding member 26 to which the barrier grid 24 is attached. The back plate is raised temporarily to a positive potential by a writing signal, the incident beam charging the elemental area negatively until it reaches equilibrium at the potential of the barrier grid. The writing circuit is applied to the inner and outer conductors 29, 30 of a coaxial line 28, the inner conductor 29 being connected to back plate 22 and the outer conductor 30 which is of thick brass to reduce resistance, is connected to the barrier grid 24. During writing, the flow of currents in the coiled portion 32 are in opposite directions and it behaves as a non- inductive winding. During reading, the negatively charged elemental areas are discharged by secondary emission greater than unity and current flows in both conductors in the same direction producing a signal voltage across the coiled portion and the load 34 for feeding to amplifier 35. The writing signal induces little or no signal in the reading amplifier. A magnetic or ferrite core may be included in the coiled conductors 32. A cancelling pulse generator operated by the writing source may feed to the amplifier 35 to correct the residual error due to the unbalance of current flow in the two conductors of the coaxial line. The storage target may be a back plate carrying small spots or islands of dielectric material and the coil portion of the coaxial line may be connected by a transformer coupling to the output amplifier (Fig. 4, not shown). Specification 701,010, [Group XL (a)], is referred to.
