Abstract
Abstract A storage and display system for alphanumeric information or the like utilizing a storage tube, the target of which includes separate storage areas for character configuration and character digital data. Characters are written in common form in the first of said areas which is read and transferred to a visual display and in digital form in the second of said areas which is read and transferred to information storage or utilization means. There is a direct correlation between the information stored in the two areas.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
A storage and display system for alphanumeric information or the like comprising: a storage tube having an on-screen target area for storing character configuration data of alphanumeric characters in common form and an off-screen target area for storing character data of alphanumeric characters in digital form; means for writing said character configuration data in common form on the on-screen target area and for writing said character data in digital form on the off-screen target area in direct correlation with the character configuration in common form; character configuration data utilization means; character digital data utilization means; means for reading out stored information from the on-screen area or the off-screen area and transferring said read out signal respectively to the character configuration data utilization means or the character digital data utilization means, respectively.
Claim 2
Dependent Claim
131 words
A storage and display system for alphanumeric information or the like comprising: a storage tube having an on-screen target area for storing character configuration data of alphanumeric characters in common form and an off-screen target area for storing character data of alphanumeric characters in digital form; means for writing said character configuration data in common form on the on-screen target area and for writing said character data in digital form on the off-screen target area in direct correlation with the character configuration in common form; character configuration data utilization means; character digital data utilization means; means for reading out stored information from the on-screen area or the off-screen area and transferring said read out signal respectively to the character configuration data utilization means or the character digital data utilization means, respectively.
Claim 3
Dependent Claim
19 words
Apparatus in accordance with claim 1 wherein said digital data utilization means comprises a storage means for said data.
Claim 4
Dependent Claim
23 words
Apparatus in accordance with claim 1 wherein said configuration data utilization means include a CRT for displaying said characters represented by said data.
Claim 5
Dependent Claim
27 words
Apparatus in accordance with claim 1 wherein said on-screen area is rectangular in shape and the off-screen area is a perimetric segment contiguous with the on-screen area.
Claim 6
Dependent Claim
74 words
Apparatus in accordance with claim 4 wherein said writing means includes means for positioning the electron beam at a selected location for writing said character in common form in the on-screen target area and means for thereafter reducing by a fixed factor the positioning deflection voltages along the coordinate direction between the said storage areas, to thereby position the said beam for writing the same character in digital form in the off-screen target area.
Claim 7
Independent Claim
112 words
A method for using a storage tube in a display system including CRT display means and digital data utilization means, comprising: assigning separate on-screen and off-screen areas on the target of said storage tube for storage of character configuration in common form and character digital data in digital form; writing characters onto said tube target in common form at said on-screen area and in digitally encoded form at said off-screen area; reading out said on-screen area and utilizing said readout to modulate a scan raster at said CRT to visualize said characters; and reading out said digital data from said off-screen area and transferring said data to said digital data utilization means.
Claim 8
Independent Claim
112 words
A method for using a storage tube in a display system including CRT display means and digital data utilization means, comprising: assigning separate on-screen and off-screen areas on the target of said storage tube for storage of character configuration in common form and character digital data in digital form; writing characters onto said tube target in common form at said on-screen area and in digitally encoded form at said off-screen area; reading out said on-screen area and utilizing said readout to modulate a scan raster at said CRT to visualize said characters; and reading out said digital data from said off-screen area and transferring said data to said digital data utilization means.
Claim 9
Dependent Claim
21 words
A method in accordance with claim 6 wherein said characters are written in direct correlation on said on-screen and off-screen areas.
Claim 10
Dependent Claim
43 words
A method in accordance with claim 7 wherein said characters Are positioned for writing in said off-screen area by utilizing the pair of deflection voltages used to position said characters in said on-screen area, reduced in one deflection direction by a fixed factor.
