Abstract:
A recording medium dispensing device which may be used as a three-dimensional glyph producing stylus or a two-dimensional record producing stylus or pen (either nib type or stylographic type) having one or more pressurized recording medium containers and control means for individually controlling the dispensing of recording medium from the containers, and having separately controllable withdrawing means for withdrawing previously dispensed recording medium from the recording volume or surface.
Abstract:
A three-dimensional display device including a cathode ray tube having a plurality of spaced, parallel light and electron pervious display planes. Each of the display planes is divided into a plurality of display zones disposed in a two-dimensional array such that a line perpendicular to any display zone passes through a corresponding display zone in every display plane. Each of the display zones is provided with a single luminescent element of smaller area than that of the display zone. The luminescent elements on successive corresponding display zones are nonoverlapping so that substantially all of the luminescent elements are visible from one end of the plurality of display planes, and an electron beam from a gun disposed at one end of said plurality of display planes may readily impinge against selected ones of the luminescent elements in any one of said planes. The single display plane whose luminescent elements are to be excited at any given time is selected in accordance with a depth signal, and the elements to be excited are then selected by sweeping and modulating the beam.
