| Number | Title | Issue Date |
| 8058789 | Cathodoluminescent phosphor lamp having extraction and diffusing grids and base for attachment to standard lighting fixtures A light emitting device has a cathode-ray tube and power supply. The cathode-ray tube in an embodiment is optimized for emitting a broad electron beam, in one variation a dome-shaped diffusing grid is used to spread the beam. In another embodiment, the device has a ... | 11/15/2011 |
| 6369498 | Electron gun for addressing secondary emission targets A dual-gun, single neck CRT focuses two beams, with significantly differing energies, onto a secondary emission target while maintaining compatibility with a standard fourteen-rotation stem and achieving FTU in excess of 95%. A pair of Einzel guns (write ... | 04/09/2002 |
| 4352043 | Cathodoluminescent light sources and electric lighting arrangements including such sources A cathodoluminescent lamp for use for general lighting service includes an anode constituted by an electrically conducting coating, which may be partly internally reflective, on the interior surface of the bulb wall, a phosphor coating over the whole of t... | 09/28/1982 |
| 4275355 | Direct view storage tube having improved readout performance A flood gun assembly for use in a cathode ray storage tube for uniformly distributing flood electrons over the surface of a storage target includes a mounting member for mounting the flood assembly within the storage tube and on which first flood gun mean... | 06/23/1981 |
| 4193014 | Display arrangements An addressable display in which data is presented in the form of a rectangular dot array is provided by means of an evacuated cathode ray tube, which enables large bright displays to be achieved. The cathode ray tube contains two segmented mesh electrodes... | 03/11/1980 |
| 4185226 | Spray gun for a direct-vision image storage tube and an image-storage tube using this gun A quadripolar lens incorporated in the spray gun of direct vision image storage tubes enables the density of electrons in the spray beam to be controlled, over a wide range, by acting on the potential of the control grid of the gun, without varying the ac... | 01/22/1980 |
| 3970889 | Erasure means for charge storage device In a charge storage device, such as a high resolution scan converter tube, flood guns are incorporated to scan the target with substantially unfocused high current electron beams to provide the erasure thereof.... | 07/20/1976 |
| 3956712 | Area electron gun A plurality of thermionic filaments are arranged in side-by-side relationship. A spreader electrode which may be in the form of a flat plate is placed on one side of the filaments, while an anode is placed on the other side of the filaments, with a grid b... | 05/11/1976 |
| 3939378 | Storage cathode ray tube having auxiliary coils to correct non-symmetrical geometry A storage cathode-ray-tube having a single off-axis flood gun is described including auxiliary coils defining electromagnets placed, one electromagnet on either side of the cathode-ray-tube to correct non-symmetrical geometry in optical representations pr... | 02/17/1976 |
