Title: Electron gun for cathode-ray tube
Inventor: WASHINO SHIYOUICHI
IPC: H01J29/50
Filed: 1978-06-14
Abstract: PURPOSE: To reduce the aberration of the electron lens and thus to avoid the resolution impairment of the white characters and others by providing the electron lens which decreases the dispersion angle of the electron beam and also minimizes the increment of the normalized emittance of the electron beam.  
     CONSTITUTION: Radiation part E of the electron beam is formed with cathode 1 and the first half of 2nd grid 23; auxiliary electron lens A is formed with the latter half of grid 23 and the first half of 3rd grid 24; and main condenser electron lens B is constituted with the part from the latter half of grid 24 through 5th grid 27. Lens A decreases the dispersion angle of the electron beam radiated from part E and also minimizes the increment of the normalized emittance of the electron beam. Here, the potential of grid 23 is set higher than that of grid 24, and at the same time the length of grid 23 is set to prescrived multiplication as large as the inner diameter of the larger one of grid 23. As a result, the effect of aberration can be minimized to avoid the impairment of the resolution for the white characters and others.

Abstract: PURPOSE:To easily maintain and manage the titled device with a simple constitution, by forming an electrostatic latent image on the surface of a dielectric drum by giving optical signals responding to picture signals to an optical switch array installed near the dielectric drum by means of an optical switch driving means. CONSTITUTION:A bias voltage VB is applied across the space between the transparent conductive film 21 of an optical switch array 2 installed near a dielectric drum 1 and a conductive basic body 10. An optical signal from an LED at a specified location of an LED array 4 is irradiated upon a corresponding location in the direction of length of a photoconductive layer 22 of the optical switch array 2 through an SELFOC lens 3. Then the resistance at the location, upon which the optical signal is irradited, is reduced and becomes equivalent to the resistance when the optical switch is driven, and a discharge is produced between the location and the dielectric drum 1. By the discharge, an electrostatic latent image is formed and the image is developed and transferred. Since the electrostatic latent image can be formed by utilizing the optical signal in this way, the constitution can be made simpler and the device can be maintained and managed easily.
