Filed: 1989-08-28
Abstract: PURPOSE:To quicken the production of a high coding rate by deleting two-series of coding data series subject to convolution coding whose coding rate is 1/2 in accordance with a delete pattern decided in advance. CONSTITUTION:A transmission data series D and a transmission clock signal CL 1 are inputted to a convolution coding circuit 11, in which they are converted into coded data series P, Q.

Title: Fluorescent character display tube
Inventor: KAMIKUBO ISATO
IPC: H01J29/30
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To enable stereoscopic display by producing a luminance with the same positive electrode voltage applied, by coating one and the same segment with two kinds of fluorescent materials, i.e., a conventional ZnO:Zn fluorescent material and a fluorescent material of different luminous efficacy which is made by blending the above material with non-luminous matter. SOLUTION: A designated segment in one and the same fluorescent character display tube is coated with two kinds of fluorescent materials, i.e., a fluorescent material which is made by blending a ZnO:Zn fluorescent material with non- luminous matter, In2 O3 , at the rate of 25 to 40wt.% relative to ZnO:Zn and the conventional ZnO:Zn fluorescent material. After the tube is vacuum-locked, when the same positive electrode voltage is applied for light emission, a luminance ratio of the different fluorescent materials becomes smaller than 70% which can be detected by human eyes, and stereoscopic display is enabled by brigtness/darkness of the luminance ratio.
