Title: Method of manufacturing panel for gas discharge
Inventor: SHINODA TSUTAE
IPC: H01J11/46
Filed: 1983-11-14
Abstract: PURPOSE:To obtain a panel for gas discharge having high quality without causing defective discharging points by sealing the circumferential portions of two substrates one substrate is opposed to and positioned on the other substrate holding spacers. CONSTITUTION:Linear electrodes 2 are formed at 0.5mm. pitch in such a way as to avoid small holes, H with 1cm pitch which are preformed on the surface of a glass substrate 1. And thereafter, a layer of dielectric and a protective layer 3 of MgO are formed by a thin film method or a thick film method in order. Small holes H0 corresponding to small holes H are formed on the surface of the laminated insulation layer 3. When a plurality of ball-like glass pieces 4 pass on the surface of the laminated insulation layer 3 in rolling motion, the glass pieces 4 are captured in a group of about 98% of small holes H0. An electrode substrate structure B is overlapped and positioned on the electrode substrate structure A. And thereafter, both electrode substrate structure A and B are heated in a heating furnace, and are integrated by melting the glass on the circumferential portion. A group of the ball-like glass pieces 4 is melted and secured by a laminated insulation layer 7 during the burning.

IPC: H03M1/10
Filed: 1985-09-30
Abstract: PURPOSE:To reproduce sharply picture information by selecting one of plural processing modes by plural binary-coding means in response to a difference signal. CONSTITUTION:A smoothing threshold signal S1 sent from a smoothing processing circuit 1 and a picture original signal S2 are subject to difference absolute calculation by a subtraction circuit 4, and when its quantity is larger than a parameter signal delta, the picture original signal S2 is binary-coded based on the smoothing threshold signal S1 in the vicinity. Conversely, when the quantity is smaller than the parameter signal delta, the smoothed threshold signal S1 is binary-coded based on a prescribed threshold value K. That is, the picture lowered by the MTF is binary-coded by using a mean value near the noted picture element as the threshold value, the dirt of background part and uneven density are binary-coded by using a preset fixed threshold value so as not to be binary-coded as picture information. Thus, excess noise component is suppressed and binary coding with fidelity is attained and a sharp picture is obtained.
