Inventor: KOSAKA MASAHIRO
IPC: B01D1/24
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a means which enables uniformly drying of a solid based slurry. SOLUTION: A clearance 9 is made at an upper part of a heating drum 2 to provide a non-heating top roller 3. The top roller 3 has a width W smaller than the width W of the heating drum, has a small-diameter part 3c, a tapered part 3d and a shaft part 3e at both ends thereof and is supported by a bearing 7 that allows adjusting of the axis position thereof.

Title: Phosphor paste for plasma display, production of plasma display panel, and plasma display panel
Inventor: NAKAMURA RYUICHI
IPC: H01J11/42
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To facilitate the confirmation of defects such as unevenness in applying phosphor by incorporating a dye free of any metallic component and capable of being burnt off. SOLUTION: A dye or pigment being free of any metallic component and capable being burnt off and desirably having the same color as the phosphor is incorporated in a phosphor paste used for a plasma display and obtained by adding ethylcellulose and butylcarbitol acetate to a red, green, or blue phosphor and pasting the mixture by milling with a roll mill. This facilitates the check of unevenness or the like in forming a phosphor surface on the substrate in the formation of a plasma display having white ribs. The reason why the colorant component being a dye or a pigment is selected so as to be burnt off is that substances being other than the phosphor and remaining after burning adversely affect the discharge for the image display of a panel, and the reason why it is selected so as to be metal-free is that the metallic component influences the emission wavelength of the phosphor.

Abstract: PURPOSE:To prevent the dielectric breakdown due to a static electricity by forming the yoke part of a second magnetic film so that the outer circumferential edge can be positioned inside of the outer circumferential edge of the yoke part of a first magnetic film. CONSTITUTION:The whole shape of a yoke part 42 of a second magnetic film 4 is smaller than a yoke part 22 of a first magnetic film 2 only by DELTAW approximately over the whole circumference and the outer circumferential edge is formed so as to be positioned inside of the outer circumferential edge of the yoke part 22 of a first magnetic film 2 only by DELTAW.

Filed: 1992-10-16
Abstract: PURPOSE:To make a combined display which uses plural frame buffers by constituting a frame buffer which outputs both a Z value showing depth information and an I value showing image information at the same time. CONSTITUTION:A Z value and an I value regarding one pixel are handled as one piece of information, so when they are sent out to a Z merging part, both the values are transferred preferably at the same time. For the purpose, a Z buffer is composed of a video RAM similarly to an image buffer 12 and has a RAM port for inputting and outputting the Z value to and from a drawing/control part 10 and a SAM port for outputting the Z value to the Z merging part. For a frame buffer which is so constituted as to store both the Z value and I value in one video RAM chip, the Z value and I value are outputted alternately from the SAM port. Further, those outputs are received alternately by flip-flops of two systems and then the Z value and I value can be transferred separately to the Z merging part.
