IPC: H01J17/49
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To provide an image display device with high reliability without the occurrence of unnecessary discharge and damage of panel and drive element, by constituting a discharge drive stage of a discharge channel with a complementary circuit and inserting a resistor into the high voltage source side of this discharge drive stage. SOLUTION: The drive stage of a cathode electrode 19 is constituted of switching element group 22a-22c and the switching element groups 24a-24c, and a plasma discharging high voltage source 21 is connected to this stage. Then, the resistors 25 are inserted serially to respective switching elements 24a-24c. The resistance values of these resistors 25 are made the maximum resistance values that a plasma address liquid crystal display panel is operated normally since the potential of the cathode electrode 19 becomes undecided when the switching elements 22a-22c are turned off. In such a manner, by providing the resistors 25 on the high voltage source input side of the discharge drive stage, the damages of the display panel and drive element due to unwanted abnormal discharge, and a current flowing by it are prevented.

Filed: 1991-12-13
Abstract: PURPOSE:To prevent the generation of peeling-off by preventing the deterioration of adhering force of an earth pattern layer and an insulating adhesive layer. CONSTITUTION:By etching the first metallic foil of a laminated plate 3 formed by laminating a first and a second metallic foils 1, 2, an earth pattern layer 4 is formed. By superposing a third metallic foil 6 through a prepreg 5 on the earth pattern layer 4 and laminating and forming them, a multilayer laminated plate 7 formed by laminating a third metallic foil 6 by an insulating adhesive layer 12 is formed. By piercing, a via hole 8 extending from a second metallic foil 2 to an earth pattern layer 4 is provided and thereafter, by plating, a plating layer 9 is provided on the inner periphery of the via hole 8. By etching a second and a third metallic foils 2, 6, a circuit pattern layer 10 and a patch antenna element layer 11 are formed. Since a third metallic foil 6 is laminated on the earth pattern layer 4 in a process before executing plating to the via hole 8, it does not occur that a plating liquid works on a first metallic foil for forming the earth pattern layer 4.

Abstract: PURPOSE:To obtain a blood vessel substitute material excellent in bio- compatibility, by bonding a cell adhesive substance to the inner surface of an artificial blood vessel using extremely fine fibers at least in a part of the inner surface thereof and further bonding a vascular endothelial cell thereto in vitro. CONSTITUTION:In an artificial blood vessel used in a blood substitute material, extremely fine fibers of 0.5 denier or less are used at least in a part of the inner surface of said blood vessel and a cell adhesive substance such as collagen, gelatin or fibrin is applied to said inner surface.
