IPC: G09F9/35
Filed: 1992-04-21
Abstract: PURPOSE:To precisely and constantly control a liquid crystal cell gap over the entire screen by combining printing, polishing, and sand blast machining. CONSTITUTION:Space 10 for discharging are left between adjacent laminate structures of partition walls 11 and plasma electrodes 12 formed in stripes. Thus, a conductor layer and a dielectric layer are etched with a sand blast at the same time to obtain the laminate structures of the partition walls and plasma electrodes 12 which completely match each other. Therefore, the problem of an alignment error generated when the electrodes 12 and partition walls 11 are formed one over another by direct screen printing is eliminated and surface states which are polished and flattened in advance are left on the top surfaces of the partition walls 11 as they are. Thin plate glass is supported by the partition walls 11 which has the smooth top surfaces and are at constant height, and then their flatness is maintained to control the liquid crystal cell gap uniformly over the entire image surface.

IPC: C02F9/00
Filed: 1990-05-18
Abstract: PURPOSE:To perfectly remove an endotoxin especially difficult to remove among pyrogens by transmitting pyrogen-containing water through an adsorbent layer and a precise filter membrane module and subsequently transmitting the same through an ultrafiltration membrane module. CONSTITUTION:Tap water is transmitted through a packed bed of an adsorbent represented by activated carbon to adsorb and remove residual chlorine or org. matter (offensive smell components such as a mold smell or pyrogens). Further, the fine particles such as iron rust or bacteria in tap water are prevented from transmission by a precise filter membrane module. An ultrafiltration membrane module perfectly blocks pyrogens not remove by the adsorbent and the precise filter membrane module. Therefore, as the ultrafiltration membrane module, one showing fractionating characteristics (a nominal fractionation mol.wt.(MW) being an MW showing an inhibition ratio of 90% on the basis of polyethylene glycol is about 10000) or one required in characteristics on a further small MW side is used.

Title: Formation of via of multilayer ceramic board
Inventor: INOUE SADAO
IPC: H05K3/46
Filed: 1990-05-18
Abstract: PURPOSE:To enable formation of a via having high reliability by filling a via hole with metallic powder as a conductor and by closing it up by metallic paste thereafter. CONSTITUTION:As a conductor 4 to fill a via hole 3, an organic binder is not used but a copper powder 4a alone is used.
