Title: Method of forming solid electrolytic layer in capacitor element for solid electrolytic capacitor
Inventor: NAKAMURA TAKAHIRO
IPC: H01G9/032
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility that a specific chip piece from among chip pieces becomes defective, because it is out of a specified size/shape due to an excessive liquid for solid electrolytic layer sticking to it when impregnation in the liquid for a solid electrolytic layer, swishing off of the liquid, and baking thereafter are repeated with each of a plurality of chip pieces fitted to a lateral bar for forming a solid electrolytic layer. SOLUTION: When a chip piece 2 at a lateral bar 10 is swished off so as to part from the liquid for a solid electrolytic layer, the lateral bar 10 is so tilted as its one end part is lowered by an appropriate angle, thus much liquid for solid electrolytic layer sticks to at least one chip piece 2 from among chip pieces 2 at the lateral bar 10, which is positioned at one end part of lateral bar 10, while excess liquid for a solid electrolytic layer sticking much to the one chip piece 2 is absorbed with a swishing member contacting or cross to the one chip piece 2.

Title: Production of liquid crystal display device
Inventor: WATANABE NORIKO
IPC: G02F1/1337
Filed: 1993-08-31
Abstract: PURPOSE:To easily control the visual angle direction by a pretilt angle. CONSTITUTION:The pretilt angle is stably controlled by controlling the quantity of oxygen affecting the surface of an oriented film 31c covered with a light shielding part 11a. The following two methods are applicable to the control of the oxygen quantity. One thereof is a method of subjecting the oriented film 31c to photoirradiation in an atmosphere partly replaced with an inert gas. The photoirradiation may be executed in a 100% inert gas. The ratio of the inert gas in the ordinary atm. is 80%. A reaction speed does not lower so much with the photoirradiation in the atmosphere contg. 85% inert gas but there is some influence on the light shielding part 11a. The light shielding part is not affected at all by the photoirradiation in the 100% inert gas but the reaction speed is lower. Another one is a method for subjecting the oriented film 31c to photoirradiation under a reduced pressure. This photoirradiation may be executed in the perfect vacuum. The reaction speed is lower as the degree of the reduced pressure is higher in this case, too.
