Title: Method and apparatus for applying resist
Inventor: ENDO MASATAKA
IPC: B05D1/40
Filed: 1986-12-16
Abstract: PURPOSE:To make it possible to apply resist uniformly, by arranging a plurality of nozzles on a wafer in a scattered pattern, and dropping the resist on the wafer in resist application. CONSTITUTION:Nozzles 2 are provided vertically on the central part and on the four points of the peripheral part of a wafer 1. Photoresist is simultaneously dropped on the wafer, which is sucked with vacuum. The ratio between the thickness L1 of the resist at the central part and the thickness L2 at the peripheral part thereof is L1:L2=1:0.9, which is approximately uniform. Then the wafer is rotated up to 5,000 rpm for 10 seconds. The wafer is rotated intactly for 20 seconds. Thereafter the number of rotation is decreased to zero for five seconds. Then the difference in thicknesses of the resist 5a between the central part and the peripheral part is 10Angstrom  or less. The ratio between the resist thickness L1' at the central part and the resist thickness L2' at the peripheral part is L1':L2'=1.0:0.98. Thus the uniform application of the resist can be implemented for especially large-diameter wafers (6 inch or more). As a result, the yield rate of the elements is improved.

Title: Corrosion preventive treatment of vacuum brazed articles
Inventor: KUME YOSHIO
IPC: C23C22/66
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To effectively enhance the corrosion resistance of vacuum brazed parts for which Al alloy materials contg. Si are used by subjecting the surfaces of these vacuum brazed parts to a boehmite treatment without subjecting the surfaces to a pretreatment accompanied with an erosion effect. SOLUTION: The surfaces of the vacuum brazed parts formed by using the Al alloy material consisting of an Al-Si based alloy as a brazing filler metal are subjected to the boehmite treatment by using weakly alkaline water after washing with a detergent, etc., at need without subjecting the surfaces to the pretreatment, such as etching, accompanied with the erosion. As a result, oxidized films are uniformly formed with a good adhesion property via films, such as remaining extremely thin Al layers, etc., on the surface of the Al alloy contg. the exposed Si particles, by which the corrosion preventive treatment is effectively executed. The corrosion preventive surface is thereafter subjected preferably a sealing treatment by executing a pressure vapor treatment of about 3 to 5kg/cm<2> .  Even if the Si is crystallized near the article surfaces after vacuum brazing, the layers of the Al and oxidized films remain on their extreme surfaces and, therefore, the chemical conversion films free from the defects inclusive of the Si crystallized parts are obtd. by such treatment.

Title: Optical communication system
Inventor: KEBIN KURISUTOFUAA BAIRON
IPC: H04B10/54
Filed: 1990-11-05
Abstract: PURPOSE: To remove the solution type interaction by using a passive optical tube as an optical fiber so that a signal may be transmitted along it. CONSTITUTION: The optical fiber is a passive optical tube so that a signal may be transmitted along it. The solution effect requires a ratio dI/dt of the intensity change which provides self-phase modulation brought about in soliton. The intensity is fixed to remove dI/dt; ana as for the fiber, the dynamic Kerr effect doesn't exist so that certain light can be seen, and therefore, soliton type induction and repulsion are not caused. Thus, the soliton interaction in a conventional optical fiber system is removed, and the system can be used at a high bit speed with long fiber length.
