Title: Manufacture on thin film capacitor integrated circuit
Inventor: HAYASHIDA SUMIO
IPC: H01G4/08
Filed: 1981-02-06
Abstract: PURPOSE:To eliminate defective region of an electrolytically formed film and reduce shortcircuited faults by a method wherein polyimide resin is applied over a region except the surface of a dielectric film to be a capacitor, and a desired capacitor electrode is formed through resin being removed after heat-treatment for stabilization. CONSTITUTION:A tantalum nitride thin film 2 is formed on a ceramic substrate 1, and it is formed to be a desired pattern by photo etching a region of the film 2 is changed into a Ta pentoxide film 3 by anodic formation. Subsequently polyimide resin 5 is applied by rotating it, and resin 5 on the film 3 is removed by photo etching, and heat-treatment for stabilization is performed to the thus- prepared object for example in the air of 300 deg.C during 5hr. Subsequently the resin film 5 is removed and a thin film capacitor is fabricated by a metal electrode film 4 being attached and formed. By this method because of possible oxidation of thin regions or defective regions in electrolytically formed film, yield can be improved through reinforcement of the dielectric film.

IPC: G02B6/28
Filed: 1992-02-03
Abstract: PURPOSE:To enable the addition of light powers by having an optical coupling part where two optical waveguides are in approximate to each other and which is bent in the same direction, thereby varying the optical coupling ratio according to optical coupling directions. CONSTITUTION:The optical waveguide 11 and the optical waveguide 12 are formed nearly in parallel in proximity to each other. The curved part curved in the same direction by equaling the respective centers of curvature in such a manner that the radii of curvature attain R1, R2, is provided. The bent part of this distance L is formed as the optical coupling part 13. The optical waveguides 11, 12 are in proximity to each other in the optical coupling part 13 and, therefore, mode coupling of light arises and since the coupling part is curved, the propagated light bleeds to the outside of the respective optical waveguides 11, 12. Then, a difference arises between the optical coupling ratio from the outer optical waveguide 12 to the inner optical waveguide 11 and the optical coupling ratio from the inner optical waveguide 11 to the outer optical waveguide 12 and the optical coupling from the inner optical waveguide 11 to the outer optical waveguide 12 increases relatively. This optical coupling state is controlled by the degree of curving of the optical coupling part 13, the spacing W between the optical waveguides 11 and 12, etc.

CONSTITUTION:The finger 3 consists of a partly cylindrical head part 4, a base part 5 having a rectangular cross section and a leg part 6, in which the width of the head part 4 and the over-all height are proportionally increased from the front to the rear end. The drum body 1 is provided with grooves 7 having a cross-shaped cross section cut at regular intervals, and the fingers 3 are fitted into enlarged parts 8 of the grooves 7 so as to be movable in the radial directions. When the drum is stopped, the fingers 3 at upper parts of the drum are retracted under their own weights to the position where the bottom surface of the base part 5 contacts with a stepped part 12, and the surfaces of the head parts constitute a conical surface because the bottom surfaces are inclined. During the winding of the strand with the bobbin fitted on the drum, the fingers 3 are projected by the centrifugal forces and the upper surfaces of the base parts 5 are brought into contact with plate parts 13, so that the surfaces of the head parts 4 constitute a cylindrical surface to support the bobbin 14 uniformly. When the drum is stopped, the fingers 3 are retracted under their own weights, so that the bobbin can be drawn out easily even if it is deformed.
