Title: Production of optical waveguide element
Inventor: KONDO MITSUKAZU
IPC: G02B6/13
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To substantially obviate the occurrence of difficulty in workability in putting into packages even in the case a substrate is obliquely connected by producing optical waveguide elements by cutting the substrate in such a manner that optical waveguide ends have an finite angle from perpendicularity to their end face and that the direction of the phase shift optical waveguides is not aligned to the ridge line direction of the flanks of the substrate. SOLUTION: The substrate is cut in such a manner that the optical axis at the ends of the optical waveguides 14 and the normal of the cut surfaces (element coupling end faces 4) attain an angle of α=5.4 to obtain the plural optical waveguide elements 1 of a parallelogram. On the other hand, the fiber coupling end face 23 of the optical fiber 20 to be optically coupled to the element coupling end face 4 of each of these optical waveguides 14 is formed by polishing in such a manner that the normal thereof attains the angle of β=8.0 deg.. A UV curing type adhesive is used for optical coupling of the element coupling end face 4 and the fiber coupling end face 23. The state that the entire part is crooked by the flexing as a result of connection of the optical fiber 20 and the optical waveguide element 1 is drastically reduced is such a manner.

Title: Method for molding ceramic part
Inventor: KUMAKI JUNICHI
IPC: C04B35/632
Filed: 1993-06-29
Abstract: PURPOSE:To provide the subject method designed to further surely prevent the ceramic part from cracking due to its drying by obviating the drying degree difference between the surface layer and the inside of a molded form of the ceramic part as far as possible. CONSTITUTION:In this method for making a molded form by injecting a slurry comprising ceramic powder, a solvent and a solidifying agent, into a mold a high-boiling solvent-contg. slurry is used when the surface layer 1 of the molded form is to be made, while a low-boiling solvent-contg. slurry is used when the inside 2 of the molded form is to be made. By this scheme, as the diffusion rate of the low-boiling solvent is higher than that of the high-boiling solvent in evaporating the solvent in the molded form, the movement of the solvent in the inside 2 to the surface is rapid, resulting in smaller volume shrinkage difference between the surface layer 1 and the inside 2 due to drying and drying rate. Therefore, the stress development in the molded form is suppressed and the cracking thereof due to drying can be prevented effectively.
