Abstract: PROBLEM TO BE SOLVED: To provide a device having fiber plug gratings subjected to tamperature compensation. SOLUTION: This article has a supporting member 11 and an optical fiber 13 of a certain length which is mounted at this supporting member 11 and has a reflection wavelength λ at a certain temp. (for example, 20 deg.C). This supporting member 11 is a material having a negative coefft. of thermal expansion and contains a compsn. selected from a group consisting of a Zr-tungstate- base compsn. and an Hf-tungstate-base compsn. The material having a positive coefft. of thermal expansion is selected from a group consisting of Al2 O3 , SiO1 , ZrO2 , MgO, CaO and Y2 O3 .

Abstract: A silica sol-gel fabrication process is provided which allows improved control of the shrinkage that takes place during the drying of a gel body. In particular, the invention makes it possible to attain extremely low shrinkage through the completion of the drying stage, e.g., below 1% linear shrinkage, in relatively large sol-gel bodies of (dry weight) 1 kg or more, typically 10 kg or more, or even 40 kg or more, compared to the much higher shrinkages typically encountered. Specifically, use of a particular polymeric additive makes it possible for a gel body to experience linear shrinkage at least 55% less than an identical process without the polymeric additive.

Abstract: The invention is a sol-gel extrusion process which allows fabrication of both thick and thin wall tubes. For example, the process is capable of preparing silica overcladding tubes in a manner easier than sol-gel casting processes, and also capable of preparing relatively thin substrate tubes, which are difficult to cast. According to the invention, a silica dispersion containing a stabilizing agent is provided, a gelling agent is added to the dispersion to induce gellation, and the resultant gel is extruded into a silica body, in the substantial absence, i.e. less than 0.5%wt., of polymeric material from the gel. Substantially avoiding the inclusion of such polymeric material in overcladding and substrate tubes offers significant commercial advantages by reducing the time and energy required to remove organic materials from the tube bodies, by reducing environmental impact and by reducing the amount of impurities introduced in the tubes.

Abstract: The invention provides an improved process for fabricating devices containing metallized magnetic ceramic material, such as inductors, transformers, and magnetic substrates. The invention relates to use of an improved conductive material in such a process, the conductive material containing silver/palladium particles, ferrite particles, a cellulose-based or other organic binder, and a solvent. After firing of the substrate onto which the ink has been coated, and plating of copper thereon by a copper pyrophosphate bath, the plated copper exhibits a pull strength greater than about 4 kpsi, advantageously greater than about 5 kpsi. Use of a copper pyrophosphate bath also allow uniform plating within long, narrow vias.
