Abstract: PURPOSE:To enhance smoothness of a product surface by a method wherein a foamable heat insulation material is filled in a recessed portion of a synthetic resin base plate having the recessed portion formed to a longitudinal direction thereof and, thereafter, a molding roll having ribs is pressed down to reduce a foaming pressure against the base plate. CONSTITUTION:The base plate 2 having the recessed portions 1 formed into a U- shaped cross area channel over a total length thereof to a longitudinal direction is conveyed by a conveyor 8 as well as a synthetic resin foamable heat insulation material such as an urethane foamable material or the like is injected into aforementioned recessed portions 1 from an injection portion 9 and filled therein. Subsequently, to a direction across the aforementioned conveying direction at right angles, the molding roll 5 having the ribs 4 is pressed down an upper surface of the conveyed synthetic resin foamable heat insulation material to foam and mold said material. Thereby, a high density skin layer can be molded on a surface of the synthetic resin foamed material as well as rib portions can be molded thereto and the strength of a product can be increased without increasing a thickness thereof.

Title: Method for joining ceramics
Inventor: NISHIKAWA TETSUYA
IPC: B23K1/19
Filed: 1991-06-27
Abstract: PURPOSE:To easily metallize a ceramic surface without using glass powders by applying Mo or W powders on the ceramic surface, further applying the powders to be added and coated with Ni and metallizing by heating. CONSTITUTION:A first metallizing composition consisting essentially of Mo powder or W powder is applied on the ceramic surface. Next, a second metallizing composition added with 2-20wt.% of Ni powder is applied and, in a reducing atmosphere, it is heated to 1300-1375 deg.C and after the ceramic surface is metallized, the ceramics and another ceramics or a metal are joined through a brazing operation. The first metallized layer causes a strong binding with the ceramics by the prescribed joining method and the second metallized layer binds good with the first metallized layer and also a wetting property due to the brazing agent is improved. According to the joining method, since glass is not included in the metallized composition, the quality control and the manufacturing process accompanied with joining are simplified.

When the plane of polarization of the optical fiber 6b for preserving the plane of polarization is rotated by the physical variation, the interference fringes at the input terminal surface of the optical fiber is expanded or contacted, and the parts of L2 and L4 become bright. Thus the physical variation at the measuring point can be detected highly accurately.
