Abstract: PROBLEM TO BE SOLVED: To prevent a crack in a quartz material film and the peeling of the quartz material film even though the fully thick quartz material film is formed by relaxing a thermal stress, which is generated by a difference between the thermal expansion coefficients of both of a quartz material layer and a silicon carbide material layer, by a method wherein a composite layer consisting of both of the quartz material layer and the silicon carbide material layer is formed between the quartz material film and a silicon carbide material. SOLUTION: In the case where a quartz material film is formed on the surface of a silicon carbide material, a composite layer consisting of a quartz material layer and a silicon carbide material layer is formed between the quartz material film and the silicon carbide material. The composite layer is a mixed layer of a silicon carbide layer with a quartz layer and preferably, a silicon carbide sintered body is formed into islands structure, wherein quartz exists in this silicon carbide sintered body as a dispersion phase in a matrix (continuous phase).  By making such a composite dispersion phase interpose between the quartz material film and the silicon carbide material, the enhancement of the adhesion of the quartz material film and the silicon carbide material due to a relaxation of a thermal stress between the quartz material layer and the silicon carbide material layer, a shut-off of impurity diffusion due to the existence of the composite dispersion phase itself and moreover, the formation of a thicker quartz material film are made possible.

On one hand, reinforcing fibers 5 and 6 are set in a top force 3 and a bottom force 4, to both of which gelcoat is applied and hardened in advance. After that, the reinforcing fibers are coated and impregnated with liquid resin. Before the hardening of the liquid resin, the core material 1 is set in the bottom force 4 and the top force 3 is put upon the bottom force 4 in order to be clamped together. The liquid resin permeates in the gap made between both the forces 3 and 4 and the core material 1. At the same time, the reinforcing fibers 5 and 6 are butted against each other. Upon the joint of these fibers, the reinforcing fiber 2, which is mounted to the peripheral edge part of the core material 1 and fixed to it by resin, is placed. Under the above-mentioned condition, the resin is heated and hardened.

Inventor: TAKAHASHI SUSUMU
IPC: G02F1/1343
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To suppress the direction and range of reflected light and to emit reflected light which has no regularly reflected component and has many scattered and reflected components by adopting an interference pattern which is formed with scattered light of light having coherence, as an irregular pattern. SOLUTION: A transmission type diffusion plate 11 like frosted glass is lit with illumination light 15 having coherence like laser light. Diffusion light 16 diffused by the diffusion plate 11 reaches a photosensitive material 14 like a photoresist dry plate. The illumination light 15 has coherence, so a speckle pattern which is a diffraction pattern is formed on the photosensitive material 14 with the diffused light 16. This speckle pattern can be recorded by developing the photosensitive material 14. When the diffusion plate 11 is made larger vertically than horizontally, the speckle pattern becomes thinner vertically than horizontally. Thus, the diffusion plate 11 is properly sized to control the spatial frequency distribution of the pattern on the photosensitive material 14.

Title: Light amplifier
Inventor: KOGA MASABUMI
IPC: H01S3/067
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To control and keep constant average output levels regardless of any variation in the number of wavelength multiplexing or input levels by using as a control signal the difference between the average output level of each channel and a reference level. SOLUTION: For N channels where signal light is output, the output level of each port on an optical branching filter 16 is obtained by adding up the respective signal light intensity Ps and spontaneous emission light intensity PASE. For (M-N) channels where no signal light is output, the output level is spontaneous emission light intensity PASE The optical components of each channel are converted into electrical signals by an optical detector 14, which does not have to respond to the modulation speed of a main signal system and only requires as narrow frequency characteristics as direct current through tens of MHz.  Therefore, at the N channels where there is signal light, a direct- current voltage VH corresponding to the optical intensity (PS+PASE) is output, and at the (M-N) channels where there is not signal light, a direct-current voltage VL corresponding to the optical intensity PASE is output. This makes it possible to control the output level of each channel and keep them constant.
