Title: Production of composite material of organic polymer and metal oxide
Inventor: MURATA KAZUTAKA
IPC: C08J7/16
Filed: 1995-05-26
Abstract: PURPOSE: To produce a composite material of an organic polymer and a metal oxide which is useful as a variety of molding materials, electric and electronic parts, machine parts, sport goods, film, fiber and the 7 like because the organic polymer is improved in its thermal and mechanical characteristics such as stiffness by easily and arbitrarily micro-dispersing superfine particles of a metal oxide in a solid organic polymer that does not swell with the metal alkoxide. CONSTITUTION: An organic polymer of less than 1wt.% of swelling coefficient at equilibrium in tetraethoxysilane at 25 deg.C is swollen in a swelling solution such as an organic solvent or water, then the swollen organic polymer is impregnated with a solution containing a metal alkoxide. Then, the metal alkoxide is subjected to hydrolysis and condensation reaction to convert the alkoxide to the metal oxide whereby the objective composite material of an organic polymer and a metal oxide is obtained.

Title: Molten metal part cooler
Inventor: SHIMAZAKI HAJIME
IPC: B22C9/00
Filed: 1978-10-18
Abstract: PURPOSE:To increase the cooling speed of the head part of metallic patterns and shorten the casting cycle, by force-cooling the circumference of the head part of the metallic patterns. CONSTITUTION:After molten metal is poured into metallic patterns 1, 2, the molten metal gradually freezes. The pattern temperature sensor 12 provided near the prodcut part 4 detects freezing temperature and opens the electromagnetic valve 9 of the pipe 8 communicating to the upper part of the head part 6 from the pressure tank 11 of a cooling medium 10. As the cooling medium 10 is released, the head part 6 of the metallic patterns 1, 2 is force-cooled. To prevent overcooling, the freezing point of the head part 6 is detected with the pattern temperature detector 12 and the release of the cooling medium 10 is stopped by closing the electromagnetic valve 9. After this, the metallic patterns 1, 2 are opened and the product is taken out when the detector of either one reaches the preset temperature as detected by the pattern temperature detector 13 or by a timer.

The signal generator 204 generates and outputs a saw-tooth wave with a repetitive period T to the circuit 203. A beam splitter 205 as the optical multiplexing circuit multiplexes both the light beams again. The nonlinear optical crystal 206 outputs light with intensity proportional to the product of overlap intensity between the two input light beams of the output light of the optical multiplexing circuit. The photodetecting circuit 207 converts the output of the crystal 206 into an electric signal. The power spectrum measuring circuit 208 measures the power spectrum of a specific frequency component of the output of the circuit 207. The comparing circuit 209 compares the output of the circuit 208 with a set value previously and generates an output corresponding to the comparison result.

Title: Liquid crystal projector device
Inventor: NAKAMURA JUNPEI
IPC: G02F1/1335
Filed: 1990-05-18
Abstract: PURPOSE:To improve the contrast of a video displayed on a screen and its picture quality by providing an optical guide for passing only light beams included within a prescribed angle or its allowable angle out of light beams emitted from a back light. CONSTITUTION:Light projected from the back light 2 is reflected forward by a rear reflector 3 as beams including more parallel beams, the beams other than the prescribed allowable angle are absorbed by the optical guide 5 and only the parallel luminous fluxs reach the liquid crystal panel 4. An image displayed on the panel 4 is projected by the parallel luminous fluxs and projected on a screen 10 through a forward projection lens 9. Since only the parallel luminous fluxs are used for projecting the image displayed on the panel 4, the outline of the image can be clearly projected. Consequently, the contour of the image projected on the screen and the color reproducibility of the image can be improved and the picture quality of the video can also be improved. Thus, the high-definition image is obtd.

Title: Welding method of optical fiber and device therefor
Inventor: JIYANNPIEERU PANDEI
IPC: C03B37/14
Filed: 1980-09-16
Abstract: A process for fusion joining the ends of optical fibers includes aligning the ends of the two fiber cores to be joined facing each other such that at least one of the ends is free to be displaced laterally and there is no axial force between the two ends. The ends of the fibers are heated by producing a heat field with a predetermined distribution, for a predetermined period until attenuation of light transmitted through the fused joint increases, so as to cause partial fusion of the cores while maintaining sheathing of the fibers intact. A device for fusion splicing the two ends includes two opposed fiber supports for maintaining the end portions of the optical fibers to be fusion spliced in an approximately aligned position, the supports being slidable along the axes of the fibers being mounted on said supports such that their ends are free to move laterally. Optical means, such as a binocular microscope, is provided for checking whether the ends of the fibers are in the position where they engage one another without exerting any axial force on each other. A propane-oxygen flame heating device establishes a controlled distribution of heat field for heating the core ends.
