Title: Production of optical fiber matrix
Inventor: ISHIGURO YOICHI
IPC: G02B6/00
Filed: 1988-09-21
Abstract: PURPOSE:To obtain the title matrix free from variation in dopant concentration by controlled heating of carbon in combination with a rare earth compound using an inert gas as a carrier gas while measuring the luminance temperature of said carbon. CONSTITUTION:A mixture of a rare earth compound 12 and carbon 13 is set up within a dopant chamber 11 provided so as to communicate to one end of a quartz tube 10. Thence, using an inert gas IG as a carrier gas, the chamber 11 is heated with e.g., an oxyhydrogen burner 14 to evaporate the rare earth compound 12 while controlling the luminance temperature of the carbon 13 to 800-1000 deg.C through a radiation thermometer without graphic display. The rare earth compound 12 evaporated is then deposited on the inner surface of the downstream quartz tube 10. Because the above processes are made in the inert gas IG when heating the rare earth compound 12, the oxidation of said compound can be prevented during heating. Furthermore, because the luminance temperature of the carbon 13 virtually 1 in emissivity is measured with a radiation thermometer, the temperature within the chamber 11 can be retained at the specified level and the amount of the compound 12 to be evaporated can also be controlled to a specified level, thus obtaining the objective high-quality optical fiber matrix.

Title: Semiconductor integrated circuit device
Inventor: SUZUKI KOICHI
IPC: H01L27/04
Filed: 1989-09-12
Abstract: PURPOSE:To enhance an electrical insulating property between a semiconductor substrate and an element region by a method wherein an insulating film arranged on a semiconductor board of low resistivity, a semiconductor active layer of high resistivity arranged on the insulating film, and a high conductive member so formed as to reach the semiconductor substrate penetrating through the surface of the semiconductor active layer and to electrically connect them together are provided. CONSTITUTION:Semiconductor active layers of high resistivity which form semiconductor elements are isolated from each other by a semiconductor substrate 1 and an insulating layer 2, so that the semiconductor active layers are excellent in electrical insulation property between them and small in parasitic capacitance between them. When the same breakdown strength is realized between the active layers, the insulating layer 2 can be made small in thickness, so that a high conductive member 4 can be made small in length. Therefore, the high conductive member 4 can be made small in resistance without increasing it in area. As the high conductive member 4 can be made small in area, a semiconductor chip can be made large in scale of integration as a whole. The semiconductor active layer 3 and the semiconductor substrate 1 can be fully insulated from each other through the insulating layer 2, so that an integrated circuit device of this design can be protected against latch-up and lessened in parasitic capacitance.

IPC: F02B75/18
Filed: 1984-11-09
Abstract: PURPOSE:To decrease the permanent deformation of a sleeve inner diam. during running, and to restrict the gap between a piston and the sleeve in order to prevent the short-circuiting of gas and the waste of oil by using a cast-iron sleeve of large wall-thickness in a specifically-casting and heat-treating casting stage and boring the inner diam. of sleeve. CONSTITUTION:Each large wall-thickness, high rigidity sleeve 3 having the wall thickness set to >=10% of its inner diam. is provided to a metal mold. Next, a stock Sm of cylinder block is cast by filling the metal mold with a molten aluminum alloy under pressure. The influence of the casting strain of cylinder barrel 1 on each sleeve 3 is small because of the large wall-thickness and high rigidity of each sleeve 3. Next, the casing strain of cylinder barrel 1 is decreased when the stock Sm is heat-treated. When the sleeve 3 is provided with boring work thereafter; the influence of the casting strain of cylinder barrel 1 on the sleeve 3 is almost eliminated even when the sleeve 3 is made to have the small wall-thickness and the low rigidity, because the casting strain of barrel 1 is decreased. In case of assembling and driving an engine by using the cylinder block obtained in such a way, the amount of permanent deformation of the inner diam. of each sleeve 3 is small.
