Title: Production of high-purity quatrz glass
Inventor: SHIODA EIJI
IPC: C03B20/00
Filed: 1988-12-09
Abstract: PURPOSE:To increase the transmissivity of the subject glass and to eliminate the 2,730nm absorption based on the OH stretching vibration by allowing the porous base material obtained by depositing fine SiO2 particles to react with a chlorinating agent, then removing the residual chlorinating agent and vitrifying the material. CONSTITUTION:Silicon halide (e.g. SiCl4) is hydrolyzed in a flame under the conditions where the flow rate ratio of H2 to O2 is controlled to 0.5-2.0 and that of H2 to silicon halide to 10-100, and the obtained fine SiO2 particles are deposited to obtain a porous base material. The base material is then allowed to react with a chlorinating agent (e.g. Cl2) at 1,000-1,300 deg.C. The reaction product is dehydrated, then heated at 1,000-1,300 deg.C to remove the residual chlorinating agent, and vitirfied at 1,450-1,550 deg.C. Consequently, the high-purity quartz glass having >=88% transmissivity in the 200-2,500nm wavelength region and without the 2,730nm absorption based on the OH stretching vibration is obtained.

Title: Line segment approximation system
Inventor: IKEDA KAZUHIRO
IPC: G06T3/00
Filed: 1987-12-08
Abstract: PURPOSE:To decrease operation quantity by generating an approximate error in a next segment approximation using approximate errors in a segment approximation processing up to the last time. CONSTITUTION:Since an approximate error E of a segment P1P3 for a contour part P2 is positioned at the left side of the segment P1P3, the approximate error E is added to a larger one (EL1) out of left side approximate errors EL1 and EL2. This added value EL (=EL1+E) is made into the left side approximate error of the contour point P2 by the segment P1P3. Further, when a larger one (ER2) out of right side approximate values ER1 and ER2 of segments P1P2 and P2P3 is made into a right side approximate error ER of the segment P1P3, and when the larger one (value EL) out of the values EL and ER is equal to a reference value ES or above, the approximation of the segments P1P2 and P2P3 by the segment P1P3 is prohibited. Thereafter, the contour point P2 is made into a new first contour point, and the same approximation processing is executed by three contour points, which are contour points P2, P3, and a farther contour point. Thus, the number of the times of an operation can be decreased, and a high-speed segment approximation processing can be attained.
