Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a temperature measuring method and a device capable of accurately detecting the temperature of a substrate from the position of the substrate in an oven. SOLUTION: When a substrate 3 is mounted on a conveyer 4, an inlet sensor 21 detects the tail side 3a of a substrate 3 as a reference position of the substrate and starts measuring the temperature of the substrate.

Title: Video signal conversion method
Inventor: TAKADO SEIICHI
IPC: H04N9/67
Filed: 1994-09-21
Abstract: PURPOSE: To execute signal conversion of a video signal by software. CONSTITUTION: A horizontal synchronizing signal is detected out of the data of a luminance signal by the blanking detection processing of an ST1 by using the digital data of the luminance signal Y and a carrier color signal C sampled by the quadruple frequency of color subcarrier frequency. A pedestal level is detected by the pedestal level detection processing of the ST2. On the basis of this pedestal level, luminance signal component data is demodulated from the data of the luminance signal by the luminance signal demodulation processing of the ST3. The data of the burst signal of the carrier color signal is read in by the color burst signal detection processing of the ST4. On the basis of this data and the data of the scanning period of the carrier color signal, orthogonal component data is obtained by the color signal extraction processing of the ST5.  The orthogonal component data is converted into the color signal component data of I, Q axes by the I, Q axes coordinate transformation processing of the ST6. A three primary colors signal is formed from this color signal component data and the demodulated luminance signal component data by the three primary colors signal conversion processing of the ST7.

Title: Infrared-heated single crystal producing device
Inventor: TAKASU SEIICHI
IPC: C30B13/16
Filed: 1989-08-31
Abstract: PURPOSE:To improve the quality of a single crystal by arranging a light shielding ring enclosing a part to be heated close to the solid-liq. interface of a heating part on the crystal side, setting a heat shield surrounding a crystal rod below the ring and providing a driving mechanism for vertically moving the ring and shield independently. CONSTITUTION:The IR rays from the IR lamps 13 and 14 arranged at the focuses F1 and F2 of ellipsoidal mirrors 11 and 12 are condensed on the part 15 to be heated at the focus F0 to heat the part 15. The lower end of a raw material rod 17 and the upper end of the crystal rod 19 are heated by the radiation energy due to the heating and brought into contact with each other to form a melt zone at the part 15. At this time, since the part 15 close to the solid-liq. interface on the crystal side is shaded by the light shielding ring 22 from the IR rays irradiation, IR rays does not absorb, the temp. gradient is sharpened, and the high-temp. region is narrowed. A large-diameter crystal is grown since the part 15 is stably maintained. The rod 19 is shielded from IR rays by the heat shield 23, hence IR rays does not absorb, the radiant heat from the rod 19 is intercepted by the shield 23 to keep heat insulation, and a large-diameter crystal is grown. Furthermore, the single crystal growth condition is optimally controlled by vertically moving the ring 22 and the rod 23.
