Title: Preparation of dithionite
Inventor: ARAKAWA SATOSHI
IPC: C01B17/66
Filed: 1981-11-09
Abstract: PURPOSE:To prepare a high-purity product in high yield, by adding an epoxy compound and an acidic substance to a filtrate from which crystal of precipitated dithionite is separated or to a washed solution of the crystal, reusing it for  the preparation of the titled salt. CONSTITUTION:HCOONa or HCOOH is reacted with an alkalifying agent such as NaOH, etc. and SO2 in water-organic solvent to synthesize Na2S2O4 and the reaction solution is cooled to precipitate the crystal of Na2SO4. An epoxy compound is added to a filtrate from which the crystal is separated or a washed solution of the crystal, Na2S2O3 in the solution is converted into a harmless substance, and an acidic substance is added to the solution so that the precipitation of the crystal taking place in the cooling is prevented or the precipitated crystal is dissolved. The solution having an extremely small amount of crystal thus obtained is circulated for the preparation of Na2S2O4 and reused.

Title: Stabilization of recording and erasing states
Inventor: ONISHI TOSHIICHI
IPC: G11B7/246
Filed: 1988-07-20
Abstract: PURPOSE:To prevent erroneous recording and erroneous erasing and besides, to obtain excellent durability against repetitive recording and erasing by a method wherein recording information is fixed by fading light absorbing pigment. CONSTITUTION:An Al reflecting film 8 is established on a glass substrate 9. A polymer liquid crystal and a light absorbing pigment expressed by a structural formula II are applied thereon and are heated and dried to prepare an optical recording medium 3. Then, ultraviolet laser beam is repetitively irradiated onto a specific area of a recording layer 2 with a laser 16, and the light absorbing pigment in this area is faded. Though light reflectance is increased by decrease of light absorbing intensity in this area after fading, since it is not varied exceeding a level of a photodiode identifying a recording state and an erasing state, information can be reproduced. Further, though recording light or erasing light is applied to a light fading area, light dispersion intensity of polymer liquid crystal in the recording layer is varied, and recording or erasing can not be performed. Furthermore, though recording and erasing are repetitively performed in an unfixed recording layer area, a reproductive contrast ratio is not varied.

Title: Control method for reversible rolling mill
Inventor: YAMAMOTO AKIYOSHI
IPC: B21B37/46
Filed: 1986-07-29
Abstract: PURPOSE:To prevent a rolling motor becoming impossible to roll due to the temp. rise by controlling a rolling stage by finding the rolling schedule satisfying both the allowable rolling power and allowable motor temp. rise limit together and making the rolling time minimum. CONSTITUTION:The optimum rolling schedule is decided from the various allowance values of pass times, load distribution and a reversible rolling mill 1 in an arithmetic unit 11 and the set value of each pass is found with these operations. Each arithmetic value is found by repeating the operation so that the temp. rise limit of a motor 4 and rolling power may be attained to <= the allowable value. The found value is set as the optimum schedule value if the found motor temp. rise limit be within the allowable range of the rolling motor 4 and in the case of being out of the allowable range the time for the no-load idle state close to zero at continuous electrification saturation temp. is extended and the motor temp. rise value falls, so recalculation is performed by varying this no-load idle time and the optimum rolling schedule is decided.

Title: Pattern position measuring apparatus
Inventor: OTSUKA HIDEO
IPC: G01B21/00
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To correct pattern position correctly by correcting a detected pattern position based on a flexural profile occurring in a substrate having a protective member supported by a supporting member. SOLUTION: Scattering light detectors 50a-50d detect scattering light generated at the pattern edge of a substrate 10 having a pericle and transmit an edge detection signal. Interferometers 14a, 14b for X and Y axes detect a position in the direction of X and Y axes on the surface of the substrate 10 and transmit a position detection signal of an XY stage 15. A main controller detects a plurality of patterns on the substrate 10 as a two-dimensional pattern position based on the edge detection signal and the position detection signal. The height h from the reference surface of the XY stage 15 to the surface of the substrate 10 is detected, based on the movement in Z direction of an objective lens 11 when it is focused to the surface of the substrate 10.  Based on the difference of the height h from that detected at a specified position on the substrate 10, the main controller determines the flexure Δhpm of the substrate 10 and corrects a pattern position detected in actually measured flexure profile [Δhpm].
