Title: Manufacture of stamper for information recording medium
Inventor: KOYAHARA SATORU
IPC: G11B7/26
Filed: 1986-12-25
Abstract: PURPOSE:To form stampers of different diameters on one piece of substrate and to drastically reduce production cost by recording information for different diameters in the inner and the outer circumferential 1 parts of the substrate, and forming stampers, thereafter separating the inner circumferential part from the outer circumferential part. CONSTITUTION:A flat substrate 1 is coated with a photoresist 2, and set on a master disk recorder, then irradiated with a laser beam by a recording head part 3, and thus a guide groove or information for small-diameter disk is recorded in the inner circumferential part 4. Thereafter, in the outer circumferential part 5, a guide groove or information of large diameter is continuously recorded, and the master disk is completed. From this completed disk, a stamper 6 is formed. This stamper 6 is separated into the inner part 4 and the outer part 5 to generate a stamper 7 for five inch optical disk and stamper 8 for twelve inch disk. In such a way, from one kind of substrate, both stampers 7, 8 for small diameter and large diameter can be generated, hence the production cost can be drastically reduced.

Abstract: PROBLEM TO BE SOLVED: To ensure safety at the time of an abnormal condition by dividing one rotation of a rotor of a compressor into a plurality of zones, detecting rotating speed of a rotor in each zone, and protecting a compressor as well as detecting an abnormal condition of the compressor according to rotating speed. SOLUTION: One rotation of a rotor of a brushless D.C. motor is divided into a plurality of zones, every its zone is caught on the basis of detection of a rotating position (201), a time count Tm of a timer T2 is read in (202), and rotating speed R(i) of the rotor in each zone is calculated (203). When the rotating speed R(i) is calculated, the timer T2 is reset, restart is carried out (204), and it is judged whether or not a difference between the rotating speed R(i) which is calculated presently and rotating speed R0 (i) which is calculated previously is 20rps or more (205). In the case where it is reduced 20rps or more, it is judged that a compression load of a compressor is raised abnormally, rotating speed is reduced, an abnormal treatment is carried out to reduce a suction rate of a liquid refrigerant (206), and a present rotating speed R(i) is renewed and memorized as Ro (i).

Title: Method of detoxicating waste water containing element mercury
Inventor: BUINFURIITO KURAI
IPC: C02F1/72
Filed: 1988-12-12
Abstract: To remove, in particular, elemental Hg from waste waters (effluent) from battery factories, from chlor-alkali electrolysis and from electroplating plants, a suitable preliminary stage is their oxidising treatment with H2O2 in the presence of readily available and cheap compounds of iron or iodine which, as catalysts, enable the reaction of Hg with H2O2 to give a precipitatable Hg compound within an acceptable time for practical operation. After precipitation of the Hg as a relatively insoluble compound and filtration, the waste water solution is brought into contact with MnO2, excess H2O2 decomposing to give H2O and O2, and then led to a Hg-selective ionexchanger, which traps any residual quantities of Hg. Water thus detoxified is not burdened with significantly any byproducts formed during the treatment.
