Filed: 1989-11-20
Abstract: PURPOSE:To save manpower in the operation of a furnace and stabilizing the quality of a product based on the stable amount of melting and the stable melting temperature of copper by controlling the melting depending upon a retaining amount and its variations with time. CONSTITUTION:Three or more membership functions from NB(negative big) to PB (positive big) are set at a fuzzy inference section with respect to the deviation E between a desired retaining amount and an actual retaining amount and also the variation DELTAE of the deviation with time, and the variation amount of a combustion level at the time of respective combination is determined. A new combustion level is set by integrating the variation amount determined by the fuzzy inference to the combustion level under actual condition. The combustion level preset by a fold-line function on the basis of the combustion level determined by the fuzzy inference section is converted into an air pressure in each zone according to the relation with the air pressure in each zone. Then, a coefficient that varies stepwise with respect to the melting temperature of copper is set for each zone, and this coefficient is multiplied by the air pressure in each zone, which has been found previously, to make a correction and to set a final burner air pressure.

Abstract: PURPOSE:To make a magnetic disc highly dense and to improve the reliability of the disc by processing the surface of a substrate to have minute recesses and protrusions by a texturing treatment, and then processing by a discharging treatment, thereby to form a recording magnetic thin film and a protecting lubricating film. CONSTITUTION:A texture part 2, a recording magnetic thin film 3 and a protecting lubricating layer 4 are formed on a smooth substrate 1 of Al-Mg, glass or the like. The texturing part 2 is obtained by forming grooves in the same direction by means of a so-called lapping tape which is fixed by a binder with using Al2O3, Fe3O3 etc. as an abrasive material. After the minute recesses and protrusions are formed, the texturing part is subjected to a discharging process, so that the recording magnetic thin film 3 and the protecting lubricating film 4 are formed. Therefore, the detachment of the recording magnetic thin film part 3 which is extraordinarily promoted from cores of steep protrusions as local defects of the minute recesses and protrusions formed in the texturing process can be eliminated. Accordingly, a reliable magnetic disc for high-density recording can be obtained.

Abstract: PURPOSE:To increase the discharging speed over wide range from low vacuum to high vacuum, by tapering the inner circumferential face of stator and the outer circumferential face of rotor with same gradient and enabling control of motion in the axial direction for maintaining the gap constant by means of a sensor signal. CONSTITUTION:When a rotor 3 is rotated with high speed by means of a motor 14 and the gap 8 between a tapered inner circumferential face of a stator 2 decreases because of centrifugal force or thermal expansion, a sensor 10 detects the condition and a servo motor 11 is driven by a control signal fed from a controller 12 to move a bearing box 6b downward through a thread coupling 13 so as to move the rotor 3 through an upper bearing box 6a which is moved downward by means of a spring 7a corresponding to the downward motion of the bearing box 6b and a shaft 9 thus maintaining the gap 8 constant. Consequently, a constant gap 8 is maintained at all times thereby the rotor and the stator do not contact even if said gap is very small and a high discharging speed can be obtained over a wide range from low vacuum to high vacuum.

Title: Magneto-optical recording medium
Inventor: WASHIMI SATOSHI
IPC: G11B11/105
Filed: 1989-11-20
Abstract: PURPOSE:To prevent deterioration of a medium due to temp. by alternately depositing layers of Pt layer and Fe-Co alloy layer containing 5-40 atomic% Fe atoms to Co atoms. CONSTITUTION:On a substrate 1, there are alternately deposited layers of Pt layer 2 having 17 A thickness and Fe-Co layer 3 having 5 Angstrom  thickness. These layers are repeatedly laminated to the end layer of Pt layer 2 on the opposite side to the substrate to obtain the total thickness of 215 Angstrom . The proportion of Fe atoms in the Fe-Co layer 3 is about 5-40 atomic% to Co atoms. If Fe exceeds 40 atomic%, the Kerr rotation angle decreases, while with less than 5%, deterioration of Kerr rotation due to temp. elevation can not be prevented. By this method, deterioration of Kerr rotation due to temp. elevation can be suppressed and reproduction signal characteristics can be improved.
