Title: Grain-oriented silicon steel sheet extremely low in core loss and its production
Inventor: KOMATSUBARA MICHIRO
IPC: H01F1/16
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion of tensile coating film, to operate strong tension and to reduce core loss therein by making the surface of the base of a grain-oriented silicon steel sheet a smooth face having a specified roughness or a crystal orientation emphasizing treated face to form a metallic alloy layer having a specified roughness on the face and forming tensile coating film on the layer. SOLUTION: A grain-oriented silicon steel sheet stock contg., by weight, about 1.5 to 7.0% Si and about 0.03 to 2.5% Mn is treated to a obtain a grain- oriented silicon steel sheet in which the secondarily recrystallized structure in the (110)[001] orientation is developed. The surface of the steel sheet is subjected to smoothening treatment for reducing the average roughness to <=0.20 μm or a crystal orientation emphasizing treatment and is furthermore subjected to domain fractionating treatment. This smooth face or the crystal orientation emphasizing treated face is subjected to metallic plating such as chrome plating. This metal plating layer is applied under the conditions in which the plating layer nonuniformly grows, and the average roughness of the surface is regulated to >=0.20 μm. Next, tensile coating is formed on the metallic plating layer.

Inventor: SUMIGARA NORIYUKI
IPC: G01B3/20
Filed: 1989-11-30
Abstract: PURPOSE:To simultaneously measure the distance from the central point of each of elbows and angle valves of different diameters to an end face by making a centering cone slide while maintaining the center constant in combination of two squares. CONSTITUTION:A centering cone 2 is mounted to each of squares A, B by a guide bolt 3. The squares A, B intersect at right angles to each other via a hollow slide plate 4. This two dimensional measure is constituted in this manner. The centering cone 2 in the direction of an X axis is slid to be in tight contact with a bore, so that the square A is brought in tight contact with an end face. Likewise, the centering cone in the direction of a Y axis is slid. Then, a scale where the squares A, B intersect in the slide plate 4 is read. Accordingly, the distance from the central point to the end face can be directly known simultaneously in two directions.

Filed: 1994-12-15
Abstract: PURPOSE: To efficiently execute dehydrogenation treatment by specifying a thickness of the slag in which the basicity in surface of molten steel held in a vessel is specified, when molten steel is subjected to dehydrogenation. CONSTITUTION: After the molten steel treated in decarburization furnace is transferred to a ladle and is subjected to component adjustment, the steel is subjected to dehydrogenation treatment via dephospherizing and desulpherizing treatments.

Title: Stabilized direct-current power supply
Inventor: INOUE NAOYUKI
IPC: H02M3/00
Filed: 1994-12-15
Abstract: PURPOSE: To obtain a stabilized direct-current power supply having high output accuracy, by adding the difference between a reference voltage output from a DC-DC converter and that generated from a reference voltage generator to a supply voltage, and supplying a feedback input terminal with the result. CONSTITUTION: A DC-DC converter 18 regulates an externally supplied direct- current supply voltage and converts it into a direct-current supply voltage according to the difference between a voltage applied through a feedback input terminal 12 and an internally obtained reference voltage. The converter then outputs the result to the outside through a power supply output terminal 14. It also outputs an internally obtained reference voltage through a reference voltage output terminal 16. A reference voltage generator 20 accurately generates another reference voltage of the same value as that of the DC-DC converter 18.  A feedback voltage corrector 22 adds the difference between that reference voltage and that output through the reference voltage output terminal 16 on the DC-DC converter 18 to a direct-current supply voltage output through the power supply output terminal 14, and supplies the feedback input terminal 12 with the result. This obtains a stabilized direct-current power supply having high output accuracy.
