Title: Protective device for power converter
Inventor: MOZE TADAO
IPC: H03K17/08
Filed: 1988-04-06
Abstract: PURPOSE:To isolate faulty section reliably, by connecting a series circuit of a capacitor and a semiconductor switch in parallel with a protective device for separating the faulty section, upon occurrence of fault in a power converter having main circuit constituted with semiconductor elements, and discharging the capacitor. CONSTITUTION:Output from a DC power source 10 is fed through a protective fuse 7 to a power converter A, which produces AC power for driving a load 9. A series circuit of a thyristor 13 and a capacitor 12 is connected in parallel with a protective fuse 7, where the capacitor 7 is charged previously through a resistor 14. When an excessive current Is flows through the power converter A due to fault of the load 9, a CT16 detects the excessive current and the thyristor 13 is energized then the capacitor 12 is discharged thus lapping current Ic over the current Is. Consequently, the fuse 7 is blown off reliably even by such fault current Is as having magnitude insufficient to blow off the fuse 7, resulting in reliable protection of the converter A.

Title: Magnetic disk device
Inventor: IMASHIRO AKIHIKO
IPC: G11B17/34
Filed: 1987-04-03
Abstract: PURPOSE:To extend the life of a magnetic disk by varying an edge width of a constrained plate for contacting with a magnetic disk in accordance with the radial distance of the magnetic disk and keeping a contact pressure constant even if the magnetic head moves in the radial direction. CONSTITUTION:The magnetic disk 3 is rotated by the rotation movement of a center hub 2. A magnetic head 4 acts for the magnetic recording/reproducing, contacting with the disk 3, and also moves in the radial direction in parallel with the surface of the magnetic disk 3 by a carriage 5. A tip of the magnetic head 4 is positioned lower than an upper surface of the disk 3 at the center hub 2, while the head 4 creates a bend of the disk 3 by elastic deformation, and moreover a pad 6 pushes up the disk 3 from the opposite side of the head 4 to increase a pressing force between the head 4 and the disk 3. At that time, the contact areas of the pad 6 with the disk 3 are only two spots of the edge parts A and C in the vicinity of the same radius with that positioned by the head 4, and because of eliminating the contact area B, the disk 3 has a large contact area with a center surface of the tip part of the head 4, so that the pressing force of the head 4 can be minimized.

IPC: B22D11/10
Filed: 1980-06-21
Abstract: PURPOSE:To produce a titled ingot superior in quality and characteristics by subjecting the molten steel produced to have specific tapping C% in a converter to vacuum deoxidation then to Al auxiliary deoxidation and continuously casting the same at specific speeds while preventing the formation of air bubbles. CONSTITUTION:The molten steel produced to have product target C%+0.02- 0.05% tapping C% in a converter is subjected to vacuum degassing treatment. By this treatment, the deoxidation by C+O reaction is progressed at far as possible in the molten steel under reduced pressure. Thence, further the remained free O is deoxidized by a small amount of Al, to control the entire O at 40-90ppm. Next, this molten steel is continuously cast at >=0.8m/min casting speeds so that the formation of air bubbles by the C+O reaction during casting is prevented. In this case, the mild steel ingot (C<=0.25%) for bars and wires of superior drawability, suitability for cold forging, machineability, etc. is produced by the converter-vacuum degassing treatment-continuous casting.
