Title: Rotary drill head finely adjustable by fluid in direction vertical to rotary shaft of rotating drill rod
Inventor: BUIRUFURIITO GERUKU
IPC: B23B29/034
Filed: 1993-06-04
Abstract: PURPOSE: To move a movable body substantially in parallel by connecting the movable body, a ram, and a drill rod in a non-friction manner mutually. CONSTITUTION: Since the elongation on a thin wall part 64 side of a drill rod 12 and the compression on a thin wall part 65 side of a ram 26 are larger than those on thick wall part sides of each when pressure medium acts in a rotating drill head 10, the ram 26 is curved to the thin wall part 65 side, and the drill rod 12 is curved to the thick wall part side. Here, since the curve line of the ram 26 coincides with the curve line of the drill rod 12 completely or substantially completely, a force vertical to an axis does not occur at all or slight force only occurs between the ram 26 and the drill rod 12. As a result, a position of a cutting bit 18 is displaced in a scope of μm on a trajectory which is curved and extended in arrow 63 direction vertical relative to a rotary shaft 70 from a stationary position due to the action of pressure medium.  The displacement of the cutting bit 18 is larger than a distance at which the center of the movable body 28 moves due to pressure change for a fixed member 11 as a base.

Title: Preventing method for flying of strip tip in rolling line
Inventor: MIZUTA KATSUNORI
IPC: B21B39/12
Filed: 1978-11-01
Abstract: PURPOSE: To prevent the flying of the strip tip, and to increase the speed of sheet pass, by installing the segmental hot run table being supported so as to be inclinable between the final stand and the coiler's pinch roll, and by running this table according to a specified method.  
     CONSTITUTION: The hot run table 3 is installed between the final stand 1 and the pinch roll 2 of the coiler 5. The table 3 is constituted so as to independently, inclinably support both ends of each segmented table 3 1  by the cylinders 4. At running the strip, the cylinder 4 is inclined stepwise in order to lower the side of the roll 2 over a section of 10m before the roll 2; and this section is returned to horizontal state when the strip tip arrives at the position 10m before the pinch roll 2. The strip tip is smoothly bitten by the roll 2 without causing flying because of the resultant force of the thrust force in the running direction and the downward load. When the strip tail goes out of the stand 1, above stated inclination is reversed.

Title: Steel sheet excellent in surface property
Inventor: IMAI NORIO
IPC: B22D11/00
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To obtain a steel sheet free from flaws caused by surface cracking in continuous casting and excellent in surface properties by allowing it to contain specified weight ratios of chemical components such as C, Si, Mn, Al and N. SOLUTION: This steel sheet has a chemical compsn. contg., by weight, <=0.2% C, 0 to 2.0% Si, 0.05 to 2.0% Mn, 0.3 to 2.5% Al and 0.002 to 0.01% N. The coarsening of AlN in the grains in a low temp. γregion is promoted to suppress then hardening in the grains, the difference in the strength with nonsegregated zones in the vicinities of the grain boundaries is eliminated, and the concentration of strains on the nonsegregated zones is suppressed to prevent the embrittlement therein. In the α+γ regions, the formation of ferrite onto the grain boundaries is suppressed by Al, the conversion into film-shaped ferrite is suppressed, the amt. of ferrite increases, and the concentration of strains is suppressed to prevent the embrittlement therein.  In this way, the maintenance of a slab before hot rolling is made needless, so that the working cost and the energy cost can be reduced. In the case the strength and formability of the steel sheet are required, Nb, V, Cr, Mo, Zr or rare earth elements may be added thereto.

Abstract: PURPOSE:To automatically control such a complicated shape defect as composite elongation, and to obtain a flat shape, by installing plural shape detectors on the run-out side of a rolling roll, and by operating the detected values for the purpose of separately adjusting plural cooling-and-heating devices. CONSTITUTION:Plural shape detectors 3 are arranged at a uniform interval on the run-out side of a rolling mill; the outputs of these detectors 3 are inputted to an input processor 5 and are therein converted to elongation which is then compared with the reference elongation. On the basis of distribution of thus obtained deviation of the elongation, the cooling rate and heating rate of plural cooling-and-heating devices 4 for the rolled material are operated for every section of the breadth of the rolled material. The result of this operation is inputted to an output unit 7 which then outputs the cooling rate and heating rate of plural cooling-and-heating devices 4 by using an influence factor stored in a memory unit 6; hereby, the shape of the rolled material is controlled. By the present control system, plural cooling-and-heating devices 4 are separately controlled and a product with required flat shape and thickness is obtained.

Filed: 1985-06-21
Abstract: PURPOSE:To enhance positional accuracy of a ribbon and enable favorable printing, by providing a support 2 for a cassette casing 1 so that it can perform a parallel movement in the vertical direction. CONSTITUTION:When a gear 5 is rotated forward or reversely by driving a pulse motor 13, a rack 6 is horizontally moved forward or backward. Then, slide pins 8 slide in slots 7 while pushing rocking arms 3, whereby the arms 3 are vertically turned while maintaining parallelism, since straight lines connecting the pins 8 and the centers of turning of the arms 3 form a parallelogram. By this, shift pins 17 are vertically turned while sliding in a slide hole 4 provided in the support 2. Since straight lines connecting the pins 17 and said centers of turning form a parallelogram, the support 2 performs a parallel movement in the vertical direction. With the support 2 vertically moved, a ribbon fitted to a ribbon guide 25 is vertically moved without slanting between a platen 10 and a printing head, so that the ribbon is prevented from being caught by the head, and the position of the ribbon can be securely shifted.
