Abstract: PURPOSE:To prevent generation of a fish tail, by forging front and rear ends of a steel billet from top and bottom and from lateral both sides with a press head of a prescribed shape, in order to form a protuberance in a prescribed shape in each of front and rear ends. CONSTITUTION:A steel billet blank 3 cut into a prescribed length is heated in a heating furnace 7 and is then conveyed and located by a roller table into a prescribed position; then, the front and rear ends of this billet blank 3 are forged by a forming press 9 in which the middle part is formed into a parallel flat shape and both ends are formed into a curved surface or an inclined surface. Hereby, each of front and rear ends of the billet blank 3 is formed into a protuberance having a shoulder part and a bulging part 6, and a cross sectional area smaller than that of the blank billet 3. Thus prepared blank billet 3 is then subjected to the first bloomer 14, the second bloomer 15 or a continuous rolling mill 16, and is thereby formed into a desired square or round billet.

IPC: B65H29/70
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To absorb, correct and prevent curl and distortion by intentionally producing a gentle circular arc curl in the orthogonal direction of a sheet vertical texture direction by guiding a sheet on which a curl phenomenon is generated inbetween a sheet upper surface high heat source and a sheet lower surface low heat source. SOLUTION: A sheet Y1 in a state where a curl is produced by receiving fixing heat of a heating roller A1 is introduced to a curl correction and prevention device 1. A gentle circular arc curl is intentionally added in the orthogonal direction of a sheet vertical texture by passing the sheet Y1 in a temperature difference between an upper surface high heat source 5 and a lower surface low heat source 6 on this curl correction and prevention device 1. Consequently, production of the curl is obstructed and prevented by reinforcing a straight line in the vertical texture direction by a gentle circular arc intentionally added in a course direction, and it is also possible to correct and prevent the course direction as tensile force of a gentle circular arc protruded surface intentionally added.

Title: Magnetizing device for magnetic scale
Inventor: OSHIMA HISAO
IPC: G01B7/00
Filed: 1987-04-06
Abstract: PURPOSE:To perform magnetization to large residual magnetism intensity which are equal to or nearly equal to saturation values of respective magnetic poles by carrying out repetitive magnetization plural times by the respective magnetic poles and making the exciting force of a yoke for the repetitive magnetization to the same magnetic pole smaller than in last magnetization. CONSTITUTION:When the periphery of a rotor 2 is magnetized while divided equally by (n) (n: natural even number), the rotor 2 is magnetized by the yoke 11 which produces a magnetic field intense enough to saturate the magnetic poles of the rotor 2 while rotated successively, only the last (n)th magnetic pole is saturated after one round, and other magnetic poles are all unsaturated. Then when magnetization in a 2nd round is performed, the magnetic field intensity for the magnetization is small enough not to eliminate the residual magnetism of the last magnetization or not to decrease it greatly. Thus, while the magnetic field is made weaker round by round, the magnetizing operation is repeated and an exciting force which does not reduce the residual magnetism of following magnetic poles in series is used for the magnetization to nearly eliminate variance in surface magnetic density among all the magnetic poles, thereby performing the magnetization so that the magnetic flux density of the respective magnetic poles is large.

Abstract: PURPOSE:To easily pass the magnetic fluxes of a magnetic circuit and to assure high reproducing efficiency by constituting the magnetic head in such a manner that the axis of easy magnetization of a 1st laminate coincides with a gap depth direction and the axis of easy magnetization of a 2nd laminate intersects orthogonally with the easy axis of the 1st laminate. CONSTITUTION:The magnetic metallic material films of central cores 2a, 2b are provided with the respective axes of easy magnetization in parallel with the butt surfaces of the core forming a gap 1 and the magnetic permeability thereof is larger in the direction orthogonal with the butt surfaces of the core. The magnetic metallic material films of outer cores 3a, 3b are provided with the respective axes of easy magnetization in the direction orthogonal with the axes of easy magnetization of the central cores 2a, 2b. The magnetic permeability, therefore, increases in the direction orthogonal with the axis of easy magnetization if the axis of easy magnetization is imparted to the magnetic material. The magnetic fluxes flow always in the direction of the higher magnetic permeability with respect to the central cores and the outer cores. The reproducing efficiency is thus improved.
