Patent number: 6398623Abstract: A working method capable of implementing various types of devices such as a slider available with high reliability without causing malfunction or the like due to contamination during an actual use is provided by solving a problem of deterioration in profile precision and a problem of contamination resulting from roughness of a cut surface or chipping. A wire saw comprising a wire having a diameter greater than a width of a portion cut by a first cutting step, namely, a width of a cut groove is brought into contact with the cut groove of a bar. While the wire saw is slid in a longitudinal direction, the bar is sliced across the overall thickness of the bar along the thickness of the bar. Thus, while the bar is cut, a final cut surface formed by cutting is smoothed.Type: GrantFiled: March 30, 2000Date of Patent: June 4, 2002Assignee: TDK CorporationInventors: Osamu Fukuroi, Ryuji Fujii

Patent number: 6371101Abstract: A slicing device using yarn includes at least two yard-guide cylinders on which the yarn is wound and by which the yarn can be moved with a reciprocating or continuous motion pressed against a piece to be sliced fixed on a supporting table. The yarn is wound on the yarn-guide so as to form at least two layers of yarn intersecting with one or several non-null intersecting angles (&bgr;) and so as to pass in a straight line from one cylinder to the other. The angle of inclination between the moving direction of the piece to be sliced and a line perpendicular to the plane of the yarn cylinder axes is adjustable so as to obtain strictly parallel slices. The intersection of the yarn layers improves the quality of slices obtained by facilitating the subsequent mechanical treatment operations of surfaces with crossed faults. Moreover, the angle of the yarn layers reduces the shearing and torsional stresses on the support of the piece to be sliced when the slices are being cut.Type: GrantFiled: November 8, 1999Date of Patent: April 16, 2002Assignee: HCT Shaping Systems SAInventor: Charles Hauser
