Title: Holding method in case of tensioning metal thin plate
Inventor: ISHIKAWA TORU
IPC: G01N3/04
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of a metal thin plate by slipping of a holding member by providing a gap between the end face of the metal thin plate and the holding member to hold the inside part of the metal thin plate when the metal thin plate is tensioned through the holding member in a prescribed direction. SOLUTION: The holding device 3 of a tension test device 1 is composed of e.g. right and left holding members (pushing member) 4, a receiving member provided downward thereof corresponding to the holding member 4, and a tension drive device pushing the holding member downward and moving outward. The holding member 4 is constituted of an elongated angular column and the like along the end face of a metal thin plate, and when the metal thin plate 2 of thickness of 50 μm or thinner is pulled outward, the end face of the holding member 4 is matched inwardly by a prescribed width (gap) (b) from the end face of the thin plate 2 to be held.  Thereby even if tension is performed by force of 1/2 or larger of rupture stress of the metal thin plate 2, because large friction resistance force is developed between the corner C of the outside of the holding member 4 and the surface of the thin plate 2, a slip between the thin plate 2 and the holding member 4 does not occur and rupture does not occur. Thus, tension test can be surely performed.

Title: Production of liner sheet
Inventor: KANO KENICHI
IPC: G11B23/033
Filed: 1985-09-18
Abstract: PURPOSE:To prevent the fraying of fibers by pressurizing a peripheral edge part including the cut part of a line sheet material film consisting of a nonwoven fabric and cutting the pressurized part thereafter. CONSTITUTION:A liner sheet material film 12 is attached to a pressing device 13 and is heated by an ultrasonic heater incorporated in the device 13 and is punched with a punch cutting blade 17 by a die 16 while welding fibers. Since the material film 12 is so pressurized that the nonwoven fabric of the material film 12 is welded, the occurrence of fraying of fibers and a fiber layer in the punch-cut part is prevented when the material film 12 is cut by the cutting blade 17. Since fibers of the nonwoven fabric are welded to a cut part side edge 18 which is the outside peripheral edge of a punched liner sheet 10, fibers are not newly frayed from the cut part side edge 18 when the liner sheet 10 is attached to a disc cartridge.
