Abstract: Provided are a magnetic tunnel junction dement suppressing diffusion and penetration of constituent elements between a hard mask film, and a magnetic tunnel junction film and a protection layer, and a method for manufacturing the magnetic tunnel junction element. The magnetic tunnel junction element has a configuration in which a non-magnetic insertion layer (7) including Ta or the like is inserted beneath a hard mask layer (8).

Abstract: An apparatus for producing containers made of paper-base laminate, the apparatus comprising: an intermittently drivable rotor 42 having radial mandrels 43 each adapted to support a tubular container blank of square to rectangular cross section as fitted therearound, the mandrels 43 being so arranged as to successively stop at each of processing stations I to VI including a pressure bonding station V, and a bottom bonding unit 48 disposed at the pressure bonding station V, each of the mandrels 43 having in a forward end face 54 thereof a groove 55 for forming the recess 36, the bottom bonding unit 48 comprising a bonding member 52 having a pressing face 56, the pressing face 56 being opposed to the forward end face 54 of the mandrel 43 as stopped at the pressure bonding station V, the pressing face 56 being provided with a ridge 57 corresponding to the groove 55.

Abstract: A paper-base laminate container having a bottom closure formed with a recess. The recess has an inverted V-shaped cross section and extends across the bottom closure through the center thereof for positioning the container upright with good stability.

Abstract: A blank feeder is used for feeding blanks to a bottom forming mandrel. The blanks are initially in a flat form and are unfoldable to a form of square cross section. The feeder includes a magazine for the flat blanks, and a transport arrangement having a path of transport extending from the delivery opening along a circular arc having a central axis parallel to the widthwise direction of the blank in the delivery opening. The transport arrangement includes a suction member, a transport arm carrying the suction member on a forward end, and a shaft rotatably supporting the transport arm and having an axis aligned with a central axis of the circular arc. The suction member has suction cups at different distances from the central axis for gripping one side of the blank, so that the blank is unfolded by movement of the suction member along the circular arc causing a greater separation of a gripped side of the blank at the furthest end of the blank from the central axis than at the nearest end of the blank.

Abstract: A blank feeder is disclosed having a magazine with a delivery opening at one end and accommodating flat blanks as arranged from the one end toward the other end thereof in the form of a stack. The blank feeder also has a transport device having a path of transport extending straight from the delivery opening as a starting end to a terminal end away from the opening, and a device for unfolding each of the flat blanks to a tubular form of square cross section while the blank is being transported by the transport device. The unfolding device has first and second blank unfolding claws provided at edge portions of the delivery opening so as to be individually engageable with opposite ends of the blank in the delivery opening. The first and second unfolding claws are positioned at different distances from a reference plane orthogonal to the transport path in a direction along the path.
