  • Publication number: 20040248719
    Abstract: An object is to provide a preforming apparatus allowing smooth travel of a packaging material (11). The preforming apparatus includes first to fourth guides (34 to 37) for forming a web-like packaging material (11) into a tubular packaging material (11); a longitudinal sealing device (41) for longitudinally sealing the tubular packaging material (11); a drive unit; and a tube guide device (38) disposed in such a manner as to surround the tubular packaging material (11), and guiding the tubular packaging material (11) while being driven by means of the drive unit. Activation of the drive unit causes the tube guide device (38) to guide and feed the packaging material (11), thereby preventing the tube guide device (38) from resisting travel of the packaging material (11). Thus, the tube guide device (38) does not yield a braking effect, thereby allowing smooth travel of the packaging material (11).

  • Patent number: 6584045
    Abstract: The conductor pattern of a magnetic head coil includes a spiral coil pattern to which a current can be supplied to flow around the magnetic field generation center, and a conductor pattern which is formed outside the coil pattern and cannot receive a current so as to flow around the magnetic field generation center. Letting S be the distance from the outer edge of the outermost periphery of the coil pattern, and P be the pitch, a conductor occupation ratio R of a conductor pattern formed outside the coil pattern simultaneously satisfies inequalities 1 to 3, and the conductor pattern does not form any closed loop surrounding the coil pattern in a first region A1 given by inequality 1: Inequality 1: 0≦R≦0.3 in the first region A1 where 0≦S≦1.5P Inequality 2: 0≦R≦0.8 in a second region A2 where 1.5P<S≦6.0P Inequality 3: 0.3<R≦1 in a third region A3 where 6.
