Abstract: A manufacturing method of a semiconductor device includes preparing a semiconductor substrate having a plurality of element regions and having a first surface and a second surface opposite to each other, forming a crack extending in a thickness direction of the semiconductor substrate along a boundary between the plurality of element regions by pressing a pressing member against the first surface of the semiconductor substrate along the boundary, forming a metal film over the plurality of element regions on the first surface of the semiconductor substrate after the forming of the crack, and dividing the semiconductor substrate and the metal film along the boundary by pressing a dividing member against the semiconductor substrate along the boundary from a direction facing the second surface of the semiconductor substrate after the forming of the metal film.

Abstract: Provided is a vehicle seat having a pitching function, which not only has an assist function for bringing a main frame to a seated position or a forward tilted position, but also prevents the increase in the width and the increase in the weight of the seat. The vehicle seat includes: a base frame; a main frame disposed on the base frame and having a back frame and a cushion frame; and a link mechanism that allows the main frame to swing to the seated position and the forward tilted position with respect to the base frame. A third rotating shaft of the link mechanism is provided with a torsion spring that urges the main frame to swing from the forward tilted position to the seated position.

Abstract: A vehicle seat (10) has a seat cushion (20) and a seat back (30), which are affixed to the body of a vehicle. The seat back (30) has: a first member (50) which is formed in a plate-like shape; and a second member (60) with a hat-shaped cross-section, which is configured so that a flange section (61) is in contact with one surface, in a thickness direction, of the first member (50). A center bead (52) is provided at the center portion of the first member (50). The center bead (52) is configured so that a longitudinal end of the center bead (52) and the second member (60) are overlapped in a plan view viewed in the thickness direction of the first member (50). As a result, the first member (50) of the seat back (30) is prevented from being deformed at the longitudinal end of the center bead (52).

Abstract: An armrest for a vehicle seat that is rotatable with respect to a seat back of the vehicle seat, and the armrest includes a bracket that is configured to support a rotation shaft of the armrest, the hollow plastic shell to which the bracket is joined and a trim cover that covers the hollow plastic shell.

Abstract: In an HD-DVD, record densities are different between in a lead-in area and in a data area. On the other hand, in a DVD, the record densities of a lead-in area and a data area are equal. In discriminating an optical disc between the HD-DVD and the DVD, a light beam having a wavelength for the HD-DVD or for the DVD is projected onto the respective areas of the lead-in area and the data area, and a comparison is made between the amplitude of a tracking error (TE) signal obtained on the basis of reflected light from the lead-in area and that of a TE signal obtained on the basis of reflected light from the data area. When the difference between both the amplitudes is within a predetermined range, the optical disc is discriminated as the DVD, and when the difference between both the amplitudes is larger than the predetermined range, the optical disc is discriminated as the HD-DVD.
