  • Publication number: 20090149002
    Abstract: First, mapping data storing interrupted areas is obtained. In a first modified-layer forming step, before a stacked article is stacked on a front surface of a substrate, a laser beam is directed to the interrupted areas based on the mapping data to form modified layers only at the interrupted areas. After the stacked articles have been stacked on the substrate, in a second modified-layer forming step, the laser beam is directed at least to the predetermined dividing line formed with no modified layer in the first modified-layer forming step to form a modified layer.

  • Patent number: 7336782
    Abstract: A wiring device is used in a folding portable device including a hinge unit permitting an upper unit to fold/unfold and/or to rotate with regard to a lower unit. The wiring device comprises a rotative direction wound portion having a first central axis corresponding to a rotating axis of the hinge. A folding/unfolding direction wound portion has a second central axis corresponding to a folding/unfolding axis of the hinge. A FPC fixing member fixes a FPC holding member holding a predetermined part of a FPC to the hinge. The rotative direction wound portion is wound with a first part of a flexible printed cable that is continuous with one end of the predetermined part. The folding/unfolding direction wound portion is wound with a second part of the flexible printed cable that is continuous with the other end of the predetermined part.

  • Patent number: 7320153
    Abstract: A fold-type cellular phone has a top unit, a bottom unit and a hinge coupling together the top unit and the bottom unit while allowing the top unit to turn and swivel with respect to the bottom unit. The top unit is first unfolded from a first folded position to an attitude angle of 160 to 170 degrees, and swiveled by 180 degrees to be folded onto the bottom unit in a second folded position at an attitude angle of 180 degrees. The swivel movement of the top unit causes a cam assembly to turn the top unit from the attitude angle of 160-170 degrees to an attitude angle of 180 degrees in the second folded position, thereby allowing the top unit to assume a suitable attitude with respect to the bottom unit.
