Abstract:
A method of carrying out laser processing on a wafer having a plurality of parallel streets on the front surface along the streets, comprising the steps of: carrying out a first laser processing step of carrying out laser processing along streets formed in one half area of the wafer by carrying out a laser beam application step for applying a laser beam along the streets by positioning the outermost street on one side in the indexing-feed direction of the wafer right below a condenser and an indexing-feed step for positioning a street adjacent to the street which has undergone the laser beam application step on the wafer right below the condenser sequentially; and carrying out a second laser processing step of carrying out laser processing along streets formed in the other half area of the wafer by carrying out a laser beam application step for applying a laser beam along the streets by positioning the outermost street on the other side in the indexing-feed direction of the wafer which has undergone the first laser processing step right below the condenser and an indexing-feed step for positioning a street adjacent to the street which has undergone the laser beam application step on the wafer right below the condenser sequentially.
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.
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.
