Abstract:
A vehicle wheel having a rim and a disk. A disk flange of the disk may have a non-contact portion non-contacting a radially inner surface of the rim, at a radially outer extension of a width center line of a spoke. As a result, the rigidity of a portion of the disk in the circumferential direction of the wheel where the spoke is provided may be decreased compared with a wheel (conventional) where such non-contact portion is not provided. A difference in rigidity of the disk in the circumferential direction of the wheel between a portion where the vent window is provided and a portion where the spoke is provided may be smaller than that in the case of the conventional wheel, whereby a durability of the wheel and a run-out accuracy of the wheel may be improved.

Abstract:
A method comprising: a step of preforming a plurality of bulging portions on a substantially circular plate blank, the bulging portions being located concentrically and circumferentially outward of a bolt hole, each of the bulging portions being a base of a reinforcing portion of a spoke; a step of forming a plurality of prototypical decorative holes on the respective bulging portions to form a prototypically-shaped spoke between the adjacent prototypical decorative holes; a step of forming a disk flange by bending an outer circumferential portion of the plate blank, on which the prototypical decorative holes are formed, at a right angle to be substantially parallel to a wheel axial direction, so that an outer periphery of a resultant decorative hole forms an upper end edge of the disk flange; and a step of forming the spoke by providing the prototypically-shaped spoke with the reinforcing portion.

Abstract:
A wheel for vehicle comprising: a rim 2 having a drop portion; and a disk 10 formed integrally from a plate material, the rim and the disk being welded together, wherein the disk has: a hub mounting portion 10a; a plurality of spokes 10b radially extending from the hub mounting portion toward an outer periphery of the disk; and a ring-shaped disk flange 10c that is connected to the spokes through a curved-surface connecting portion R that is formed by bending the spokes at an outer circumferential end thereof in a wheel axial direction, the disk flange extends in the wheel axial direction, and a decorative hole 20 is defined by the adjacent spokes, the hub mounting portion, and the disk flange, and a part that faces a distal end 12 of the spoke in a fitting area between an inner circumferential surface of the rim and an outer circumferential surface of the disk flange is welded.
Abstract:
A terminal apparatus includes requester that requests data used for installed software from an external apparatus, a receiver that receives the data requested by the requester, a storage unit that stores the data received by the receiver, a restoring unit that restores the storage unit to the state at an arbitrary point of time; and a restoration controller that enables or disables the restoration operation of the restoring unit, wherein the storage unit stores the data that is requested by the requester and received by the receiver after the restoration controller disables the restoration operation of the restoring unit, the restoration controller enables the restoration operation of the restoring unit after the data received by the receiver is stored in the storage unit, and the restoring unit restores the storing unit to the state at a point of time when or after the restoration controller enables the restoration operation.
