Abstract: A tread portion 2 of a tire 1 includes a plurality of shoulder blocks 11 and a plurality of middle blocks 12. An inner edge 11B in the tire axial direction of a tread surface of each shoulder block 11 protrudes on an outer side in a tire radial direction with respect to a virtual profile 18. A side surface S on the inner side in the tire axial direction of each shoulder block 11 includes one first side surface S1 extending from the inner edge 11B toward a groove bottom, and at least one second side surface S2 extending from a bottom side end of the first side surface S1 toward the groove bottom, and the second side surface S2 is a surface inclined toward the inner side in the tire axial direction relative to the first side surface S1.

Abstract: A warehousing and shipping operation support system stores first coded information contained in an optical recognition code attached to each of a plurality of objects, acquires the first coded information contained in an optical recognition code attached to a target object out of the plurality of objects, automatically acquires location information of a working radio communication terminal, and associates the stored first coded information with the acquired location information of the working radio communication terminal.

Abstract: A motorcycle tire comprises a carcass having a bias structure, a band comprising a jointiess ply, and a tread rubber disposed on the radially outside of the band. The loss tangent of the tread rubber at a temperature of 0 deg C. is larger in a tread crown region than in tread shoulder regions. The carcass comprises an outer carcass ply of carcass cords. The angles of the carcass cords with respect to the tire circumferential direction are smaller in the tread crown region than in the tread shoulder regions.

Abstract: A motorcycle tire is provided in the tread portion with first inclined main grooves and second inclined main grooves which are arranged alternately in the tire circumferential direction while inclining in opposite directions. The first inclined main grooves extend from a first tread edge toward a second tread edge across the tire equator and terminate at the respective second inclined main grooves which extend from the second tread edge toward the first tread edge across the tire equator and terminate at the respective first inclined main grooves which are respectively next to the above-said first inclined main grooves. A first region, which is delimited by the first tread edge, two of the first inclined main grooves and one of the second inclined main grooves, is provided with blocks whose ground contacting top surfaces have vertices each having an angle of not less than 45 degrees.

Abstract: A motorcycle tire is provided with a tread pattern made up of circumferentially alternately arranged first and second pattern units. The first pattern unit is substantially mirror symmetrical with the second pattern unit. Each pattern unit comprises a main oblique groove and first and second auxiliary oblique grooves, each of which is a bent groove having a bent position and composed of a steeply-inclined part and a mildly-inclined part, in the main oblique groove, the steeply-inclined part extends from a start position on one side of the tire equator to the bent position on the other side of the tire equator, while inclining to one tire circumferential direction; and the mildly-inclined part extends from the bent position to the adjacent tread edge, while inclining to the above-mentioned one tire circumferential direction.
