    摘要： A pneumatic tire includes a tread portion provided with three straight main grooves extending continuously in the tire circumferential direction. The three main grooves are arranged asymmetrically about the tire equator such that an exterior main groove, which is one of the main grooves, is disposed in an exterior half, which is one half of the tread portion on one side of the tire equator. An axially inner main groove and an axially outer main groove, which are the remaining two main grooves, are disposed in an interior half which is the other half of the tread portion. Exterior oblique grooves are disposed axially outside the exterior main groove and inclined at an angle .theta. 1 of 45 to 70 degrees with respect to the circumferential direction of the tire. Interior oblique grooves are disposed axially outside the axially outer main groove and inclined reversely to the exterior oblique grooves at an angle .theta. 3 of 60 to 80 degrees with respect to the circumferential direction. Central oblique grooves are disposed between the exterior main groove and the axially inner main groove and inclined in the same direction as the exterior oblique grooves. Furthermore, between the exterior main groove and the axially inner main groove, the angle .theta. 2 of the central oblique grooves are in the range of 20 to 45 degrees with respect to the circumferential direction.

    摘要： A device for controlling the drilling direction of drills includes a cylinder-type housing 6, a first ring-formed component 11 which is located on an inner peripheral surface that is eccentric with respect to the cylinder-type housing 6, a second ring-formed component 12 which is located on the inner peripheral surface that is eccentric with respect to the circular inner surface of the first ring-formed component 11, and hollow-type harmonized reduction gears 13,14 which rotate the first and second ring-formed components 11,12 relatively around their respective centers. A resolver is positioned between the first and second ring-formed components 11,12 and the hollow-type harmonized reduction gears 13,14 to detect the rotating angular position of the first and second ring-formed components 11,12. A fulcrum bearing 8 of the rotating shaft 2 is located at a midpoint between the drill bit and the first and second ring formed components 11,12. A flexible joint 3 is located at the upper portion of the first and second ring-formed components 11,12 and a bearing 15 is further mounted on the flexible joint in order to support the rotating shaft 1.
