Abstract: The present invention provides a herbicidal composition containing: at least one compound (I) selected from a compound represented by a formula (I) (wherein R1 represents a substituted or unsubstituted C1-6 alkyl group or the like, R2 represents a substituted or unsubstituted C1-6 alkyl group or the like, R3 represents a hydrogen atom, a substituted or unsubstituted C1-6 alkyl group or the like, and Q represents a substituted or unsubstituted phenyl group or the like) or a salt thereof; and a compound (II) having herbicidal activity such as haloxyfop-methyl, clethodim, S-metolachlor, epyrifenacil, isoxaflutole, sethoxydim and tepraloxydim.

Abstract: Provided is a method for adjusting an image pickup device, wherein a position of an image pickup element is set to an initial position, a uniform luminance surface is picked up, a luminance distribution on an image pickup surface is calculated, whether data of the luminance distribution on the four corners of the image pickup surface substantially agree with each other or not is judged, and such operations are repeated until the data substantially agree with each other by moving the position of the image pickup element by a predetermined value. By using the position of the image pickup element obtained when the data substantially agree with each other as information of the center position, the center position of the image pickup element can be adjusted in a short time and an image having a natural luminance distribution can be obtained.

Abstract: A heavy duty radial tire and rim assembly comprising a pair of bead cores, a carcass, a belt, and a pair of bead apexes, wherein in at least one of the bead portions, when the tire is mounted on a normal rim specified for the tire and inflated to a normal pressure, a thickness center line of a carcass turnup portion between two points is cured and located axially inward of a straight line drawn between the two points, the quotient (X/HR) of the axial distance (X) of the inner end (Q2) of the bead core from a bead heel point (Q1), to the height (HR) of a flange of the normal rim is in a range of 0.8 to 1.05, wherein the bead heel point (Q1) is defined as in intersection of an extension of the outer surface of the bead portion with an extension of the bead base, and the quotient (Y/HR) of the radial distance (Y) from the radially outer end (Q3) of the flange of the rim to the radially outer end (Q4) of the bead core, to the height (HR) of the flange of the rim is in a range of 0 to 0.3.

Abstract: A tire for a motorcycle comprising a tread, sidewalls extending inwardly from both ends of the tread in a radial direction, bead portions positioned at the radially inward ends of the sidewalls, a toroidal reinforcement carcass composed of reinforcement cords which extend approximately parallel with each other in the radial direction of the tire and of which both end portions are turned up around bead cores, a breaker arranged on the radially outer side of the carcass, the breaker comprising reinforcement tire cords whose tensile strength is not less than 7 g/d and initial modulus is not less than 200 g/d laid at angles of 10.degree. to 45.degree. to the circumferential direction, and a band over the breaker and having a width greater than the breaker so as to axially extend past the outermost edges of the breaker and comprising parallel reinforcement cords laid at angles of 10.degree. to 25.degree.

Abstract: Radial tires for motorcycles comprising a tread portion, side wall portions, bead portions, a carcass, bead apexes made of a rubber having a high hardness, and optionally reinforcing cord layers arranged outside the bead apexes, said tread portion having shoulder grooves at the shoulder portion thereof and center grooves at the center portion thereof and the depth of the shoulder grooves being from 5 to 50% of the depth of the center grooves, whereby cracking of the shoulder groove bottom caused by providing the bead apexes made of a hard rubber or the reinforcing cord layers is prevented.

Abstract: A working vehicle having a working device mounted on a swivel base rotated by a hydraulic motor. There is provided a control system which causes the swivel base to start and stop smoothly at highest possible standard speeds which are preset for an entire swivelling range.

Abstract: Radial tires for motorcycles comprising a tread portion, side wall portions, bead portions, a carcass, a breaker, and optionally a reinforcing cord layer arranged outside the carcass and extending from one bead portion to the other bead portion and bead apexes made of a hard rubber, said tread portion having a plurality of longitudinal grooves in the circumferential direction at an angle of at least 5.degree. with respect to the cords of the most outer ply of the breaker. The motorcycle radial tires of the invention have an improved transverse stiffness at the side wall portions and moreover do not cause cracks at the bottom of the grooves in the tread portion.

Abstract: An excavating vehicle according to the present invention comprises an excavating apparatus rotated by a hydraulic actuator, said excavating apparatus being stopped automatically and smoothly at predetermined positions with a simple operation.
