摘要： A pneumatic radial tire has a tread surface extending along a specific curvature plane which includes a first arc with the radius R1 having a center on the tire's equatorial plane and passing through the tire's equatorial point, a second arc with the radius R2 having a center on the tire's equatorial plane and intersecting with the first arc at an intersection distant from the tire's equatorial plane by 0.2 to 0.25 times the tire width SW, and a third arc with the radius R3 passing through a ground contact outer edge point of the ground contact surface, when a standard load is applied, and a belt intermediate height point on the tread surface. In the specific curvature plane, the curvature radius ratio R2/R3 is set in a range from 4 to 12, and the curvature radius ratio R1/R2 is set in a range from 2.6 to 4.6 when the aspect ratio H/SW is 0.55 or less. The tread surface is provided with a main circumferential groove, preferably having a groove width of 0.06 to 0.10 times the tire width SW, extending near the intersection of the first arc and the second arc in the tire circumferential direction for dividing the tread surface into the crown part and an outer shoulder part. Narrow lateral grooves crossing the tire circumferential direction divide the crown part and shoulder part into blocks.

摘要： An apparatus and method in which light from source is kept within a transparent moving roadway and a tire tread is pressed onto one surface of the roadway. The ground contact patch of the tire is observed from the opposite side, and the ground contact area and the non-ground contact area of the tire tread is distinguished clearly. The dynamic behaviour of the ground contact patch of the rotating tire roadway can be observed by means of a camera unit. The information obtained can be utilized for tire design to improve tire performance.

摘要： In a stereoscopic imaging device including a plurality of imaging optical systems, a wide-image in which a principal subject is shifted from the center is taken, and also, a tele-image in which the principal subject is enlarged is taken at the same time. A size of a wide-side frame W, that is, a size of an angle of view of a trimming wide-image is decided based on a size of a tele-side frame T, that is, a zoom magnification of a tele-side imaging optical system, a position of the wide-side frame W displayed in the decided size is arbitrarily moved depending on an instruction from an operation unit, an area delimited by the wide-side frame W moved to any position is clipped from a default wide-image, and thereby, the trimming wide-image is obtained. Thereby, the tele-image which is a telephoto image in which a desired subject is zoomed, and the trimming wide-image which is a wide-angle image in which the subject can exist at a position other than the center of the image are simultaneously obtained.
