Abstract: A method and an apparatus for inspecting a photomask pattern by applying a vector comparing method. Paired optical images intended to be compared are taken from the photomask (1) pattern and converted to paired digital data by optical systems (211,212,41,42) and amplitude distributor (5), the data consisting B, G and W corresponding to high, middle, and low signal amplitude. Paired separated data corresponding to parts of the paired optical images are sequentially and respectively separated from the paired digital data by data separators (81, 82) and the paired separated data are shifted by several matrix elements by data shifters (21,22). The paired shifted data and separated data are respectively synthesized (31,32) providing paired synthesized data from which paired grouped vectors are generated (51, 52) the vectors being defined to be from B to W for the data arranged neighboringly B - W, from B to G for B - G, and from G to W for G - W, in latitudinal, longitudinal, or diagonal direction, with equal magnitude. The numbers of vectors having an equal direction in the paired grouped vectors are respectively summed and compared by a comparator (10) which outputs an information indicative of a defect on the photomask pattern if a difference is detected between summations in any direction.

Abstract: In a pneumatic radial tire for trucks, buses, trailers, etc. formed with circumferential main grooves (10) extending so as to partition ribs (20) and with two narrow grooves (30) arranged near both tire tread ends, tread end ribs markedly wear down as compared with tread center rib, thus resulting in uneconomical irregular abrasion. To overcome this problem, the narrow groove (30) is formed inclined toward a tread center (CL) at an angle (10° or less) with respect to a tread normal (N), with a depth (30d) deeper than that (10d 2 ) of the outermost main groove (10 2 ). The tire thus improved can provide a uniform wear over the tire tread without reducing outer rib rigidity, thus improving rib-tear resistance, tire abrasion resistance, and therefore steering stability and tire life.
