Abstract: A pneumatic tire has a belt layer arranged in a tread portion. The belt layer includes a first belt ply, a second belt ply arranged in an outer peripheral side of the first belt ply, and a third belt ply arranged in an outer peripheral side of the second belt ply. The third belt ply is provided with a circumference reinforcing portion which is positioned in an inner region of a land portion, and a lateral reinforcing portion which is positioned in an inner region of a main groove. The circumference reinforcing portion is structured such that an angle of a cord with respect to a tire circumferential direction is less than 45°. The lateral reinforcing portion is structured such that an angle of a cord with respect to the tire circumferential direction goes beyond 45°.

Abstract: A pneumatic tire comprises a plurality of main grooves extending along a tire circumferential direction, and shoulder lateral grooves extending to an outer side in a tire width direction from a shoulder main groove positioned in an outermost side in the tire width direction among the main grooves, the main grooves and the shoulder lateral grooves being arranged on a tread surface, wherein a depression is formed on a wall surface of a land portion facing to the shoulder lateral groove, in a state in which it is not exposed to a surface of the land portion, and wherein the depression is formed in such a manner that a height of the depression in a depth direction of the shoulder lateral groove is reduced toward an inner side in the tire width direction, and an exposure length of the depression becomes longer in accordance with a progress of an abrasion of the land portion.

Abstract: A sipe extending in a tire width direction is provided in a land part (block) of a tread shoulder region, and the sipe is configured to include a first sipe part, a second sipe part having a groove width larger than the first sipe part and a third sipe part larger than the second sipe part. The first sipe part is formed over the whole of a sipe length direction in an opening side region of the sipe and the whole of a sipe depth direction in an inner region on the side of a tire equator; the third sipe part is formed in an outer region on the side of a tread ground contact end in a sipe bottom part region; and the second sipe part is formed in a region between the first sipe part and the third sipe part.

Abstract: The present invention relates to a color difference signal processing circuit of a video tape recorder (VTR) by a timeplex system. The hue of the picture face is adapted not to change with variation in amplitude and variation in DC level during the reproduction of the tape recorded by the VTR.
