摘要:
Since a protecting layer 43 embedded with reinforcing cords 41 is disposed between a tread 35 and a belt reinforcing layer 31, both of the protecting layer 43 and the belt reinforcing layer 31 decentrally bear a large bending force generated when a pneumatic tire 11 runs on a sharp projection or a difference in level. As a result, even if reinforcing elements 33 in the belt reinforcing layer 31 are extended by large tension due to fill internal pressure, increase of strain generated in the reinforcing elements 33 can be effectively suppressed.

There is provided a pneumatic tire in which a belt reinforcement layer is placed and capable of increasing both riding comfort and steering stability. Circumferential bending rigidity of a contact belt ply 25 placed in contact with the belt reinforcement layer 35 is made higher than circumferential bending rigidity of a remote belt ply 24, and thus the belt reinforcement layer 35 having high circumferential bending rigidity and the contact belt ply 25 having next high circumferential bending rigidity are collected near a neutral axis of bending positioned near a boundary thereof. Thus, composite circumferential bending rigidity of the belt layer 23 and the belt reinforcement layer 35 is reduced to reduce a vertical spring constant of the pneumatic tire 11 and increase a ground contact length.

An object of the present invention is to provide an inside drum-type tire testing device, which can significantly improve operability and test precision, reliably has strength high enough to eliminate any concern about strength thereof, and has relatively small size and significantly small floor-occupied area. Specifically, the present invention provides a tire testing device, comprising: an inside drum-type cylindrical rotating drum 1; a fixed support member 2 for surrounding the rotating drum 1 from the outer peripheral side of the drum via rotation guide means 3; and a linear motor 4 provided between the rotating drum 1 and the fixed support member 2, for rotationally driving the rotating drum 1.

A biological chip includes probes immobilized on a circumferential side wall of a discoidal or cylindrical substrate. The probes contain a nucleic acid, a peptide, a saccharide, a lipid, a chemical substance, or a fragment thereof. The disc or cylinder is rotated so as to attain rapid intake of massive assay information obtained from plural probe groups arranged on the circumferential side wall. Mass production of a lot of chips or large-capacity chips is accomplished by constructing the disc or cylinder from a large number of thin sheets or through lamination of plural thin sheets. In blood tests, a biological chip having incubation cells arranged thereon realizes system simplification and miniaturization and resource savings.

The pneumatic tire for two-wheeled vehicles including a plurality of tread rubbers constituting a tread wherein a region occupying 15 to 35% in the center of a stretched tread width, which is obtained by stretching the tread with respect to a tire equatorial plane as the center, is defined as a tread central section; the remaining regions at both ends are defined as tread side sections; regions in the respective tread side sections each occupying 4 to 13% from the corresponding tread end toward the center of the stretched tread width are defined as side-section shoulder-end regions; and the remaining regions of the respective tread side sections are defined as side-section near-center regions, a modulus of the tread rubbers for the side-section shoulder-end regions at 100% elongation is smaller than a modulus of the tread rubbers for the side-section near-center regions at 100% elongation, at least at a tread surface.
摘要:
A pneumatic tire 1 having a toroidal carcass 3 and a belt 7 consisting of belt layers 5, 6 arranged in the outer circumferential side of a crown portion 4 of the carcass 3. Between the adjacent belt layers 5, 6, the cords 8, 9 are crossed with each other with respect to an equatorial plane E of the tire to form cross belt layers. The widest belt layer 6 is a folded belt layer having a body portion 10 and a folded portion 12. A cord 9 constituting the folded belt layer 6 is an organic fiber cord. A narrow belt reinforcing layer 14 of rubberized cords 13 is arranged at least immediately below the width terminal end 11 of the body portion 10 of the folded belt layer 6 which terminal end 11 abuts on the folded portion 12.
