Abstract:
The present is intended to provide a studless tire capable of enhancing ice performance without complicating the structure and the material.The studless tire 10 is configured such that the width 2W of a radially outwardly disposed belt ply 12 of belt plies constituting a belt 8 is 60%-70% of a maximum tire width MW.
Abstract:
Apparatus is disclosed for sensitively detecting and quantitatively analyzing biological and biochemical substances. Charged into a cell is a test molecule labeled with a fluorescent dyestuff. An exciting optical system transmits plane polarized light from a light source into the labeled molecule to excite the molecule, and a polarizing optical system takes up fluorescent light emitted from the molecule. A photomultiplier is arranged to measure the fluorescence intensities of parallel and perpendicularly polarized light from the molecule. A calculator coordinated with the polarizing optical system computes and converts the fluorescence intensities into the degree of polarization of the molecule.
Abstract:
A pneumatic tire is disclosed, adapted to highly effectively combine on-ice and on-snow performances. The pneumatic tire includes block groups (G) formed by polygonal blocks (10), which are arranged closely in a tread portion (1). The polygonal blocks (10) are formed by grooves (9) including first groove (9a) with a groove width (W9a) between the polygonal blocks 10 neighboring with each other in the tire circumferential direction. The groove width (W9a) of the first grooves (9a) is larger than a groove width (W9b) of second grooves (9b) between the polygonal blocks 10 neighboring with each other with a zigzag pattern.
