Title: Snow tire
Inventor: NAKAMURA KINYA
IPC: B60C11/18
Filed: 1984-03-09
Abstract: PURPOSE:To provide the ground contact surface itself with edge effect for preventing it from slipping and from damaging the road, by arranging in the crests of a tread pattern of the tire at least two different tread materials having different compression strengths. CONSTITUTION:A tire tread is formed of a first tread member 1 made of an elastic material such as rubber. In the crest portions of the pattern of the tread, a multiplicity of second tread members 2 shaped into thin leaves and having a compression strength higher than that of the first tread member are arranged along the radial direction while the end of each second tread member 2 is exposed in the ground contact surface. The second tread members thus exposed has a linear shape as shown by A in the drawing, for example, when viewed from the ground contact surface side. Accordingly, the local difference between said tread members 1 and 2 in bearing pressure allows the second tread members 2 to bite the ground surface or to effectively utilize fine uneveness on the ground surface, so that edge effect can be obtained.

Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To increase the speed of a measurement by performing the switching of a modulated light to an external optical path and to reference light path by an optical path switching means for electrically changing the polarizing characteristic of the modulated light. SOLUTION: A polarizing axis controller 4 outputs a linear polarized pulse light inputted from a polarizer 3 to a polarizing divider 5 in the state where the polarization axis is left as it is, or after it is rotated 90 according to a polarizing axis control signal. An arithmetic processing circuit 13 lays the polarization control signal to the controller 4 into ON state to set a reference optical path measurement mode where the light passes a reference optical path, and outputs a start signal simultaneously to a pulse driving circuit 1 and a time measuring circuit 12. The circuit 13 calculates the distance of the reference optical path from the time measurement data and the luminous flux. The circuit 13 then lays the polarization control signal into OFF state to set an external optical path measurement mode where the light passes an external optical path. The distance of the external optical path is calculated from the time measurement data inputted to the circuit 12 and the luminous flux. The reference optical path length is subtracted from the external optical path length to determine the distance.
