Title: Spike tire with spike emerging when slippage is generated between road surface and tire
Inventor: SAKAMOTO HIROSHI
IPC: B60C11/16
Filed: 1986-12-10
Abstract: PURPOSE:To prevent a tire and road surface respectively from slippage and damage by providing swingably spherical bodies provided with frictional bodies, spikes, etc., for the road surface on the tread surface of tire to put the spikes in and out of the tread surface by swinging the spherical bodies in response to the presence of slippage of tire. CONSTITUTION:When in ordinary travelling a tire 10 is rotated under the condition of no slippage between the tire and road surface 12, since fore, aft, right and left forces from the road surface 12 are not applied to frictional bodies 8, a spherical shaft 3 mounted on a disk 1 and a spherical body 7 hold the neutral position by the elasticity of rubber 13. Thus, a conical spike 9 does not abut against the road surface 12 to prevent the road surface 12 from damages due to the conical spikes 9 while accomplishing the smooth rotation of tire 10. On the other hand, when the tire 10 begins to slip in the direction A, spherical bodies 7 rotate about the center of the spherical shaft 3 by the friction between the road surface 12 and the frictional body 8 while flattening the rubber 13. Thus, the conical spikes 9 abut against the road surface 12 for braking.

Abstract: PURPOSE:To increase the tilt angle of a bistable ferroelectric liquid crystal element and to improve the transmissivity at the time of the opening of a picture element shutter by crossing axes of uniaxial orientation which have different orientation control force on a surface where two substrates contact liquid crystal. CONSTITUTION:Uniaxial oriented surfaces formed on an upper and a lower substrate have their axes 41 and 42 of uniaxial orientation crosses at 45 deg. in the opposite direction from a direction of twist arraying when applied with no electric field.
