Title: Innovations by Takeshi Ohta
Introduction
Takeshi Ohta is a notable inventor based in Toyonaka, Japan. He has made significant contributions to the field of tire technology, holding a total of 4 patents. His work focuses on enhancing the performance and safety of tires, particularly in challenging conditions.
Latest Patents
One of his latest patents is for a pneumatic tire with monofilament metallic belt cords. This innovative tire design includes a belt that is radially disposed outside the carcass in the tread portion. The belt consists of two cross plies of monofilament metallic cords laid at angles between 15 to 30 degrees with respect to the circumferential direction of the tire. Each monofilament cord is composed of a waved single filament, which has a circular sectional shape with a diameter ranging from 0.40 to 0.50 mm, or alternatively, a non-circular sectional shape with an aspect ratio between 0.65 and 0.95 and a cross-sectional area between 0.09 to 0.20 sq.mm.
Another significant patent by Ohta is for a studless tire that features a tread including fibers oriented in the thickness direction. This studless tire is designed to perform exceptionally well on snow or ice roads. It incorporates non-metal staple fibers with an average diameter of 1 to 100 micrometers and an average length of 0.1 to 5 mm, which are dispersed in a diene rubber. The fibers are oriented in the thickness direction of the tread, ensuring that the complex elastic modulus in the thickness direction and the elastic modulus in the circumferential direction satisfy specific performance criteria.
