Title: Keiichi Umehara: Innovator in Steering Wheel Technology
Introduction
Keiichi Umehara is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of steering wheel technology, holding a total of 3 patents. His innovative designs have enhanced the functionality and safety of steering systems in vehicles.
Latest Patents
One of Umehara's latest patents is a neutral position detector for steering wheels. This device detects the neutral position of a steering wheel and includes a first rotor that rotates integrally with the steering shaft. The first rotor has a slot that is detectable for identifying the steering wheel position. Additionally, a second rotor is rotatable interlockingly with the first rotor, and a power transmission mechanism causes the second rotor to rotate intermittently by a predetermined rotation angle each time the first rotor completes one revolution. When the slots of the first and second rotors align, the detector outputs a signal indicating the position of the steering wheel.
Another significant patent is for a disk designed for a revolution sensor. This disk features a base plate with a circular hole and multiple detection holes. A resin portion is integrally secured to the base plate, providing a holding hole that improves the circularity and coaxiality of the design. This innovation prevents relative movement between the base plate and the resin portion, enhancing the overall performance of the sensor.
