Title: Innovations by Yoshiki Nota in Elevator Technology
Introduction
Yoshiki Nota is a notable inventor based in Tokyo, Japan, recognized for his contributions to elevator technology. He holds three patents that showcase his innovative approach to improving elevator maintenance and safety.
Latest Patents
One of his latest patents is an elevator rope maintenance method. This method involves an optical rope diameter measuring device positioned along the path of a wire rope. During maintenance inspections, the device measures the rope diameter at multiple points while the elevator operates in test mode. The diameter reduction at each point is recorded as the first diameter reduction. In subsequent inspections, the diameter is measured again to determine a second diameter reduction. This data allows for predicting when the diameter reduction will reach a predetermined threshold, indicating the optimal time for rope replacement.
Another significant patent is the elevator rope elongation measuring device. This device includes a camera that photographs one or more elevator ropes. An image processing unit analyzes the captured images, detecting the rope's external form as a regular hill and valley shape. It converts the cyclic length of this shape into actual dimensions, allowing for the calculation of elongation without the need for preliminary sensor installation or database creation.
