Title: Innovations of Junichi Tanino
Introduction
Junichi Tanino is a prominent inventor based in Inazawa, Japan. He has made significant contributions to the field of elevator technology, holding a total of 10 patents. His work focuses on enhancing the efficiency and safety of elevator systems.
Latest Patents
One of his latest innovations is an elevator with a separated speed governor and position detector. This invention features a transmission sheave attached to a mount structure fastened to a guide rail. A speed governor rope, which is suspended from a speed governor, is coupled with an elevator car that ascends and descends in a shaft. The rope is wound on the transmission sheave, and an idler pulley is included to increase the winding angle with respect to the transmission sheave. Additionally, a position detection apparatus is provided to detect the position of the car in the shaft based on the rotation of the transmission sheave. This apparatus can be installed in an empty space in the shaft, eliminating the need for repairs to an existing speed governor, thus saving repair costs.
Another notable patent is a speed detector device for elevators. This device is capable of making speed measurements in the relatively slow speed region of an elevator. It comprises a pulse generator that generates two-phase pulse signals with a predetermined phase difference. A pulse processing circuit outputs corresponding triggers in response to the rising and falling edges of each pulse signal. The arrangement allows for accurate speed measurements, even in the absence of a rising edge during a CPU read cycle.
