Title: Akihide Shiratsuki: Innovator in Elevator Technology
Introduction
Akihide Shiratsuki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of elevator technology, holding a total of 17 patents. His innovative designs focus on enhancing the efficiency and accuracy of elevator systems.
Latest Patents
One of his latest patents is an elevator car position detection sensor that determines a phase of an alternating-current voltage corresponding to a frequency of an excitation magnetic field. This invention aims to provide an elevator car position detection sensor capable of suppressing erroneous detection of the presence or absence of a plate. The sensor includes a first coil that outputs an excitation magnetic field to a plate, a second coil positioned opposite the first coil, a shield wall to protect the plate, and a determination circuit to analyze the alternating-current voltage generated across the second coil.
Another notable patent is a cage position detection device. This apparatus detects a car position by performing threshold processing on a voltage caused by an AC magnetic response using an identification plate with a slit pattern and multiple coils. The device features a circuit configuration that can switch between normal operation for detecting the car position and a self-diagnosis operation that verifies the detection irrespective of the identification plate's presence.
