Title: Innovations by Katsumi Ishikawa
Introduction
Katsumi Ishikawa is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of linear motors, holding a total of 2 patents. His work focuses on enhancing the functionality and precision of linear motor systems.
Latest Patents
One of his latest patents is a method of setting the origin of a linear motor. In this invention, a movable member is moved in a preset direction within a linear motor. A characteristic-change position-detecting unit is employed to detect a position where the magnetic characteristic of the magnets has abruptly changed. This detected position serves as an origin-setting reference position. Additionally, a reference position for the absolute position of the magnetic linear encoder is established based on this reference position. Another patent involves a linear motor that connects a position-data converter and a motor-drive control device. The position-data converter receives two-phase, sine-wave analog signals from two first magnetic detectors and converts these signals into position data. Upon receiving a positioning instruction, the motor-drive control device calculates the current value based on the current position signal generated by the position-data converter. The permanent magnets incorporated in the linear motor are also utilized as components of a linear scale.
