Title: Ken Okuyama: Innovator in Torque Measurement Technology
Introduction
Ken Okuyama is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of torque measurement technology, holding a total of 3 patents. His innovative designs and methods have advanced the capabilities of torque measuring devices, making them more efficient and reliable.
Latest Patents
One of Ken Okuyama's latest patents is a torque measuring device that includes a coil unit with a detection coil. This coil is designed to change voltage in response to variations in the magnetic permeability of a magnetostrictive effect section of a rotating shaft. The device features a back yoke arranged coaxially around the coil unit and a holder that secures both components. An electronic circuit generates an output voltage based on the detection coil's voltage, ensuring that the clearance between the coil unit and the back yoke is regulated for linear output voltage changes with temperature variations.
Another notable patent is the manufacturing method for the torque measuring device. This method involves testing samples with the same configuration to determine a coil balance, which is the ratio of resistance values in a bridge circuit. The process also includes measuring resistance values to find the coil balance and the temperature change rate for the device being manufactured.
