Latest Patents

Ryuichi Sato's latest patents include a "Coil Spring Modeling Apparatus and Method Utilizing a Torsion Detection to Control an Actuator Unit." This apparatus features a first attachment member on a lower spring seat and a second attachment member on an upper spring seat. It incorporates an actuator unit formed of a Stewart-platform-type parallel mechanism, a hydraulic pressure supply device, a torsion detection mechanism, and a controller. The torsion detection mechanism consists of displacement gauges, such as a linear variable differential transformer, which are placed on hydraulic cylinders to detect displacement amounts relative to their reference lengths. The controller calculates the relative torsional angle between the two attachment members based on the detected displacement.

Another notable patent is the "Coil Spring Modeling Apparatus and Method of the Same." This apparatus also includes a first attachment member on a lower spring seat and a second attachment member on an upper spring seat. It features an actuator unit formed of a Stewart-platform-type parallel mechanism, a spring height detection mechanism, and a controller. The spring height detection mechanism is similarly constituted of displacement gauges, which detect displacement amounts relative to the reference lengths of the hydraulic cylinders. The hydraulic pressure supply device is controlled by the controller to supply fluid pressure according to the detected displacement.
