Latest Patents

One of Okamoto's latest patents is a surface pressure measuring device. This innovative device includes an abutting plate, a lift, a probe, a piezo actuator, and a controller. A pinhole is formed in the abutting plate at an abutting surface that contacts a target. The lift mechanism allows the target to compress against the abutting surface to a predetermined thickness. The probe is designed to be inserted through the pinhole and is movable in the axial direction. The piezo actuator maintains a state where the tip surface is flush with the abutting surface, resisting the repulsive force from the target while the lift engages. The controller calculates the local surface pressure of the target based on the load applied to the probe and the area of the probe's tip surface.

Another significant patent by Okamoto is related to a rotating electric machine and its cooling system. This invention improves the heat discharging properties of the stator coil end in a rotating electric machine. The motor consists of a stator and a rotor, with the stator featuring a stator core and resin mold coil ends at both axial ends. Column-shaped projections are strategically placed on the axial side surfaces of the resin mold coil ends. Cooling oil is supplied from above the resin mold coil ends, effectively cooling them and enhancing the overall performance of the machine.
