Latest Patents

Tominaga's latest patents include a curvature adjustment method for stator blade segments, a method for manufacturing the stationary body of an axial-flow rotary machine, and a curvature adjustment jig for stator blade segments. The curvature adjustment method is applied to an arc-shaped stator vane segment that has multiple stator blades arranged side by side on the outer peripheral side of an arc-shaped inner coupling member. This method involves a jig preparation step, a jig mounting step, and a curvature adjustment step. In the jig preparation step, a curvature adjustment jig and a distance adjustment mechanism are prepared. The jig mounting step involves fixing the first end of the distance adjustment mechanism at a first position of the inner coupling member and the second end at a second position. Finally, the curvature adjustment step operates the distance adjustment mechanism to change the distance between the first and second ends of the curvature adjustment jig.

Another significant patent is the plasma generating apparatus and semiconductor manufacturing method. This apparatus generates high-density plasma, even in the central portion of the plasma generating zone. It comprises rectangular electrodes, a rectangular fistulous discharge electrode surrounding the plasma generating zone, and a vacuum chamber of rectangular cross-section. Permanent magnets surround the discharge electrode, producing predetermined magnetic lines of force that extend approximately parallel to the central axis of the discharge electrode. The design ensures that the magnetic lines of force passing through the central portion of the plasma generating zone do not intersect with the electrodes.
