Latest Patents
One of his latest patents is an imprint apparatus and imprint method. This invention includes a mold that forms a pattern in a resin on a base plate, a press unit that presses the mold against the resin, and a flow channel that is formed by a wall of the mold and a surface of the resin. The apparatus also features a supply unit that supplies air to the flow channel, ensuring that air flows along the wall and the surface. The supply unit is designed to provide air with a first pressure to the flow channel when the mold makes contact with the resin.
Another significant patent is an optical rotary encoder with a correction method that reduces variation in the distance between a rotation body and a light receiving unit. This optical rotary encoder includes a light source, a rotation body with a reflecting diffraction grating, and a light receiving unit with multiple light receiving elements. A synthetic unit combines output signals from these elements to obtain a signal representing a fringe pattern component at a certain cycle. The detection unit then detects the direction based on the signals obtained, allowing for precise measurements.
