Patent number: 11242865Abstract: Structures are formed in a shape protruding from a wing surface, and a plurality of riblets are formed in a shape depressed from the wing surface. A first cross section obtained by cutting the structure by a flat face that is parallel to a flow and perpendicularly intersects with the wing surface has an inclined side that extends from a point on the wing surface to a top that is a point apart from the wing surface. An inter-structure flow channel is formed between two adjacent structures among the plurality of structures. The area of a face in one of the two structures and the area of a face in the other structure with which a fluid flowing in the inter-structure flow channel comes into contact are different from each other. Accordingly, peeling of the flow can be suppressed and the frictional resistance of the flow can be decreased.Type: GrantFiled: November 30, 2017Date of Patent: February 8, 2022Assignee: HITACHI, LTD.Inventors: Mariko Miyazaki, Akihiro Miyauchi

Patent number: 9261631Abstract: A diffraction grating excellent in surface precision and allowing its miniaturization and weight reduction and a method for manufacturing the same. The present invention includes: a glass substrate having a thickness of 0.5 mm to 8 mm; a resin-made microstructure body having an unevenness pattern and formed on one surface of the glass substrate; and a flat resin layer formed on the other surface of the glass substrate. Even if the glass substrate has surface precision of ?/2 or greater, the replica of the diffraction grating, in which the microstructure body is not influenced by the surface precision of the glass substrate and which is excellent in surface precision, can be manufactured by the flatness of the resin layer. In addition, since the glass substrate can be made thin, the miniaturization and weight reduction of the diffraction grating can be achieved.Type: GrantFiled: February 1, 2013Date of Patent: February 16, 2016Assignee: Hitachi High-Technologies CorporationInventors: Kenji Kawasaki, Masahiko Ogino, Akihiro Miyauchi
