Patent number: 11850780Abstract: A resin member includes: a resin substrate; and a micro-embossed pattern and having a plurality of recesses and a plurality of protrusions. The plurality of protrusions includes: a plurality of first protrusions; and a plurality of second protrusions having a height of from ¼ to ¾ of the height of the first protrusions. A distance between peaks of two adjacent ones of the plurality of protrusions ranges from 100 ?m to 500 ?m. The number of the minute regions having an angle of inclination of from ?10° to 10° with respect to the reference plane ranges from 78% to 95% of the number of all of the minute regions included in the micro-embossed pattern corresponding to the predetermined distance, and the number of the minute regions having an angle of inclination of from ?1° to 1° ranges from 25% to 40% of the number of all of the minute regions.Type: GrantFiled: November 15, 2019Date of Patent: December 26, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Sakura Nakano, Masaaki Akamine, Kaname Sawai, Akihiro Hosono, Shuhei Narita, Yu Tanaka

Patent number: 11845496Abstract: A vibration damping structure includes a panel which is a structure and a damping member joined to the panel. The damping member has a plurality of joined portions joined to a mating surface of the panel through respective joined surfaces in the X direction, and a plurality of spacing portions recessed toward the side opposite to the panel in the Z direction between adjacent joined portions. The damping member is formed such that the damping member is higher in damping than the panel and a resonance frequency of the damping member is formed such that it is substantially the same as a primary resonance frequency of the panel.Type: GrantFiled: February 9, 2022Date of Patent: December 19, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Kaito Nakamura, Miho Kurata, Sakayu Terada, Shuhei Narita, Daisuke Yamada, Toshitaka Miyoshi

Patent number: 11414288Abstract: In a method and a device for correcting meandering of a strip material in an apparatus that performs conveyance of the strip material at a non-contact state by floating a continuously traveling strip material by a floater group, the strip material is tilted by forcibly changing a height position in the widthwise direction of the strip material in at least one of a zone between the most upstream floater in the floater group and a conveyance roll located immediately upstream of such a floater, a zone between two adjacent floaters, and a zone between the most downstream floater in the floater group and a conveyance roll located immediately downstream of such a floater, whereby the height position in the widthwise direction of the strip material above the floater is changed and a static pressure applied to the strip material above the floater is changed to correct meandering thereof.Type: GrantFiled: November 9, 2018Date of Patent: August 16, 2022Assignee: JFE Steel CorporationInventors: Hirokazu Kobayashi, Yuhei Iwami, Shuhei Narita, Masanori Hoshino

Patent number: 10864946Abstract: In order to increase road noise transmission loss, a double-wall panel includes a core material. The core material is enclosed between an outer wall and an inner wall facing each other, and has at least a predetermined thickness across the panel in all in-plane directions of the walls. The core material has a specific surface area of 20,000 (mm2/cm3) or more, where the specific surface area is defined as a surface area per unit volume.Type: GrantFiled: October 25, 2018Date of Patent: December 15, 2020Assignee: MAZDA MOTOR CORPORATIONInventors: Tomoya Yoshida, Shuhei Narita, Keisuke Yamakawa, Takashi Sasaki, Ryuji Nonaka, Masanori Ishikawa, Katsumi Shiraishi, Seiji Nakano
