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

Patent number: 10676622Abstract: FF properties of a multilayer coating film configured to exhibit a warm color through a lustrous layer (14) and a translucent colored layer (15) are improved to achieve a metallic textured color having a high-quality color tone. The lustrous layer (14) contains, in a mixed state, a high-reflection flake (21) having a visible light reflectance of 90 % or more and a low-reflection flake (22) having a visible light reflectance that is half (i.e., ½) or smaller than the visible light reflectance of the high-reflection flake (21) as the luster material. When both of the high-reflection flake (21) and the low-reflection flake (22) are projected on a bottom of the lustrous layer (14), a ratio of a projected area of the flakes (21) and (22) on the bottom of the lustrous layer (14) is 100 %.Type: GrantFiled: September 30, 2016Date of Patent: June 9, 2020Assignee: MAZDA MOTOR CORPORATIONInventors: Takakazu Yamane, Keiichi Okamoto, Kouji Teramoto, Ryuji Nonaka

Publication number: 20190099781Abstract: FF properties of a multilayer coating film configured to exhibit a red color through a lustrous layer (14) and a translucent colored layer (15) are improved to achieve a metallic textured color having a high-quality color tone. The lustrous layer (14) is configured such that Y(10°) is 50 or more and 950 or less and that Y(25°) is 0.05 or more and 0.35 or less times the Y(10°), where Y(10°) represents a Y value, of an XYZ color system, of reflected light measured at a light receiving angle of 10° and Y(25°) represents a Y value of the reflected light measured at the light receiving angle of 25° in a case where a light incident angle is 45°. An inclination of a tangent to the spectrum of the spectral transmittance of the colored layer (15) at the wavelength of 620 nm is 0.012 nm?1 or more and 0.03 nm?1 or less, defined as an absolute value.Type: ApplicationFiled: September 30, 2016Publication date: April 4, 2019Applicant: MAZDA MOTOR CORPORATIONInventors: Takakazu YAMANE, Keiichi OKAMOTO, Kouji TERAMOTO, Ryuji NONAKA

Patent number: 5372401Abstract: A sliding roof includes a light transmitting sliding sunroof and a light isolating sliding sunshade disposed beneath the sunroof. The light transmitting sliding sunroof opens a roof opening only while the light isolating sliding sunshade is in its open position. Also, the light isolating sliding sunshade closes the roof opening only while the light transmission sliding sunroof is in its closed position. Damage to the light isolating sliding sunshade, therefore, is prevented.Type: GrantFiled: October 5, 1993Date of Patent: December 13, 1994Assignee: Mazda Motor CorporationInventors: Kozo Odoi, Seiichi Omoto, Ryuji Nonaka, Motoki Yoshida
