Patent number: 9605588Abstract: A supercharger (15) is provided with a bypass pathway (17). A backflow preventer (20) is provided to the air intake pathway (8) between an airflow meter (10) and the bypass pathway (17). The backflow preventer (20) has: a casing (41) formed by locally expanding the cross-sectional area of the air intake pathway; and an inner tube (42) substantially constructing a duct for the mainstream of air intake. The inner tube (42) is supported by a flange portion (50) and the downstream end (42a) opens within the casing (41). During backflow when the bypass pathway (17) opens, a portion of the intake air enters into an exit-side space section (55), and the flow is prevented by the flange portion (50). Consequently, reverse flow is suppressed.Type: GrantFiled: August 6, 2014Date of Patent: March 28, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Takeshi Ookawa, Kiyoshi Ikegaya

Patent number: 9388956Abstract: According to one embodiment, a lighting device includes a light source, and at least one light distribution control member configured to control distribution of light from the light source. The light distribution control member includes a base member higher in refractive index than air, and two optical control layers located opposite each other with a predetermined space therebetween on either side of the base member. The two optical control layers each includes a first region and a second region formed in correlative patterns. The light distribution control member is configured to control the light distribution based on a change of an overlap between the first and second regions depending on a direction of transmitted light.Type: GrantFiled: December 12, 2013Date of Patent: July 12, 2016Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Ken Takahashi, Osamu Ono, Shusuke Morita, Masahiro Yokota, Nobuo Kawamura, Takeshi Ookawa, Hidemi Matsuda, Hideo Oota, Takashi Nishimura
