Patent number: 8131154Abstract: A visible light communication apparatus is constituted with a transmitter for illuminating and projecting visible light on which an information signal is superimposed from a lamp fitting and a receiver for receiving the visible light to take out the information signal superimposed on the visible light. The transmitter modulates a transmission information signal, driving a light projecting element of the lamp fitting so as to superimpose the transmission information signal on the visible light of the lamp fitting, thereby radiating white light containing a blue light component as visible illumination light. The receiver receives the white visible light containing the blue light component radiated from the transmitter and generates a receiving information signal from the light receiving signal on a receiving circuit. A blue light photodiode which receives blue light at the highest sensitivity to output a light receiving signal is used as a light receiving element of the light receiving unit.Type: GrantFiled: March 27, 2009Date of Patent: March 6, 2012Assignee: Planners Land Co., Ltd.Inventors: Fumitaka Murayama, Hiroyuki Kurokawa, Naoyuki Furuta

Patent number: 7767911Abstract: A grommet (1) has a central shaft (2)through which a wire harness (5) is inserted. A circular connection portion (31) is provided continuously to the periphery of the central shaft(2.) A convex cross-sectionally V-shaped ring-like lip (32) is extensibly provided to the circular connection portion (31) in the direction of the center of the central shaft. A flange portion (33) is provided continuously to the lip portion (32.) When the grommet (1) is assembled to a body panel (10,) the lip (32) of the grommet (1) is extended in the direction of the center of the central shaft (2) of the grommet (1,) thereby reducing the diameter of the lip (32.) Then, the lip(32) is inserted into the through hole (12) of the body panel (10.) Thus, a low insertion force is sufficient when the grommet is inserted thereinto. Consequently, the assemblability of the grommet (1)is enhanced.Type: GrantFiled: March 7, 2008Date of Patent: August 3, 2010Assignees: Yazaki Corporation, Honda Motor Co., Ltd.Inventors: Nozomi Kawasaki, Yasuyoshi Serizawa, Tatsuo Shimada, Tetsuya Mitani, Hiroyuki Kurokawa
